US 2019/0245362 A1 · Charging Protection Method, Terminal, and Charger

Abstract

This application provides a charging protection method, a terminal, and a charger. The terminal obtains a parameter from the charger, including at least one of an input voltage value and an output current value of the charger and a temperature value of a charging output port of the charger. When a parameter value is greater than a threshold, the terminal terminates a charging process based on a relationship between a corresponding threshold and at least one of a difference between the output current value of the charger and an input current value of the terminal, a power loss from the charger to the terminal, and a temperature value (including the temperature value of the charging output port of the charger and a temperature value of a charging input port of the terminal). A charging port can be prevented from being overheated, and a probability that an overheated charging port causes an accident can be effectively decreased.
