Summary:To suppress loss and corruption of data stored in a memory in a control device.SOLUTION: An ECU executes processing of including: a step (S100) of determining whether or not there is a request for rewriting battery information; a step (S102) of calculating a SOC of an assembled battery when it is determined that there is a request for rewriting the battery information (YES in S100); a step (S104) of determining whether or not the SOC of the assembled battery is equal to or higher than a threshold SOC (0); a step (S106) of executing battery information rewriting processing when the SOC is equal to or higher than the threshold SOC (0) (YES in S104); and a step (S108) of requesting charging of the assembled battery when the SOC is lower than the threshold SOC (0) (NO in S104).SELECTED DRAWING: Figure 3 【課題】制御装置内のメモリに記憶されたデータの消失およびデータ化けの発生を抑制する。【解決手段】ECUは、電池情報の書き換え要求があるか否かを判定するステップ(S100)と、電池情報の書き換え要求があると判定される場合に(S100にてYES)、組電池のSOCを算出するステップ(S102)と、組電池のSOCがしきい値SOC(0)以上であるか否かを判定するステップ(S104)と、SOCがしきい値SOC(0)以上であるときに(S104にてYES)、電池情報の書き換え処理を実行するステップ(S106)と、SOCがしきい値SOC(0)よりも低いときに(S104にてNO)、組電池の充電を要求するステップ(S108)とを含む、処理を実行する。【選択図】図3
