A temperature stabilized battery system including a battery having at least one rechargeable electrochemical cell, a Peltier type heat pump providing a hot thermal transfer face, a cold thermal transfer face and semiconductor means for transferring thermal energy between the two faces, one thermal transfer face being in thermal transfer relation to the battery and the other face being in thermal transfer relation to a heat sink. Thermal insulation surrounds at least a portion of the battery for reducing the flow of heat into and out of the battery except via the heat pump. The battery is wrapped or encased in a thermally conductive blanket which is surrounded by the insulation means.
