Especially for exhibition vehicles, in order to show the vehicle functions to users, the vehicle is often started for a long time. In order to avoid traditional battery feeding, the battery will be connected to an external power supply. For 48V and even 300V-300V HEV models, there are no external conditions and the power battery cannot be replenished.
