Zusammenfassung:To further improve fuel consumption of an engine in external power supply.SOLUTION: A vehicle includes an engine, a power generator, a power storage device, and an external power supply part. The vehicle includes a control device which stops power storage to the power storage device from the power generator when a charged state of the power storage device is equal to or more than a first threshold, and starts power storage to the power storage device from the power generator when the charged state of the power storage device is less than a second threshold lower than the first threshold. The control device sets a third threshold larger than the first threshold in place of the first threshold in a period during which stored power is supplied from the external power supply part, and stops power storage from the power generator to the power storage device when the charged state of the power storage device is equal to or more than a third threshold. The control device stores power from the power generator to the power storage device when the charged state of the power storage device is equal to or more than a second threshold when a temperature of the engine is equal to or less than a temperature determination threshold.SELECTED DRAWING: Figure 3 【課題】外部給電におけるエンジンの燃費を一層向上させる。【解決手段】車両は、エンジンと、発電機と、蓄電装置と、外部給電部とを含む。車両は、蓄電装置の充電状態が第1閾値以上となった場合に、発電機から蓄電装置への蓄電を停止させ、蓄電装置の充電状態が第1閾値よりも低い第2閾値未満となった場合に、発電機から蓄電装置への蓄電を開始させる制御装置を備える。制御装置は、外部給電部により蓄電電力を供給している期間に、第1閾値に代えて当該第1閾値よりも大きな第3閾値を設定し、蓄電装置の充電状態が第3閾値以上となった場合に、発電機から蓄電装置への蓄電を停止させる。また、制御装置は、エンジンの温度が温度判定閾値以下となった場合に、蓄電装置の充電状態が第2閾値以上であっても発電機から蓄電装置への蓄電を行う。【選択図】図3
