Title:
QUICK CHARGE METHOD
Document Type and Number:
WIPO Patent Application WO/2010/034179
Kind Code:
A1
Abstract:
A quick charge method is provided. When a battery is charged, the battery stops charging when the battery is charged to the charge limit voltage, and the charge limit voltage is set to be U=2U0-Us, and Us is the stabilized voltage of voltage fallback after charging to U0 in constant current, U0 is the normal charge cutoff voltage used by a small multiplying power constant current-constant voltage charging mode which is normally accepted by the industries, and the stabilized voltage Us is defined as follows, begin timing when the battery stops charging in constant current, when the drop of open-circuit voltage of a battery is less than a certain value in a certain time segment, this means that the voltage of the battery is stable, and the voltage corresponding to the first time point of this time segment is considered as the stabilized voltage Us of the battery.
