Abstract
A method of charging an electrochemical generator having a plurality of electrochemical cells. The method includes the step of charging the plurality of electrochemical cells such that the total voltage of the generator reaches a predetermined voltage level, followed by the steps of selecting a particular electrochemical cell and charging the particular electrochemical cell to its respective maximum voltage, such that the cathode(s) of the particular electrochemical cell is(are) restored to a fully-charged state. Once it has been restored to its fully-charged state, the particular electrochemical cell is allowed to discharge itself down to a nominal voltage. Each of the plurality of electrochemical cells of the generator is selected and charged to its respective maximum voltage in turn, according to a predetermined selection sequence.
