PROBLEM TO BE SOLVED: To provide a warmup device of a hybrid vehicle which can quickly warm up a battery at a low temperature without causing a change of a layout and an increase of cost, and can improve fuel economy.SOLUTION: In a vehicle (1) which uses an engine (2) and an electric motor (3) as drive sources, when a temperature of a battery (11) is lower than a prescribed temperature threshold (T2) which is lower than a prescribed temperature (T1), and an inverter (10) is brought into a three-phase short-circuited state while rotating the electric motor (3), the battery (11) is warmed up by circulating a refrigerant of a power supply cooling circuit via the inverter (10) and the battery (11), and when the temperature of the battery (11) is not lower than the prescribed temperature threshold, the battery (11) is warmed up by making the electric motor (3) generate a drive force at a positive side or a negative side.SELECTED DRAWING: Figure 3

    【課題】レイアウトの変更やコストの増加を招くことなく、低温時において速やかにバッテリを暖機することができ、ひいては燃費を向上させることのできるハイブリッド車両の暖機装置を提供すること。【解決手段】エンジン(2)と電動機(3)とを駆動源とする車両(1)において、バッテリ(11)の温度が所定温度(T1)より低い所定温度閾値(T2)未満である場合には、電動機(3)を回転させつつインバータ(10)を三相短絡状態とし、インバータ(10)及びバッテリ(11)を経由する電源冷却回路の冷媒を循環させることで前記バッテリ(11)の暖機を行い、バッテリ(11)の温度が所定温度閾値以上である場合には、電動機(3)に正側又は負側の駆動力を発生させることでバッテリ(11)の暖機を行う。【選択図】図3
