Different, the slow charge of the car is 15%~20% more than the fast charge, the car can not be fully charged when the fast charge, the charge speed will be significantly slower when the power reaches more than 80%, and the power will be locked in 85-90%, can not be fully charged, this situation is designed to ensure the life of the battery. Rapid charging itself has certain damage to the battery, especially in the late charging period, which will cause high voltage of individual batteries, resulting in rapid aging of the battery.
Slow charging does not have this situation, slow charging, due to the long charging time, the battery has sufficient chemical reaction time, resulting in the battery charged into the electricity, completely absorbed by the battery.
In this way, the efficiency of the battery will be much higher, the battery will store a lot of electricity, and will not have a significant impact on the service life. It is still recommended to use slow charging, and fast charging can be used to shorten the charging time when you go out.
