An apparatus for cell balancing of a battery module, in which a first battery cell, a plurality of second battery cells, and a third battery cell are connected in series, is provided. A first terminal of a first inductor is connected to a negative electrode of the first battery cell, and a first terminal of a second inductor is connected to a positive electrode of the third battery cell. A first transistor is connected between a second terminal of the first inductor and a second terminal of the second inductor. A first active element is connected between a positive electrode of the first battery cell and the second terminal of the first inductor, and a second active element is connected between a negative electrode of the third battery cell and the second terminal of the second inductor.
La présente invention concerne un appareil d'équilibrage de cellules d'un module de batterie, dans lequel une première cellule de batterie, une pluralité de deuxièmes cellules de batterie et une troisième cellule de batterie sont raccordées en série. Une première borne d'une première bobine d'induction est raccordée à une électrode négative de la première cellule de batterie et une première borne d'une seconde bobine d'induction est raccordée à une électrode positive de la troisième cellule de batterie. Un premier transistor est raccordé entre une seconde borne de la première bobine d'induction et une seconde borne de la seconde bobine d'induction. Un premier élément actif est raccordé entre une électrode positive de la première cellule de batterie et la seconde borne de la première bobine d'induction et un second élément actif est raccordé entre une électrode négative de la troisième cellule de batterie et la seconde borne de la seconde bobine d'induction.
