Title:
METHOD AND DEVICE FOR PERFORMING LARGE-CURRENT CHARGING ON INTELLIGENT TERMINAL
Document Type and Number:
WIPO Patent Application WO/2014/173045
Kind Code:
A1
Abstract:
A method and device for performing large-current charging on an intelligent terminal. The method comprises: when signal lines of a positive and negative data line terminal are in a short-circuit state, switching the power supply to a large-current power supply, increasing a charging current gradually, and synchronously detecting a corresponding charging voltage; according to the charging voltage, judging whether the charging current is an overcurrent or not; and when the charging current is an overcurrent, reducing the charging current, thereby enabling the intelligent terminal to be charged at a large current, and shortening the charging time.
