Abstract
The present disclosure is directed to charging a battery pack by determining a battery pack identification (ID) value from a battery pack identification (ID) component of the battery pack, applying a sinusoidal AC excitation signal to a set of battery cells of the battery pack, calculating an impedance value of the battery pack based on the sinusoidal AC excitation signal, comparing the impedance value of the battery pack to a set of reference impedance values associated with the battery pack ID value, and selecting a charging scheme based on a comparison of the impedance value of the battery pack to the set of reference impedance values associated with the battery pack ID value. The battery pack is charged using the charging scheme.
