Title
(EN) HYBRID POWER SUPPLY DEVICE
(FR) DISPOSITIF D'ALIMENTATION ELECTRIQUE HYBRIDE
Abstract
(EN)
A hybrid power supply device for charging a secondary battery (4) by a fuel cell (3) and supplying power from the secondary battery (4) to a load (1), wherein each unit secondary battery (4a) constituting the secondary battery (4) is properly charged without excessive charging even when variations in remaining capacity occur among unit secondary batteries (4a). The fuel cell (3) is divided into a plurality of unit fuel cells (3a) each consisting of a specified number of cells, and each unit fuel cell (3a) is parallel-connected with each unit secondary battery (4a) via each charging switch (13) to constitute each unit hybrid power supply (2a). A charging switch (13) is controlled for each unit hybrid power supply (2a) based on the remaining capacity of each unit secondary battery (4a) to permit a unit fuel cell (3a) to charge a unit secondary battery (4a).
(FR)
L'invention porte sur un dispositif d'alimentation électrique hybride destiné à mettre en charge une batterie secondaire (4) par une pile à combustible (3) et envoyer le courant de la batterie secondaire (4) à une charge (1). Chaque batterie secondaire unitaire (4a) constituant la batterie secondaire (4) est mise en charge correctement sans charge excessive même si la capacité restante varie dans les batteries secondaires unitaires (4a). La pile à combustible (3) est divisée en une pluralité de piles à combustibles unitaires (3a) constituant chacune un nombre spécifique de piles, et chaque pile à combustible unitaire (3a) est raccordée parallèle à chaque batterie secondaire unitaire (4a) via chaque commutateur de mise en charge (13) afin de constituer chaque alimentation électrique hybride unitaire (2a). Un commutateur de mise en charge (13) est commandé pour chaque alimentation électrique hybride unitaire (2a) en fonction de la capacité restante de chaque batterie secondaire unitaire de sorte qu'une pile à combustible unitaire (3a) puisse charger une batterie secondaire unitaire (4a).
