Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a battery system which improves reliability on the basis of monitoring of usage histories of a battery module.SOLUTION: A battery system includes: a battery module configured by connecting in series a plurality of battery cell groups having a plurality of battery cells connected in series; a plurality of integrated circuits which are provided corresponding to each battery cell group of the battery module respectively and perform detection and diagnosis of a terminal voltage of each battery cell group included in the corresponding battery cell group; and a battery controller which outputs a command to the plurality of integrated circuits and receives a detection result and a diagnosis result of the plurality of integrated circuits, and the battery system has a writable non-volatile memory which stores data indicating usage environments of the battery module including the maximum voltage or the maximum current of the battery module and history data based on usage histories of the battery module.
【課題】電池モジュールの使用経過の監視に基づいて信頼性をより向上させる電池システムを提供。【解決手段】直列に接続された複数の電池セルを有する電池セルグループを、さらに複数個直列に接続して構成した電池モジュールと、電池モジュールの各電池セルグループに対応して設けられ、対応する電池セルグループが有する各電池セルの端子電圧の検出および診断を行う複数の集積回路と、複数の集積回路に指令を出すとともに、該複数の集積回路の検出結果および診断結果を受信するバッテリコントローラと、を有する電池システムにおいて、該電池システムは書き込み可能な不揮発性メモリを有し、該書き込み可能な不揮発性メモリには、電池モジュールの最大電圧あるいは最大電流を含む電池モジュールの使用環境を表すデータと、電池モジュールの使用経過に基づいた履歴データとを保持する。【選択図】図6 |
