Comparative pure fuel vehicles, pure electric vehicles slightly higher prices, which led many consumers to choose friends not a pure electric car, but chose instead to fuel cars. So, where pure electric vehicles cost reduction and space in it?
The first is a battery. The reason why the cost of electric vehicles so high, the most important reason is the high cost of power battery pack. Even after many rounds of price, ternary lithium costs remain at 1 yuan per watt. In other words, a life mileage of 400km, the 60kWh battery capacity of pure electric vehicles, lithium batteries will cost three yuan at about 6 million, so a pure electric car is priced at 150,000 yuan so, then the cost of lithium batteries three yuan accounted for about 40 percentage. So, we want to reduce the cost of electric vehicles, the first three yuan to reduce the cost of lithium batteries. 
Furthermore, it is to improve the pure electric vehicle technology cars. The use of electric vehicle platforms, as well as motor, electric drive and electric control three-in technology, we can improve the pure electric vehicle technology cars to a large extent, thereby reducing the cost of electric vehicles.
Finally, it is the current high cost of research and development of pure electric vehicles. In contrast to fuel cars, car prices at present a lot of pure electric vehicle research and development is still in the stage is not perfect, coupled with the small number of electric vehicles, and therefore allocated to R & D costs are also high on each vehicle. I believe that with a pure electric car ownership increases, these costs will be reduced.
