Abstract
The charging method repeatedly charges and suspends charging to pulse charge a rechargeable battery. Charging is suspended only after a given amount of charge is transferred to the battery. Battery voltage is measured during the period of suspended charging, and charging is resumed only after the voltage of the battery drops below a first prescribed voltage. This situation is continuously repeated to pulse charge a rechargeable battery.
