The invention relates to a vehicle charging system, and belongs to the technical field of electric vehicle batteries, the system comprises a power multiplexing unit, a wired charging unit and a wireless charging unit, the input end of the power multiplexing unit is used for being connected to a power grid, and alternating current of the power grid is converted into direct current to be output; the output end of the power multiplexing unit is connected to the wired charging unit through a first switch and connected to the wireless charging unit through a second switch, the first switch and the second switch form interlocking, when a wired charging signal is received, the first switch is closed, so that the second switch is kept in an off state, and when a wireless charging signal is received, the second switch is kept in an off state. The system can only be in one charging state and can not be influenced by other circuits when supplying power to the vehicle, so that the power supply safety is guaranteed. 本发明涉及
