Abstract:
Battery cell charge equalization devices, systems and methods are provided. A particular method includes receiving a charging current at a battery charge equalization circuit coupled to a battery cell of a multi-cell battery. The method also includes routing at least a portion of the charging current away from the battery cell when a voltage of the battery cell satisfies a first voltage threshold. The method further includes establishing a second voltage threshold in response to the voltage of the battery cell satisfying the first voltage threshold. The second voltage threshold is lower than the first voltage threshold. The charging current is routed away from the battery cell while the voltage of the battery cell satisfies the second voltage threshold.
