The invention provides a vehicle-mounted power supply device, a power assembly and an electric vehicle. The vehicle-mounted power supply device comprises a shell, a circuit board, an alternating current control chip and a direct current control chip. Wherein the shell is used for accommodating the circuit board, the alternating-current control chip and the direct-current control chip, and the shell comprises an alternating-current input interface and a high-voltage direct-current interface. The circuit board is used for bearing electrical components of the power factor correction circuit and the power conversion circuit, the power factor correction circuit is used for receiving power supplied by an alternating current power supply through the alternating current input interface and outputting direct current, and the power conversion circuit performs voltage conversion on the direct current and outputs first direct current through the high-voltage direct current interface to charge the power battery. The AC control chip is used for controlling the operation of the power factor correction circuit, and the DC control chip is used for controlling the operation of the power conversion circuit, thereby facilitating the reduction of the size and weight of the vehicle-mounted power supply device, and enabling the structure of the vehicle-mounted power supply device to be more compact.
