The invention provides an all-in-one vehicle-mounted power supply device, a motor controller and a power assembly. Power control circuits of a compressor and a heater are integrated to save hardware cost. The vehicle-mounted power supply device comprises a shell, and a power conversion circuit, a switch module and a compressor motor driving circuit which are accommodated in the shell. And a compressor motor interface and a heating module interface are arranged on the surface of the shell. The power conversion circuit is used for receiving alternating current and outputting first direct current to charge the power battery or supply power to the compressor motor driving circuit. The compressor motor driving circuit comprises three bridge arms which are connected in parallel, the two ends of the three bridge arms are used for receiving first direct current or receiving power supplied by a power battery, and the middle point of each bridge arm is used for being connected with a phase winding of a compressor motor through a compressor motor interface. Wherein the bridge arm midpoint of the at least one bridge arm is used for driving the heating module through the heating module interface, and the switch module is used for connecting or disconnecting the bridge arm midpoint of the at least one bridge arm and the heating module.
