It's different. Charging time: Fast charging for half an hour can fill 80% of the battery capacity. After more than 80%, in order to protect the safety of the battery, the charging current becomes smaller, and the time to charge to 100% will be longer. Slow charging time is too long, generally take 6 hours to 8 hours. Impact on the battery: the fast charging battery causes some damage, and the slow charging extends the battery life.
Charging mode: Fast charge: DC charging pile built-in power conversion module, which can convert the AC power of the grid into DC power, without the conversion of the car charger, directly connected to the car battery.
Slow charge: the AC charging pile does not have a power conversion module, do not do AC\/DC conversion, through the car charger converted to direct current and then input the battery.
