Problems solved by technology

[0003] However, the above method has disadvantages: if the threshold voltage is set too high, the charging current will be too small, causing the charger not to exert its maximum charging capacity, and the charging efficiency will be low; if the threshold voltage is set too low, the charging current will be too large, Cause the charger to be in an overload state, reducing the reliability and service life of the charger

Abstract

The invention discloses a method and system for regulating charging current and an electronic terminal. The method comprises the steps of obtaining current charging current and current input voltage of a charging module by the terminal when the charging module is charged by using a charger, wherein the charging current is gradually increased at a set step length; calculating relevant values of a current load regulating rate by using the current charging current and the current input voltage; judging whether the charger is in overload or not by using the relevant values of the current load regulating rate; if the charger is in overload, subtracting the set step length from the current charging current and then setting the result to be a maximum charging current value permitted by the charging module; and if the charger is not in overload, increasing the current charging current at the set step length and repeatedly executing the steps. According to the method and the system, the actual charging capacity of the charger can be detected, so that the charger can charge the terminal with safer and more effective current.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a charging current adjustment method and system, and an electronic terminal. Background technique [0002] At present, the load capacity of the charger is uneven, so when the terminal uses different types of chargers to charge, it needs to detect the actual charging capacity of the charger, so as to use the maximum output current of the charger for charging. The following method is usually used for detection: gradually increase the charging current, and then detect the output voltage of the charger. When the output voltage of the charger is lower than the threshold voltage, the charging current corresponding to the output voltage is considered to be the maximum output current. The terminal implements charging with this charging current. [0003] However, the above method has disadvantages: if the threshold voltage is set too high, the charging current will be too small, causing...
