Problems solved by technology
[0002] At present, there are more and more fast charging devices with multiple USB output ports on the market. Generally, there are two mainstream solutions: one is to add a DC converter for two independent power supply circuits or secondary; to meet the needs of fast charging and different charging Different voltages, this solution doubles the components, large volume and high cost
Another solution is to use only one main power supply and one fast charging circuit internally to save costs, but this requires the circuit to be switched, that is, when two devices are charging at the same time, only one of the devices can provide fast charging

The invention discloses a charging circuit control method, a charging circuit control device and a computer readable storage medium, which are used for controlling a charging circuit and realizing quick charging of double devices. The method is applied to the charging circuit, the charging circuit is provided with an input end, a first output end and a second output end which are mutually coupled, the input end is used for being connected with a power supply, and the first output end and the second output end are used for being connected with power receiving equipment. Judging the charging specification of the first power receiving equipment according to the charging feedback of the first power receiving equipment; if the charging specification of the first power receiving equipment is greater than 9V, controlling the first output end to provide charging corresponding to the charging specification of the first power receiving equipment for the first power receiving equipment; and when the second power receiving equipment is connected to the second output end, controlling the second output end to charge the second power receiving equipment according to the charging specification of the second power receiving equipment.
Description
technical field [0001] The present application relates to the technical field of circuit control, and in particular to a charging circuit control method, device and computer-readable storage medium. Background technique [0002] At present, there are more and more fast charging devices with multiple USB output ports on the market. Generally, there are two mainstream solutions: one is to add a DC converter for two independent power supply circuits or secondary; to meet the needs of fast charging and different charging Different voltages, this solution doubles the components, large volume and high cost. Another solution is to use only one main power supply and one fast charging circuit internally to save costs, but this requires the circuit to switch, that is, when two devices are charging at the same time, only one of them can provide fast charging. Therefore, there is an urgent need for a relatively complete dual-port fast charging solution. Contents of the invention [...
