ABSTRACT:
Battery type is determined by measuring effective resistance of a thermistor/resistor network (205, 206, and 207) and one or more of a plurality of current sources (303-305) is enabled to provide the appropriate charging current. Measurement of necessary charging parameters and provision of appropriate charging current are accomplished through an interface to the battery pack undergoing charge that comprises only three connections (313-315).
