Abstract: The present invention contemplates a hybrid vehicle capable of changing an amount to be charged to an electric power storage device in accordance with whether it is externally charged. The hybrid vehicle includes a control device inquiring of an occupant of the vehicle whether the occupant has an intention to go to a charging location for example at home. If so, the control device sets a target value for the electric power storage device's amount of a state (SOC) to have a value smaller than when the occupant does not have an intention to go to the charging location. This allows as much energy as possible to be received at the charging location and a vehicle can thus be obtained that less depends on an internal combustion engine and contributes to environmental protection.

Abstract: 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.

Abstract: A charger converts electric power supplied from an AC power supply external to a vehicle into a predetermined charging voltage. A relay is provided between the charger and a power storage device. A charging ECU controls the charger and the relay. An AC/DC converter converts electric power supplied from the AC power supply into a predetermined power supply voltage and supplies the electric power converted into the power supply voltage to a charging device constituted of the charger, the relay and the charging ECU. While the power storage device is charged by the AC power supply, the charging device operates with the operating electric power it receives from the AC/DC converter.

Abstract: An SOC target is a control target of a remaining capacity of an accumulation device having a characteristic that the internal loss increases in a low SOC region. The SOC target is set to a first value corresponding to a remaining capacity target upon reaching a predetermined point when the remaining travel distance up to a predetermined point where the accumulation device can be charged from outside has become shorter than a predetermined distance. Thus, the hybrid vehicle can perform EV travel by power consumption of the accumulation device. On the other hand, when the remaining travel distance is not smaller than the predetermined distance Dr, the SOC target is set to a second value in the SOC region where the loss of the accumulation device is smaller than the first value.
