As a high-end brand built by Chery, Star Road has gained a certain market voice since its launch, relying on Lingyun, Lanyue, Zhuifeng and other models. On February 21st, Starway Eta Ursae Majoris, built on the platform of Starway M3X Mars Architecture 2.0, was officially launched, with a total of six configurations, with the price range of 152.8-202.8 million yuan.

The Aesthetic Design Language of Atlantis Light

The appearance of Starway Eta Ursae Majoris is based on the aesthetic design language of Atlantis light, and a lot of popular elements are injected. It is worth noting that although it is a fuel vehicle, its modeling temperament can easily be mistaken for a pure tram. The design of the front face continues the avant-garde style of the previous concept car. The grille adopts a rhombic grille with frameless design. The penetrating LED headlights across the front face and the daytime running lights on both sides outline the "sigma" similar to the Greek symbol, which is full of recognition.

Xiongshi ecological intelligent cockpit

As the first model of Lion Eco-2023, Starway Eta Ursae Majoris’s EEA4.0 advanced electronic and electrical architecture, supported by Gigabit Ethernet, OTA for the whole vehicle and separation of hardware and software for Autosar, can continuously refresh the car experience through continuous iterative upgrading.

In the rear row treatment, Eta Ursae Majoris has an adjustable backrest angle and an independent fresh air system. In terms of hearing enjoyment, SONY 14 speakers are also equipped to create a 360-degree sound experience for passengers in each seat.

Flying fish extrasensory chassis /2.0TGDI engine

In terms of power, Eta Ursae Majoris is equipped with a 2.0TGDI engine with a maximum power of 261 HP (192kW) and a maximum torque of 400 Nm, matching the 7DCT gearbox. It is reported that PHEV models will be launched in the future.

It is worth noting that Starway Eta Ursae Majoris is equipped with a brand-new flying fish extrasensory chassis. The CDC electromagnetic suspension system equipped with this chassis can collect the dynamic data of road surface, car body and wheels in real time through five car body attitude monitoring sensors, four electromagnetic dampers and a controller, and actively adjust the suspension damping in time. While realizing the intelligent control of vehicle attitude, CDC electromagnetic suspension system takes into account the improvement of comfort and handling.

Officials pointed out that CDC electromagnetic suspension system can reduce the vehicle’s head-up phenomenon by 36%, weaken the braking nod by 30%, improve the anti-roll ability and isolation performance by 5% and 40% respectively, and improve the overall suspension comfort performance by 30%.

Thanks to the full-scene intelligent four-wheel drive system, all-terrain technology system and freewheeling steering system, under extremely complicated road conditions, the rear axle can achieve "a response within 100ms and a maximum torque output of nearly 3000N·m". At the same time, with the assistance of Bosch’s new generation of intelligent brake-by-wire system, the ability to limit slip is stronger, more accurate and easier to get out of trouble.

The all-terrain science and technology system also provides seven driving modes: economy, standard, sports, snow, mud, sand and off-road, which can unlock multiple driving and control scenes for users. In addition, common functions such as off-road crawling, perspective chassis and four-wheel drive dynamic vector display are also absent. Bosch’s new generation DP- EPS steering system not only provides low-speed light, high-speed and steady steering force, but also improves its response speed by 20% under the master chassis steering adjustment.

In terms of safety, based on M3X Mars Architecture 2.0, Xingtu Eta Ursae Majoris meets the global NCAP crash test standard, and is equipped with Bosch’s new generation intelligent brake-by-wire system, which greatly improves the braking response and shortens the braking distance with a build-up time of less than 150 ms. With the help of this technology, the brake pedal is not only adjustable, but also has dual modes of comfort and movement to meet the needs of users in different driving environments.

The reason for the purchase is that a number in Shenzhen is 95 thousand, and this Qin 80 is less than 150 thousand, and the car is equivalent to 50 thousand, which is worth it There is a car at home, and my wife drives the children to and from work. I take the subway every day. On that day, I went to see the car with my relatives, but they couldn’t shake the number, so I had to buy an electric car or a hybrid car. Perhaps the best choice is Qin, only a Qin 80, white, and there is no other choice in configuration. My wife asked me if I needed it. Of course I do. Driving is more comfortable than the subway. So buy. I am also afraid that new energy will have to be shaken in the future, but I can’t play with the government.

I paid a deposit of 5,000 yuan, saying that there is an existing car, and the new energy should be shaken, but it will be available soon in 3.5 days. Then I chose the number, which seems to be optional. I didn’t choose it, but I chose it from the five groups given by the website. Finally, I chose the one with 6 and 8, which was not bad and quite satisfactory.

Then I went to see the car selected for me in 4s, and the appearance was no problem. The car in December, the mileage was less than 10. Then go back and wait for the cards to come down. I have been waiting for a long time, and I will buy more cars at the end of the year. Today, on January 23, the iron card came down, which was slow enough, and the card was renewed once.

The car price is 146 thousand, the loan is half, interest-free, and the handling fee is 3000, which is 149 thousand in total. You can’t bargain.

I didn’t want to send chassis rust prevention, floor mats, perfume pillows or anything, but I also threw them away if I wanted them. There are ordinary charging cables and charging piles on board, but they are not installed. There is no spare tire, but there is tire repair liquid.

I also took photos when I picked up the car and brought big red flowers to the car. Although it is vulgar, it is interesting. And tied a red tape, and I threw it away.

Positive, more domineering.

The front side is 45 degrees, with daytime running lights. I like it.

On the side, the wheels and hubs are all black, which makes them feel suspended. Automatic folding rearview mirror. I like it.

45 degrees behind, controversial taillights.

Large tablet computer, can hold a lot of software, WeChat and so on, almost all operations can be done on the computer, colleagues say the screen is so big. Like Tesla.

Bought a Mijia driving recorder.

There are lights in the glove box. There are also lights in the front footsteps.

There are lights on the door, too.

There is a lot of space in the back row.

Summary:

Advantages are license plate delivery, many functions, I prefer automatic headlights, wiper spray is foggy, automatic folding rearview mirror, one-button start, large screen, automatic internal circulation when parking, one-button lifting window, skylight, front camera, rear camera, quiet when pure electricity, headlights left low and right high, saying that the other party will not be blinded when passing.

The disadvantage is that it takes more than 8 hours to charge slowly before running 80 kilometers. It is a bit more fuel-efficient to run with mixed oil, and it is louder and more expensive to charge with oil. In many places, there are charging piles, but there is no electricity, or you have to buy hundreds of pieces of double-ended wires yourself. Mixed power consumption is less than 40, and oil consumption is more than 40. I am afraid that the start of the channel will be bad for the engine. The community will not install charging piles, saying that it will be unified and safe in the future. I don’t know if it will wait until the year of the monkey. The unit and leaders said that it can be charged, which is more convenient. The workmanship is not particularly good, but at least it is worth the price. BYD is getting better and better and hopes to be strong.

Buying suggestions, big cities like Shanghai and Shenzhen can buy them if they can’t shake the number. After all, Shenzhen has a number of 95,000, and there is one worry. Is there radiation when using batteries? Is there much radiation? The first insurance is 3500 kilometers or half a year. At present, both oil and electricity are used. After all, the engine should be run in.

I’m tired of typing on my mobile phone. If you have any questions, you can leave a message. I’ll try my best to reply. I’m in a hurry and my level is limited. I may have left something unsaid or wrong. Please forgive me. I was the first in our company to buy BYD Qin, and there was no hybrid or electric car before. I believe there will be more and more in the future.

In terms of power, it only takes 5: 9 seconds to accelerate 100 kilometers. The power is strong, overtaking is powerful, and the acceleration is fast. I am satisfied. I’m 176, and the front row and back row are fine. A well-behaved car with high configuration and many functions is worth buying. The highest tone is the taillights and the big screen.

The interior is also luxurious.

The appearance is also relatively durable.

The chassis is a little low, so be careful of uneven roads. You’ll knock it.

A car with high cost performance, I hope to drive for a long time. If you spend 100,000 yuan to buy a license plate, and then 50,000 yuan to buy a car, you can’t buy anything new, and you can’t buy anything good second-hand, so I don’t think there are any rivals in Shenzhen within 150,000 yuan, and those who have seen Roewe will cost 180,000 yuan. I have seen Zhidou. Although it is 100,000, it is too small and unsafe.

After years of development, BYD is no longer BYD in the f3 era. It is good at grasping the government’s preferential treatment. Buses in Shenzhen are all BYD electric buses, and taxis are also electric e6. Even taxis in the mainland of China are e6. I hope that domestic cars and domestic mobile phones will be strong!

　　[car home Information] (|), a car that has been on the market for half a month but is still worth talking about. After all, before looking up to the ground, it is basically a collection of BYD’s top technology achievements at this stage.

　　Its new technology, "Fast Charge with Two Guns", attracted the comments of friends and business executives: "Cool is cool, but …".

　　Its assisted driving level is in line with the first echelon such as Wei Xiaoli Huawei, which makes Di Fen proud.

　　Its cloud chariot -A was well received, and even the well-known roll king Zhang Chaoyang commented on it as "a roll to the end".

　　　To sum up, today, let’s not talk about rhetoric, but order dry goods, and look at the three core highlights of N7, which are also controversial points-Double gun fast charging, assisted driving and cloud chariot technology,Look at the magic market with 300,000-350,000 volume kings. Is Tengshi N7 playing well?

■ Fast charging of double guns is not a technical problem, but actually a "moral problem"?

　　The media person @ 中中中中 commented on the double-gun fast charge: "This is a philosophical question whether a person can occupy two toilets at once with two bottoms. Very profound. ". I think it is very accurate, so I quoted it directly. The following is a simple popularization of this technology. Let’s see if this evaluation is correct.

　　On the issue of fast charging of pure electric vehicles, major manufacturers have rolled up the high-voltage and high-rate battery solution of "800V+3/4C battery" in unison, and the representative models are G6 and G9 owned by Tucki, which together can achieve the maximum charging time of 5 minutes and battery life of 200 km (data of S4 overcharge of G9 4C models). It is officially claimed that the maximum charging power of 4C battery can reach 480kW, and 3C can also reach 280kW (S4 super-charged pile is required).

"Publicity map of G9"

　　However, BYD just didn’t take the usual road, and put a "double-gun fast charging" technology on Tengshi N7. The "double-gun fast charging" is not a fast charging and a slow charging at the same time, but a fast charging port on the left and right and two fast charging ports at the same time. If you don’t know, you can look at the real shot of car home below.Tengshi N7 has charging ports on the left and right sides of the car body, and one side is a combination of 9-hole fast charging and 7-hole slow charging, just like ordinary new energy vehicles. On the other side is a separate 9-hole fast charge.

"One side of N7 has 9 holes for quick filling"

"One side of N7 has 9-hole fast filling port +7-hole slow filling port"

　　In terms of data, the official claims to charge 300km for 15 minutes, with a maximum power of 230kW for two guns and 150kW for a single gun. Of course, this power also needs the support of the station. You should not fantasize about the power of 150kW on the pile with a calibration of 60kW in the State Grid.

　　The technology of fast charging with two guns is not difficult to realize. The pure electric version of Tengshi D9 is equipped with this technology, but the maximum power that N7 can support has increased.Double-gun fast charging has long been applied in new energy buses, and it is reasonable for BYD to transfer its technology to passenger cars. Weilai’s wet nurse car has also used this technology. It can even plug three guns into a car to replenish electricity, which is very overbearing.

　　The biggest problem of fast charging with two guns may be "morality". This charging mode requires one person to occupy two piles. As we all know, charging piles are scarce resources. Especially on the high-speed holidays, some grumpy brothers have to scold a few words when they look at the ideal or plug-in cars occupy one pile to charge. Excuse me, are the oil in your tank and the engine in the front cabin furnishings? Let them see you take advantage of the situation. You can’t fight, can you?

　　Imagine this scene, because of the length of the charging cable, you may need to park your car between two charging parking spaces, accept the eyes of the car owners, and some good things will ask you a few words, which is simply stinging for me. In addition, there is a soul question-does ——App support double opening? This question is similar to whether a computer can log in to two WeChat, which deserves serious consideration. Of course, at present, some apps such as special calls support double opening, but some don’t. Therefore, it is recommended that you bring a lively friend when charging, which can not only help scan the code, but also charge the car owners with two guns.

　　As for the fast charging power of two guns, the measured data of car home on D9 show that the maximum charging power on a 120kW charging pile is 101.8kW when the power is below 80%, and the power drops to 55kW when the power is above 85%. Measured on N7, when the battery charge is 39%, the power reaches 176.7kW. In addition, some users actually measured that N7 was charged from 20% to 80%, and it took 21 minutes for a single gun and 14 minutes for a double gun.

"Measured data of car home on D9"

"Measured data of car home on N7"

　　We emphasize that the charging speed and power are related to many factors, such as the situation of the station and the battery capacity. Generally, the highest power advertised by the manufacturer cannot be reached, and everyone’s test data is not necessarily the same. Tesla explained this problem clearly, so you can refer to it.　　　

　　

　　To sum up, the advantages and disadvantages of "high-voltage fast charging" and "double-gun fast charging" are theoretically better than that of "double-gun fast charging", but it needs the support of exclusive charging piles and batteries, which is difficult to spread in a short time. For example, Tucki’s S4 is overcharged, and the P7 of the non-800V platform cannot reach that high power; Even the Tesla V3, which is paved more now, cannot be compared with ordinary charging stations in quantity. The fast charging with two guns can make better use of the resources of the station, and can improve the charging speed under the same conditions without modifying the station. In other words, if everyone is in the same State Grid station, the charging speed of two guns together is better than Xiaopeng G9. After all, 800V has nothing to play in this scene.

　　As for some comments on the internet, it is actually a question of "ass decides head", so you can refer to it selectively. For example, Zhao Changjiang of Tengshi once spoke out, "Charging 800V has been fooled by some enterprises in the industry." He said that BYD can achieve a charging peak of more than 700V in 2018, but double-gun fast charging can double the charging efficiency even on a 240V ordinary public charging pile.

　　He Xiaopeng and Li Xiang, who are fast charging the Party, are naturally fans of 800V, and their attitude is shown by the over-charging stations and overwhelming publicity.

　　　Shen Fei, a seemingly neutral Weilai executive who mainly changes electricity, commented that the double-gun fast charging is "in practice, it is not as convenient as expected" based on the car experience of his own wet nurse car.“Being cool is cool, but there are not many occasions that can make you cool.”。 At the same time, he also believes that the charging power is not a problem, and the voltage is not a problem. The key is "whether users have demand or not, and whether enterprises are willing to invest huge sums of money to build super-filled piles".

　　In other words, Tucki and Ideality chose to build their own overcharge station, and Weilai chose to build and replace the power station. BYD didn’t have these ideas, but also hoped that your recharge would be more comfortable and smooth, so it arranged a double-gun quick charge. Everyone is trying their best to serve the owners and help the rapid development of new energy vehicles.

　　At this point, the discussion on "double gun fast charging" has come to an end. Do you think this technology is easy to use? How does it compare with 800V? Welcome to discuss in the comments section.　　　　　　

■ city/high-speed NOA has to wait for OTA?

　　Let’s talk about assisted driving. Now, the new car-making force headed by Wei Xiaoli is crazy with rhythm, that is, about 300,000 electric vehicles must be driven with advanced assisted driving, otherwise it will not be luxurious enough, not smart enough, and it still seems to be behind the times. At present, it has been rolled into the city NOA. And BYD, in these years, has been lacking in this respect.

　　Tengshi N7 "Tengshi Pilot" can be described as making Difen proud.This fusion scheme of laser/millimeter wave/ultrasonic radar+camera+high-precision map can provide high-speed NOA, urban NOA, AVP parking service and full-scene NOA software, which is in line with the current level of head enterprises in theory.

　　　However, Tengshi N7 can’t realize high-speed NOA at present, and it is expected to be realized in Q4., including the ability of point-to-point automatic driving at high speed and handling sudden traffic jams. By March next year, it can realize the functions of avoiding high-speed obstacle cars, driving on ramps with large curvature and parking across floors.NOA driving support in 20 cities is expected to be realized next year.

　　　At present, N7 only has high-speed ACC, lane change with lights, multi-scene automatic parking and so on.. Therefore, if you want to use NOA immediately and experience the happiness of intelligent driving, we suggest choosing Tucki or Aouita. Now they can let you enjoy NOA.

　　As for the actual experience of Tengshi N7 assisted driving, please watch the measured video of car home. To sum up briefly, the basic function is great, and I look forward to higher-level functions!

More exciting videos are all on the car home video platform.

　　　Tengshi Pilot is divided into standard and high-order, which is also very common. Basically, the number of chips and sensors is different. The standard version is equipped with 5 cameras, 5 millimeter waves /12 ultrasonic radars. The chip comes from the horizon, and its functions are the ACC mentioned above. Now people generally call them "L2". The high-end version needs to spend 23,000 yuan (limited time discount) to choose and install, and gave a NVIDIA Orion-X with a computing power of 254TOPS. This chip is also an old friend of everyone and is familiar with it; As well as a camera and two laser radars, the functions include high-speed NOA, urban NOA, HPA memory parking, AVP parking service and so on.According to Zhao Changjiang, 20% of the scheduled car owners chose this set of advanced assisted driving.

　　Regarding this set of assisted driving, because it has not yet landed, everyone is concerned about some theoretical issues, such as the low-priced double horizon journey 3, with a computing power of 10TOPS. At this time, someone jumped out and said, why don’t more than 300,000 cars even give a journey 5? You see, the low match of people’s ideal L7 is Journey 5! Finally, 128TOPS! However, Double Journey 3 has also been put into use in many models, such as Nezha S and Deep Blue SL03. It is no problem to realize the basic functions, and it can be used in other places with some cost savings.

　　There is another melon. The N7 is a very rare vehicle that uses a single NVIDIA Orin-X to realize a series of high-order driving assistance functions (we have reason to suspect that dual Orin-X will be expected). At present, manufacturers that can realize NOA in cities, except for Huawei’s Wenjie and Aouita, all adopt the scheme of two Orin-X, and Weilai ES6 even rolled out four Orin-X, which is not low in cost estimation … So the N7 is in. However, in view of the fact that canoe Zhixing has been able to make a city NOA (no mass production) on a journey 5(128TOPS), I think an Orion-X (254 TOPS) is not impossible. The partner chosen by BYD is Momenta, a supplier who has worked with Zhiji and has rich experience.

　　　At the launch conference of Tengshi N7, BYD also released the "Eye of God" high-order intelligent driving system, which has several innovations, such as the integration of the vehicle’s perception and execution mechanism with software, and a set of hardware, that is, the vehicle-mounted computing platform and the self-developed software vehicle control system BOS.

　　The on-board computing platform is not just the NVIDIA chip, it contains hardware and software. We can watch the video released by BYD. The on-board computing platform is a bit like a circuit board welded by engineering students, which contains hardware and software, and the hardware integrates multiple CPUs and GPUs. There are more layers of software, and BOS is one of them.

More exciting videos are all on the car home video platform.

　　　Having said so much above, I want to emphasize BYD’s self-research ability. At present, automobile manufacturers have different degrees of participation in the self-research of in-vehicle computing platforms. For example, Tesla can develop its own operating system, functional software and even chips. Tucki has realized self-research of various functions, and some manufacturers choose to package suppliers directly. At present, a trend is that as a vehicle manufacturer, it is an ideal path to start self-research from the development of application layer software, then go deep into the self-research of system software architecture, and then develop its own special chip like Tesla to realize self-research of software and hardware. BYD has achieved self-research of operating system, which is still relatively excellent.

　　　Speaking of a thousand words and ten thousand words, the assisted driving thing is still worth seeing in the actual measurement. We also hope that Tengshi will quickly push the advanced driving assistance and prove its strength with the measured data.　　　　

■ Can Yunqi -A compare with the magic carpet of Mercedes-Benz?

　　　If you are a qualified "Difen", you are certainly no stranger to Yunxiao. In April this year, the cloud system was released.It includes four sets of body control systems with different orientations (Yunqi -C, Yunqi -A, Yunqi -P and Yunqi -X).

　　Here we focus on Tengshi N7′ s first ride.Yunnian -A, this is an intelligent air body control system.It is Yunnian -C (Variable Damping Shock Absorber) with air spring, which can change the suspension height, spring stiffness, shock absorber damping and active adjustment of seat wing. We know that the subsequent Yunqi -A supports multi-cavity air springs, and can be monitored by OTA camera and lidar, which is similar to the active sensing function of Mercedes-Benz "magic carpet".

　　In recent years, domestic new energy vehicle companies have been involved in a crazy way, and more than 300,000 vehicles can also enjoy the beauty of air suspension, such as Krypton 001 (Weiback single cavity air suspension), Tucki G9 (Weiback double cavity air suspension) and Zhiji LS7 (mainland single cavity air suspension); Coupled with the efforts of domestic products Kong Hui (ideal supply) and Baolong (supply Tengshi N7), air suspension is almost "flying into the homes of ordinary people", and people are increasingly fond of discussing air suspension.

　　Not long ago, there was a great controversy about whether the ideal L9 suspension could be called "magic carpet". The reason is that some people think that the ideal L9 system can’t scan the road conditions in advance and actively adjust, but passively adjust, which is simply touching the porcelain magic carpet. Some people think that no one has set a standard to say what a magic carpet is. Why can’t an ideal say that it is a magic carpet?Let’s talk here. Do you think N7 can compare with Mercedes-Benz’s "magic carpet" after OTA camera and lidar detection?

"The ideal" magic carpet "hangs in the air"

"Magic carpet technology of Mercedes-Benz"

　　In addition, the single/double-cavity air spring is also the focus of discussion. For example, Tucki G9 uses the double-cavity air suspension from an old foreign supplier, which gives almost the same price at once, but the ideal and momentum of using the domestic single-cavity spring N7 is shocked. Of course, from the known information, the ideal and soaring double-cavity suspension and sensing technology are working overtime.

　　The ideal engineer said well in an interview with the media, "Under the same price range, if you don’t short the spring, the product will not be competitive;" Today, when you use a single-cavity air spring, you see that others use a double cavity. Everyone doesn’t care what the double cavity and the single cavity bring to the car. Even if they are equivalent, they will feel that the double cavity has one more cavity than others, and the performance is good. It is rolled up. " In fact, we consumers should focus on the actual experience rather than focusing on single cavity or double cavity, magic carpet or CDC. The following is the driving experience video of Tengshi N7, which you can refer to or test drive yourself.

More exciting videos are all on the car home video platform.

■ A small egg-6 nm chip

　　　Tengshi N7 conference site, there is also a fun little egg-car chip. This chip is special in the 6nm process. We know that the Qualcomm Snapdragon 8155 used by high-end players at present is 7nm, while the Qualcomm Snapdragon 8295, the next-generation product used for integration, is 5nm. So what is this magical "6nm" process chip?

　　At that time, everyone generally speculated that it was a domestic chip, but later, Zhao Changjiang said in an interview with the media that it was actually a customized Qualcomm chip, which focused on the whole ecology and was suspected to be pluggable, that is, it was very convenient to replace it with a stronger chip later.

　　Tengshi N7 has six screens, which can be driven by this chip. Compared with 8155, its data also has obvious advantages. At present, some car winder manufacturers, such as Ideal, use double 8155. However, for BYD, a conservative car company, Tengshi D9 still uses Qualcomm 7325 when people are crazy about Qualcomm 8155. Such a customized chip can also show sincerity. As for the specific performance and characteristics of the chip, we expect Tengshi to be revealed slowly.

■ Edit comments

　　Tengshi N7 is a car worthy of a special book in terms of significance, products, technology and market. This paper only focuses on its three product points, without much analysis on its significance to BYD and Tengshi, and the future after entering the highly competitive Red Sea market. We also welcome more friends who are interested in this car to actively participate in the discussion in the comment area. (Text/car home Xing Yueyang)

In recent days, Huawei’s new overcharge station in Bantian, Shenzhen has been exposed. There are 8 super-filled piles in this site, which are only used for Huawei’s internal testing at present. The nameplate of super-filled pile is very scary, which impressively says that the output voltage range is 200-1000V, the maximum output current is 600A, and the maximum output power is 600kW. Moreover, Huawei didn’t "steal and play tricks" like some new forces. It used two guns to "make up" 600kW, and adopted a single-pile single-gun design.

When competitors are still rolling 800V voltage and 360kW charging power, Huawei directly pulled to 1000V and 600kW, which can be said to increase the power of over-filled piles by one dimension.

How does Huawei achieve greater charging power by leaps and bounds? What does the appearance of 600kW over-filled pile mean? Let the Kung Fu car show you around.

(1) 100 degrees in 10 minutes, more than twice as fast as Tesla V3?

First of all, we have to figure out what is the concept of 600kW overcharge. Let’s just say that ordinary household slow charging is generally 7kW, and Huawei’s overcharging speed is nearly 100 times that of household slow charging. The power of State Grid charging piles is generally 40 ~ 60 kW, and 600KW is more than ten times that.

Tesla V3, which is talked about by fans, is overcharged, with a maximum power of 250kW, which allows Model 3 to travel 250 kilometers in 15 minutes. The charging speed of Huawei’s 600kW overcharge is more than twice that of V3. Theoretically, it can charge 100 kWh in 10 minutes, and it can fill the Qian Shan Cui of Han EV with a battery life of more than 700 kilometers in a little more than 10 minutes.

Since the advantage of overcharge is so great? Then why don’t other car companies do the 600kW overcharge like Huawei? Of course, I don’t want to do it, but I can’t do it.

To increase the charging power, it is necessary to increase the charging voltage or current. Increasing the voltage will make the arc problem more serious, and at the same time, higher requirements are put forward for the performance of high voltage DC relay, such as withstand voltage grade and current carrying capacity. Increasing the current will lead to thicker cables and greater heat loss, and even female drivers may not be able to carry charging piles.

The technical difficulty is too high, which is also the reason why the ultra-high power overcharge can not be popularized.

Judging from the current situation, Huawei, as a technical madman, seems to have initially found the answer. According to Huawei official website’s introduction, this new type of over-charged pile is called "FusionCharge DC Super Fast Charging Terminal", and a special liquid cooling structure is introduced to solve the problem of excessive heating under high current, and at the same time, the cable weight is reduced by 50%, which can be easily controlled by ordinary drivers.

In terms of high voltage realization, Huawei has developed a set of "kilovolt high voltage" full-stack power domain solution, which not only includes electric drive boosting and high voltage thermal management at the automobile end, but also includes ultra-high voltage realization at the charging pile end. After all, Huawei itself started as a power electronic device, and it is also an authority in the field of inverter servo. It can be said that it is a great advantage to make super-filled piles.

Other car companies are miserable. They rely more on suppliers, but suppliers are less likely to vigorously develop new technologies to impact their existing businesses. In this way, Huawei’s 600kW may be super-charged and exclusive for a long time.

(2) Ask M9 to take the lead, and Aouita and Polar Fox will have soup?

Now that the 600kW over-filled pile has come out? So which cars can be used? At present, the polar fox Alpha S and Aouita 11, which adopt Huawei HI technology, should bear the brunt.

According to the previous news, the Extreme Fox Alpha S Huawei HI Edition is equipped with an 800V high-voltage fast charging platform and a 480kW low-temperature pulse speed heating function, which can enter the state at the moment when the charging gun is inserted. Because Aouita 11 is compatible with the design of single motor, it adopts a 750V high-voltage fast charging platform, which can also charge for 10 minutes and increase the battery life by 200km.

These two models are the highest-end models of Huawei, but strictly speaking, they can’t play the full strength of 600kW overcharge, which is determined by the electrification platform of the model.

Not surprisingly, the first model to take the 1000V high-voltage platform will be Huawei’s flagship SUV M9. With the 600kW overcharge blessing, its recharge ability is naturally no longer worrying.

For the first time, the M9 will be equipped with a complete Huawei advanced assisted driving solution, which is the advanced version of the set on Huawei HI Edition of Extreme Fox Alpha S.. With the help of a new generation of lidar and intelligent driving chips, the computing power and perception ability have been greatly improved, and with the help of more mature algorithms, there is no doubt that it will stabilize the first echelon of intelligent driving in China.

The new car will also be pre-installed with HarmonyOS OS3 system, which can realize the functions of super desktop, PC dual-screen collaboration, adaptive adjustment of HUD height, intelligent car search and so on. The HUD can be adjusted adaptively according to the driver’s sitting posture, the PC dual-screen cooperation can make the new car "mobile office" in seconds, and even the Tik Tok can be controlled through the steering wheel, and the time dynamic wallpaper will change actively according to the climate and time.

In short, if you are interested in smart technology after all, Huawei’s new flagship SUV will never be disappointing. It is the ceiling.

(3) The journey and power exchange are all gone, and Huawei is playing with the bottom of the pot?

The greater significance of Huawei’s mass production of 600kW overcharge may lie in the impact on other "transition" routes. It has to be said that although the penetration rate of new energy vehicles in China has exceeded 30%, the growth rate of pure electric vehicles is not as good as that of plug-in hybrid and extended-range electric vehicles, and many car companies are eager to change the power mode.

The most critical point is the "mileage anxiety" of electric vehicles. The battery life of a new generation of electric vehicles is not low. Take the deep blue SL03 as an example. For less than 200,000 yuan, you can buy a pure electric version with a battery life of 705km. Even if the battery life is discounted under special circumstances, it is not a problem to run 600km.

Can a fuel truck run 600km with a tank of oil? In fact, it is also very mysterious. Take "Divine Car" Sylphy as an example, its fuel tank volume is 47L, and the fuel consumption in urban areas is about 7.5L/100km, so the battery life will exceed 600km. But this is one of the most fuel-efficient A-class family cars. In fact, most of the best-selling cars and SUVs can only run about 550km per tank of oil.

In other words, the battery life of electric vehicles is actually not weak, and the real difficulty lies in replenishing energy. On the one hand, charging stations are not as ubiquitous as gas stations, on the other hand, the charging speed can’t keep up. One car often occupies the charging pile for more than an hour, and other cars can only stare.

Changing electricity can solve this problem to a certain extent, but at the cost of higher requirements for battery design and greater investment in infrastructure, just changing the battery reserve of the power station is not a small expense.

Distance can also solve some problems. Usually, electricity is used in urban areas, and oil is used in high-speed situations, so you don’t have to worry about running out of batteries. However, the two systems of oil and electricity take up a lot of space and cost in parallel, and most people will choose to use electricity mainly (after all, electricity is cheap), so the pressure on the battery will be greater and the frequency of charging will increase greatly.

Comparatively speaking, ultra-high power overcharge may be a better answer. The charging sales volume of Huawei’s 600kW fast charging station is more than ten times that of ordinary State Grid charging station and more than twice that of Tesla V3 fast charging station, which means it can accommodate more electric vehicles. At the same time, it can replenish 400km in 5 minutes, and consumers’ confidence will be more sufficient, and their anxiety will be greatly reduced.

From this perspective, Huawei has actually come to the bottom of the pot. It seems that you are engaged in technical climbing inadvertently, but actually you are indirectly attacking your opponent.

(4) Kung Fu is angry

Finally, many people think that 600kW over-filled piles can only be used by specific vehicles, but this is not the case. Charging piles can be "backwards compatibility", whether it is 250kW, 350kW, 450kW overcharge or 600kW overcharge, they can be synchronized and compatible.

In other words, don’t worry about Huawei’s overcharge. The biggest suspense now is what advantages Huawei can achieve through this technology.

I have to say that after Huawei entered the market, it added more scientific and technological ideas to the automobile industry.

In the "Children’s Companion Home" in Nanbian Village, Gongfang Town, Le ‘an County, Jiangxi Province, the "Children’s Companion Mom" took the children to play with toys. Xinhua news agency

　　[Talking about health]

　　Magnetic buckyball, jelly-like crystal mud, luminous balloon … … These "online celebrity" toys, which have sprung up in recent years, are likely to become "sharp weapons" to hurt children. According to media reports, in the past summer vacation, many children in Guangdong, Hubei, Xinjiang and other places suffered gastrointestinal injuries due to swallowing buckyball by mistake, and even needed surgery. What other children’s toys need attention? Where are their security risks? Our reporter sorted out the consumption tips issued by the Defective Product Management Center of the State Administration of Market Supervision, selected some children’s toys that are currently popular in the market but have hidden dangers, analyzed their safety hazards, and called on the whole society to pay more attention to the safety of children’s toys.

　　My two-year-old daughter often has a stomachache recently. Her parents thought it was a gastrointestinal problem. As a result, she was sent to the hospital for examination and found that there were four intestinal perforations in her body. Parents are both afraid and puzzled. Why do children have intestinal perforation? It turned out that there was a magnetic bead toy named "buckyball" at home that was swallowed by the girl by mistake, and the hospital finally took the magnetic beads out of the girl through emergency surgery … … This is a recent report in the media. This hospital has treated 7 children who swallowed buckyball by mistake in the last month or so.

　　This is not the only report that children’s toys hurt people, and buckyball is not the only children’s toys that hurt people. Magnetic buckyball, jelly-like crystal mud, luminous balloon … … These "online celebrity" toys, which are novel or fun, are ignited by online social platforms, and often become dangerous goods that hurt children.

　　The Defective Product Management Center of the State Administration of Market Supervision is responsible for the defect investigation and public opinion monitoring of all kinds of products on the market, and issues consumption tips to recall the defective products. The reporter found that children-related products, including toys, accounted for almost two-thirds of the consumption tips released by official website. The Quality Development Bureau of the General Administration of Market Supervision introduced at the theme activity of children’s products safety education on June 1st this year that since 2008, China has carried out 1,189 recalls of children’s products, accounting for 49.6% of the recalls of consumer goods, involving nearly 6 million pieces, and one recall of children’s products is every two recalls of consumer goods on average.

　　These toys and other children’s products with defects in design or quality, in order to attract children, excessively pursue fun and ignore safety. In particular, the security risks of the novel toys that attract attention on the Internet and have the "online celebrity" effect cannot be ignored.

　　Buckyball and the small magnetic beads of the magnet pen, "wearing the intestines and breaking the stomach"

　　Buckyball is a kind of magnetic beads with a diameter of about 5mm. Many buckyball can be combined into various shapes at will with the help of magnetic force, which has been advertised by merchants as "educational toys" and is very popular with children and parents. There is also a magnet pen with a similar design with buckyball, which is also a new online celebrity product in recent years. In addition to the normal writing function, this pen is inlaid with magnets at both ends, and with matching steel balls, it can realize a variety of combined games by magnetic force. However, buckyball and the magnetic pen, which are fun and creative products, actually have great security risks.

　　The Defective Product Management Center of the General Administration of Market Supervision once published a case in which a 13-year-old boy in Guizhou sucked a magnet into his mouth while playing with a magnet pen in class, and then used another magnet to attract the magnet in his mouth. As a result, the two magnets successively entered the abdomen along the esophagus. When I went to the hospital for examination, I found that the two magnets were attracted tightly across the stomach muscle layer, and a 0.1 cm perforation was chiseled.

　　"There are not a few cases of such magnet injuries, and most of them are concentrated in children aged 1 to 10." The Defective Product Management Center of the General Administration of Market Supervision pointed out in the consumption tips that small magnetic parts such as magnetic beads are more likely to be swallowed by children by mistake, and if they enter the trachea, they will cause the danger of suffocation; If it enters the digestive tract, it will cause vomiting and abdominal pain, and it will lead to gastrointestinal damage; Especially when two or more magnets are swallowed, the magnets will adsorb each other through the gastrointestinal wall in the digestive system, and continue to generate pressure, which may cause gastrointestinal perforation or intestinal obstruction, which may be life-threatening in severe cases. In general, these small magnetic parts can only be removed by surgery, which will cause permanent damage to children’s digestive system.

　　The Defective Product Management Center of the General Administration of Market Supervision reminds that there are many kinds of magnet pens sold in the market, but most of them are three-no products. Not only do they have no factory name, address and product certificate, but also there are no warning instructions on the pen body and packaging, so the safety cannot be effectively guaranteed. It is recommended not to buy such products.

　　Borax poisoning of "mud" toys such as crystal mud should not be underestimated.

　　The charm of magnet toys lies in the creative experience of combination play, and similar to it, "mud" toys also have such functions. In recent years, all kinds of soft, sticky, jelly-like "mud" toys have become popular around campus and online platforms. They have different names, such as Crystal Mud, slime, Bubble Mud, Cotton Mud, Poke Mud and Snowflake Mud, but they have common characteristics — — Colorful, soft to the touch, can change various shapes, and can also be used to blow bubbles, draw pictures, etc., which is deeply loved by children.

　　However, they are not real mud, but are made of many chemicals. These "mud" contain a substance that may be harmful to health — — Borax.

　　According to the introduction of the Defective Product Management Center of the General Administration of Market Supervision, polyvinyl alcohol, a polymer material dissolved in water, reacts with borax (also known as coagulant aid), and the dissolved polyvinyl alcohol is pulled together by the anions of borax to form a hydrogel with a network structure; On this basis, hand sanitizer, emulsion, pigment, beads, clay, etc. are added to make various "mud" toys such as crystal mud.

　　These "mud" toys are brightly colored, similar to jelly, and usually have their own straws, which can blow bubbles nominally. When children blow bubbles with straws, the product comes into close contact with the mouth, which may lead to the risk of borax poisoning. The Defective Product Management Center of the General Administration of Market Supervision explained that borax is extremely harmful to human health. Excessive intake in a short period of time will cause nausea, vomiting, depression, convulsions, skin flushing, circulatory failure and other symptoms. Excessive intake for a long time will lead to cumulative poisoning of multiple organs, causing damage to organs such as liver, kidney, brain and lung. The toxic dose of borax is 1 to 3 grams for adults, 15 to 20 grams for adults and 5 grams for children.

　　At present, borax is prohibited as a food additive in many countries, and the intake of boron is limited. The national standard (GB5749-2006) of Hygienic Standard for Drinking Water in China stipulates that the limit of boron in drinking water is 0.5 mg/L. The EU’s requirement for boron content in toys made of liquid, pigment, jelly and other materials is limited to 300mg/kg. The Defective Product Management Center of the General Administration of Market Supervision has tested 10 kinds of finished crystal mud products randomly purchased, and found that the boron content of 8 kinds of products exceeded 300mg/kg, and the highest one reached 1336mg/kg, far exceeding the safety limit of boron content in various countries. Once children eat by mistake when blowing bubbles with these crystal mud, there may be a danger of borax poisoning.

　　Perhaps it is realized that this toy with borax directly added is easy to be found, and some merchants have introduced the so-called "non-toxic crystal mud" products, adding some daily chemical products to the glue containing polyvinyl alcohol instead of borax, such as washing powder, laundry detergent, shower gel, guar gum and so on. "This is actually very confusing, because these daily chemical products actually contain borax ingredients, and children also have the safety hazard of eating poisoning during playing." The Defective Product Management Center of the General Administration of Market Supervision pointed out in the consumption tips that any toy containing borax does not meet the requirements of our country.

　　The Defective Product Management Center of the General Administration of Market Supervision also specially reminded that homemade "mud" toys are more dangerous than finished products, and children will be directly exposed to large doses of borax and other chemical ingredients during play. Skin exposure to these chemicals for a long time is likely to cause chemical burns, allergies or cumulative poisoning; If children abuse the preparation container during play, such as drinking water from a glass filled with borax, or not washing their hands in time after play, it is easy to eat borax or other chemical ingredients by mistake, leading to the danger of poisoning.

　　For toys such as crystal mud, especially homemade "mud" toys, the advice given by the Defective Product Management Center of the General Administration of Market Supervision is: Don’t buy!

　　Online celebrity balloons will glow or explode.

　　On this summer night, you can often see sparkling balloons with colorful light in squares or parks, which are very popular with children. This kind of balloon first attracted attention on online social media, and was called online celebrity balloon by many people. However, although the online celebrity balloon is beautiful, it has hidden dangers. According to media reports, there was a balloon explosion in online celebrity somewhere in Jiangsu province, and four people were hospitalized with different degrees of burns.

　　How can a balloon explode? How serious is the harm?

　　According to the Defective Product Management Center of the General Administration of Market Supervision, this luminous balloon is mainly composed of transparent balloons, multicolored light strips and battery boxes, and its structure is very simple. A string of thin multicolored LED strip is wrapped around the surface of the transparent balloon, and a small battery box is tied to the tail end of the traction rope. The battery is placed in a plastic box, and the power supply is directly connected to the light strip, and the light can be emitted when the switch is turned on.

　　The balloon itself is a pressure vessel, and with this design and construction, the safety risk is higher. Testing by the Defective Product Management Center of the General Administration of Market Supervision found that balloons in online celebrity are mostly made of plastic, and once they come into contact with high-temperature heat sources (such as stoves) or open flames (such as lighters), balloons may explode. On the one hand, the surface temperature of the melted plastic is very high at high temperature, and the plastic liquid dripped from the melted plastic will cause serious burns and scalds if it sticks to human skin. On the other hand, balloon deflagration will produce irritating toxic gas, which may cause burns and other injuries to human respiratory tract. In addition, due to the bare wires, sparks may be generated during use, which may cause the balloon to explode.

　　Some experts pointed out that the gas inside the online celebrity balloon may also become a safety hazard. For safety reasons, balloons are generally filled with inert gases such as helium, and hydrogen has long been prohibited from being used to inflate balloons because of its flammability and explosiveness. However, because hydrogen is cheaper than helium, some unscrupulous merchants may still use hydrogen to inflate online celebrity balloons. In a online celebrity balloon explosion reported by the media, experts pointed out after analysis that "judging from the power of the balloon explosion described by the injured, the balloon they bought is likely to pass off hydrogen as helium".

　　The Defective Product Management Center of the General Administration of Market Supervision reminds that children should play such balloons under the care of their parents; Stay away from fire sources, heat sources and sharp objects when playing with balloons, and don’t use lighters to burn the traction line of balloons; It is best not to buy such balloons when the weather is very hot, because high temperature weather is more likely to cause balloon explosion; Don’t take a balloon in a car, subway, elevator, etc. Once an explosion occurs, the impact of a closed space will be very great.

　　Laser pen can cause permanent damage to eyes. Don’t play with children.

　　The light is dazzling and dangerous. Online celebrity balloon, laser pointer.

　　I don’t know when, the laser pointer used as an indicator in classroom teaching, conference explanation and other places has become a toy for many children and a dangerous toy. As a result, there have been many reports in the media: "When a laser pointer shines, the eyes of a 7-year-old boy can’t see", "When an 8-year-old boy plays with a laser pointer, his eyes are permanently damaged", and "The sampling tests of online shopping for children’s laser pens all exceed the standard, and the harmful visual damage is irreversible" … … According to the Defective Product Management Center of the General Administration of Market Supervision, according to the product injury monitoring and network public opinion monitoring, injury accidents involving laser pens have occurred frequently in recent years.

　　Laser pointer, also called laser pointer, is a portable device that uses battery and laser module (light emitting diode) to emit visible light beam, which is mainly used to accurately indicate the target at a long distance. In China, according to the degree of radiation hazard from low to high, laser products are divided into the following grades: class 1, class 1M, class 2, class 2M, class 3R, class 3B and class 4. The Defective Product Management Center of the General Administration of Market Supervision pointed out that if laser products are not used properly, it will cause serious damage to human body, especially for products of 3R and above. Laser pens sold on the Internet usually have very high power and can even light matches, cigarettes, clothes and so on.

　　The power is so high that it can ignite clothes. If you irradiate your eyes, the consequences can be imagined. According to experts, due to the characteristics of eye imaging, when the laser passes through the eye, it will be focused on a very small point on the retina, which will lead to an instantaneous increase in temperature and destroy the photosensitive cells of the retina. If the laser energy is strong enough, it will cause permanent damage without causing blink reflex (usually less than 1 second). It should be noted that low-power laser may also cause harm to eyes, and some high-intensity lasers still do great harm to eyes even after scattering from the surface of objects. Children in the developmental stage have delicate eye tissues and thin retinas, which are more vulnerable to injury.

　　Laser pointer will not only cause direct damage to eyes, but also interfere with normal vision, which may lead to other accidents. For example, illuminating vehicles, airplanes, etc. with a laser pen may affect the normal vision of drivers and pilots and cause serious accidents.

　　Of course, the laser pen is not unusable, but should be used scientifically and safely. According to different use occasions and users, the laser pen with corresponding radiation level should be carefully selected. The Defective Product Management Center of the General Administration of Market Supervision reminds that laser pen products can be used in situations such as classroom teaching and conference explanation. The laser in children’s toys should meet the requirements of Class 1 laser radiation power limit.

　　"The laser pens sold as toys in the market are mostly higher than this limit, which has great security risks and cannot be bought and played for children." The defective product management center of the General Administration of Market Supervision stressed.
