At present, the mileage of new energy vehicles is generally 200 to 300 kilometers, and there is longer life. But after driving for a period of time, the actual mileage is quite different from the official publicity.
1. Electric quantity estimation
2. Battery consistency problem
3. Capacity attenuation of batteries
With the change of temperature and environment, the endurance of the battery will be directly affected. Therefore, new energy vehical industry now urgently needs to solve the problem of battery pack capacity attenuation.
but in writer's opinion, to solve the battery navigation problem, is not only the problem of battery power itself, but an overall design of electric performance of the electric vehical car. e.g. BMS etc.
