To provide a vehicle battery temperature adjusting device capable of curbing extreme reductions in temperatures of a battery and a surrounding area thereof and thereby securing sufficient start-up performance of an engine.SOLUTION: A battery temperature adjusting device 900 of a vehicle mounted with a battery 501 in an engine room 100 comprises: a housing 503 which stores the battery 501 therein with a gap 504 in between; a first air duct 301; a second air duct 302 with an upstream side thereof communicated with the gap 504; a housing intake port 507A which is open on the housing 503 toward an engine 201; an intake amount adjusting valve 305 which adjusts a first intake amount through the first air duct 301 and a second intake amount through the second air duct 302; and a controller 800 which controls operation of the intake amount adjusting valve 305. The controller 800 makes a ratio of the second intake amount higher when an ambient temperature is determined to be lower than a first threshold temperature than the ratio when the ambient temperature is equal to or higher than the first threshold temperature.SELECTED DRAWING: Figure 1

    【課題】バッテリ及びその周辺の温度の極度の低下を抑制して、エンジンの十分な始動性能を確保できる、車両のバッテリ温度調整装置を提供する。【解決手段】エンジンルーム100内にバッテリ501を搭載した車両のバッテリ温度調整装置900であって、間隙504を有した状態で、内側にバッテリ501を収容する箱体503と、第1エアダクト301と、上流側が間隙504に連通する第2エアダクト302と、箱体503に設けられ、エンジン201に向かって開口する箱体吸気口507Aと、第1エアダクト301からの第1吸気量と、第2エアダクト302からの第2吸気量と、を調整する吸気量調整バルブ305と、吸気量調整バルブ305の作動を制御するコントローラ800と、を備え、コントローラ800は、雰囲気温度が第1閾値温度未満と判定した場合には、雰囲気温度が第1閾値温度以上と判定した場合と比べて、第2吸気量の割合を増加させる。【選択図】図1
