Abstract
A fast charging method for a parallel battery pack is provided, including: obtaining a maximum charging current allowed by a charging trunk and a charging current required for charging a parallel battery pack; comparing the charging current required for charging the parallel battery pack with the maximum charging current allowed by the charging trunk; if the charging current required for charging the parallel battery pack is less than or equal to the maximum charging current allowed by the charging trunk, performing parallel charging on battery units; or if the charging current required for charging the parallel battery pack is greater than the maximum charging current allowed by the charging trunk, changing some or all of battery units in the parallel battery pack to a series connection, and performing series charging on the battery units. The fast charging method for a parallel battery pack can effectively shorten a charging time.
