The disclosure discloses a mobile terminal and a rapid charging method, where the mobile terminal includes a microprocessor configured to detect voltage of a battery core thereof upon detecting that the USB interface is connected with the DC-charging power source adaptor, if the voltage of the battery core is in a range [S1, S2] delimited by preset DC-charging thresholds, to calculate a target charging voltage value Vfrom the voltage of the battery core, the maximum terminal voltage supported by the battery as well as at least one of a resistance value on a charging line, a resistance value on a circuit board of the mobile terminal, an inner resistance of the battery, and to send the target charging voltage value Vto the DC-charging power source adaptor to control the DC-charging power source adaptor to output charging voltage to DC-charge the battery.

Mobile terminal and rapid charging method

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.
