Abstract
A method of charging a battery, including: in an mcharge and discharge cycle, constant-current charging a battery to a first cut-off voltage Uat a charging current, where m is any two or more integers of 1, 2, 3, . . . , x, and Uhas different values in at least two charge and discharge cycles. The method shortens fully charged time of a battery and further ensure that phenomena of lithium precipitation and overcharge do not occur on the battery, thereby prolonging a service life of the battery.
