Abstract: A charging cable locking device locks or unlocks a charging cable in association with the locking and unlocking of a vehicle door. In the charging cable locking device, a power supply plug of the charging cable is joined to an inlet provided in a power supply opening, and the charging cable is locked when a state in which a battery is being charged by power supplied from the charging cable continues for a predetermined time.

Abstract: An electronic key registration system includes a controller arranged in a communication subject communicable with an electronic key. A registration tool is in wired or wireless connection with the communication subject. The registration tool registers the electronic key to the controller when receiving a registration permission signal. An information center is connected to a network. The registration tool includes an operator ID acquisition unit that acquires an operator ID from a key registration operator. A communication unit sends the operator ID to the information center through the network. The information center includes an operator ID verification unit that verifies the operator ID received from the registration tool. A permission information notification unit sends, when the operator ID is verified, a registration permission signal to the registration tool through the network to permit the registration tool to perform the registration process.

Abstract: An onboard system includes a switch arranged on a vehicle at a location allowing for a user to operate the switch from outside the vehicle. A control unit allows for a vehicle power supply to be switched OFF if an operation performed on the switch is detected when a power supply plug is connected to a charge inlet.

Abstract: A plug lock device that allows for a power plug fitted to an inlet to be switched between a lock state and an unlock state. The plug lock device includes a communication unit capable of communicating with the power plug and a control unit configured to identify the power plug fitted to the inlet based on the communication performed by the communication unit. The control unit is operable based on the identification of the power plug in a lock restriction mode that restricts switching of the power plug to the lock state.
