Summary:To ensure necessary insulation performance with an inexpensive price while making multiple monitoring boards common to each other.SOLUTION: A battery system 1 comprises multiple battery units 10 and multiple monitoring boards 20 each arranged corresponding to each of multiple battery units 10. Each of the multiple monitoring boards 20 includes each of the multiple communication interfaces 21 which are connected in series to an external battery management unit 200. Each monitoring board 20 further includes two low-withstand-voltage insulation components L arranged in the upstream and downstream of the communication interface 21. In a communication line formed by the multiple communication interfaces 21 and the battery management unit 200, an insulation substrate 30 having a high-withstand-voltage insulation component H is provided at the point corresponding to a service plug 40 and between the battery management unit 200 and the communication interface 21 arranged adjacent to the battery management unit 200.SELECTED DRAWING: Figure 1 【課題】複数の監視基板を共通化しつつ、必要な絶縁性能を安価に確保する。【解決手段】電池システム１は、複数の電池ユニット１０と、複数の電池ユニット１０にそれぞれ対応して設けられる複数の監視基板２０とを備える。複数の監視基板２０は、外部の電池管理ユニット２００に対して直列に接続される複数の通信インターフェイス２１をそれぞれ有する。各監視基板２０は、通信インターフェイス２１の上流および下流にそれぞれ配置される２つの低耐圧絶縁部品Ｌをさらに有する。複数の通信インターフェイス２１および電池管理ユニット２００によって形成される通信ラインにおける、サービスプラグ４０に対応する箇所、および電池管理ユニット２００に隣接する通信インターフェイス２１と電池管理ユニット２００との間には、高耐圧絶縁部品Ｈを有する絶縁基板３０が設けられる。【選択図】図１
