Background

Along with popularization of electric vehicles, how to effectively supply electric energy for electric vehicles with insufficient electric energy in time becomes a very concerned problem for manufacturers and owners. The mainstream solution in the current market is to use a charging mode to configure an AC slow charging pile or a DC fast charging pile in a parking space. However, the slow charging mode needs to occupy a parking space for charging for a long time, while the fast charging mode has a charging current which is ten times or even tens times of that of the conventional charging current, the cycle life of the power battery pack can be reduced, and the charging does not generally reach a full charging state. The power battery replacement mode is adopted in the power battery replacement station, the battery pack with depleted energy is directly replaced by the fully charged battery pack, and the electric energy supply is completed in the time of minutes, so that the power battery replacement station is a very efficient electric energy supply mode.
