Abstract

Equilibrage de charge dans une batterie électrique La présente description concerne un système (400) comprenant une batterie électrique (401) de N cellules élémentaires en série (C1, C2, C3, C4), et Z modules de transfert d'énergie (M1, M2) ayant chacun des premier et deuxième noeuds (A, B) reliés par K+1 cellules correspondantes en série, et un troisième noeud (D) relié au premier noeud (A) par une seule des K+1 cellules. Chaque module (M1, M2) a son troisième noeud (D) non commun avec celui de chaque autre module. K est un entier supérieur ou égal à 2 identique pour tous les modules (M1, M2). Une cellule (C1) est connectée entre les premier (A) et troisième noeuds (D) d'un (M1) des modules, et à une autre cellule (C2) connectée entre les premier (A) et troisième (D) noeuds d'un autre (M2) des modules, le troisième noeud (D) dudit un (M1) des modules étant connecté au premier noeud (A) dudit un autre (M2) des modules.
