To provide a battery cooling device capable of improving energy efficiency.SOLUTION: A battery cooling device includes: a battery housing for housing first and second batteries at the inside thereof, the housing including an introduction port introducing outside air into the interior, a discharge port discharging the introduced outside air to the outside, and an internal air passage communicating between the introduction port and the discharge port to heat exchange between the outside air and the first and second batteries; and Peltier elements provided on side surfaces of the first and second batteries on an internal air passage side, respectively. The discharge port is provided at a position higher than the introduction port in a vehicle height direction, and each side surface where the Peltier element is provided is a side surface along the vehicle height direction.SELECTED DRAWING: Figure 1

    【課題】エネルギー効率を向上させることができるバッテリの冷却装置を提供すること。【解決手段】第1および第2バッテリを内部に収容するハウジングであって、外気を内部に導入する導入口、導入された前記外気を外部に排出する排出口、並びに前記導入口と前記排出口とを連通し、前記外気と前記第1および第2バッテリとを熱交換させる内部通風路、を備えるバッテリハウジングと、前記第1および第2バッテリの前記内部通風路側の側面にそれぞれ設けられるペルチェ素子と、を含み、前記排出口は、車高方向において、前記導入口よりも高い位置に設けられ、前記ペルチェ素子が設けられる前記側面は、車高方向に沿った側面であること。【選択図】図1
