Abstract
Discharging a battery is accomplished by: applying an electrical stimulus to the battery; measuring a response to the electrical stimulus, the measured response providing an indication of discharge efficiency of the battery; determining a target frequency corresponding to a maximum discharge efficiency; and then discharging the battery with a discharge current profile comprising current pulses having a frequency component selected based on the determined target frequency.
