Abstract

A previous patent (#5,184,059) teaches the use of a fixed element (capacitor, Cc) to further expand the battery capacity identification scheme. (Refer to figure below) This is accomplished by measuring not just the resistor divider voltage reached by the pull up resistor in the charger and the battery iden- tification resistor (Rc) in the battery, but also the time constant that is created by the battery identifi- cation resistor (Rc) and the fixed element (Cc).
