Abstract
A charging method and a battery pack are provided. The charging method for charging multiple cells of the battery pack include steps of: charging the cells of the battery pack using a charging voltage, and detecting a voltage difference ΔVTDV between the cells, wherein a value of the charging voltage is a rated charging voltage value; and obtaining a new charging voltage value smaller than the rated charging voltage value according to the voltage difference ΔVTDV between the cells, and decreasing the charging voltage to the new charging voltage value for charging the cells.
