s106: and determining whether each type of information meets the switching condition corresponding to each type of information according to each type of information.
Optionally, in an embodiment of the present application, the plurality of information may include: a charging state, a charging demand current, a current charging type, an identified historical charging type.
In one embodiment of the present application, the handover condition may be: the current charging type is that the current in charging and the current required for charging are inconsistent with the current charging current, and the current charging type is inconsistent with the confirmed historical charging type.

And if the charging gun meets the charging switching condition, controlling the power unit corresponding to the current charging type of the charging gun to be shut down, and controlling the path between the power unit corresponding to the current charging type and the charging gun to be disconnected.
For example, the following steps are carried out: if the charging gun A executes the charging operation before switching and meets the charging switching condition, controlling a power unit corresponding to the current charging type of the charging gun A: the ACDC1 power supply unit, the ACDC2 power supply unit and the ACDC power supply unit are shut down, the switch K1A +, the switch K1A-, the switch KNA + and the switch KNA-are controlled to be opened, at the moment, the path between the charging gun A and the corresponding power unit is disconnected, and the charging gun A stops working.
And after the switched target charging type is determined subsequently, the corresponding power unit is controlled to start, and the corresponding switch is controlled to be closed, so that a channel between the power unit and the charging gun is conducted.
When the charging gun meets the charging switching condition, the power unit corresponding to the current charging type of the charging gun is controlled to be shut down, and the passage between the power unit corresponding to the current charging type and the charging gun is controlled to be disconnected, so that the waste of resources can be reduced, the power unit which is not needed at present is timely closed, and the recovery of the power unit and the passage resources is realized. It should be noted that, in this process, the output charging type is empty, the charging gun maintains the charging state, but the power output is interrupted.
Optionally, on the basis of the foregoing embodiments, the embodiments of the present application may further provide a charging control method, which is described below with reference to the accompanying drawings.

And the battery voltage can be monitored in real time in the charging process, whether the battery voltage exceeds the upper voltage limit of the charging gun or not is judged, if yes, whether the charging type is switched or not is further judged, and subsequent charging is executed according to the judgment result. The setting method can realize that vehicles with different charging types are charged through one charging device, the charging process is continuous, and the charging gun does not need to be replaced even if the voltage type is changed, so that the use feeling of a user is improved.
