Claims (1)
- 複数のセルを電気的に少なくとも直列に接続して構成され、電動モータを駆動するための電力を供給するメインバッテリと、
交流電源から供給される交流電力を直流電力に変換するとともに、変換された直流電圧を制御して前記メインバッテリを充電する充電制御手段と、
前記メインバッテリに換えて前記電動モータを駆動するための電力を供給可能なサブバッテリと、
前記充電制御手段による前記メインバッテリの充電中に、前記セルに充電されたセル電圧が所定電圧を超過した分の超過電圧を利用して前記サブバッテリを充電する回生充電制御手段とを備え、
前記回生充電制御手段は、
前記セルの正負両極間に接続され、前記超過電圧に基づいて入力される余剰電力を変圧するとともに前記サブバッテリに向けて回生放電する回生放電部と、
前記回生放電部により回生放電された電力を制御して前記サブバッテリを充電する充電制御部とを備えて構成され、
前記回生放電部は、直列に接続された複数の前記セルにそれぞれ設けられるとともに、他の前記回生放電部と電気的もしくは光学的に接続されて各々の前記セルの充電状況を通信可能であり、各々の前記セルにおける前記セル電圧のバラツキを監視するように構成され、前記セル電圧のバラツキが所定範囲よりも大きいときには、前記余剰電力を前記回生放電し、前記セル電圧のバラツキが前記所定範囲内のときには、前記余剰電力を放電抵抗により放熱することを特徴とする充電システム。
