Mobile Terminal, DC-Charging Power Source Adaptor, And Rapid Charging Method

摘要

This disclosure provides a mobile terminal, a DC-charging power source adaptor, and a rapid charging method, which are proposed for a power source adaptor outputting dynamically adjustable voltage, where core voltage of a battery is divided into several intervals, and further in a segmented constant-current-like charging mode, a volt value of charging voltage output by the power source adaptor is adjusted dynamically according to the interval in which the core voltage of the battery in the mobile terminal while the battery is being charged lies, and the battery is DC-charged directly using the charging voltage output by the power source adaptor.

主权项

1. A mobile terminal, comprising:
a battery configured to store electric energy; a USB interface configured to be connected with a DC-charging power source adaptor; and a microprocessor configured to detect voltage of the battery upon detecting that the USB interface is connected with the DC-charging power source adaptor; if the voltage of the battery is in a range [S1, S2] delimited by preset DC-charging thresholds, to send the voltage of the battery to the DC-charging power source adaptor, so that the DC-charging power source adaptor outputs target charging voltage corresponding to the current voltage of the battery, and to transmit the target charging voltage output by the DC-charging power source adaptor directly to the battery to DC-charging the battery.
