Dongfeng Nissan Xuan Yi pure electric charging method:

1. Charging port design. Because the BMS of the fast charging battery needs to be shared, the fast charging port and the IGBT module are generally put together, that is to say, the front drive is put in front of the rear drive;
< br >
2, before and after separation is not impossible, but pull a very thick cable from the front to the back, then whether it is cost or space utilization is not cost-effective;
< br >
3. Space design. Some people think that electric cars are good design, solve the battery problem and other things are very simple. But this battery problem can not be solved, the energy density of the battery is insufficient, only 100-180Wh \/kg, and the calorific value of gasoline is about 12.2 degrees of electricity \/kg, almost 100 times more, of course, the transmission efficiency, the average efficiency of the motor is more than 3 times higher, reflected in the energy density of the system, gasoline is also 30-40 times the battery.
