Title: ELECTRIC CHARGING PROTECTION METHOD, TERMINAL, AND CHARGER
Abstract:
Provided are an electric charging protection method, a terminal, and a charger. The method comprises: a terminal acquiring, from a charger, parameters comprising at least one of an input voltage value, an output current value or a temperature value at a charging output port of the charger; and the terminal comparing at least one of a difference between the output current value of the charger and an input current value of the terminal, a loss of power from the charger to the terminal or temperature values (comprising the temperature value at the charging output port of the charger and a temperature value at a charging input port of the terminal) with a threshold corresponding thereto, and if the parameter is greater than the threshold, terminating a charging process to prevent overheating of a charging port. The invention can effectively reduce a probability of occurrence of an accident resulting from overheating of a charging port.
