This disclosure describes exemplary charging systems and methods for fast charging energy storage devices (e.g., battery cells of battery packs). An exemplary charging system may be configured to control charging of a charging circuit by employing repetitive intermittent discharge pulses. The control system may be configured to command the charging circuit to apply a discharge pulse current to the battery cell for a first time period, apply a charging current to the battery cell for a second time period that is significantly longer than the first time period, and then repetitively alternate between applying the discharge pulse current and the charging current until the battery cell reaches a predefined maximum voltage.
