Title
(EN) CONFIGURABLE BATTERY PACK FOR FAST CHARGE
(FR) BLOC-BATTERIE CONFIGURABLE POUR CHARGE RAPIDE
Abstract
(EN) A configurable battery system may be arranged in such a way that two battery modules are connected in parallel to achieve a target maximum voltage for a load, or in series to achieve a high voltage of about double the target maximum voltage. Fast charging, at high voltage, may allow both battery modules to be charged at a charging current near a desired maximum current at the battery charger. A battery management module determines a switch configuration, coupling the battery modules in series or parallel. The battery management module applies the switch configuration to one or more switches to manage charging of the battery modules. The battery management module may receive charger capability information, local charging information, and fault information to aid in determining a switch configuration.
(FR) L'invention concerne un système de batterie configurable pouvant être agencé de sorte que deux modules de batterie soient connectés en parallèle pour obtenir une tension maximale cible pour une charge, ou en série pour obtenir une tension élevée d'environ le double de la tension maximale cible. Une charge rapide, à haute tension, peut permettre la charge des deux modules de batterie à un courant de charge proche d'un courant maximal souhaité au niveau du chargeur de batterie. Un module de gestion de batterie détermine une configuration de commutateur, couplant les modules de batterie en série ou en parallèle. Le module de gestion de batterie applique la configuration de commutation à un ou plusieurs commutateur(s) pour gérer la charge des modules de batterie. Le module de gestion de batterie peut recevoir une information de capacité de chargeur, des informations de charge locale et des informations de défaillance pour aider à déterminer une configuration de commutateur.
