Method for power increase control for fuel cell in motor vehicle, uses heat released from connected batteries to heat disconnected batteries prior to reconnection

The method for power increase control in a motor vehicle (V) fuel cell (1) involves adjustment of each battery (3a-c) which is disconnected in a temperature range for optimum functioning of the fuel battery. The battery is then connected to the drive motor circuit. This stage is repeated for all of...

description	The method for power increase control in a motor vehicle (V) fuel cell (1) involves adjustment of each battery (3a-c) which is disconnected in a temperature range for optimum functioning of the fuel battery. The battery is then connected to the drive motor circuit. This stage is repeated for all of the battery cells in the drive. Heat released from the connected batteries is used to heat the disconnected cells. Alternatively, an external heat source is used. Claims include a control using the method. La présente invention concerne un procédé de gestion de la montée en puissance disponible d'une pile à combustible insérée dans un circuit d'alimentation en énergie électrique d'au moins un consommateur d'un véhicule automobile, notamment d'un moteur électrique de propulsion dudit véhicule, la pile à combustible comportant au moins deux éléments de pile branchés en parallèle et aptes à être connectés sélectivement au circuit d'alimentation électrique. Ce procédé est remarquable en ce que, successivement pour chacun d'une pluralité d'éléments de pile déconnectés électriquement du circuit, on procède selon les étapes suivantes : a) ajustement de la température de l'élément de pile déconnecté dans une plage de températures de fonctionnement optimal de cet élément de pile; b) connexion électrique au circuit (7) de l'élément de pile.
