Title (EN) A BILEVEL EQUALIZER FOR BATTERY CELL CHARGE MANAGEMENT
(FR) ÉGALISEUR À DEUX NIVEAUX POUR GESTION DE CHARGE D'ÉLÉMENT DE BATTERIE
Abstract:
(EN) An equalizer circuit provides both passive and active charge transfer between cells in a battery pack to improve charge and discharge efficiency. The equalizer circuit is a bilevel circuit that uses both resistive equalizers and switching equalizers to balance cell charge. The cells may be grouped into size limited sections which are balanced by resistive equalizers. The sections are balanced by switching equalizers to promote increased pack discharge capacity.
(FR) La présente invention porte sur un circuit égaliseur qui fournit à la fois un transfert de charge passif et actif entre des éléments d'un bloc-batterie pour améliorer le rendement de charge et décharge. Le circuit égaliseur est un circuit à deux niveaux qui utilise à la fois des égaliseurs résistifs et des égaliseurs de commutation pour équilibrer la charge d'élément. Les éléments peuvent être groupés en sections de dimension limitée qui sont équilibrées par des égaliseurs résistifs. Les sections sont équilibrées par des égaliseurs de commutation pour favoriser la capacité de décharge de bloc accrue.
