To avoid or suppress a problem caused by permeation of electrolyte from a battery on the basis of the amount of permeation of the electrolyte out of the cells of the secondary battery or the amount of remaining electrolyte.SOLUTION: A control device 60 includes a calculation unit 62 that calculates the electrolyte permeation amount on the basis of a temperature history of a secondary battery, a determination unit 64 that determines a predetermined gas content on the basis of the ratio of the electrolyte permeation amount to the empty volume of a container housing the secondary battery and one or more first threshold values, and a control unit 66 that generates predetermined notification information when a predetermined gas content can be affirmed.SELECTED DRAWING: Figure 1
【課題】二次電池のセル外への電解液の透過量ないし残存電解液量に基づいて、電池からの電解液の透過に基づく不具合を回避又は抑制する。【解決手段】制御装置60は、二次電池の温度履歴に基づいて電解液透過量を算出する算出部62と、二次電池を収容する収容体の空き容積に対する電解液透過量の比と1又は複数の第1閾値とに基づいて、所定のガス含有量について判定する判定部64と、所定のガス含有量を肯定できるとき、所定の通知情報を作成する制御部66と、を備えている。【選択図】図1
