A data acquisition unit (111) acquires temperature data for a predetermined period of time for a plurality of battery packs mounted in different devices (e.g., electric vehicles). A statistical calculation unit (113) calculates, for each battery pack, a statistical value based on the temperature change rate of a plurality of charging periods included in a predetermined period. The determination unit (114) determines that the temperature adjustment function of the device for which the deviation of the statistical value of the temperature change rate is equal to or greater than a threshold value is abnormal.

    数据取得部(111)取得被搭载于不同的设备(例如,电动车辆)的多个电池组的预定期间的温度数据。统计运算部(113)针对每个电池组,算出基于预定期间中包含的多个充电期间的温度变化速度的统计值。判定部(114)将温度变化速度的统计值的偏差为阈值以上的设备的温度调整功能判定为异常。
