Abstract
A lithium battery pack according to the present invention has inherent information stored therein, which may include a nominal voltage, maximal voltage of the cells, range of temperature etc. A charging control signal is determined by a charging controller based on an identified state of the cells and the inherent information, and is transmitted to an electrical charging device. A controlled module in the charging device receives the charging control signal through and adjusts an output current to an accurate charging voltage for the current state of the battery pack.
