Problems solved by technology

[0003] Among them, due to the DC loss and switching loss in the charging process, the charging efficiency cannot reach 100%.
However, in the prior art, the mobile terminal charges the mobile terminal by controlling the charger to output a fixed voltage, which does not quantitatively judge the impact of the above two losses on the charging efficiency under the output voltage, so there is no Find the optimal output voltage to minimize the two losses, thereby maximizing the charging efficiency

Abstract

The invention discloses a charging method and a charging system. The charging method comprises the steps of enabling a processor to control a charger to reduce an output voltage based on a preset rule, and charging a mobile terminal by the reduced output voltage; obtaining an output voltage and an output current output by the charger, and a charging voltage and a charging current output by a charging chip when the mobile terminal is charged by different output voltages separately; obtaining charging efficiency values under different output voltages according to the output voltage, the output current, the charging voltage and the charging current; and enabling the processor to control the charger to charge the mobile terminal by the output voltage corresponding to the maximum charging efficiency value. By adoption of the mode, the output voltage of the charger can be dynamically regulated, so that the direct current loss and the switching loss can be reduced to the minimum when the mobile terminal is charged by the charger, and the maximum of the charging efficiency is further achieved.

Description

technical field [0001] The invention relates to the charging field, in particular to a charging method and a charging system. Background technique [0002] With the popularization of mobile terminals such as smart phones and the improvement of users' demand for the battery life of mobile terminals, the battery fast charging technology in mobile terminals can be quickly universal. The output voltage of the charger in the current battery fast charging technology is a controlled variable voltage value. At the beginning of charging, after the mobile terminal and the charger communicate and match, the mobile terminal controls the charger to output a fixed voltage, and then starts Charge. [0003] Wherein, due to the DC loss and switching loss in the charging process, the charging efficiency cannot reach 100%. However, in the prior art, the mobile terminal charges the mobile terminal by controlling the charger to output a fixed voltage, which does not quantitatively judge the i...
