Abstract

The invention discloses a charging control device and method for a mobile terminal. The charging control device includes a detection module, a judgment module, a charge control module and a power supply management module. The detection module sets the power percentage and the battery voltage obtained when a charger is inserted as reference power percentage and reference voltage, and detects the power percentage at the beginning of charging and the battery voltage during the operation of the charger. The judgment module inactivates the charge control module when judging that the power percentage is greater than or equal to the reference power percentage, and controls the power supply management module to boost the battery voltage when judging the battery voltage is less than the reference voltage. The charge control module calculates a difference between the boosted battery voltage and the preset reference comparison voltage, determines the difference between the difference value and the increment of the charging voltage, and outputs the boosted battery voltage or the reference voltage to the power management module for charging according to a judgment result. The charging control device and method boost the charging voltage to a value meeting normal charging requirements and enable a lithium battery to output correct amount of electricity.

Description

technical field [0001] The present invention relates to the technical field of charging, in particular to a charging control device and method for a mobile terminal. Background technique [0002] When the smart mobile terminal is charging, within a short time after plugging into the charger, the power percentage of the smart mobile terminal will increase rapidly due to the opening of the corresponding charging module, and the battery voltage of the lithium battery will be pulled down instantly when abnormal charging occurs. This will interfere with the correct output of lithium battery power. If the corresponding voltage is inaccurate, the power output will be inaccurate. Display the wrong current battery level to the user, thereby misleading the user. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] In view of the deficiencies of the prior art above, the purpose of the present invention is to provide a chargi...
