ABSTRACT:
A battery charging system (300) is capable of maintaining a fully charged battery (304) without overcharging or undercharging the battery regardless of the chemistry type, number of cells, state of charge, or rated charge current. A charging technique (200) allows a charger (306) to sense a capacity indicator of the battery, through a capacity resistor (Rc) or memory (302) located in the battery (304), and translate data pertaining to the number of battery cells, the battery chemistry, and the rated charge current into a relative impedance (210), a cutoff adjustment voltage (212), and a stead state cutoff voltage (214). An adjusted steady state cutoff voltage is determined (216) and used as a threshold with which to compare the battery voltage (220).
