An ECU estimates an output allowable power of a power storage device based on the temperature and SOC of the power storage device. The ECU also calculates a threshold power based on the power required to start an engine. When the ECU determines that the output allowable power is lower than the threshold power, the up-converter is controlled such that the boosting rate of the up-converter is restricted to be below a prescribed value.

La présente invention concerne un bloc de commande électronique (ECU) effectuant l'estimation d'une énergie de sortie (Pmax) qui peut être produite par un dispositif d'accumulation en fonction d'une température et de l'état de charge d'un dispositif d'accumulation (B) (S40). L'ECU calcule également une énergie seuil (Pth) en fonction de l'énergie requise pour le démarrage du moteur (S50). Lorsque l'ECU détermine que l'énergie de sortie (Pmax) est inférieure à une énergie seuil (Pth) (Oui en S60), l'ECU commande un convertisseur-survolteur (S70) afin de limiter le rapport de survoltage du convertisseur-survolteur en dessous d'une valeur prédéterminée.
