A battery ages and wears out less quickly when the same is charged to a high degree. Furthermore, acid layers form on batteries primarily under the effect of gravity on the electrolyte, resulting in a significant reduction of the capacity of the battery. The invention relates to a method and an arrangement for modifying the state of charge and the state of health of batteries, in which a separate electric current (i) is applied individually to at least one cell (Z) of the multicell battery (1), said current (i) being superimposed on an operating current (iA) while acting upon said at least one cell (Z) in order to charge or discharge said cell (Z).
Un état de charge élevé entraîne un vieillissement et une usure réduits d'un accumulateur. Par ailleurs, l'effet de la gravité sur l'électrolyte provoque la formation de couches d'acide dans un accumulateur, entraînant une réduction considérable de la capacité de l'accumulateur. L'invention concerne un procédé et un dispositif de modification de l'état de charge et d'usure d'accumulateurs. Selon l'invention, au moins une cellule (Z) de l'accumulateur multi-cellules (1) reçoit individuellement un courant électrique séparé (i), ce courant (i) est superposé à un courant de travail (iA), et agit enfin sur la ou les cellules (Z) pour le chargement ou le déchargement de cette cellule (Z).
