Title
(EN) METHOD FOR MANAGING A NETWORK OF STORAGE BATTERIES AND POWER SUPPLY UNIT OF AN ENGINE
(FR) PROCÉDÉ DE GESTION D'UN RÉSEAU DE BATTERIES D'ACCUMULATEURS ET UNITÉ D'ALIMENTATION ÉLECTRIQUE D'UN MOTEUR
Abstract
(EN) The invention relates to a method for managing a network of storage batteries suitable for supplying electric current to an engine (3) of an electrically propelled motor vehicle (1), said network comprising a first storage battery and at least one second storage battery connected in parallel, each storage battery being connected to a relay which makes it possible to isolate the storage battery from each other storage battery and which is controlled by a computer (10), said method comprising the steps of: - acquiring a state of charge for each storage battery, - determining, by the computer, a control setpoint for each relay as a function of the acquired states of charge, and - controlling said relays on the basis of each determined control setpoint, characterised in that: - in the acquisition step, the computer acquires the value of a first parameter relating to the level of wear of each storage battery, and in that - in the determination step, each control instruction is determined as a function of the value of said first parameter.
(FR) L'invention concerne un procédé de gestion d'un réseau de batteries d'accumulateurs adaptées à alimenter en courant électrique un moteur (3) d'un véhicule automobile (1) à propulsion électrique, ledit réseau comprenant une première batterie d'accumulateurs et au moins une deuxième batterie d'accumulateurs connectées en parallèle, chaque batterie d'accumulateurs étant connectée à un relais qui permet d'isoler la batterie d'accumulateurs de chaque autre batterie d'accumulateurs et qui est piloté par un calculateur (10), ledit procédé comprenant des étapes de : - acquisition pour chaque batterie d'accumulateurs d'un état de charge, - détermination, par le calculateur, d'une consigne de commande de chaque relais en fonction des états de charge acquis, et - pilotage desdits relais sur la base de chaque consigne de commande déterminée, caractérisé en ce que : - à l'étape d'acquisition, le calculateur acquiert la valeur d'un premier paramètre relatif au niveau d'usure de chaque batterie d'accumulateurs, et en ce que - à l'étape de détermination, chaque consigne de commande est déterminée en fonction de la valeur dudit premier paramètre.
