Claims (1)
- 互いに並列に接続される少なくとも3個のバッテリを放電する車両用バッテリの制御装置であって、
前記各バッテリに充電されている残容量を検出し、前記各残容量に基づいて前記各バッテリを互いの残容量が略同等となるバッテリから構成される複数のバッテリ群に分類する分類手段と、
前記分類手段により前記残容量が最も多いバッテリ群として分類された最大充電量バッテリ群の合計残容量である総残容量を算出するバッテリ群総残容量算出手段と、
前記最大充電量バッテリ群の前記総残容量が前記車両を走行させるために必要最低限の所定容量以上か否かを判定する判定手段と
を含み、
前記判定手段により、前記最大充電量バッテリ群の前記総残容量が前記所定容量以上であると判定されたとき、前記最大充電量バッテリ群を優先使用し、前記最大充電量バッテリ群の前記総残容量が前記所定容量未満であると判定されたとき、前記複数のバッテリ群のうち、各バッテリの残容量が前記最大充電量バッテリ群の各バッテリの残容量よりも小となり、かつ、バッテリ群の合計残容量である総残容量が前記所定容量よりも大となるバッテリ群を優先使用する、ことを特徴とする車両用バッテリの制御装置。
