Abstract

The invention discloses a multi-port fast charging mobile power supply circuit, which includes an input detection module, an output detection module, a path control module and a charging and discharging module. The module is connected to at least two USB input ports, and is used to detect the power bus VBUS signal and protocol signal of the USB input port, and the output detection module is connected to at least two USB output ports, and is used to detect the power bus VBUS signal and protocol of the USB output port Signals and external output control signals, each USB input port and USB output port are respectively connected to the charge and discharge module through a switch element, and the control end of the switch element is connected to the access control module. The present invention solves the problem that the multi-port fast-charging mobile power supply not only affects the fast-charging experience, but also has potential safety hazards by controlling the switching sequence of the paths.

Description

technical field [0001] The invention relates to the technical field of charging equipment, in particular to a multi-port fast charging mobile power supply circuit and a control method thereof. Background technique [0002] With the popularity of portable mobile devices such as mobile phones and tablet computers, there are more and more mobile phone peripheral accessories such as mobile power supplies, car chargers, adapters, etc., especially mobile power supplies that support fast charging functions, which can replenish mobile devices at any time. Electricity, while greatly shortening the charging time. At present, the interfaces of mobile devices, chargers, and USB cables are becoming more and more diverse, such as Type-A ports, Type-C ports, Micro-B ports, and Lightning ports. In addition, the battery capacity of mobile devices is getting larger and larger, and the battery capacity of mobile power sources is also increasing. In order to speed up charging and reduce chargi...
