Title (EN) VOLTAGE BALANCING CIRCUIT FOR MULTI-CELL MODULES
(FR) CIRCUIT D'EQUILIBRAGE DE TENSION POUR MODULES MULTI-CELLULAIRES
Abstract: front page image
(EN)An energy storage module (100) includes a number of cells (120A, 120B) coupled in series between two end terminals (140, 150), and intermediate terminal (160) or terminals providing access to one or more junctions between individual cells of the module. Voltages of the module's cells are balanced by an intra-module voltage balancer. Two or more such modules are connected in series. To balance voltages of the modules, inter-module voltage balancers (324, 328, 332) are used. In one embodiment, an inter-module voltage balancer is connected to a junction of two modules and to intermediate terminals of the two modules. The inter-module balancer attempts to balance voltages of one or more cells of one of the two modules against one or more cells of the other module. Through operation of the intra-module balancers (130) of each module, voltages of both modules are balanced.
(FR)Un module de stockage d'Energie comprend plusieurs cellules couplEes en sErie entre deux bornes d'extrEmitE et une ou plusieurs bornes intermEdiaires fournissant un accEs A une ou plusieurs jonctions entre des cellules individuelles du module. Les tensions des cellules de module sont EquilibrEes par un Equilibreur de tension intra-module. Deux ou plusieurs modules sont connectEs en sErie. Pour Equilibrer les tensions des modules, des Equilibreurs de tension inter-module sont utilisEs. Dans un mode de rEalisation, un Equilibreur de tension inter-module est connectE A une jonction de deux modules et aux bornes intermEdiaires des deux modules. L'Equilibreur inter-module tente d'Equilibrer les tensions d'une ou plusieurs cellules d'un des deux modules par rapport à une ou plusieurs cellules de l'autre module. Par l'opEration des Equilibreurs intra-module de chaque module, les tensions des deux modules sont EquilibrEes.
