Abstract

L'invention concerne une méthode d’estimation de l’état de santé d’une batterie d’un véhicule électrique ou hybride pouvant être mise en œuvre lors du roulage du véhicule, comprenant : (a) une étape de charge complète, (b) une première étape de relaxation, (c) une étape de décharge jusqu’à un état de charge SOC≤SOCcible, réalisée en k cycles de roulage du véhicule, pour chacun desquels on détermine la capacité Qn déchargée par la batterie, (d) une deuxième étape de relaxation à la fin du cycle k, (e) une étape de détermination d’un état de charge SOCOCV en fonction de la tension en circuit ouvert, (f) une étape de détermination d’une capacité de décharge initiale Qi de la batterie neuve à partir de SOCOCV, et (g) une étape d’estimation de l’état de santé SOH de la batterie à partir de la capacité totale déchargée par la batterie lors de l’étape (c) et de Qi.
