Because of the good storage characteristics and controllability of battery, in the premise of meeting the changing needs, the operators of battery swapping station for electric vehicles can respond to the incentive measures from the power dispatching department, and meet the system operating demands. Firstly, according to the state parameters of the battery packs in a battery swapping station, the state matrix of battery packs is established. Secondly, the battery packs clustered in the light of status, and the battery packs, which are in controllable state, are controlled. Finally, recursive thought is used to study controllable load margin boundaries of backup batteries in the battery swapping station, and then the battery swapping station operators are guided to draw up corresponding charging plans based on the operation target of power dispatching department, reaching the purpose of balancing load and improving area load characteristics.
