A few days ago, Wang Zidong, director of the National 863 Electric Vehicle Major Special Power Battery Testing Center, said that the main factor restricting the popularity of pure electric vehicles is not the cruising range of the vehicle, but the efficiency
of use.
Wang Zidong pointed out that the energy conversion efficiency of pure electric vehicles is much higher than that of traditional internal combustion engines, but in terms of use efficiency, it cannot be used
as a daily means of transportation.
Wang Zidong explained that the current pure electric vehicles on the market have a relatively good charging level, which can only charge 80% in 20 minutes and have a range of about 100-120 kilometers
.
At present, charging handouts are not perfect
.
In fact, even if there are charging piles everywhere, the owner is unlikely to charge on the spot, assuming that there are 2 cars in front, then the owner will have to wait for 1 hour
.
Such efficiency cannot be used
as a daily means of transportation.
Wang Zidong believes that charging an electric vehicle with a mileage of less than 200km, if it cannot solve the problem of rapid replenishment of electric vehicle energy, even if the charging pile is popularized, pure electric vehicles can not completely replace traditional cars, it can only be used as a supplement, suitable for short-distance travel
.
Power battery has become the bottleneck technology
for the development of strategic new industries of electric vehicles in China.
At present, there are many battery research and production enterprises in China, but the overall strength is not strong
.
Wang Zidong pointed out that there are 2,000 to 3,000 lithium battery manufacturers in China, and in the absence of core technology and the shortage of power batteries, many enterprises have begun to produce power batteries
.
However, power batteries and traditional lithium batteries are completely different in manufacturing technology
