Patent number: 9649951Abstract: An automotive vehicle drive unit, comprising a fuel cell whose control input is a setpoint of the electrical power to be delivered by the fuel cell. There is a reversible electrical energy storage system and an electric motor to propel the wheels of a vehicle. An electrical connection element selectively connects the fuel cell and/or the energy storage system to the electric motor. A control circuit stores a model of the consumption of dihydrogen as a function of the power delivered by this fuel cell, in the form of a second-degree polynomial and is configured to compute a coefficient of power distribution ?1 between the fuel cell and the electrical energy storage system pursuant to a defined equation. The control circuit controls the electrical connection element to recharge the energy storage system when the value of the power setpoint Pfc* is greater than the power demanded by the electric motor.Type: GrantFiled: July 11, 2013Date of Patent: May 16, 2017Assignees: Commissariat à l'énergie atomique et aux énergies alternatives, Institut National des Sciences Appliquées de Lyon, Centre National de la Recherche Scientifique, Université Lyon 1 Claude Bernard, Ecole Centrale De Lyon, Institut Français des Sciences et Technologies des Transports RéseauxInventors: Mathias Gerard, Eric Bideaux, Ramon Da Fonseca, Matthieu Desbois-Renaudin, Bruno Jeanneret
