CA 2531365

The invention relates to a method and a device for supplying at least one load consumer (3) during a mains failure. According to said method, a plurality of batteries (4.5) acts as an emergency voltage source during the failure of a mains voltage source (2) in order to supply the load consumer(s). The plurality of batteries is connected to the mains voltage source. The batteries are interconnected in series in order to form the emergency supply for the load consumer. To permit a simple, cost-effective emergency supply with a reliable charging of the batteries, the plurality of series-connected batteries is sub-divided into at least two battery groups using a splitter circuit (9) and each of said battery groups is connected to the mains voltage source for charging purposes by means of a corresponding connection circuit (10).

Procédé et dispositif d'alimentation d'au moins une charge en cas de panne de secteur. Selon ce procédé, ladite charge au moins est alimentée par une pluralité de batteries, en tant que source de tension de secours, en cas de défaillance de la source de tension de secteur. La pluralité de batterie est connectée à la source de tension de secteur. Les batteries sont connectées les unes aux autres en série pour l'alimentation de secours de la charge. Selon la présente invention, pour permettre une alimentation de secours simple et peu onéreuse, ainsi qu'une charge fiable des batteries, la pluralité de batteries connectées en rangée est divisée en au moins deux groupes de batteries à l'aide d'un circuit de répartition et chacun des groupes de batteries est connecté à la source de tension de secteur, en vue de sa charge, par l'intermédiaire d'un circuit de connexion correspondant.
