Mobile phone charger and safety authentication method and system thereof

Abstract

The invention discloses a mobile phone charger and a safety authentication method and system thereof. When a mobile phone is connected with the charger for charging, wireless communication between the mobile phone and the charger is started, charging parameters of the mobile phone are obtained, and the mobile phone carries out step-by-step adjustment on charging currents according to charging parameters of the charger from small to large. The step-by-step adjustment is carried out in such a way that charging safety matching is performed from preset safe charging currents, an adjustment current scope is calculated according to the charging parameters of the charger, then maximum charging currents are determined according to a charging safety matching result, and finally, the mobile phone is charged according to the maximum charging currents. According to the invention, through safety matching on the charger, charging safety hidden trouble caused by an unauthenticated charger in a charging process can be eliminated, the demand for charging efficiency can be met, and the safety requirement for charging can be better guaranteed.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a safety authentication method for a mobile phone charger and a system for applying the method. Background technique [0002] The penetration rate of smart phones has become higher and higher. Mobile phones have become the electronic products that we touch the most in our daily lives, and they are also a kind of electrical appliances. Although mobile phones are much less dangerous than ordinary household appliances, recently mobile phone charging has caused people Reports of electrocution still make everyone pay attention to the safety hazards of mobile phones. [0003] From the perspective of charging safety, only chargers certified by mobile phone manufacturers can more effectively ensure the safety of the charging process, especially in order to meet the increasingly urgent needs of fast charging for mobile phone users today. The safety of charging is also the same. are also...
