Abstract
A system and method for charging rechargeable batteries is disclosed. A charging circuit monitors aspects of a rechargeable battery during charging and applies power to the terminals of the battery received from a power supply. The charging circuitry signals to a power supply to control the current or voltage applied to the charging circuitry based upon the monitored aspects of the battery and the type of charge storing compound within the cells of the battery. The charging circuitry and battery may be part of a rechargeable battery cartridge disposed within a compartment of a portable electronic device having a dynamic operational load. By controlling the power supply, the charging circuitry can simultaneously apply power to the operational load to operate the device while charging the battery.
