To provide a storage battery temperature control system capable of excellently executing a cooling control of a storage battery even if an electric device with a heat generation is arranged in a closed space in which the storage battery is housed.SOLUTION: A storage battery temperature control system includes: first to third temperature sensors 6a to 6c obtaining a power storage battery 1 and its circumference temperature; fourth and fifth temperature sensors 6d and 6e, obtaining an AC/DC unit 2 and its circumference temperature; sixth and seventh temperature sensors 6e and 6f, obtaining a DC/AC unit 3 and its circumference temperature; a controller 5 controlling an air conditioner 4; and a threshold value storage part 7 storing a setting value of an upper limit inclination threshold value of an upper limit to an upper limit attention threshold value and temperature rising speeds to temperature information obtained by the temperature sensors 6a to 6f. The controller 5 controls the air conditioner 4 to reduce an inner temperature of a power storage board 10 when at least one of the temperature information obtained by the temperature sensors 6a to 6f exceeds the attention threshold value or at least one of the temperature rising speeds exceeds the inclination threshold value.SELECTED DRAWING: Figure 1 【課題】 蓄電池が収容された閉空間に発熱を伴う電気機器が配置されていても、蓄電池の冷却制御を良好に実施できる蓄電池温度制御システムを提供する。【解決手段】 蓄電池１とその周辺温度を入手する第１〜３温度センサ６ａ〜６ｃと、ＡＣ／ＤＣユニット２とその周辺温度を入手する第４，５温度センサ６ｄ，６ｅと、ＤＣ／ＡＣユニット３とその周辺温度を入手する第６，７温度センサ６ｅ，６ｆと、空調装置４を制御する制御コントローラ５と、温度センサ６ａ〜６ｆが入手した温度情報に対して、個々に上限の注意閾値及び温度上昇速度に対する上限の傾き閾値の設定値を記憶する閾値記憶部７とを有し、制御コントローラ５は個々の温度センサ６ａ〜６ｆが入手した温度情報の少なくとも１つが注意閾値を超えたら、或いは温度上昇速度の少なくとも１つが傾き閾値を超えたら、空調装置４を制御して蓄電池盤１０の内部温度を下げる。【選択図】 図１
