Abstract
The present invention provides a quick charge method belonging to the field of the battery and particularly relates to a quick charge method for lithium ion battery and polymer lithium ion battery. During a battery is being charged, the battery stops charging when the battery is charged to a charge limit voltage, and the charge limit voltage between two poles of the battery is set to be U=2U−U, and Uis a stabilized voltage which the voltage of the battery falls back to after the voltage of the battery is charged to Uat a constant current, Uis a standard charge cutoff voltage used by a low rate constant current-constant voltage charging mode which is normally accepted by the industries, and the stabilized voltage Uis selected as follows: timing begins when the battery stops charging at the constant current, and from a certain time segment, when the drop of an open-circuit voltage of the battery is less than a certain value within the certain time segment, which means that the voltage of the battery is stable, and a voltage corresponding to the first time point of this time segment is selected as the stabilized voltage Uof the battery.
