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.
