ABSTRACT:
A device for controlling the discharge of a battery supplying an intermittent load, such as a nerve stimulation device. The device includes a controller which operates a switched inductor to feed a capacitor with numerous small pulses from the battery, thereby building up the charge and voltage on the capacitor, and occasionally discharging the capacitor to a load. The capacitor discharge is at a higher current than the small pulses from the battery, so the battery is drained at small instantaneous discharge rates compared to the high instantaneous discharge current from the capacitor.
