CHARGE EQUALIZATION SYSTEM FOR BATTERIES

摘要

The invention relates to an equalization system for batteries, comprising at least two accumulator stages (Eti) in series, each accumulator stage (Eti) comprising at least one accumulator (Aij). According to the invention, said system comprises: at least one voltage generator (7) having at least one positive pole (v2) and at least one negative pole (v1); an associated charging device (5) for each accumulator stage (Eti), powered by said at least one voltage generator (7) and comprising at least one inductance, at least one capacitor having a first end connected to said positive pole of said at least one voltage generator (7), at least one diode connected to the negative pole of said accumulator stage by its anode and to the first end of said at least one inductance by its cathode, and at least one switch that is connected to an end of said at least one inductance by one end; and a control device (3) for controlling said at least one voltage generator (7), for closing said at least one switch of a charging device (5) associated with an accumulator stage to be charged, so that said at least one inductance stores energy, and for transferring said energy to said associated accumulator stage.
