METHOD FOR MANAGING CHARGING OF A RECHARGEABLE BATTERY

摘要

The management method comprises a charging stage (F2, F3) and optionally a prior stage (F1) for evaluating the charge state of the battery. The comparison, with a full-charge threshold, of the absolute value of the slope (P) of the voltage at the terminals of the battery, at the end of each period, while applying a drawn current, is used as an end-of-charging criterion in the charging stage and/or as a full-charge criterion in the stage for evaluating the charge state. The charging stage using drawn current (F3) is interrupted when the slope (P) reaches the full-charge threshold. This same comparison forms the criterion for judging the necessity of carrying out a charging step (F2, F3) after the prior stage (F1) for evaluating the charge state of the battery.
