How many kilometers does a 5-minute charge last to win?
The two key problems that plague pure electric vehicles are range and charging. Compared with the two items, I think the problem of charging is greater.
Nowadays, the pure electric vehicle platform, the integration technology of the battery pack has been very strong, 140 degrees of electric energy for 1000 kilometers to improve the support of the battery can still be placed, the endurance is not enough can be made up by stacking battery pack capacity, or it can be avoided by planning the travel path.

But the slow charging speed is still an unsolvable problem for the current pure electric vehicles, especially in the event of holidays, high-speed charging piles always have to queue up, even if you have a double gun fast charge, it is waiting for a ship at the airport.
If one day charging can be as fast as refueling, then for consumers, there may be no pure electric vehicle range anxiety.
Even if a small pure electric vehicle with a range of 200km, if it lasts 500 kilometers in 5 minutes of charging, then the manufacturer does not have to roll the range on the pure electric vehicle, and the battery pack capacity is reduced for consumers, and the cost of buying a car is also low.
Of course, some people will say that the power exchange strategy can be used to power up like refueling, but it must be known that the service capacity of the power exchange station is also limited due to the battery charging capacity.
Taking the three-generation NIO replacement station as an example, although the power exchange time of the third-generation replacement station is shortened by 20% compared with the previous generation, the number of battery positions has increased to 21, and the daily service number can reach 408 times, the daily service capacity is not high compared to the gas station with rapid replenishment.
This is why many industry experts believe that layout overcharging will be more important than battery replacement.
The battery of the exchange station itself is also to be charged, and improving the single-day service capacity of the replacement station is inseparable from improving the energy replenishment speed of a single battery, which is the same as the hotel's pursuit of the turnover rate in order to make better money.
Otherwise, only a super-large substation can be built, and the frequency of service is increased by the number of battery reserves, but this will obviously increase the operating costs of the substation, and will have an impact on the laying density of the substation.
In addition, supercharging has another advantage is "not picking the car", although the supercharging pile wants to fully exert its strength, it needs the end of the high-voltage platform and the pile end to cooperate, but it does not mean that the model of the non-high-voltage platform is not possible.
Even a certain brand of supercharging can be fully developed externally and become a public shared resource for new energy vehicles. On the contrary, the standardization of power exchange is more troublesome, and it is difficult for different brands and levels of products to enjoy the same power station, which is also a waste of resources to some extent.
What's more, the construction and operation and maintenance costs of a single supercharging station itself are much lower than those of the replacement station, and the supercharging station can quickly spread the volume to improve the experience of pure electric vehicles.
Having said all this, the core idea is very simple: the solution to the rapid replenishment of pure electric vehicles in the consumer market and the anxiety of no cruising range depends on overcharging, and only technological progress to improve the charging rate is king, rather than using means such as battery replacement to avoid charging problems.
So the question is, how fast is the current overcharging speed of pure electric vehicles? A long time ago, a mobile phone brand had an advertisement "charging 5 minutes and talking for 2 hours" because of mobile phone flash charging technology, and it is said that it has now rolled up to "charging 5 minutes high frame king 3 hours", in fact, the field of pure electric vehicles is the same.
Some manufacturers advertise "200 kilometers in 5 minutes of charging", and now it is said that there is a technology of "400 kilometers in 5 minutes of charging".
At the theme forum of this year's World Power Battery Conference, Wu Kai, chief scientist of CATL, said that the fast charging effect of a car owned by a customer of CATL this year will reach less than 10 minutes of charging but can last more than 400 kilometers, and may be charged to 400 kilometers in 5 minutes later.
We also pull the data of the supercharging piles of various car companies horizontally to see how fast the current pure electric vehicles are.
From the data point of view, the current supercharging pile replenishment speed is actually relatively close, and it is already very stable to basically achieve 200km of energy replenishment in 5 minutes under the condition of vehicle pile cooperation.
From the data comparison, it can also be found that whether it is a new domestic car manufacturing force, or suppliers such as Huawei and Veri, their performance in overcharging is better than Tesla.
Although Tesla V4 supercharging pile has been launched abroad, it does not seem to have much advantage from the perspective of the peak charging power burst, not to mention that the current Tesla V4 supercharging station is far away from entering China.

At present, Tesla's domestic V3 supercharging power of 250kW is really not enough, and its official data has a speed of 250km in 15 minutes, which has no advantage in the face of other supercharging piles that "replenish 200km in 5 minutes".
Of course, from the perspective of actual car use, everyone will think that pure electric vehicles can be supplemented in 5 minutes to how many kilometers, can be regarded as being able to get rid of the mileage anxiety of long-distance travel during holidays, welcome to leave your answer in the comment area.
