Abstract
Description
図1は、本発明が適用されるハイブリッド車両1の構成を示すブロック図である。図1を参照して、ハイブリッド車両1は、エンジン10と、モータジェネレータ20,30と、動力分割機構40と、リダクション機構58と、駆動輪62と、パワーコントロールユニット(PCU)60と、バッテリ70と、電圧センサ71と、電流センサ72と、制御装置80とを含む。
上記の車両において、バッテリ70と電圧センサ71と電流センサ72と制御装置80とによって、車両の電源装置が構成される。以下、車両の電源装置において実行されるバッテリ70の充放電制御についてより詳細に説明する。
以下の説明において「電流センサ72の検出値」は、電流センサ72の出力を補正せずに電流に変換した値を示し、「電流センサ72の制御電流値」は、電流センサ72の検出値に対して制御装置80内に記憶されているオフセット補正値を上式のとおり減算した補正後の電流値を示すこととする。
A1) オフセット補正許可から累積時間(たとえば3600秒)以上が経過。
A2) オフセット補正を許可している間に、電池パック内の電池セル電圧の最大値が、所定電圧以上である状態が所定時間以上連続した。
A3) 今回のトリップ中にオフセット補正が禁止された(オフセット補正禁止フラグがONに設定されている)。
A11) 所定の検知期間において電流センサの制御電流値(電流IB)の積算値が所定値以上である。
A12) 所定の検知期間においてSOCが所定量以上低下した。
B1) 現在オフセット補正を許可しておらず(オフセット補正許可フラグ=OFF)、かつオフセット補正が禁止されていない(オフセット補正禁止フラグ=OFF)。
B2) バッテリからの許容出力電力Woutが所定値以下である。
B3) バッテリへの許容入力電力Winが所定値以上である(ただし、Winは負の値で表される)。
B4) 電圧推定SOCが初期のSOC基準値(図4の例ではA(%))以下である。
B5) バッテリパック内のセル温度の最低値が所定値以下である。
なお、上式のオフセット補正値には、際限なくオフセット補正量が拡大するのを防ぐため、上限値を設けておいても良い。
[変形例]
なお、以上の実施の形態では、バッテリ70のSOCが下限値付近であり、過放電の虞がある場合に実行される電流センサ72のオフセット補正について説明した。同様なやり方で、バッテリ70のSOCが上限値付近であり、過充電の虞がある場合に電流センサ72のオフセット補正を実行しても良い。
