Abstract
(EN) A conversion device (10) is used in a power supply system in which a plurality of batteries (34A, 34B) may be connected at least in parallel. The conversion device (10) includes a power conversion unit (40). The power conversion unit (40) performs a first conversion operation of converting power inputted from the batteries (34A, 34B) and outputting power to a conductive path different from the batteries (34A, 34B). The power conversion unit (40) performs a second conversion operation of outputting power individually to at least any of the batteries (34A, 34B).
(FR) La présente invention concerne un dispositif de conversion (10) utilisé dans un système d'alimentation électrique dans lequel une pluralité de batteries (34A, 34B) peuvent être connectées au moins en parallèle. Le dispositif de conversion (10) comprend une unité de conversion de puissance (40). L'unité de conversion de puissance (40) effectue une première opération de conversion de la puissance fournie par les batteries (34A, 34B) et délivre de l'énergie à un trajet conducteur différent des batteries (34A, 34B). L'unité de conversion de puissance (40) effectue une seconde opération de conversion consistant à délivrer de l'énergie individuellement à au moins l'une quelconque des batteries (34A, 34B).
(JA) 変換装置(10)は、複数のバッテリ(34A,34B)が少なくとも並列に接続され得る電源システムに用いられる。変換装置(10)は、電力変換部(40)を有する。電力変換部(40)は、バッテリ(34A,34B)から入力される電力を変換し、バッテリ(34A,34B)とは異なる導電路に電力を出力する第1変換動作を行う。電力変換部(40)は、少なくともいずれかのバッテリ(34A,34B)に対して個別に電力を出力する第2変換動作を行う。
