Embodiment Construction

[0117] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0118] At present, most chargers capable of fast charging that follow the USB PD protocol do not have an authentication function. Some chargers with authentication function use private protocols for communication. It is necessary to set up a dedicated controller on the charger, and it is necessary to configure corresponding hardware and software on the electric device to be able to connect the e...

Abstract

The invention relates to a charging control method and device, electric equipment, charging equipment, a system and a medium. The method applied to the electric equipment following a USB PD protocol comprises steps that the second authentication information of the charging equipment is received; judging whether a first preset data segment of the generated first authentication information corresponds to a first preset data segment of the second authentication information or not; if the first preset data segment of the first authentication information corresponds to the first preset data segmentof the second authentication information, sending the first authentication information to the charging equipment; and determining a charging state according to the received second authentication result of the charging equipment. According to the charging control method disclosed by the invention, in the charging process, the electric equipment firstly performs first authentication on the chargingequipment, and the charging equipment performs secondary authentication on the electric equipment, and determines the charging state according to the two authentication results, so the compatibilityof the electric equipment to the charging equipment is improved, the situation of unreasonable use of the charging equipment is avoided, and use experience of a user is improved.

Description

technical field [0001] The present disclosure relates to the technical field of charging, and in particular to a charging control method, device, electrical equipment, charging equipment, system and medium. Background technique [0002] With the acceleration of people's life rhythm, higher requirements are put forward for the charging speed of mobile phones, notebook computers and other electrical equipment, which requires higher charging power per unit time. [0003] Therefore, more and more mobile phone manufacturers have begun to equip their mobile phones with chargers that comply with the USB PD protocol to charge their mobile phones, so as to achieve the effect of fast charging and improve the use needs of users. In order to standardize the high-power charging process of electric equipment and charging equipment, relevant organizations require that the USB PD protocol be followed for communication during the charging process using high-power chargers. [0004] At prese...
