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. Figure pour l'abrégé : Fig. 4Load balancing in an electric battery The present description relates to a system (400) comprising an electric battery (401) of N elementary cells in series (C1, C2, C3, C4), and Z energy transfer modules (M1, M2) having each of the first and second nodes (A, B) connected by K+1 corresponding cells in series, and a third node (D) connected to the first node (A) by only one of the K+1 cells. Each module (M1, M2) has its third node (D) not in common with that of each other module. K is an integer greater than or equal to 2 identical for all modules (M1, M2). A cell (C1) is connected between the first (A) and third nodes (D) of one (M1) of the modules, and to another cell (C2) connected between the first (A) and third (D) nodes d another (M2) of the modules, the third node (D) of said one (M1) of the modules being connected to the first node (A) of said another (M2) of the modules.
