Title (EN) FUEL CELL HYBRID POWER SYSTEM
(FR) SYSTÈME D'ALIMENTATION HYBRIDE À PILE À COMBUSTIBLE
Abstract:
(EN) A power system comprising: an electrical power bus; one or more loads (20) electrically coupled to the electrical power bus; a fuel cell (10); a DC-DC converter (14) electrically coupled between the fuel cell (10) and the electrical power bus; a battery (34); a switch (38) electrically coupled between the battery (34) and the electrical power bus; and a power system manager (22) configured to control operation of the switch (38); wherein the switch (38) is switchable between a first state and a second state; the first state of the switch (38) is such that the battery (34) is directly connected to the electrical power bus such that the battery (34) provides electrical power directly to the electrical power bus; and the second state of the switch (38) is such that the battery (34) is disconnected from the electrical power bus.
(FR) L'invention concerne un système d'alimentation comprenant : un bus d'alimentation électrique ; une ou plusieurs charges (10) couplées électriquement au bus d'alimentation électrique ; une pile à combustible (10) ; un convertisseur courant continu/courant continu (14) couplé électriquement entre la pile à combustible (10) et le bus d'alimentation électrique ; une batterie (34) ; un commutateur (38) électriquement couplé entre la batterie (34) et le bus d'alimentation électrique ; et un gestionnaire de système d'alimentation (22) configuré pour commander le fonctionnement du commutateur (38) ; le commutateur (38) étant commutable entre un premier état et un second état ; le premier état du commutateur (38) étant tel que la batterie (34) est directement connectée au bus d'alimentation électrique de sorte que la batterie (34) fournisse de l'énergie électrique directement au bus d'alimentation électrique ; et le second état du commutateur (38) étant tel que la batterie (34) est déconnectée du bus d'alimentation électrique.
