The invention relates to the technical field of charging, and provides a charging method, a USB (universal serial bus) transmission line and power supply equipment. The charging method comprises steps as follows: the condition that the USB transmission line is connected to to-be-charged equipment is determined; model information of the USB transmission line is acquired; according to the model information of the USB transmission line, the USB transmission line executes charging operation on the to-be-charged equipment, so that the USB transmission line is flexibly used as an external USB transmission line; further, according to the model information of the USB transmission line, charging operation on the to-be-charged equipment can be executed, and the problems of USB transmission line heating and electronic equipment burning-out as well as other security problems due to mismatching of models are solved.
Description
technical field [0001] The invention relates to the technical field of charging, in particular to a charging method, a USB transmission line and power supply equipment. Background technique [0002] As the entertainment and playability of smart terminals are getting higher and higher, the problem of high power consumption of mobile phones is becoming more and more serious. Therefore, fast charging is used to solve the above problems, that is, high voltage or high current is usually used to realize charging of smart terminals. Whether it is a high-voltage method or a high-current method, the impedance of the entire charging path is required to be as small as possible, especially the impedance of the USB (Universal Serial Bus) transmission line used in the transmission process should be as small as possible. . At present, there are two connection structures between the charging adapter or mobile power supply and the USB transmission line: the first is that the charging adapte...
