Abstract
A fast charging method, a fast charging system, and a fast charging apparatus for a series battery pack, where the fast charging method including obtaining charge parameters of battery units in a series battery pack, determining, based on the charge parameters, whether there is a differentiated battery unit in the series battery pack, where the differentiated battery unit is a battery unit whose charge parameter is different from a charge parameter of the rest battery units in the series battery pack, and changing the battery units in the series battery pack to a parallel connection when there is a differentiated battery unit in the series battery pack, and performing parallel charging on the battery units. Hence, the fast charging method for a series battery pack can effectively shorten a charging time.
