The biggest bottleneck in the development of pure electric vehicles in China will be eliminated if it is not solved

At present, although the largest sales of new energy vehicles are pure electric vehicles, it shows that consumers are more recognized for pure electric vehicles, but there are still very big problems.

Charging time

Charging time is an inherent problem of electric vehicles. Compared with plug-in models, pure electric vehicles carry more batteries and require longer charging time. It usually takes 8-10 hours to fill up with fuel vehicles. A box of oil only takes 5 minutes. This time is very long. Although many car companies already have fast charging technology, long-term use of fast charging will have a certain impact on battery life. In the case of no breakthrough in charging technology, Long charging time will become a major bottleneck for pure electric vehicles.

recharge mileage

Compared with a fuel truck, it can run five or six hundred kilometers with a tank of oil. The range of pure electric vehicles is generally 300 kilometers. This is still the ideal data. High-speed driving and air conditioning will have a huge impact on the cruising range. Because of the mileage anxiety, consumers will charge as soon as possible, which means that the 300km cruising range may be less than 200km in actual use, which makes it difficult for consumers to accept, and blindly accumulates power batteries for cruising range. The improvement is not very obvious, because the weight of the power battery itself will also affect the cruising range. To improve the cruising range, it is necessary to increase the energy density of the battery and the battery management system, and to manage the battery energy more efficiently, in order to have better endurance performance.

Less charging pile

The number of charging piles is also a huge problem. Originally, the mileage of pure electric vehicles is very short, and it is especially prominent in China. Compared with the United States, because of the complete infrastructure, many owners have private parking spaces, and charging is relatively convenient. Relatively concentrated, especially in some cities, parking spaces are in short supply, and the number of charging piles is small, which limits the development of pure electric vehicles, and the problem of charging piles is more prominent because of the long charging time.
