METHOD AND DEVICE FOR CHARGING A LITHIUM-ION BATTERY BY PULSES

摘要

The method comprises a step of charging (E1) during which a succession of pulses of charging current is applied. The charging comprises at least two successive charging phases (P1, P2): the first phase is characterized by amplitudes of charging current which are on average greater than a predefined limit current and the second phase is characterized by amplitudes of charging current which are on average less than the predefined limit current. The predefined limit current is a standard charging current specified by the constructor of the battery. The successive pulses have decreasing amplitudes and the charging comprises at least two successive charging phases (P2), the second phase (P2) having a higher rate of decay than that of the first phase.
