Based on any one of the three situations, the electronic device considers that the power supply parameter of the first electrical device needs to be adjusted. Through the foregoing steps 202 and 203, the adjustment of the power supply parameter of the first electrical device by the electronic device will cause the power supply parameter output by the electronic device to the second electrical device to change, so as to adjust the power supply parameter of the first electrical device and the power supply parameter of the second electrical device.

In a third embodiment of the power supply method provided by the present application, as shown in fig. 3, the method includes:
step 301: under the condition that a signal representing that power supply energy output by power supply equipment for supplying power to electronic equipment changes is obtained, determining that a preset condition is met, and obtaining a trigger instruction;

It should be understood by those skilled in the art that the same contents related to the second embodiment and the third embodiment of the power supply method as those related to the first embodiment are referred to the description of the first embodiment, and detailed description is not repeated here.
The embodiments of the present application will be further described with reference to fig. 4 and 6.
The electronic equipment is used as a docking station and at least has four interfaces: for example, with reference to fig. 4 and 5, the first interface and the second interface are used as uplink interfaces to supply power to the connected first electrical device and the second electrical device. The first electric equipment can be a notebook computer, and the second electric equipment can be a mobile phone. The third interface is used for connecting a power supply device such as an adapter to obtain energy which can supply power to the first and second electrical devices. The fourth interface is used as a downlink interface for connecting any peripheral equipment such as a U disk, a wireless mouse, a keyboard and the like, and needs to consume a certain amount of electricity. The first interface, the second interface and the fourth interface are preferably Type-c interfaces. The fourth interface may also be a USB-a interface. The third interface may be any reasonable interface capable of connecting an adapter such as a USB-a or USB-c interface.
In the embodiment of the present application, the docking station further includes a controller (Control) and a Micro Control Unit (MCU). The controller is configured to communicate with a first electrical device and a second electrical device connected to a first interface and a second interface, specifically, communicate based on a power transfer (PD) protocol, and please refer to related descriptions for a specific communication process based on the PD protocol, which is not described in detail.
Assuming that the docking station does not supply power to any electric device, such as a notebook computer and a mobile phone, as shown in fig. 5 and fig. 6, the power supply device, such as an adapter, is connected to the docking station through the third interface, the power input by the adapter to the docking station is P0, the power required for the operation of the docking station itself is P1, if the downstream interface is connected to a peripheral, the power consumed by the peripheral is considered to be P2, otherwise, if P2 is 0, the docking station may set the total power supply to the devices connected to the first and second interfaces to be P4 to P0-P1-P2 (the power supply parameters provided by the docking station to the electric device).
The first electric device such as a notebook computer is connected into the docking station through the first interface-USB-c interface, the controller learns the power required by the first electric device-the notebook computer based on the PD protocol, and informs the MCU of the learned content. The MCU determines the power to be supplied to the notebook based on the power required by the notebook and the power P4 left in the docking station at that time. In this case, the value of P4 is usually larger than the power required by the notebook, the MCU allocates the power required by the notebook at this time to the notebook, and assuming that the power allocated to the notebook at this time is P5, the power left by the docking station in the case of accessing only the notebook is (P4-P5).
Under the condition that the first interface-USB-c interface is connected with the notebook computer, a second electric device such as a mobile phone is connected into the docking station through the second interface-USB-c interface. Under the condition that the second interface is accessed with equipment or is not accessed with equipment, the signal level on the interface is different, for example, under the condition that the equipment is not accessed, the signal level is 0, and under the condition that the equipment is accessed, the signal level is 1; and vice versa. The MCU detects the signal level of the second interface, when the signal level is changed from 0 to 1, the first signal, namely a signal that the second electric device is connected into the docking station, the controller is informed that the docking station has another electric device except the notebook, and the MCU can distribute power information (P4-P5) left by the docking station except the electric quantity distributed for the notebook directly to the mobile phone.
In addition, the controller may also know the power required by the second access device, i.e., the handset, based on the PD protocol, and inform the MCU of the known power. The MCU calculates power information (P4-P5) remaining by the docking station except for power allocated to the notebook before the handset is accessed, and determines power to the handset according to the power information required by the handset. It is understood that there are two situations at this time:
the first situation is as follows: and if the power required by the mobile phone is more than or equal to the residual power except the power required by supplying power to the notebook computer, the MCU distributes the residual power to the mobile phone to supply power to the mobile phone.
Case two: and if the power required by the mobile phone is less than the residual power except the power required by the power supply of the notebook computer, the MCU extracts the power required by the mobile phone from the residual power to the mobile phone so as to safely supply the power to the mobile phone.
Based on the foregoing solution, for the first device, i.e. the first electric device, connected to the docking station, the docking station supplies power to the first electric device with the power required by the first electric device, and when the second device is connected, the docking station supplies power to the second access device or supplies power required by the second access device with the remaining power except for the power required by the first access device, thereby realizing balanced power supply to the two access devices. The docking station can use the power required by the first access device to supply power or provide the maximum power which can be provided by the first access device, so that the charging time of the first access device can be at least shortened, the power supply of the first access device is preferentially ensured, and the scheme of preferentially supplying power to the power-consuming device which is accessed in advance is provided.
In addition, under the condition that the first interface-USB-c interface is connected with an electric device, the second electric device is connected with the second interface, the power required by the first electric device and the power required by the second electric device are compared, if the power required by the second electric device is larger than the power required by the first electric device, the MCU provides P4 power or the power required by the second electric device for the second electric device, and the remaining power or the power required by the first electric device is extracted from the remaining power to the first electric device to supply power to the first electric device, so that balanced power supply of the two connected devices is realized. It can be understood that, in this case, it is equivalent to that the power of the first electrical device is adjusted when the second electrical device is connected, and the adjustment of the power supply parameter of the electrical device is realized at an appropriate adjustment timing.
It can be understood that the embodiment of the present application may be a balanced power supply to two access devices, or may also be a priority power supply to an electric device that is accessed first.
In the process that the docking station supplies power to two access devices, such as the aforementioned first access device, namely the notebook computer and the second access device, namely the mobile phone, if at least one of the following conditions exists, the MCU detects an adjustment signal (a signal that changes the power supply parameter of the first access device and/or a signal that changes the power supply energy output by the adapter to the docking station), and the MCU readjusts the amount of power supplied to the first access device, such as power (a second parameter), according to the actual condition, and readjusts the amount of power supplied to the second access device according to the adjustment of the amount of power supplied to the first access device.
The first condition is as follows: from the perspective of the first access device, the following three cases are divided;
(1) the powered state of the first access device, such as a notebook computer, changes;
A. before adjusting the second parameter of the first access device, such as a laptop, the first access device may be in one of the following three states: a charged only state, an operated only state, and a charged + operated state. When such a state is changed, i.e. when switching from one of the above states to one of the other two states, the amount of power supply to the first access device needs to be readjusted.
Case where the state is changed:
for example, assuming that before the readjustment, the first access device only needs to be powered, is not powered on and does not need to maintain operation, the first access device is powered on when the user needs to use the first access device, the first access device is switched from an inactive state to an active state (the operation of the device needs to consume power), and the power-on operation of the first access device is equivalent to switching the first access device from an original state that only needs to be powered on to a state that needs to be powered on and maintain normal operation of the first access device. Assuming that P0, P1, and P2 are all unchanged, the switching of the state corresponds to an increase in power consumption of the first access device compared with a state in which power needs to be supplied only, and the MCU extracts power required by the first access device from P4 to supply power to the first access device. Then, after the power supply amount provided for the first access equipment is removed, the remaining power is used for supplying power for the second access equipment according to one of the first and second situations; the increased power consumption of the first access device results in a possibility that the power supply to the second access device may be reduced, depending on one of the two aforementioned situations.
For example, before adjusting the second parameter of the first access device, the first access device needs to be powered and operated, and when the operation is finished, the first access device is switched from being operated + charged to being charged only. Assuming that P0, P1, and P2 are all unchanged, the switching of this state corresponds to a reduction in power consumption of the first access device, and naturally, the docking station may increase the power supply amount to the second access device after switching in addition to the power supply amount for the first access device compared to before switching.
For example, the first access device is in a charged or both charged and operating state before the second parameter of the first access device is adjusted. The MCU estimates a charging time (first information) of the first access device, and switches to a fully charged state or only an operated state when the estimated charging time reaches or detects completion of charging. In this case, the power consumption of the first access device is reduced, and naturally, the docking station can provide more power to the second access device, and the specific power to be used for powering the second access device depends on one of the two situations.
b. A first access device, such as a laptop computer, is moved from a connected state to a removed state or vice versa;
before adjusting the second parameter of the first access device, the first access device is removed from the docking station assuming the first access device is in a charged state, the power is fully charged or there are other circumstances such as a user may have an urgency to temporarily disconnect the charging using the first access device. I.e., the first access device is switched from being connected to the docking station to be powered to being disconnected from the docking station, the amount of power supplied to the first access device needs to be readjusted, it is understood that the second parameter in this case is usually changed from a non-zero value to a zero value, and assuming that P0, P1 and P2 are all unchanged, the docking station can provide the second access device with its required amount of power from P4.
c. A first access device such as a notebook computer is charged from incomplete to complete;
before adjusting the second parameter of the first access device, assuming that the first access device is in a charged state, in the process of charging the first access device, the MCU estimates a charging time of the first access device or detects whether a charging completion event occurs, when the charging time arrives, the MCU is fully charged, and switches from the charging incomplete state to the charging complete state, requiring readjustment of the power supply amount to the first access device. It is understood that the above readjustment of the power supply amount to the first access device, based on the adjustment, the power supply amount to the second access device is also adjusted as it occurs.
(2) The presence or removal of other power supplies besides the docking station exists in the first access device such as a notebook computer;
before adjusting the second parameter of the first access device, the first access device may have other power sources to power it besides the docking station, in which case the amount of power allocated to it by the docking station should be equal to the amount of power it needs-the other power sources can provide. Assuming that the power supply of the first access device is changed from multiple to fewer in the case of no change in P0, P1, and P2, the docking station needs to increase its power supply to ensure that it is powered preferentially, and naturally, the amount of power that the docking station can provide to the second access device is reduced, and how much power the docking station outputs to the second access device depends on the above-mentioned condition one or two.
It will be appreciated that the first access device may also switch from having no power supply other than the other docking station to having another power supply to begin powering it, in which case the docking station may reduce its amount of power, the amount of power that the docking station can provide to the second access device may be greater, and how much power needs to be output to the second access device may depend on one or both of the aforementioned situations.
(3) It is understood that the first electrical device may be a device such as a peripheral connected to the fourth interface, in addition to the electrical device connected to the first interface (the first access device). The fourth interface increases the number of peripherals from the original state where no peripheral is connected to the connected peripheral, changes the number of peripherals from the connected peripheral to the removed peripheral (P2), or decreases the number of peripherals. In these cases, corresponding to the case that P2 of P4-P0-P1-P2 (assuming that P0 and P2 are not changed) is increased or decreased, naturally, the amount of power that the docking station can supply to the first and second access devices is increased or decreased, and the power that at least one of the first and second electrical devices can use is changed accordingly.
Case two: from the power consumed by the docking station itself:
in case the power P0 input by the adapter to the docking station is changed, the power supply to the first and second access devices needs to be readjusted. In actual application, different adapters have different power P0, and in case of adapter replacement, P0 is changed. Assuming that both P1 and P2 are unchanged, the power P4 provided by the docking station to the first and second access devices increases or decreases, and naturally, the power that can be used by at least one of the first and second electrical devices changes accordingly. For example, the power used by the first electrical device is unchanged and the power used by the second electrical device is increased or decreased. Alternatively, the power used by both the first and second electrical devices may be increased or decreased.
The power (P1) of the docking station maintaining its operation changes, such as increases or decreases, such as the circuitry in the docking station maintaining its operation wakes up more and more or less. Assuming that both P0 and P2 are unchanged, the power P4 provided by the docking station to the first and second access devices increases or decreases, and naturally, the power that can be used by at least one of the first and second electrical devices changes accordingly.
It can be understood that the power that at least one of the first and second electrical devices can use changes with the occurrence of a change, and for how to change, please refer to the foregoing description of the first time the access device accesses the docking station for understanding, and details are not repeated.
In the foregoing aspect, the readjustment of the power supply amounts (second parameters) output to the first and second access devices is realized based on various conceivable situations, and thus the adjustment of the power supply amounts at appropriate adjustment timings is realized. It can be understood that in the scheme, no matter the scheme of preferentially ensuring power supply to the first accessed device in the notebook computer and the mobile phone or the scheme of carrying out balanced power supply to the notebook computer and the mobile phone, the two accessed devices can be supplied with non-fixed power supply amount, the power supply mode is flexible, and the two accessed devices can be fully charged as soon as possible. The adjustment of the power supply output to the second access equipment is carried out according to the adjustment of the power supply output to the first access equipment, so that the leading position of the first access equipment can be preferentially ensured, and the first access equipment can accelerate the completion of charging.
It can be understood that, in the foregoing embodiment, the power supply parameter (first parameter) that the electronic device can output to the electric device, the power supply parameter (second parameter) of the electronic device to the first electric device, and the power supply parameter (third parameter) that the electronic device needs to the second electric device may be obtained by the electronic device at the adjustment timing when the predetermined condition is met to obtain the trigger instruction, or some of the parameters may be obtained at the adjustment timing when the trigger instruction is obtained, and other parameters are obtained before the trigger instruction is obtained. For example, if the electronic device has been connected to a laptop and a mobile phone, and the predetermined condition is that it is detected that the laptop is switched from a charging incomplete state to a charging complete state, the second parameter is obtained at the adjustment time, and the first parameter and the third parameter take the previous values.
It is understood that the foregoing solution describes as many cases as possible of the power of the first and second access devices being readjusted, and moreover, any other cases that are not mentioned herein but are reasonable and that can be readjusted are within the scope of the present application.
