[YesAuto New Energy] Earlier this year, I went to the Tesla V3 super charging station in Jinqiao, Shanghai to experience the first batch of V3 superchargers built in China, and made a detailed comparison with the V2 superchargers. At that time, the measured maximum charging power of the former up to 233kW impressed me, and what surprised me more was the compact and lightweight design of the V3 supercharger charging gun.

After more than half a year, Tesla finally began to expand the scale of construction of the V3 super charging station. In just two weeks, two buildings were built in Guangzhou and Beijing. So what is the difference between the new V3 supercharger station and the old one? How do Tesla owners comment on the V3 supercharger? Is the current V3 overcharge station hard to find? With these questions in mind, we recently visited the Tesla Supercharger station in the China Central Place Shopping Center in Beijing.

◆What is a V3 supercharged pile?

In early March 2019, Tesla officially released its third-generation super charging pile at its California headquarters. According to the official statement, this generation of supercharger is an overcharge method that uses a new architecture. The maximum charging power can reach 250kW. Compared with the previous generation of V2 supercharger (the vehicle battery is not preheated), the charging speed can be increased by 50%. (Cooperate with the on-the-go charging function to warm up the battery).

In contrast, the charging power of the V2 supercharger can only reach up to 120kW. Because of the one-to-two format, each distribution station can only provide 150kW of maximum charging power. Therefore, when the same group of two V2 charging piles have high charging requirements, the system needs to dynamically allocate the 150kW power. The logic of the allocation is related to the charging sequence of the vehicle and the battery status.

Some insiders speculate that, in addition to being affected by domestic power distribution conditions, the configuration of Tesla's domestic V3 overcharge station is also somewhat different from that of foreign countries. It is understood that foreign V3 super charging stations are also equipped with Tesla’s energy storage product Powerpack and solar energy collection devices. When the charging pile is idle, the energy storage products will obtain electricity from the solar energy collection device and the grid, and when there are multiple cars charging When the burden on the grid is too large, Powerpack will provide additional electric energy to meet the rapid replenishment needs of the vehicle and make up for the insufficient power supply of the grid.

However, in the domestic V3 supercharge station, we seem to have not seen the powerpack. It is speculated that Tesla has not introduced the Powerpack into the country, so the V3 supercharge station cannot be equipped with this “artifact”. Of course, this is just our guess. If this is the case, we look forward to Tesla's subsequent introduction of Powerpack to improve the situation that domestic V3 overcharge stations still need to be diverted.

◆Is the charging speed improved significantly?

Next, I believe everyone is more concerned about how fast the charging speed of the V3 super charging pile is. In the charging experience content of the V3 super charging pile at the beginning of this year, we compared the charging speed with the V2 super charging pile in detail for everyone. Interested netizens can go to see the detailed test process (portal: 10 minutes of charging 42 % Tesla V3 super charging pile actual test) , and in this article, I will tell you the results directly.

After actual testing on the Model 3 long-endurance all-wheel-drive version (imported), we found that although the maximum charging power of the V3 supercharger is twice as high as that of the V2 supercharger, the maximum charging power is only It will stay for a short time, and then it will begin to fall. In the second half of charging, there is almost no difference between the charging speeds of the two generations of piles. Therefore, the actual charging time mainly opens the gap in the first half, and the difference in total charging time will not be so great.

◆The difference in appearance between V3 and V2

So in addition to charging faster, what is the difference between the appearance of the V3 supercharger and the previous generation? In fact, the exterior design of the V3 supercharger has not changed completely. Even during my visit, many unsuspecting Tesla owners could not tell which is the V3 supercharger. But if you look closely, the two are still easy to distinguish.

Comparison of the lifting weight of the charging gun and the measured wire diameter
Charging pile type Lifting weight (kg) Diameter of charging cable (mm)
V3 super charging pile 2.325 23.87
V2 super charging pile 2.965 36.33
State Grid 120kW charging pile 4.230 38.82
Tabulation: Autohome New Energy Channel

Relying on the new liquid cooling technology and user-friendly design, the charging operation of the V3 supercharger is significantly easier than that of the older generation. As for the charging gun plugging experience of the domestic fast charging pile, it is even more unfriendly, not to mention it is very heavy, and the process of plugging into the charging port is also very laborious, even if it is an adult male, it requires full operation with both hands.

◆Different Tesla models have different compatibility with V3 supercharger?

According to the current Tesla official statement, the only models that are compatible with the 250kW peak power of the V3 supercharger are the long-life versions of Model 3 and Model Y, because they use Tesla’s latest 21700 battery system, and the battery pack is equipped with The latest thermal management technology.

The Model S and Model X, which are positioned as flagships, use the older 18650 battery system and the older generation of thermal management technology. The current maximum charging power that can be achieved on the V3 overcharge is only 200kW. This is still the performance of the 2019 models launched last year after the battery system is optimized, and the previous models can't even reach the charging power of 200kW.

The maximum charging power that different Tesla models can obtain in the V3 supercharger (official data)
Model version Maximum charging power (kW)
Model 3 Long endurance all-wheel drive version, long endurance rear-drive version, Performance high-performance all-wheel drive version 250
Standard endurance rear drive upgraded version 170
Model Y (not yet delivered domestically) Long battery life all-wheel drive version (overseas), Performance high-performance all-wheel drive version (overseas) 250
Model X 2019 model (Raven version) and later versions 200
Model S 2019 model (Raven version) and later versions 200
Note: The compatibility of other unspecified versions is currently unknown.

In addition, compared with the imported version, the domestic version of Model 3 has different battery suppliers. The supplier of the imported version is Panasonic, and the current supplier of the domestic version is LG Chem, and the Ningde era will be introduced in the future. Carrying batteries from different suppliers will also have an impact on the charging performance of the V3 supercharger. According to the current comparison on the Internet, the charging speed of the domestic Model 3 is slightly slower than that of the imported version.

◆Can the future construction of V3 supercharge stations keep up?

As of April 2020, Tesla has built more than 2500 super charging piles in China, covering only 90% of the domestic population. According to the official plan, when 2020 ends, this number will exceed 4000, which will include a large number of V3 overcharged piles, but the official number has not been announced.

However, even if Tesla is rapidly building its own charging infrastructure, we should also see the current domestic sales of Tesla models represented by the domestic Model 3 are increasing sharply. Nowadays, the monthly sales volume of only Model 3 in China exceeds 10,000, so the shortage of charging piles is still a serious problem for Tesla.

Above, we have a more comprehensive understanding of the V3 supercharged pile from the four aspects of technical principles, actual performance, appearance differences and compatibility. It can be seen that although the V3 supercharged pile still has a diversion situation, the charging experience has been greatly improved compared with the previous generation products, and even the domestic mainstream level. So for Tesla owners, do they agree with this experience improvement? Before I did this visit, I thought the answer must be yes, but the final result was completely unexpected.

◆How is the operation of the V3 supercharge station now?

After five o'clock in the afternoon, I entered the evening rush hour in Beijing. I came to the open-air parking lot in front of the China Central Place Shopping Center. Except for Tesla and Porsche Taycan, no other vehicles were allowed to enter. When you come to the parking lot, you can see a row of charging parking spaces specially designed for Tesla vehicles. Among them, 20 charging parking spaces are placed behind V2 super charging piles, and behind the six parking spaces near the entrance area, they are only recently. The Tesla V3 super charging pile has just been installed and put into operation.

Question 1: What version of your model?

Model X owner: Model X long battery life version, bought early last year.

Question 2: This is the first time you have used the V3 Super Charging Pile? How was the experience?

Model X owner: For the first time, I started charging from 18% just now, and the maximum can reach 100kW, which is slightly faster than V2, because V2 has a shunt, and usually can only reach 60-70kW.

Question 3: Do you usually charge at home or publicly?

Model X owners: Public charging is the main thing, because the homes with conditions for charging don't live very much, so the main thing is to go to the Tesla overcharge station.

Question 4: Will you take ownership of a self-operated charging system as your basis for buying a car?

Model X owner: Yes.

Question 5: Do you think the charging experience of electric vehicles is far worse than the refueling experience of fuel vehicles?

Model X owner: I didn't think it was because this place is more convenient. Shopping, shopping, and eating time passed, (charging) one hour is fine.

Question 1: What version of your model?

Model 3 owner: Model 3 imported long-life rear-wheel drive version, a car that was only mentioned in June last year.

Question 2: This is the first time you have used the V3 Super Charging Pile? How was the experience?

Model 3 owner: I use the V3 charging station for the first time, and it feels so fast, faster than the online reviews, but I am still quite worried about the damage to the battery.

Question 3: Do you usually charge at home or publicly?

Model 3 owners: Public charging is the main option, because there are no charging conditions at home.

Question 4: Will you take ownership of a self-operated charging system as your basis for buying a car?

Model 3 owner: Yes, I mainly use Tesla's. State Grid's is not very useful because it is a bit biased.

Question 5: Do you think the charging experience of electric vehicles is far worse than the refueling experience of fuel vehicles?

Model 3 owner: No difference. I usually drive in the city because I am not particularly busy. I usually charge the battery in 30 or 40 minutes, play with the phone, and the time for playing games is over. You can also go shopping in the mall. ; As for running long distances, you have to take a break and eat something. At this time, there is no delay in charging, so the impact is not great.

Question 1: What version of your model?

Model 3 female owner: Model 3 standard endurance rear-drive upgraded version, the car just mentioned.

Question 2: This is the first time you have used the V3 Super Charging Pile? How was the experience?

Model 3 female car owner: What is a V3 supercharger? I don't understand. (The editor then gave a brief introduction, but the owner did not express his attitude)

Question 3: Do you usually charge at home or publicly?

Model 3 female car owners: Public charging is the main option, and the parking spaces at home are not fixed and cannot be installed.

Question 4: Will you take ownership of a self-operated charging system as your basis for buying a car?

Model 3 female owner: Yes, when I bought a car, I also considered Mercedes-Benz EQC, but because the charging station has not yet been built, I chose Tesla in the end.

Question 5: Do you think the charging experience of electric vehicles is far worse than the refueling experience of fuel vehicles?

Model 3 female car owner: To be honest, I don't care about this problem. Put the car here and go to the mall for two or three hours. You see, I want to eat now. But it seems that if you don’t drive the car away, there will be an overtime occupancy fee. This is so expensive, 6 yuan per minute. I hope it can charge more slowly.

After interviewing the above three car owners, I waited for a while, but no car came here to charge, but there were cars coming to charge in the parking area of the V2 charging pile next to it. Then I changed my strategy and interviewed a car owner who just came to charge the V2 supercharger. First of all, I first came to a Model S that was charging. From the blue license plate of this car, it can be concluded that this is a car that has been delivered for a long time. (Because a few years ago, the new energy vehicles sold in Beijing could only be listed with blue cards, now they have green cards)

Question 1: What version of your model?

Model S owner: Model S (75D standard battery life version).

Question 2: Have you understood and used the V3 super charging pile?

Model S owner: No, I don’t know. (The author then introduced her to the fast charging characteristics of the V3 supercharger. She expressed interest, but when she told her that the old Model S could not enjoy such high charging power, she became a bit regretful.)

Question 3: Do you usually charge at home or publicly?

Model S owner: I only use public charging stations.

Question 4: Will you take ownership of a self-operated charging system as your basis for buying a car?

Model S owners: Yes, like other electric cars, you can only charge them in a relatively biased place. I definitely don't accept this. I hope they (Tesla) will build a little more, all of them are built next to the mall.

Question 5: Do you think the charging experience of electric vehicles is far worse than the refueling experience of fuel vehicles?

Model S owner: I didn't think it, but it actually takes an hour in the car to look at the phone or go shopping in the mall. I don't think it is a problem. However, its biggest problem is that it has overtime occupancy fees, which have not been charged before (Editor’s note: Tesla also had an overtime occupancy fee policy before, but it did not actually charge fees. However, since this year, it has been charged, and the owner’s previous fees have not been charged. Cleared) Suddenly one day, I was told to pay overtime occupancy fees, and then charged me 1.7…

First of all, I thought that the charging problem of electric vehicles was a shortcoming for the owners to complain about, but after interviews, I found that almost most Tesla owners have a high degree of acceptance. And most of the reasons they can accept are that they can spend a while alone in their busy schedule, play mobile phones, games, or go shopping in the mall or have a meal during the charging time. This time is enough to fill their car with enough power, so it is not Caused them too much trouble.

It is worth mentioning that when I interviewed Tesla owners in the United States, I also encountered a similar situation (article portal: Serious polarization on the development of new energy vehicles in US auto companies) . This made me realize that the characteristics of the use of electric vehicles are changing people's lifestyles, and we cannot simply look at the experience of electric vehicles based on the experience of fuel vehicles.

Another point is that unlike the extremely high media attention, Tesla owners’ expectations for the V3 supercharger are not as high as we thought, and they have not even charged their car closer to the entrance of the mall. Parking spaces are important. This is mainly because the relatively slow charging time of the V2 supercharger allows them to have more free time to go shopping, eat or simply take a rest.

However, I believe that faster charging time is still needed by many people. In some scenarios, people need to quickly replenish the battery, and in some scenarios, users do not need to charge quickly. Therefore, the use needs of V3 and V2 superchargers are actually Some differences. Thinking carefully, when many domestic manufacturers are still using battery life and performance as the capital to compete with Tesla models, they have not realized that consumers may care more. There is a charging condition closer to the mall. ….. (Picture/Text Hu Yongbin, Auto Home)
