A charging system includes a locking device locking a connector provided at the end of a cable in the state where the connector is connected to an inlet provided in a vehicle; a release button for releasing locking by the locking device; a switch generating a signal indicating that the connector and the inlet are connected; a horn; and an ECU. In response to the operation of the release button, the switch stops generation of the signal. The ECU controls charging of a power storage device and detects whether the signal is issued or not. In the case where the ECU detects that generation of the signal is stopped during charging of the power storage device, the ECU causes the horn to issue an alarm.

Charging system

An AC/DC converter is configured to perform voltage conversion on power supplied from an AC power supply and supply the power to an auxiliary load during external charging in which a main power storage device is charged by the AC power supply. An auxiliary power storage device stores power to be supplied to the auxiliary load. A diode permits discharging of the auxiliary power storage device while preventing charging of the auxiliary power storage device during the external charging. A current sensor detects discharging of the auxiliary power storage device. A controller adjusts an output voltage of the AC/DC converter while confirming whether or not the auxiliary power storage device discharges, based on a detection value of the current sensor.

Vehicle charging system and electrically powered vehicle provided with the same

A vehicle includes a PCU controlling electric power supplied to a motor, a first power storage device, a second power storage device, an ECU, a charger, system main relays SMRto SMR, SMRA, SMRB, and charging relays CRto CR. The first power storage device is formed such that a first module and a second module which are separately disposed are connected in series through SMRA and SMRB. The first power storage device is connected to the PCU through SMRand SMR. The second power storage device is connected to the PCU through SMRand SMR. The charger has a capacitor that is connected to the first power storage device through CRand CRand also connected to the second power storage device through CRand CR. When charging is completed, the ECU turns on CR, CR, SMR, and SMR, and turns off SMRA, SMRB, CR, CR, SMR, and SMR

Power control device for vehicle

In a charging system for a vehicle for charging a power storage device, including the vehicle having the power storage device, and a charging cable for transmitting electric power supplied from an external power supply outside of the vehicle to the power storage device, charging information about charging performed by a charging device is set based on a signal generated by operation of an operation switch provided on a charging connector. This configuration can improve operability during charging.

Vehicle, charging cable, and charging system for vehicle

A conversion adaptor enables utilization of a standardized charge cable used when a power storage device mounted on an electrically-powered vehicle is charged by a power source provided outside of the vehicle as a universal cable for transmitting electric power to electric loads having different plug shapes that are respectively standardized from one region to another. Conversion adaptor includes a primary side connector unit configured to be connectable to a connector of charge cable, a secondary side connector unit configured so as to have a plug of an electric load, such as a home electric appliance, connected thereto, and a manipulating unit for manipulating a CCID of charge cable so that relays are switched off when connector of charge cable is connected to first connector unit.
