Abstract
Description
図1は、この開示の実施の形態に係る充電システムの全体構成を概略的に示す図である。図1を参照して、この実施の形態における充電システムは、車両1と、サーバ200と、充電スタンド300と、通信ネットワーク900とを含む。車両1は、プラグインハイブリッド車両である。しかし、本開示に係る車両1は、プラグインハイブリッド車両に限定されず、電気自動車または燃料電池車であってもよい。
(1) 前述した実施の形態においては、図6で示したように、SOC領域を2段階に分けて、SOC領域ごとに充電電流を切替えるようにした。しかし、これに限定されず、SOC領域を2以上の多段階に分けて、SOC領域ごとに充電電流を切替えるようにしてもよい。また、SOCの増加に応じて徐々に充電電流を増加させるようにしてもよい。
(1) 図1で示したように、バッテリ10の充電方法は、車両1に搭載されたリチウムイオン二次電池であるバッテリ10を車両1の外部の充電スタンド300から供給される電力により充電する充電方法である。図3で示したように、充電方法は、バッテリ10のSOCが低い領域ほどバッテリの抵抗値が高くなる傾向を示すバッテリ10のSOCと抵抗値との間の相関関係を車両の走行時に取得するステップ(ステップS111〜ステップS112)と、バッテリ10の負極への金属リチウムの析出を抑制可能な充電電流を相関関係に基づいてバッテリ10のSOC領域ごとに決定するステップ(ステップS113〜ステップS119)とを含む。これにより、ハイレート劣化が起こりにくくすることができる。
Claims (1)
- 車両に搭載されたリチウムイオン二次電池であるバッテリを前記車両の外部から供給される電力により充電する、前記バッテリの充電方法であって、
前記バッテリのSOCが低い領域ほど前記バッテリの抵抗値が高くなる傾向を示す前記バッテリのSOCと抵抗値との間の相関関係を前記車両の走行時に取得するステップと、
前記バッテリの負極への金属リチウムの析出を抑制可能な充電電流を前記相関関係に基づいて前記バッテリのSOC領域ごとに決定するステップとを含む、バッテリの充電方法。
