The invention relates to a vehicle-mounted low-voltage power supply device for a battery electric vehicle. The vehicle-mounted low-voltage power supply device is characterized in that a high voltage input end and a low voltage output end are arranged on the vehicle-mounted low-voltage power supply device; the vehicle-mounted low-voltage power supply device is composed of a DC-DC module, a center control module, an electricity supplementing circuit, a control output circuit and a build-in storage battery; the DC-DC module is connected with the electricity supplementing circuit, and the control output circuit; the center control module is connected with the DC-DC module, the electricity supplementing circuit, the control output circuit and the build-in battery; the build-in battery is connected with the electricity supplementing circuit; the input end of the DC-DC module is the high voltage input end of the vehicle-mounted low-voltage power supply device; the output end of the control output circuit is the low voltage output end of the vehicle-mounted low-voltage power supply device. The vehicle-mounted low-voltage power supply device solves the problem of complexity in the electric system of the whole vehicle, caused by the existing structure, the whole vehicle system arrangement difficulty is reduced, system reliability is enhanced and the space is effectively saved.
