Abstract
The invention relates to a method and a system for managing the charging of a rechargeable battery by a voltage control or by a current control comprising a plurality (n) of branches connected in series, each branch comprising a plurality (p) of electrochemical elements connected in parallel. Each electrochemical element exhibits a charging profile (PC) comprising at least one plateau zone directly followed by a sloping zone in which the variation of the voltage as a function of the state of charge in the plateau zone is on average at least ten times less fast than the variation of the voltage in the sloping zone.
