In this embodiment, the infrared signal transmitting terminal 151 and the infrared signal receiving terminal 152 may be respectively disposed near the first charging connection terminal 111 and the second charging connection terminal 112 of the charging plug, so that when the charging plug is inserted into the vehicle charging interface, a signal propagation path between the infrared signal transmitting terminal 151 and the infrared signal receiving terminal 152 is blocked, and the infrared signal receiving terminal 152 cannot receive the infrared rays emitted by the infrared signal transmitting terminal 151; on the contrary, when the charging plug is unplugged from the vehicle charging interface, no shielding object is arranged in a signal propagation path between the infrared signal transmitting terminal 151 and the infrared signal receiving terminal 152, and the infrared signal receiving terminal 152 cannot receive the infrared rays transmitted by the infrared signal transmitting terminal 151. If the infrared signal receiving terminal 152 can receive the infrared rays emitted from the infrared signal emitting terminal 151, a signal is sent to the intelligent charging device server, which indicates that the charging plug is completely unplugged from the charging interface. If the infrared signal receiving terminal 152 does not receive the infrared rays emitted from the infrared signal emitting terminal 151, the intelligent charging device server does not receive the signal from the infrared signal receiving terminal 152. In this embodiment, the shapes and sizes of the infrared signal transmitting terminal 151 and the infrared signal receiving terminal 152 may be set to match the shapes and sizes of the charging interfaces, so that the charging plug may be inserted into the charging interfaces to stabilize the charging plug during charging.
