To suppress variations of a temperature of an on-vehicle battery.SOLUTION: A vehicle comprises: a heat exchange plate including a cooling liquid layer and a coolant layer between a first surface and a second surface; and a battery module group that is arranged along the first surface of the heat exchange plate. In a space between the first surface and the second surface of the heat exchange plate, a whole of the cooling liquid layer provides a first region in a plan view, and the whole coolant layer provides a second region in a plan view. In the first surface of the heat exchange plate, a whole battery module group provides a third region in a plan view. A center of the third region of the battery module group is arranged so as to be overlapped with the first and second regions, and makes a pump of the cooling liquid layer operate in the case where a difference between a temperature A of a secondary battery cell near from the center of the battery module group and a temperature B of the secondary battery cell near from the periphery of the battery module group exceeds a constant value.SELECTED DRAWING: Figure 2

    【課題】車載電池の温度のバラツキを抑制する。【解決手段】車両は、第1面と第2面との間に冷却液層及び冷媒層を有する熱交換プレートと、熱交換プレートの第1面に沿って配置された電池モジュール群とを備え、熱交換プレートの第1面と第2面の間において、冷却液層全体は平面視で第1領域を備え、冷媒層全体は平面視で第2領域を備え、熱交換プレートの第1面において、電池モジュール群全体は平面視で第3領域を備え、電池モジュール群の第3領域の中心は、第1領域と第2領域とに重なって配置され、電池モジュール群の中央寄りの二次電池セルの温度Aと、電池モジュール群の周辺寄りの二次電池セルの温度Bとの差が一定値を超えた場合、冷却液層のポンプを動作させる。【選択図】図2
