PROBLEM TO BE SOLVED: To provide a battery temperature adjustment device capable of effectively utilizing heat resulting from heat radiation in a heat radiation part of a thermoelectric conversion unit at the time when a battery is cooled by the thermoelectric conversion unit, or cooling effects resulting from heat absorption in a heat absorption part of the thermoelectric conversion unit at the time when the battery is heated.SOLUTION: A battery temperature adjustment device 10 comprises: a battery 11; a Peltier unit 12 having a thermoelectric conversion element; a heat storage unit 16 having a heat storage body M; and a radiator 18 performing heat exchange. The Peltier unit 12 has a first thermal surface part 14 formed on one surface side of the thermoelectric conversion element, and a second thermal surface part 15 formed on the other surface side of the thermoelectric conversion element. The heat storage unit 16 is thermally coupled with the first thermal surface part 14 and the second thermal surface part 15, and also thermally coupled with the battery 11 and the radiator 18. |
