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.
