Abstract : A battery charger analyzer utilizing a down pulse configuration employs a number of power switching transistors driven from a pulse-width modulator in a control section which monitors and analyzes the battery temperature, charge condition, current provided, and length of time in the charge cycle, all of which affect the operation of the pulsewidth modulator and thereby the charge supplied to the battery. The charger analyzer supplies 95% of the battery charge at either of two selected charging rates. (Author)
