Title
(EN) SYSTEMS AND METHODS FOR POWER SHARING CONTROL FOR DIRECT INTEGRATION OF FUEL CELLS IN A DUAL-INVERTER EV DRIVETRAIN
(FR) SYSTÈMES ET PROCÉDÉS DE COMMANDE DE PARTAGE DE PUISSANCE POUR L'INTÉGRATION DIRECTE DE PILES À COMBUSTIBLE DANS UNE TRANSMISSION DE VÉHICULE ÉLECTRIQUE À DOUBLE ONDULEUR
Abstract
(EN) A dual inverter drivetrain having an energy storing fuel cell integrated into an electric vehicle is disclosed. A method of operating the dual inverter drivetrain using a power sharing control approach is described, which allows the key requirements of a fuel cell to be achieved without compromising the dynamic performance of the electric vehicle drive system. In particular, the ability of this control approach to ensure unidirectional power transfer from the fuel cell even in the event of regenerative braking, and a slowly changing fuel cell power despite fast motor torque transients were exhibited.
(FR) La présente invention concerne une transmission à double onduleur présentant une pile à combustible à stockage d'énergie intégrée dans un véhicule électrique. L'invention concerne également un procédé de fonctionnement de la transmission à double onduleur utilisant une approche de commande de partage de puissance, ce qui permet d'obtenir les exigences clés d'une pile à combustible sans compromettre la performance dynamique du système d'entraînement de véhicule électrique. En particulier, la capacité de cette approche de commande à assurer un transfert de puissance unidirectionnel à partir de la pile à combustible même en cas de freinage régénératif et une puissance de pile à combustible à changement lent malgré des transitoires de couple moteur rapides ont été démontrées.
