发明名称 Battery charger and charging method
摘要 The charging method includes the steps of charging a battery pack, sensing voltage of the battery pack, calculating voltage change rate, detecting a first inflection point based on the voltage change rate so long as a voltage step is not detected, detecting a second inflection point based on the voltage change rate so long as a voltage step is not detected, and reducing current sent to the battery pack when both first and second inflection points have been detected.
