To reduce electrical power required to heating within a cabin of an electric vehicle as much as possible.SOLUTION: A heating system of an electric vehicle 1 contains a cooling medium circulation system which contains a circulation cooling medium path 7 in which a cooling medium circulates and a cooling medium pump 9 which brings cooling medium into communication within circulation cooling medium path, a heat transmission panel 11 which faces to cabin 2 internal face and transmits heat from the cooling medium to the cabin by one part of the circulation cooling medium path abutting, inverter heat exchange means which thermally emits operation waste-heat of an inverter 5 for operating a drive motor to the cooling medium within circulation cooling medium path and circuit heat exchange means for charging which thermally emits the operation waste-heat of a circuit 6 for charging of a battery for driving to the cooling medium within the circulation cooling medium path and heats the cabin via the heat transmission panel by the operation waste-heat of the inverter during travel and by the operation waste-heat of the circuit for charging during charge.SELECTED DRAWING: Figure 1

    【課題】 電気自動車の車室内の暖房に要する電力をできるだけ低減する。【解決手段】 電気自動車1の暖房システムは、冷媒が循環する循環冷媒路7と冷媒を循環冷媒路内に流通させる冷媒ポンプ9とを含む冷媒循環システムと、車室2内面に面し循環冷媒路の一部が当接して冷媒から車室内へ熱を伝達させる熱伝達パネル11と、駆動モータの作動用インバータ5の動作排熱を循環冷媒路中の冷媒へ放熱するインバータ熱交換手段と、駆動用バッテリの充電用回路6の動作排熱を循環冷媒路中の冷媒へ放熱する充電用回路熱交換手段とを含み、走行中にはインバータの動作排熱により、充電中には電用回路の動作排熱により、熱伝達パネルを介して、車室内を暖房する【選択図】 図1
