Abstract
Description
<二次電池システムの構成>
図1は、本実施の形態に係る二次電池システムが搭載されたハイブリッド車の全体構成を概略的に示す図である。図1を参照して、車両1は、二次電池システム2と、ソーラーパネル200と、ソーラーバッテリ300と、補機バッテリ400と、モータジェネレータ510,520と、エンジン530と、動力分割装置540と、駆動軸550と、駆動輪560とを備える。二次電池システム2は、バッテリ10と、システムメインリレー(SMR:System Main Relay)20と、充電リレー30と、パワーコントロールユニット(PCU:Power Control Unit)40と、ソーラーPCU50と、電子制御装置(ECU:Electronic Control Unit)100とを備える。
二次電池のSOC推定手法としては以下のような手法が公知である。すなわち、まず、二次電池に設けられた電圧センサおよび電流センサの検出結果に基づいて、二次電池のOCVが取得される。たとえば、無負荷状態(電流=0)が所定期間継続したことが電流センサにより検出された場合に、その状態での電圧センサの検出値をOCVとして取得することができる。そして、OCVとSOCとの関係を示す特性曲線(OCV−SOCカーブ)を参照することによって、OCVからSOCが推定される。
ヒステリシスを解消するためのバッテリ10への充電電力量と、SOCの推定精度との間には、相関関係が存在する。したがって、バッテリ10への充電電力量は、充電電力量とSOC推定誤差(あるいは推定精度)との関係を事前に求めることによって、予め決定することができる。
最後に、バッテリ10のSOCを推定する制御(SOC推定制御)について説明する。本実施の形態においては、前述のように、バッテリ10への充電によりヒステリシスが解消され、その後にバッテリ10のSOCが推定される。
