Abstract

The invention discloses a charging protocol communication method, which comprises the following steps that: power supply output equipment receives a charging data request, adjusts power supply outputparameters and determines charging data, and the charging data request consists of a first logic value, a second logic value and a guide pulse. The invention further discloses a charging protocol communication device and equipment and a readable storage medium. A charging data request sent by charged equipment is received through power supply output equipment; according to the charging data request, electrical parameters output by the power supply are adjusted, the electrical parameters are output, charging data are determined, the charging data request comprises an output voltage value, an output current limiting value and a cable resistance compensation value, and finally, the charging data request is sent through D + and D-signals of the charging interface. Charging protocol communication between the power output device and the charged device is realized.

Description

technical field [0001] The present invention relates to the communication field, in particular to a charging protocol communication method, device, equipment and computer-readable storage medium. Background technique [0002] The existing fast charging implementation methods include step-down and boosting. Many chip manufacturers and equipment manufacturers have their own fast charging protocol solutions. However, in the existing fast charging protocol solutions, the charging device interface voltage step Into large, there are few gears that support voltage regulation (that is, there are fewer selectable charging voltages), and the PPS sub-protocol of PD3.0 can support more voltage regulation gears, but it needs to use the CC signal in the type C interface for communication. It cannot support the USB cable from ordinary A port to micro USB port and the data cable from ordinary A port to type C port. Therefore, supporting standard USB cables and more voltage adjustment gears ...
