Abstract

The invention relates to the technical field of charging, particularly to a charging parameter verification method and equipment, and a charger, and aims to solve the problem of charging failure caused by the fact that safety threshold of each charging parameter cannot be effectively controlled and judged. The charging parameter verification method comprises the following steps: after a communication channel between a terminal and the charger is established successfully, the terminal reads charging capability information of the charger according to a preset way, compares a maximum capability value of the charger specific to each preset charging parameter and a target value corresponding to a corresponding preset charging parameter stored by the terminal, determines the minimum value as a first configuration value of the corresponding preset charging parameter, writes the first configuration value, obtained by comparison, of each preset charging parameter into the charger, and reads a second configuration value, specific to each preset charging parameter, of the charger; and after it is determined that all preset charging parameters are configured successfully, the terminal transmits charging confirmation indication to the charger.

Description

technical field [0001] The invention relates to the technical field of charging, and in particular, to a method and device for verifying charging parameters and a charger. Background technique [0002] With the rapid development of electronic products, the intelligent terminal system is becoming more and more intelligent, the functions of the intelligent terminal are becoming more and more powerful, and the accessories (such as chargers) of the intelligent terminal are gradually becoming more intelligent. [0003] In fact, the requirements of higher current, shorter charging time and safer charging protection put forward higher requirements for the future application of chargers. Therefore, chargers gradually tend to be digitally controlled and form an intelligent charging control system with smart terminals. become the trend of future development. [0004] At present, the batteries of smart terminals mainly use lithium batteries, and the charging safety of lithium batterie...
