Abstract: An in-vehicle charging control device may be provided. The in-vehicle charging control device may comprise a control module (3), a charging socket (4) and a switching circuit (2). The charging socket (4) has a charging connection confirming terminal (CC) and a protective grounding terminal (PE). The switching circuit (2) is connected with the charging connection confirming terminal (CC) and the protective grounding terminal (PE) of the charging socket (4) respectively. The control module (3) is connected with an in-vehicle battery (1) via the switching circuit (2). The charging socket (4) is matched with a charging plug (5). The switching circuit (2) is in a conducting state when the charging plug (5) plugs in the charging socket (4) or in a disconnection state when the charging plug (5) does not plug in the charging socket (4). Further, a vehicle charging system and a vehicle may also be provided.

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.
