Abstract

La présente invention relève du domaine du génie électrique et peut être utilisée pour la régénération de différents types de batteries d'accumulateurs. Le procédé de régénération de cette invention consiste d'abord à obtenir, en chargeant la batterie d'accumulateurs, des valeurs définies des paramètres du processus technologique de régénération, puis à charger la batterie d'accumulateurs en faisant passer à travers ladite batterie d'accumulateurs une succession d'impulsions rectangulaires de courant dont la durée est comprise entre 150 et 600 μs, un intervalle de 2 à 6 secondes séparant chaque impulsion, à une amplitude constante ou réduite selon, respectivement, que la température est inférieure ou supérieure à une valeur donnée. Une fois la charge de la batterie d'accumulateurs terminée, le procédé consiste ensuite à mesurer la capacité de la batterie d'accumulateurs au moyen d'une décharge jusqu'à la valeur admissible de la tension. Le cycle de régénération est répété si la capacité de la batterie est inférieure à 80% de la valeur nominale. Le dispositif de cette invention comprend un ensemble de sources de courant de charge, un capteur de courant, un capteur de tension, un capteur de température, une unité de mesure de la densité de l'électrolyte, une unité de mémoire, une unité de couplage, une unité d'identification, un processeur et un décodeur. Cette invention permet d'augmenter l'efficacité de régénération de la capacité de la batterie d'accumulateurs.
