Abstract
Description
以下、電源装置100の制御について図2を参照して説明する。通常制御時において、各電池モジュール102(102a,102b,・・・102n)のAND素子22に対して制御コントローラ104からハイ(H)レベルの強制切断信号が入力される。したがって、第1スイッチ素子16のゲート端子には遅延回路20からの出力信号がNOT素子24を介して反転信号として入力され、第2スイッチ素子18のゲート端子には遅延回路20からの出力信号がそのまま入力される。
図5は、本実施の形態における電池モジュール102の内部抵抗測定処理のフローチャートを示す。以下、図5を参照して、電池モジュール102の内部抵抗測定処理について説明する。
