Abstract
Description
図1は、第1実施形態の電池監視装置51及びその周辺を示す回路図である。車両は、動力スイッチ70と組電池60と補機バッテリ67と電池監視装置51とを有し、さらに電源線31,38と検出線39とが設けられている。組電池60は、複数の単位電池63を有する。複数の単位電池63は、複数の電池ブロック62にグループ分けされている。電池監視装置51は、電池ECU10と、複数の電圧モニタ20とを有する。
次に、第2実施形態の電池監視装置52について説明する。なお、以下の実施形態では、それ以前の実施形態のものと同一の又は対応する部材等は、同一の符号を付する。ただし、電池監視装置自体については、実施形態毎に異なる符号を付する。本実施形態については、第1実施形態をベースにそれと異なる点を中心に説明する。
図6は、第3実施形態の電池監視装置53を示す回路図である。本実施形態については、第1実施形態をベースにそれと異なる点を中心に説明する。親機16が電源スイッチ16aを備えておらず、常に親機16に電力が供給されるようになっている。そのため、電池ECU10は、動力スイッチ70がOFFになっても、MCU13の電源スイッチ13aがOFFになるのみで、親機16及び記憶部17は起動し続ける。
次に第4実施形態の電池監視装置54について説明する。第4実施形態については、第3実施形態をベースにそれと異なる点を中心に説明する。
次に第5実施形態の電池監視装置55について説明する。本実施形態については、第3実施形態をベースにそれと異なる点を中心に説明する。
次に第6実施形態の電池監視装置56について説明する。本実施形態については、第5実施形態をベースにそれと異なる点を中心に説明する。第1通信モードM1については、第5実施形態の場合と同様である。よって、第1通信モードM1では、親機16が各子機26に対して個別に信号を送信する個別通信を行う。
以上の実施形態は、次のように変更して実施することもできる。例えば、記憶部17,27に記憶する電圧モニタ情報を、上記の数情報、位置情報及び周期情報のうちのいずれか1つ又は2つのみに基づくものにしてもよい。具体的には、電圧モニタ情報を、少なくとも数情報に基づくものにしてよい。また、電圧モニタ情報を、少なくとも位置情報に基づくものにしてもよい。また、電圧モニタ情報を、少なくとも周期情報に基づくものにしてもよい。また、電圧モニタ情報を、少なくとも数情報及び位置情報に基づくものにしてもよい。また、電圧モニタ情報を、少なくとも数情報及び周期情報に基づくものにしてよい。また、電圧モニタ情報を、少なくとも位置情報及び周期情報に基づくものにしてもよい。
