Abstract: A power supply system for an electric vehicle includes a battery module, a first DC/DC converter, a second DC/DC converter, a first switch, a second switch and a third switch. The battery module has a negative electrode, a first positive electrode and a second positive electrode. The first DC/DC converter has an input terminal connected with the second positive electrode. The second DC/DC converter has an input terminal connected with the second positive electrode. The first switch is connected between the second positive electrode and the first DC/DC converter. The second switch is connected between the second positive electrode and the second DC/DC converter. The third switch is connected between the first positive electrode and an output terminal of the second DC/DC converter.

Abstract: An energy conversion device is provided, including a motor coil (11), a bridge arm converter (12), and a bidirectional bridge arm (13). The bridge arm converter (12) is separately connected to the motor coil (11) and the bidirectional bridge arm (13). The motor coil (11), the bridge arm converter (12), and the bidirectional bridge arm (13) are all connected to an external charging port (10). Both the bridge arm converter (12) and the bidirectional bridge arm (13) are connected to an external battery 200. The motor coil (11), the bridge arm converter (12), and the external charging port (10) form a DC charging circuit for charging the external battery 200. The motor coil (11), the bridge arm converter (12), the bidirectional bridge arm (13), and the external charging port (10) form an AC charging circuit for charging the external battery (200). The motor coil (11), the bridge arm converter (12), and the external battery (200) form a motor drive circuit.
