Apparatus and method for charging a battery, wherein a charging voltage is applied to a battery. The charging voltage depends on a base charging voltage which is continually adjusted in the direction that provides a more optimal level of charge acceptance. The direction of a more optimal charge acce ...

James K Klang: Apparatus and method for step-charging batteries to optimize charge acceptance. GNB Battery Technologies, Leydig Voit & Mayer, December 10, 1996: US05583416 (136 worldwide citation)

Apparatus and method for charging a battery, wherein a target voltage is applied to a battery. During charging, the applied voltage is periodically increased and decreased a predetermined amount to modify the applied voltage by a small step in either direction. The charging input is measured as the ...
