CA 2380959

A charging system for an electric device having a plurality of detachable battery units (2, 3, 4), each consisting of a set of storage battery packs (2B, 3B, 4B) and memories (11, 12, 13) storing information about the charge and discharge states of the battery packs. The system provides improved battery charging characteristics and management by using connectors to connect and disconnect an electric device (1) electrically incident to each battery unit being attached or detached. The system includes a driver (9) for driving a load, a charger (5) for charging the storage battery packs (2B, 3B, 4B) by referring to the information stored in the memories (11, 12, 13) of the respective mounted battery units (2, 3, 4), and a controller (6) for controlling the electric power supplied from the individual battery units (2, 3, 4) to the driver (9) by referring to the stored information.

L'invention concerne un dispositif électrique comprenant plusieurs unités (2, 3, 4) d'accumulateurs détachables, consistant chacune en une batterie d'accumulateurs (2B, 3B, 4B) et un dispositif de mémorisation (11, 12, 13) destiné à mémoriser des données concernant les états de charge et de décharge des accumulateurs. Un dispositif de connexion est destiné à connecter et à déconnecter un appareil électrique (1) en réponse au branchement ou au débranchement de chaque unité d'accumulateurs. Le dispositif comprend un organe (9) d'entraînement destiné à entraîner une charge, un chargeur (5) destiné à charger les batteries d'accumulateurs (2B, 3B, 4B) par référence aux données mémorisées dans le dispositif de mémorisation (11, 12, 13) des unités (2, 3, 4) d'accumulateurs montées, et un organe de commande (6) destiné à commander l'énergie fournie par les unités (2, 3, 4) d'accumulateurs individuelles à l'organe (9) d'entraînement par référence aux données antérieures.
