In a possible example, please refer to fig. 3, and fig. 3 is a schematic structural diagram of a control unit according to an embodiment of the present application. As shown, the control unit 33 includes a first switching subunit 332, asecond switching subunit 333, and acontrol subunit 331; the first switch subunit 332 is connected to the wired charging unit 31 and the power unit 34, and is configured to control a connection relationship between the wired charging unit 31 and the power unit 34; thesecond switch subunit 333 is connected to the wireless charging unit 32 and the power unit 34, and is configured to control a connection relationship between the wireless charging unit 32 and the power unit 34; thecontrol subunit 331 is connected to the first switch subunit 332 and thesecond switch subunit 333, and is configured to obtain a detection signal, and control the on/off states of the first switch subunit 332 and thesecond switch subunit 333 according to the detection signal.

Therefore, the sampling sub-unit is shared by the wired charging unit and the wireless charging unit, so that the current charging state can be controlled in real time, the cost, the volume and the weight of automobile parts can be reduced, and the spatial layout of the automobile is optimized.
