To enable auxiliary heating with small electric power and enable the interior of a vehicle cabin to be heated early even in a cold state with small electric power.SOLUTION: A heat accumulation unit 2 is installed at a steering support beam 5 located close to an air conditioning duct 23a of an air conditioner 23. Heat from a heating source 13 generated by behavior of an electric vehicle is accumulated in a heat accumulation material 2e of the heat accumulation unit 2. A heating valve 2d is opened and an air conditioning fan 23e of the air conditioner 23 is operated at a predetermined timing before a driver gets in the vehicle to supply the heat of the heat accumulation material to the air conditioning duct 23a and thereby perform auxiliary heating.SELECTED DRAWING: Figure 1

    【課題】少ない電力での補助暖房を可能とし、冷態時においても少ない電力で車室内を早期に昇温させることができるようにする。【解決手段】空調装置23の空調用ダクト23aに近接しているステアリングサポートビーム5に蓄熱ユニット2を装填する。この蓄熱ユニット2の蓄熱材2eには電動車両の挙動で発生する発熱源13からの熱が蓄熱されており、運転者が乗車する前の所定タイミングで暖房バルブ2dを開弁させると共に空調装置23の空調ファン23eを稼動させ、蓄熱材の熱を空調用ダクト23aに供給することで補助暖房を行う。【選択図】図1
