Before describing embodiments of the present invention in further detail, the terms and terminology involved in the embodiments of the present invention will be described, and the terms and terminology involved in the embodiments of the present invention will be used in the following explanation.
(1) In response to a condition or state that is used to represent the condition or state upon which the performed operation depends, the performed operation or operations may be in real-time or with a set delay when the condition or state upon which it depends is satisfied; without being specifically described, there is no limitation in the execution sequence of the plurality of operations performed.

With respect to the development of digital products, the number of electronic devices for various types has increased drastically over the past few years, and the push-out speed of new devices has not shown signs of slowing down. Devices such as tablet computers, laptop computers, desktop computers, single body computers, cellular telephones, storage devices, wearable computing devices, portable media players, navigation systems, monitors, and other display devices, power adapters, etc. have become ubiquitous.
Many of these devices are portable devices with internal batteries that allow users to freely carry and use wherever they walk. The internal battery in these portable devices may be charged through a cable connected to a power adapter that may convert AC power at the wall outlet to DC power that may be used by the portable device to charge its internal battery.
Users often need to carry these power adapters with them, especially when traveling or going out for a significant amount of time. For this and other reasons, it may be desirable for these power adapters to have a small form factor. Some of these portable electronic devices may have large internal batteries and users may wish to quickly charge these batteries. For example, they may have only a limited time to acquire a wall outlet before they need to leave. Thus, it may be desirable for these power adapters to be able to provide a large amount of power despite the limited size.
The user also typically has more than one device that needs to be charged. For example, they may wish to work on a laptop while charging the phone. Thus, it may be desirable for a power adapter to be able to charge more than one device at a time. But the corresponding charging protocols for different electronic devices are different, and various high-power quick-charging adapters are proposed for different electronic brands. Because of the different protocols and brands of power adapters, security certification for multiport adapters is increasingly important. There is currently no technology in the prior art that enables the deployment of multi-device power with reduced power consumption.
With reference to fig. 1, an embodiment of the present application provides an intelligent multi-port adapter charging control system, which includes an adapter and a charging control device connected with the adapter. In an embodiment of the present application, the adapter includes a first port and a second port. The first port and the second port of the adapter correspond to the first electronic device and the second electronic device respectively. Specifically, in the embodiment of the present application, the adapter is a power adapter, that is, the power adapter is used to perform a charging operation on the second electronic device and the second electronic device.

This is particularly useful when two electronic devices are connected to a power adapter, which is then plugged into a wall outlet or other power source.
When it may not be possible to allocate power independent of the connection order, the power adapter may prioritize the power through the connection order with the power adapter. This may be useful in the case where two electronic devices without an internal battery are connected to a power adapter. Since these two electronic devices do not have an internal battery, they may need to be continuously powered by the power adapter for proper operation. The power adapter may allocate half of the maximum power to each of these electronic devices. However, if the combined two devices require more than maximum power, the power adapter may allocate the required power to the first connected electronic device and provide sufficient power to the second electronic device to operate in a low power state. In the case where it is unclear which electronic device is connected first, priority may be given to the electronic device connected to a specific one of the connector jacks.

Q (Q) 1 Dead time T using peak current control delay1 Calculated from ω in the following formula:
，/>wherein，/>In the embodiment of the application, 250ns is taken.
Wherein the dead time T delay2 The approximation is calculated as:

The charging control device in the embodiment of the application includes two modules, respectively:
and the voltage detection module is used for detecting states of the first electronic equipment and the second electronic equipment under the first voltage and the second voltage.
And the power adjusting module is used for outputting specific stable voltage to the first port and the second port, acquiring the power storage amounts of the first electronic equipment and the second electronic equipment in real time, and switching the power amounts corresponding to the first electronic equipment and the second electronic equipment according to the comparison relation of the power storage amounts.
Referring to fig. 2, a method for voltage regulation of a charging control device may be provided for an intelligent multiport adapter charging control method, where the method includes:
and S210, detecting the connection state of the first electronic device and the second electronic device.
In this embodiment of the present application, the connection state of the corresponding electronic device needs to be determined before charging, where the determination of the connection state is implemented based on the detection switch module, specifically, the connection state of the first port and the second port, that is, the connection state of the first electronic device and the second electronic device, is determined by the charging control device that wants to detect the detection command issued by the switch module.
In other embodiments, for the connection state, the detection switch module may further upload a command to the charging control device for the circuit state change, and the charging control device determines the states of the first port and the second port, that is, the connection states of the first electronic device and the second electronic device, based on the information obtained by uploading.
And S220, determining that the first electronic equipment and the second electronic equipment are charged at the first voltage and the second voltage.
For the embodiment of the application, the first voltage is the current power storage amount of the first electronic device, and the second voltage is the current power storage amount of the second electronic device, where the second voltage is higher than the second voltage.
Determining the current power storage amounts of the first electronic equipment and the second electronic equipment, and charging according to the current power storage amounts of the first electronic equipment and the second electronic equipment, wherein the method specifically comprises the following steps:
and determining the current power storage amounts of the first electronic equipment and the second electronic equipment, and determining that the first electronic equipment and the second electronic equipment are charged under a first voltage and a second voltage when the current power storage amounts of the first electronic equipment and the second electronic equipment are lower than a threshold value.
In this embodiment of the present application, the threshold includes a first preset threshold and a second preset threshold, where the first threshold is a general threshold, and the determination of the second threshold is based on a target field in description information about the first electronic device and the second electronic device in a protocol of the first electronic device and the second electronic device, where the target field is used to characterize model information of the first electronic device and the second electronic device.
Specifically, the determination for the threshold includes the following processing procedures: acquiring a target field in the description information about the first electronic equipment in the first electronic equipment protocol, determining model information of the first electronic equipment and the second electronic equipment through the target field, and determining second preset thresholds of the first electronic equipment and the second electronic equipment through the model information; comparing the magnitude of the second preset threshold with the magnitude of the first preset threshold, and selecting the first preset threshold or the second preset threshold as a target threshold based on the magnitude relation between the first preset threshold and the second preset threshold.
Wherein selecting the first preset threshold or the second preset threshold as a target threshold for a magnitude relation based on the first preset threshold and the second preset threshold comprises: when the second preset threshold value is smaller than the first preset threshold value, determining that the second preset threshold value is a target threshold value; and when the first preset threshold value is smaller than the second preset threshold value, determining the first preset threshold value as a target threshold value.
In an embodiment of the present application, the first preset threshold for the first electronic device is that the first electronic device is charged to more than 70% capacity.
And S230, providing a first power amount and a second power amount for the first electronic device and the second electronic device.
In an embodiment of the present application, the first amount of power is greater than the second amount of power.
The first power and the second power are respectively power for charging the first electronic device and the second electronic device, wherein the first power is charging power for the first electronic device corresponding to the first voltage, and the second power is charging power for the second electronic device corresponding to the second voltage. Because the first voltage is greater than the second voltage, the amount of power is greater than the second amount of power for the first amount of power.
Wherein the power adapter may follow various algorithms to determine how to distribute power among the plurality of devices connected to the connector. For example, when only the first electronic device is connected to the power adapter, the power adapter may check for compliance with the power delivery communication method.

The power adapter may also request information such as whether the first electronic device is in compliance with the latest version of the USB-PD, whether the first electronic device has a battery, and what amount of charging power is on the battery. The power adapter may also request information about how much current the first electronic device may request at different power supply levels. The first electronic device may then request its required power from the power adapter, up to a maximum power.

Because the battery capacities of the first electronic device and the second electronic device are different, the battery types are different, and the corresponding charging efficiencies are different. Therefore, for the real-time charging of the first electronic device and the second electronic device in the charging process, the real-time power storage amounts of the first sub-equipment and the second electronic device need to be determined at the same time, and the charging control logic in the current state is switched according to the real-time power storage amounts obtained in real time. When the power storage amount of the first electronic equipment is larger than that of the second electronic equipment, the first voltage and the second voltage are switched, and conversion of charging power amounts of the first voltage and the second voltage is achieved.
Through the processing procedure, the first electronic equipment and the second electronic equipment can be enabled to conduct targeted charging operation, different first electronic equipment and second electronic equipment can conduct corresponding charging control according to the corresponding equipment characteristics and charging characteristics, overall charging efficiency is improved, and the method is applicable to different electronic equipment.
