Abstract
Battery charger apparatus and method includes a clock to provide timing information and logic to control the charging time of a battery being charged. The logic also controls a discharge time period in which the battery being charged is discharged for a relatively short period of time. After the discharge time, the voltage across the battery terminals is sensed by the logic to determine the state of the charge of the battery. The pulsing of the battery, in which the charging times and discharging times are alternated, and then the sensing of the battery voltage, is controlled by the logic to provide the charging of a battery in the shortest possible time period.
