Abstract
【解決手段】複数のセル41a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メインバッテリ41と、メインバッテリ41を充電するメイン充電器と、メインバッテリ41に換えて前記電動モータを駆動するサブバッテリ42と、メインバッテリ41の充電中に、セル41aの電圧Vが所定電圧を超過した分の超過電圧を利用してサブバッテリ42を充電する回生充電器63とを備える。回生充電器63は、セル41a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サブバッテリ42に向けて回生放電する回生放電部64と、回生放電部64により回生放電された電力を制御してサブバッテリ42を充電する充電制御部65とから構成される。
