Title
(EN) RECHARGEABLE BATTERY SYSTEM FOR A VEHICLE
(FR) SYSTEME DE BATTERIE RECHARGEABLE POUR UN VEHICULE
Abstract
(EN)
The invention relates to a rechargeable battery system (100) for a vehicle, the system comprising at least two sub-systems of batteries (200, 300), each provided with two connection terminals, control means (50, 41-49), at least one recharging interface (60), and at least one consumption interface (63), the control means (50, 41-49), being suitable for connecting in parallel the terminals of said at least two sub-systems of batteries (200, 300) to the recharging interface (60) while the battery system is recharging, and to the consumption interface (63). According to the invention, the control means are further suitable for connecting in a series the terminals of said at least two sub-systems of batteries (200, 300) to the recharging interface (60), when a recharge of the battery system by the recharging interface is controlled at a second determined recharging voltage, and to the consumption interface (63) in order to provide a second determined supply voltage.

L'invention concerne un système de batterie rechargeable (100) pour un véhicule, le système comprenant au moins deux sous-systèmes de batteries (200, 300) pourvus chacun de deux bornes de connexion, des moyens de commande (50, 41-49), au moins une interface de recharge (60) et au moins une interface consommatrice (63), les moyens de commande (50, 41-49) étant aptes à connecter en parallèle les bornes desdits au moins deux sous-systèmes de batterie (200, 300) à l'interface de recharge (60) lors d'une recharge du système de batterie et à l'interface consommatrice (63). Selon l'invention, les moyens de commande sont aptes en outre à connecter en série les bornes desdits au moins deux sous-systèmes de batterie (200, 300) à l'interface de recharge (60) lorsqu'une recharge du système de batterie par l'interface de recharge est commandée à une deuxième tension de recharge déterminée et à l'interface consommatrice (63) pour fournir une deuxième tension d'alimentation déterminée.
