Description

technical field [0001] The present invention relates to the field of charging, in particular to a charging method and device, a system, a charging circuit, a terminal, and a charging system. Background technique [0002] Terminals such as mobile phones have become life tools in various aspects such as communication interaction and digital entertainment, and large-capacity batteries have become a typical configuration of terminals. The large capacity of the battery and the pattern of frequent use make fast charging an important aspect of the end-user experience. As the charging rate of the battery increases, the charging current of the battery increases. How to make the battery obtain a larger charging current when charging the terminal, shorten the charging time, and improve the user experience of the terminal has become an important direction in the terminal research and development process. Especially when the USB organization releases USB PD 3.1, the VBUS of USB can supp...
