BATTERY-CONTROLLED CHARGING OF A RECHARGEABLE BATTERY

摘要

Methods and apparatus for recharging a rechargeable battery (202) having step charge requirements, where the charge current is tapered as successive voltage thresholds of the step charge requirements are approached. The battery (202) is programmed with a charge tapering algorithm, so that the battery charger (208) need not be programmed with battery-specific information. The charge tapering algorithm is used in conjunction with the step charge requirements and a measurement of one or more properties of the battery to determine an appropriate charge current as a function of time.
