Battery charging method of mobile terminal and device mobile terminal

Abstract

The invention relates to the field of electronic consumption, and particularly relates to a battery discharging method of a mobile terminal, a device and a mobile terminal. The method comprises the following steps of: utilizing a constant current to charge a battery, obtaining the internal resistance of the current battery, and obtaining the current charging cut-off voltage of the internal resistance of the current battery; and judging whether the current battery voltage is greater than or equal to the current charging cut-off voltage, if not, returning to the step to obtain the internal resistance of the current battery, and if so, utilizing the constant voltage to charge the battery. According to the mobile terminal and the battery charging method and the device provided by the invention, the mobile terminal charging cut-off voltage of the mobile terminal is adjusted through compensating the voltage consumed by the internal resistance of the battery, so as to prolong the charging time in the constant current step, thereby reaching the aim of rapidly charging with no increase of the cost, the charging speed is improved, the effect of the high current charging battery is more obvious, and the user experience is preferably promoted.

Description

technical field [0001] The invention relates to the field of electronic consumption, in particular to a method for charging a battery of a mobile terminal and a mobile terminal device. Background technique [0002] The battery internal resistance of the mobile terminal includes the internal resistance of the battery line, the ohmic internal resistance of the battery cell, and the polarization internal resistance of the battery cell. In the process of charging consumer electronic products such as mobile terminals, the battery charging of mobile terminals generally does not consider the voltage division of the internal resistance of the battery, which causes the cell voltage of the battery of the mobile terminal to not reach the charging cut-off of the battery during the constant current charging stage. The voltage battery is converted to constant voltage charging. After the conversion to constant voltage charging, the constant voltage charging current will gradually decrease,...
