Abstract: An in-vehicle charging control device may comprise a control module, a charging socket, and a switching circuit. The charging socket has a charging connection confirming terminal (CC) and a protective grounding terminal (PE). The switching circuit is connected with the charging connection confirming terminal (CC) and the protective grounding terminal (PE) of the charging socket. The control module is connected with an in-vehicle battery via the switching circuit. The charging socket matches with a charging plug. The switching circuit is in a conducting state when the charging plug is plugged in the charging socket and in a disconnection state when the charging plug is not plugged in the charging socket.

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 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.
