Description
本発明の電池監視装置10の一実施形態について図1〜図2を参照して説明する。図1は、本発明の電池監視装置10の一実施形態を示す斜視図である。図2は、図1に示す電池監視装置10の電気構成図である。電池監視装置10は、図示しない車両に搭載された電池パック20の状態を監視する装置である。このような車両は、ハイブリッドカーや電気自動車などの電動モータからの駆動力により走行する車両である。電池パック20は、この車両に搭載された電動モータに電源を供給する。
次に、第2実施形態の電池監視装置10について説明する。第1実施形態と第2実施形態とで大きく異なる点は、第1実施形態では、ECU123が中継を指示していたが、第2実施形態では、検出用基板101〜10nがECU基板120と直接通信できるか否かを判断し、中継を指示するようにしてもよい。直接通信できるか否かの判断としては、例えば、検出用基板101〜10nから計測値を送信したときに、ECU基板120から受信完了通知(ACK)を受信できるか否かによって判断できる。
20 電池パック
101〜10n 検出用基板(検出部)
110 電圧計測回路(検出回路)
112 第1無線回路
120 ECU基板(監視部)
121、122 第2無線回路
201〜20n 電池モジュール
