ABSTRACT:
An integrated AC adapter and battery charger is disclosed. The apparatus comprises an AC adapter unit for converting AC power to a DC power and a battery charging apparatus coupled to the AC adapter unit for charging a battery pack. The battery charging apparatus further comprises a microcontroller for sensing the condition of the battery pack or tacks being charged, a memory for storing the proper charging profile for a number of different types of battery packs, and a charging current generator capable of generating a varying charging current based on the microcontroller's determination of the battery's condition and the charging profile stored in the memory.
