Abstract
A data acquisition unit acquires temperature data for a plurality of battery packs mounted on different equipment (e.g., electric-powered vehicle) in a predetermined period. A statistical calculation unit calculates, for each battery pack, a statistical value based on a temperature change rate in a plurality of charging periods included in the predetermined period. A determination unit determines a temperature adjustment function of the equipment for which a deviation of the statistical value based on the temperature change rate is equal to or greater than a threshold value to be abnormal.
