Abstract

The invention discloses a charging method and device. The method comprises the following steps: obtaining a currently demanded charging voltage and a currently demanded current of a terminal; and adjusting charging parameters of a charger according to the currently demanded charging voltage and currently demanded current of the terminal for charging the terminal. According to the charging method and device, the terminal load and the battery charging requirements are met by detecting the currently demanded current and the currently demanded charging voltage of the terminal in real time and dynamically adjusting the charging parameters (namely an output current and an output voltage) pre-output from the charger according to the currently demanded current and the currently demanded charging voltage, so that a battery is constantly kept at the optimal charging state point; and the charging effect and efficiency are ensured.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a charging method and device. Background technique [0002] When the traditional terminal is charging, the output current or voltage of the charger is constant. The charging chip limits the current at the load end of the terminal. The dynamic change of the terminal load will affect the current of the battery charging branch. When the output current of the charger remains constant, the system When the load becomes larger, the charging current of the battery will decrease. At this time, the battery may not be fully charged or cannot be charged, and eventually the charging time will be too long or it will not be fully charged. Contents of the invention [0003] The main purpose of the present invention is to provide a charging method and device, aiming to solve the technical problem of charging current or voltage changing due to load change in the existing charging method, ...
