Abstract
【解決手段】外部電源200の電力によるバッテリ10の外部充電時において、補機負荷80,90の作動パターンを層別して、バッテリ10の充電電力の実績値が学習される。タイマー充電のスケジュール作成時において、充電所要時間は、外部充電中において時刻ベースで制御される補機負荷80,90の作動スケジュールに従った各作動パターンの実行時間と、各作動パターンでの充電電力学習値と、外部充電前のSOCから求められる満充電状態までの総充電電力量とに基づいて推定される。推定された充電所要時間に従って、タイマー充電による充電終了時刻から遡って外部充電の開始時刻が設定される。
【選択図】図1
Description
車両100は、電力線15に接続された高圧系の補機負荷80と、電源配線85に接続された低圧系の補機負荷90とをさらに含む。電源配線85は、補機バッテリ84と接続されて、低圧系の補機負荷90の電源電圧(たとえば、12V)を供給する。
(1)中において、PLN♯は更新前の学習値であり、係数αは学習速度を調整するための、0<α<1に設定されるパラメータである。α=0とすると、学習値は更新されず、α=1とすると、今回の充電電力実績値Pchが、そのまま充電電力学習値PLNに採用される(PLN=Pch)。
図12には、充電電力学習部120における充電電力学習における学習テーブル設定の変形例を説明する概念図が示される。
