Description
ちなみに、一般的な小型自動車のバッテリ(鉛蓄電池)はSOCが100〜90%程度で使用される。ハイブリッド車用ニッケル水素電池ではSOCが75〜25%程度、電気自動車(EX)用のリチウムイオン電池では90〜10%程度あるいは80〜30%程度のSOCで使用される。
このようなSOCの範囲で繰り返し充電して電動車を使用することが、バッテリ/電池のサイクル寿命を延ばす上で重要とされている。
この場合には、充電中の冷却のことも加味し、より無駄のないタイミングで駆動用バッテリ1の冷却を開始できる。
これにより、冷房機能≒キャビンの商品性とのバランスを考慮してバッテリ1のプレクーリングを実施することが可能になる。
これにより、空調用冷凍サイクルの機能を用いることによってバッテリ冷却目標温度が環境温度よりも低い場合であっても駆動用バッテリ1を冷却することが可能になる。
これにより、さらに冷房機能≒キャビンの商品性とのバランスを考慮したバッテリ1のプレクーリングを実現できる。
