Abstract
A battery charging system determines a current condition of a battery in real time and dynamically determine a threshold voltage for controlling a charging mode of the battery based on the current battery condition. The battery charging system charges the battery using a constant current (CC) mode or constant voltage (CV) mode based on the battery voltage and the dynamically determined threshold voltage. The battery charging system can determine the voltage and current of the battery in real time without receiving information on the battery from the power receiving side of the battery charging system.
