Abstract
Description
図面を参照しながら実施形態に係る電源回路100のセンサユニット1について説明する。図1は、実施形態に係る電源回路100の構成例を示すブロック図である。図2は、実施形態に係るセンサユニット1の構成例を示すブロック図である。図3は、比較例に係る電力演算例を示す図である。図4は、実施形態に係る電力演算例を示す図である。図5は、実施形態に係る高電圧電池101の劣化状態の第1判定例を示す図である。図6は、実施形態に係る高電圧電池101の劣化状態の第2判定例を示す図である。
次に、実施形態の変形例について説明する。変形例では、実施形態と同等の構成要素には同一の符号を付し、その詳細な説明を省略する。図7は、実施形態の第1変形例に係るセンサユニット1Aの構成例を示すブロック図である。第1変形例に係るセンサユニット1Aは、制御部60Aがセンサユニット1A内に含まれない点で実施形態に係るセンサユニット1とは異なる。センサユニット1Aは、図7に示すように、基板10と、端子部40と、センサ部50とを有する。センサユニット1Aは、コネクタCNを介して外部の制御部60A(他ECU)に接続される。制御部60Aは、センサ部50により検出された検出結果に基づいて各種演算を行う。このように、センサユニット1Aは、制御部60Aがセンサユニット1Aに含まれずに外部に配置されてもよい。
