Detailed Description
Referring now to the drawings, in which like numerals represent like elements, the principles of the present invention are illustrated as being implemented in a suitable computing environment. The following description is based on illustrated embodiments of the invention and should not be taken as limiting the invention with regard to other embodiments that are not detailed herein.
It is understood that the execution subject of the embodiment of the present application may be a wireless charging transmission device.
Referring to fig. 1, fig. 1 is a schematic flowchart of a wireless charging method according to an embodiment of the present disclosure, where the flowchart may include:
in 101, when at least two wireless charging receiving devices need to be wirelessly charged, the number of the wireless charging receiving devices is acquired.
With the continuous development of the technology, more and more electronic devices are applied to remote wireless charging. Remote wireless charging refers to the transmission of electrical energy through a non-conductive substance for a certain spatial distance. The remote wireless charging system comprises a wireless charging transmitting device and a wireless charging receiving device. In the related art, the power supply efficiency of the wireless charging transmitting device is low when the wireless charging transmitting device wirelessly charges a plurality of wireless charging receiving devices in a long distance.
In 101 of the present application, for example, in the case of performing long-distance wireless charging, when it is detected that at least two wireless charging receiving devices need to be wirelessly charged, the wireless charging transmitting device may first acquire the number of the wireless charging receiving devices.
At 102, a charge parameter value of each wireless charging reception device is obtained.
For example, after the number of the wireless charging receiving devices is obtained, the wireless charging transmitting device may obtain the electric quantity parameter value of each wireless charging receiving device. The power parameter value refers to a parameter value related to power, such as a remaining power value or a power consumption rate. The charge parameter value may be used to characterize the actual charging requirements of the wireless charging receiving device.
In 103, the charging power allocated to each wireless charging receiving device is determined according to the number of the wireless charging receiving devices and the electric quantity parameter value of each wireless charging receiving device.
For example, after the number of the wireless charging receiving devices and the electric quantity parameter value of each wireless charging receiving device are obtained, the wireless charging transmitting device may determine the charging power allocated to each wireless charging receiving device according to the number of the wireless charging receiving devices and the electric quantity parameter value of each wireless charging receiving device.
And in 104, wirelessly charging the wireless charging receiving equipment according to the determined charging power.
For example, after determining the charging power allocated to each wireless charging receiving device, the wireless charging transmitting device may wirelessly charge each wireless charging receiving device accordingly.
For example, currently, the wireless charging transmitting device receives 3 wireless charging requests from the wireless charging receiving device, that is, the wireless charging transmitting device needs to wirelessly charge 3 wireless charging receiving devices currently. At this time, the wireless charging transmission device may acquire the number of wireless charging reception devices, for example, the number is 3. And then, the wireless charging transmitting equipment can acquire the electric quantity parameter value of each wireless charging receiving equipment. For example, the charge parameter value may be a remaining charge value or a charge consumption rate within a preset time range, or the like. And then, the wireless charging transmitting equipment can determine the charging power distributed to each wireless charging receiving equipment according to the number of the wireless charging receiving equipment and the electric quantity parameter value of each wireless charging receiving equipment. For example, the wireless charging reception device includes A, B, C. The wireless charging transmitting device can provide 20W of supply power at most. The wireless charging transmitting device determines to allocate 8W of charging power to the wireless charging receiving device a, 6W of charging power to the wireless charging receiving device B and 6W of charging power to the wireless charging receiving device C according to the residual electric quantity value of the wireless charging receiving device A, B, C. After the charging power distributed to each wireless charging receiving device is determined, the wireless charging transmitting device can wirelessly charge each wireless charging receiving device according to the determined charging power. That is, the wireless charging transmitting apparatus may charge the wireless charging receiving apparatus a with a charging power of 8W, charge the wireless charging receiving apparatus B with a charging power of 6W, and charge the wireless charging receiving apparatus C with a charging power of 6W.
It can be understood that, in the embodiment of the present application, when the wireless charging transmitting device needs to charge at least two wireless charging receiving devices, the wireless charging transmitting device may determine, according to the number of the wireless charging receiving devices and the parameter value of the electric quantity of each wireless charging receiving device, the charging power allocated to each wireless charging receiving device, and charge each wireless charging receiving device according to the determined charging power. Compared with the prior art, when at least two wireless charging receiving devices need to be charged, the power supply efficiency of the wireless charging transmitting device is low because the wireless charging transmitting device is difficult to determine the charging power distributed to each wireless charging receiving device, and the embodiment can quickly determine the charging power distributed to each wireless charging receiving device according to the number of the wireless charging receiving devices and the electric quantity parameter values of each wireless charging receiving device, so the power supply efficiency of the wireless charging transmitting device can be improved. In addition, the embodiment can also improve the power supply flexibility of the wireless charging transmitting device when at least two wireless charging receiving devices need to be remotely and wirelessly charged.
Referring to fig. 2, fig. 2 is another schematic flow chart of a wireless charging method according to an embodiment of the present disclosure, where the flow chart may include:
in 201, when at least two wireless charging receiving devices need to be wirelessly charged, the wireless charging transmitting device acquires the number of the wireless charging receiving devices.
For example, when it is detected that at least two wireless charging receiving devices need to be wirelessly charged, the wireless charging transmitting device may first acquire the number of the wireless charging receiving devices.
In 202, the wireless charging transmitting device obtains a remaining electric quantity value of each wireless charging receiving device.
For example, after the number of the wireless charging receiving devices is obtained, the wireless charging transmitting device may obtain the remaining electric quantity value of each wireless charging receiving device.
After that, the wireless charging transmitting device may detect whether the number of the wireless charging receiving devices is less than or equal to a preset value. In one embodiment, the preset value may be a number supported by the wireless charging transmitting device that can charge the wireless charging receiving device at most at the same time. For example, when the wireless charging transmitting device can wirelessly charge 5 wireless charging receiving devices at most simultaneously, the preset value is 5. Or, when the wireless charging transmitting device can wirelessly charge 8 wireless charging receiving devices at most at the same time, the preset value is 8, and so on.
If the number of the wireless charging receiving devices is detected to be smaller than or equal to the preset value, the process proceeds to 203.
If the number of the wireless charging receiving devices is detected to be larger than the preset value, the process proceeds to step 206.
In 203, if the number of the wireless charging receiving devices is less than or equal to the preset value, the wireless charging transmitting device detects whether the remaining electric quantity values of the wireless charging receiving devices are all greater than or equal to the preset second electric quantity threshold.
For example, the number of wireless charging receiving devices to be charged is 4, and the preset value is 5. Then, the wireless charging transmitting device may detect that the number of wireless charging receiving devices is less than a preset number. At this time, the wireless charging transmitting device may detect whether the remaining power values of the wireless charging receiving devices are all greater than or equal to the preset second power threshold.
In some embodiments, the preset second charge threshold may be, for example, 50% or 60%, etc.
If the detected remaining electric quantity value of each wireless charging receiving device is greater than or equal to the preset second electric quantity threshold value, the remaining electric quantity of each wireless charging receiving device can be considered to be sufficient. In this case, 204 may be entered.
If it is detected that the remaining power values of the wireless charging receiving devices are not all greater than or equal to the preset second power threshold, it can be determined that the remaining power of some wireless charging receiving devices is sufficient, and the remaining power of some wireless charging receiving devices is low. In this case, 205 may be entered.
In 204, if the remaining power value of each wireless charging receiving device is greater than or equal to the preset second power threshold, the wireless charging transmitting device distributes the provided charging power equally among the wireless charging receiving devices.
For example, when the wireless charging transmitting device detects that the remaining power value of each wireless charging receiving device is greater than or equal to the preset second power threshold, the wireless charging transmitting device may equally distribute the charging power provided by the wireless charging transmitting device among the wireless charging receiving devices.
For example, the maximum charging power that the wireless charging transmitting device can provide is 20W, the number of the wireless charging receiving devices is 4, and the remaining power values of the wireless charging receiving devices are all greater than the preset 50%, then the wireless charging transmitting device can distribute 20W of charging power to the 4 wireless charging receiving devices on average, that is, each wireless charging receiving device can distribute 5W of charging power. And then into 209.
In 205, if the remaining power values of the wireless charging receiving devices are not all greater than or equal to the preset second power threshold, the wireless charging transmitting device performs non-average distribution of the provided charging power among the wireless charging receiving devices, wherein the lower the remaining power value is, the larger the charging power distributed to the wireless charging receiving devices is.
For example, when the wireless charging transmitting device detects that the remaining power values of the wireless charging receiving devices are not all greater than or equal to the preset second power threshold, the wireless charging transmitting device may distribute the charging power provided by the wireless charging transmitting device non-equally among the wireless charging receiving devices.
For example, the maximum charging power that the wireless charging transmitting device can provide is 20W, and the number of the wireless charging receiving devices is 4, for example, the 4 wireless charging receiving devices are A, B, C, D respectively. Wherein, the residual electric quantity value of A is 60%, the residual electric quantity value of B is 65%, and the residual electric quantity values are both larger than the preset 50%. And the residual electric quantity value of C is 45%, the residual electric quantity value of D is 30%, and the residual electric quantity values are both less than the preset 50%. Then the wireless charging transmitting device may distribute 20W of charging power non-evenly among the 4 wireless charging receiving devices. Wherein the device with the smaller residual electric quantity value distributes the larger charging power. For example, A, B, C, D allocates charging power of 4W, 6W in sequence, or A, B, C, D allocates charging power of 4W, 3W, 5W, 8W in sequence, and so on. And then into 209.
In 206, if the number of the wireless charging receiving devices is greater than the preset value, the wireless charging transmitting device determines a charging sequence of the wireless charging receiving devices according to a time sequence that each wireless charging receiving device sends a charging request to the wireless charging transmitting device.
For example, the number of wireless charging receiving devices to be charged is 8, and the preset value is 5. Then, the wireless charging transmitting device may detect that the number of the wireless charging receiving devices is greater than a preset value. Since the wireless charging transmitting device can only charge 5 wireless charging receiving devices at most at the same time, the wireless charging transmitting device can only charge part of the wireless charging receiving devices first, and the other part of the wireless charging receiving devices need to wait temporarily until the wireless charging transmitting device can charge the wireless charging receiving devices. At this time, the wireless charging transmitting device may determine the charging sequence of the wireless charging receiving devices according to the time sequence of the charging requests sent by the wireless charging receiving devices to the wireless charging transmitting device.
And then, the wireless charging transmitting equipment can sequentially charge the wireless charging receiving equipment according to the determined charging sequence.
It can be understood that, in this embodiment, a charging sequence may be determined for the wireless charging receiving device, so that efficiency and flexibility of the wireless charging transmitting device for performing long-distance wireless charging may be further improved.
In 207, when the wireless charging receiving device is charged according to the charging sequence, if the remaining electric quantity values of the target devices are all greater than or equal to the preset second electric quantity threshold, the wireless charging transmitting device equally distributes the provided charging power among the target devices, where the target devices are the device undergoing wireless charging and the device beginning to undergo wireless charging.
For example, when the wireless charging receiving device is charged according to the determined charging sequence, the wireless charging transmitting device may detect whether the remaining electric quantity values of the target device are all greater than or equal to the preset second electric quantity threshold. Wherein the target device comprises a device that is performing wireless charging and that starts performing wireless charging.
For example, 8 wireless charging receiving devices to be charged are A, B, C, D, E, F, G, H in sequence according to the charging sequence, that is, the charging sequence of a is arranged at the first position, the charging sequence of B is arranged at the second position, and so on, and the charging sequence of H is arranged at the eighth position. For example, the wireless charging transmitting device may first charge A, B, C, D, E. After a while, the device a is charged, and at this time, the wireless charging transmitting device may start to charge F, that is, the device being charged is B, C, D, E, and the device starting to charge is F. That is, at this time, the device B, C, D, E, F is the target device.
If the detected remaining electric quantity values of the target devices are all larger than or equal to the preset second electric quantity threshold value, the remaining electric quantity values of the target devices can be considered to be all sufficient, and at the moment, the wireless charging transmitting device can equally distribute the provided charging power among the target devices. For example, the wireless charging transmitting device can provide 20W of charging power at the maximum, and then the wireless charging transmitting device can allocate 4W of charging power to the devices B, C, D, E, F. And then into 209.
In 208, when the wireless charging receiving devices are charged according to the charging sequence, if the remaining power values of the target devices are not all greater than or equal to the preset second power threshold, the wireless charging transmitting device performs non-average distribution of the provided charging power among the target devices, wherein the lower the remaining power value, the larger the charging power distributed by the wireless charging receiving devices is.
For example, if the wireless charging and transmitting device detects that the remaining electric quantity values of the target devices are not all greater than or equal to the preset second electric quantity threshold, it may be considered that the remaining electric quantity values of some target devices are smaller. At this time, the wireless charging transmitting device may distribute the provided charging power unevenly among the target devices, wherein the lower the remaining power value, the greater the charging power distributed to the wireless charging receiving device. For example, the wireless charging transmitting device can provide 20W of charging power at maximum, and the remaining electric quantity value of the device B, C, D, E, F is 80%, 90%, 70%, 60% and 40% in sequence. Then, the charging power allocated to B, C, D, E, F by the wireless charging transmitting device at this time may be 3W, 2W, 3W, 5W, 7W in sequence. Alternatively, the charging power allocated to B, C, D, E, F by the wireless charging transmitting device may be 3W, 5W, 6W, and so on. And then into 209.
In 209, the wireless charging transmitting device wirelessly charges the wireless charging receiving device according to the determined charging power.
For example, after determining the charging power allocated to each wireless charging receiving device, the wireless charging transmitting device may perform wireless charging on the wireless charging receiving device according to the determined charging power.
In an implementation manner, this embodiment may further include the following process:
when the number of the wireless charging receiving devices needing to be charged is larger than a preset value, if a charging request of a first device is received, the wireless charging transmitting device determines a second device from the devices which are being charged, wherein the residual electric quantity value of the first device is smaller than a preset first electric quantity threshold value;
the wireless charging transmitting device suspends wireless charging of the second device and initiates wireless charging of the first device.
For example, the wireless charging transmitting device is wirelessly charging B, C, D, E, F, and the wireless charging receiving devices G and H are in a state of waiting for charging. If the wireless charging transmitting device receives the charging request of the wireless charging receiving device I and detects that the remaining electric quantity value of I is smaller than the preset first electric quantity threshold, the wireless charging transmitting device may determine the second device from the devices B, C, D, E, F that are being charged. Thereafter, the wireless charging transmitting device may suspend wireless charging of the second device and initiate wireless charging of the first device.
For example, the value of the remaining power of the device I is only 3%, and the preset first power threshold value is 5%, that is, the remaining power of the device I is very low. In this case, in order to avoid automatic shutdown of the device I when its power level drops to zero due to too long time spent waiting for charging in line, the wireless charging transmitting device may determine the second device from the devices B, C, D, E, F that are being charged, suspend charging of the second device, and add the device I to the charging queue. For example, the wireless charging transmitting device may determine the device C with the largest remaining amount of power in the charging devices B, C, D, E, F as the second device, suspend charging of the device C, initiate charging of the device I, and so on.
In one embodiment, the wireless charging transmitting device may suspend charging of the first device and restart charging of the second device after charging the first device to a predetermined charge value. For example, after charging device I from a 3% remaining power value to a 10% remaining power value, the wireless charging transmitting device may suspend charging of device I and restart charging of device C.
In another embodiment, the wireless charging transmitting device may further estimate (budget) a charging queue waiting time period according to the remaining electric quantity values of the charging device and the charging-waiting device and the charging power corresponding to each device, and estimate a target electric quantity that needs to be consumed by the first device during the period of the charging queue waiting time period. Then, the wireless charging transmitting device may restart charging the second device after charging the target amount of power for the first device. For example, under the condition that the first device is not added into the charging queue in advance, it is estimated that the first device needs to wait for 30 minutes to start charging, and it is estimated that the first device needs to consume 8% of the electric quantity in 30 minutes, after the first device is added into the charging queue in advance, after the first device is charged with 8% of the electric quantity, the charging of the first device is suspended, and the charging of the second device is restarted.
In another embodiment, in this embodiment, the parameter value of the power amount in the process 102 may also be a power consumption speed of the wireless charging receiving device within a preset time range. When the value of the power parameter is the power consumption rate, the wireless charging transmitting device in the process 202 may obtain the power consumption rate of the wireless charging receiving device within the preset time range.
Then, when it is detected that the power consumption speeds of the wireless charging receiving devices are all less than or equal to the preset speed, it can be determined that the power consumption speeds of the wireless charging receiving devices all meet the preset condition, and at this time, the wireless charging transmitting device can equally distribute the charging power provided by the wireless charging transmitting device among the wireless charging receiving devices. When it is detected that the electric quantity consumption speeds of the wireless charging receiving devices are not all smaller than or equal to the preset speed, it can be determined that the electric quantity consumption speeds of the wireless charging receiving devices do not all meet the preset condition, and at this time, the wireless charging transmitting device can perform non-average distribution on the charging power provided by the wireless charging transmitting device among the wireless charging receiving devices.
Referring to fig. 3 to 5, fig. 3 to 5 are schematic views of a wireless charging method according to an embodiment of the present disclosure.
For example, as shown in fig. 3, a wireless charging transmitting device 10 is provided on a ceiling in a room in which a table 20 is provided, and the table 20 is located within a charging range of the wireless charging transmitting device 10. That is, when a user places a device, such as a smartphone or tablet, on the table, the smartphone or tablet may receive power from the wireless charging transmitting device and use the power to charge the battery.
For example, as shown in fig. 3, the user places 4 devices to be wirelessly charged on a table, for example, the 4 wireless charging receiving devices are 31, 32, 33, and 34, respectively. When the user places these 4 wireless charging reception devices on a desk, these devices respectively transmit a charging request to the wireless charging transmission device 10. That is, at this time, the wireless charging transmitting device needs to wirelessly charge 4 wireless charging receiving devices. The maximum charging power that the wireless charging transmitting device can provide is 20W, and the wireless charging transmitting device can wirelessly charge 5 wireless charging receiving devices at most simultaneously. In this case, the wireless charging transmission device may acquire the remaining power values of the wireless charging reception devices 31, 32, 33, 34, respectively, and detect whether the remaining power values of the wireless charging reception devices 31, 32, 33, 34 are all greater than or equal to a preset 50%.
For example, in this embodiment, the remaining electric power values of the wireless charging receiving devices 31, 32, 33, and 34 are all greater than the preset 50%, in which case, the wireless charging transmitting device may equally distribute the charging power provided by the wireless charging receiving devices 31, 32, 33, and 34. For example, the wireless charging transmission device may allocate charging power of 5W to each of the wireless charging reception devices 31, 32, 33, 34.
After a while, the user places another wireless charging receiving device 35 on the desk, that is, the wireless charging transmitting device needs to charge 5 wireless charging receiving devices, as shown in fig. 4. For example, the remaining electric quantity value of the wireless charging receiving device 35 in the present embodiment is also greater than 50%. Then, since a new wireless charging reception device is added to the charging queue, the wireless charging transmission device may reallocate charging power to each wireless charging reception device. For example, at this time, the wireless charging transmitting device may allocate 4W of charging power to each of the wireless charging receiving devices 31, 32, 33, 34, 35.
For example, as shown in fig. 5, in another scenario, the wireless charging transmitting device 10 receives a charging request of the wireless charging receiving devices 31, 32, 33, 34, 35, 36, 37 in a short time. Because the wireless charging transmitting equipment can only charge 5 wireless charging receiving equipment at most at the same time, the wireless charging transmitting equipment can determine the charging sequence of each wireless charging receiving equipment according to the time sequence of the charging requests sent by each wireless charging receiving equipment to the wireless charging transmitting equipment. For example, the wireless charging transmitting device determines the charging sequence to be the wireless charging receiving devices 31, 32, 33, 34, 35, 36, 37 in order from front to back. That is, the wireless charging transmitting device first wirelessly charges the wireless charging receiving devices 31, 32, 33, 34, 35.
For example, in this embodiment, if the wireless charging transmitting device detects that the remaining electric power values of the wireless charging receiving devices 31, 32, 33, 34, and 35 are all greater than the preset threshold, the wireless charging transmitting device may equally distribute the charging power provided by the wireless charging transmitting device among the wireless charging receiving devices 31, 32, 33, 34, and 35. For example, the wireless charging transmission device may allocate 4W of charging power to each of the wireless charging reception devices 31, 32, 33, 34, 35. If the wireless charging transmitting device detects that the remaining charge values of the wireless charging receiving devices 31, 32, 33, 34, 35 are not all greater than the preset threshold, the wireless charging transmitting device may distribute the charging power provided by the wireless charging transmitting device non-equally among the wireless charging receiving devices 31, 32, 33, 34, 35. For example, the wireless charging transmitting device may allocate charging power for the wireless charging receiving devices 31, 32, 33, 34, 35 of 3W, 2W, 3W, 5W, and 7W in this order.
After several minutes, the wireless charging receiving device 32 is charged, and the wireless charging transmitting device can start to wirelessly charge the wireless charging receiving device 36.
