Systems and Methods of Battery Charging with Dynamic Float Voltage

摘要

Embodiments of the present invention include electronic circuits, systems, and methods for charging a battery. In one embodiment, the present invention includes a method, which may be implemented by an integrated circuit, comprising charging the battery using a constant current until the voltage on the battery increases to a first voltage level, and charging the battery using a constant voltage, wherein the constant voltage is set to a second voltage level. The constant current charging transitions to constant voltage charging when the voltage on the battery reaches the first voltage level, where the first voltage level is greater than the second voltage level.
