Abstract

The invention discloses a detection method and a detection system for a charging voltage. The detection method for the charging voltage comprises the steps that a current detection module detects a charging current when a mobile terminal is charged; then a peak detection module detects an average peak of multiple peaks of the current charging current during a preset period; and then a voltage conversion module converts the average peak of the charging current into a corresponding charging voltage value. Through detection of the average peak of the charging current and conversion of the peak into the corresponding charging voltage value, the value of the charging voltage output by a charger can be detected accurately; accuracy of charging voltage detection is increased; demands of intelligent mobile terminals for different charging currents and charging periods can be satisfied; and users' experience can be improved.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a method and system for detecting charging voltage. Background technique [0002] With the development of smart mobile terminals, the battery capacity is getting bigger and bigger, the charging current is getting bigger and bigger, and the charging time is getting shorter and shorter. Then the output voltage of the charger needs to support different charging currents, so as to meet the requirements of charging current and charging time of the smart mobile terminal. [0003] This requires detection of different output voltages of the charger to prevent the output voltage of the charger from being able to support the charging current of the lithium battery of the smart mobile terminal. Terminal charging current and charging time requirements. [0004] Thereby prior art still needs to improve and improve. Contents of the invention [0005] In view of the shortcomings o...
