An apparatus and method for regulating the charge voltage of a number of electrochemical cells connected in series are disclosed. Equalization circuitry is provided to control the amount of charge current supplied to individual electrochemical cells included within the series string of electrochemical cells without interrupting the flow of charge current through the series string. The equalization circuitry balances the potential of each of the electrochemical cells to within a predetermined voltage setpoint tolerance during charging, and, if necessary, prior to initiating charging. Equalization of cell potentials may be effected toward the end of a charge cycle or throughout the charge cycle. Overcharge protection is also provided for each of the electrochemical cells coupled to the series connection. During a discharge mode of operation in accordance with one embodiment, the equalization circuitry is substantially nonconductive with respect to the flow of discharge current from the series string of electrochemical cells. In accordance with another embodiment, equalization of the series string of cells is effected during a discharge cycle.

L'invention concerne un appareil et un procédé servant à réguler la tension de charge de plusieurs piles électrochimiques branchées en série. Un circuit d'équilibrage sert à réguler le niveau de courant de charge alimentant des piles électrochimiques individuelles comprises dans la série de piles électrochimiques, sans interrompre la circulation du courant de charge à travers ladite série. Ce circuit équilibre le potentiel de chacune des piles électrochimiques en le réglant à un point de tension situé à l'intérieur de tolérances prédéterminées, pendant la charge et, si nécessaire, préalablement au déclenchement de la charge. On peut effectuer l'équilibrage des potentiels des piles vers la fin d'un cycle de charge ou tout au long de ce cycle. Chacune des piles électrochimiques couplée au branchement en série est également protégée contre la surcharge. Pendant un mode de fonctionnement de décharge, selon un mode de réalisation, le circuit d'équilibrage est pratiquement non conducteur par rapport au flux de courant de décharge provenant de la série de piles électrochimiques. Selon un autre mode de réalisation, l'équilibrage de la série de piles est effectué pendant un cycle de décharge.
