PROBLEM TO BE SOLVED: To provide a battery protection device of a vehicle which maintains a proper temperature of a battery under a high temperature atmosphere even if electric power is supplied thereto.SOLUTION: A battery protection device 3 includes: a battery case 30 coated by a high heat insulation structure including a vacuum heat insulation layer 31; and a heat pipe cycle 34 passing through the battery case 30 and allowing a refrigerant to circulate. The heat pipe cycle 34 has: a heat radiation part 34a; a heat absorption part 34b; and circulation passages 34c and 34d. An interior part of the heat pipe cycle 34 is decompressed so that a boiling point of the refrigerant becomes lower than a usable temperature of the battery 2.SELECTED DRAWING: Figure 2

    【課題】高温の雰囲気下で、電力を供給しなくてもバッテリーを適温に保つことができる自動車のバッテリー保護装置を提供する。【解決手段】バッテリー保護装置3は、真空断熱層31を含む高断熱構造で被覆されたバッテリーケース30と、その内部を通って冷媒を循環させるヒートパイプサイクル34とを備える。ヒートパイプサイクル34は、放熱部34aと、吸熱部34bと、循環経路34c、34dとを有している。バッテリー2の使用可能温度よりも冷媒の沸点が低くなるように、ヒートパイプサイクル34の内部が減圧されている。【選択図】図2
