Abstract

La présente invention concerne un système de charge de batteries secondaires et, plus particulièrement, un système de charge de batteries secondaires qui permet à une tension de début de charge d'une batterie secondaire d'être proche d'une tension rechargeable de la batterie secondaire en tenant compte d'une chute de tension, et détecte une tension de charge de la batterie secondaire en temps réel pour ainsi réguler la tension de charge, afin de réduire alors, de 40 minutes à 10 minutes, un temps de charge nécessaire pour charger la batterie secondaire de 20 % à 80 %.
