The invention relates to a device for managing battery packs from which it is powered by measuring and monitoring the operating capacity of individual battery modules in a battery pack. A programmable logic controller directs the selective closing of relays to allow individual battery modules to be load-tested using a variable discharge load unit, without compromising useful battery pack capacity. In a further embodiment, the invention can include, for each user, a network of battery management devices with two-way communications links to a central management location with computer based monitoring and control of all battery packs. In addition, a centre of expertise on battery technology is linked to the user networks.

L'invention concerne un dispositif pour gérer des batteries d'alimentation complètes. Ce dispositif, alimenté par ces batteries, permet de mesurer et contrôler la capacité de fonctionnement des modules de batteries individuels dans une batterie complète. Un contrôleur logique programmable dirige la fermeture sélective des relais pour permettre aux modules de batterie individuels de subir des essais de charge à l'aide d'une unité de décharge variable sans compromettre la capacité utile de la batterie. Dans un autre mode de réalisation, l'invention peut comprendre, pour chaque utilisateur, un réseau de dispositifs de gestion de batterie avec des liaisons de communication bidirectionnelles vers un emplacement de gestion centrale et avec un système de surveillance et de commande piloté par ordinateur pour toutes les batteries complètes. En outre, un centre de compétence en matière de technologie des batteries est relié aux réseaux de l'utilisateur.
