In that case, the detection part 11 by an optical sensor etc. detects that a vehicle exists in the vehicle stop position corresponding to the connector 8-1 for charge, for example.

  Based on the detection result of the detection unit 11, the control unit 3 selects a charging connector corresponding to a vehicle position where no vehicle is present, and outputs a lock signal to the connector storage unit in which the selected charging connector is stored. To do. Therefore, the control unit 3 does not output a lock signal to the connector storage unit in which the charging connector 8-1 corresponding to the vehicle stop position where the presence of the vehicle is detected is stored.

  As a result, the driver of the electric vehicle 12-1 can pull out the charging connector 8-1 from the connector housing portion to perform charging, connect to the charging port of the electric vehicle 12-1, and operate the input unit 2. And start charging.

  On the other hand, the control unit 3 selects the charging connector 8-2 corresponding to the vehicle position where no vehicle exists based on the detection result of the detection unit 11, and the connector storage in which the selected charging connector 8-2 is stored. A lock signal is output to the unit.

Therefore, when the connector housing section in which the charging connector 8-2 is housed receives the lock signal output from the control section 3, the connector housing section locks the housed charging connector 8-2 so that it cannot be taken out. . Therefore, even if a person for mischief purpose etc. tries to pull out the charging connector 8-2 from the connector housing portion, he / she cannot be pulled out, so that mischief and the like can be prevented and safety can be ensured. It is a figure explaining operation | movement when the connector for charge does not exist in a predetermined | prescribed accommodation place in the charging device 1 of an example. As described above, the sensor unit 9 detects whether or not each of the plurality of charging connectors 8-1 to 8-n is housed in each of the corresponding connector housing portions.
