When a constant voltage is required of a power supply circuit (31) that has a main battery (32) connected thereto and permits connection of a sub-battery (33) having an internal resistance lower than that of the main battery (32), the present invention switches between the connection and disconnection of the sub-battery (33) to and from the power supply circuit (31) in accordance with the required constant voltage, the maximum current that can be output to the power supply circuit (31) by an alternator (24), and the state of charge of the sub-battery (33).

    L'invention concerne, lorsqu'une tension constante est requise d'un circuit d'alimentation en énergie (31) auquel est connectée une batterie principale (32) et qui permet la connexion d'une batterie secondaire (33) ayant une résistance interne inférieure à celle de la batterie principale (32), la commutation entre la connexion et la déconnexion de la batterie secondaire (33) au circuit d'alimentation en énergie (31) conformément à la tension constante requise, au courant maximal pouvant être délivré en sortie vers le circuit d'alimentation en énergie (31) par un alternateur (24) et à l'état de charge de la batterie secondaire (33).
