Circulating fan

This application provides a method for determining a charger, a related device, and a system. The method includes: detecting, by an electronic device, a charging current output from a charger; when amplitude values of the charging current are a sequence of variable current, quantifying the current sequence into a binary sequence; determining whether the quantified binary sequence is the same as a prestored binary sequence; and when the quantified binary sequence is different from the prestored binary sequence, outputting prompt information indicating that the charger is a non-standard configuration charger. According to the present invention, whether the charger is a standard configuration charger is determined. This manner is simple and convenient. In addition, no specific device detection module needs to be disposed on the charger.

Method for determining charger, related device, and system

The present disclosure relates to a method for checking a charging parameter. The method includes: after a communication channel between a terminal and a charger is successfully established, reading, by the terminal, charging capability information of the charger in a preset manner; comparing a maximum capability value of the charger for each preset charging parameter with a target value that is corresponding to a corresponding preset charging parameter and that is stored in the terminal, and determining a minimum value as a first configuration value for the corresponding preset charging parameter; writing, into the charger, the first configuration value that is obtained by means of comparison and that is for each preset charging parameter; reading a second configuration value of the charger for each preset charging parameter; and sending, by the terminal, a charging acknowledgment instruction to the charger after determining that all preset charging parameters are successfully configured.
