Abstract
The present disclosure is directed to charging a battery pack by measuring an electrical impedance value of a battery pack by applying a sinusoidal AC excitation signal to a plurality of battery cells of the battery pack, measuring a total impedance value of the battery pack, obtaining a chemical impedance value of the battery pack based on the electrical impedance value and the total impedance value, and adjusting a charge current applied to the battery pack based on the chemical impedance value of the battery pack.
