All the above optional technical solutions may be combined arbitrarily to form the optional embodiments of the present disclosure, and are not described herein again.

Fig. 2 is a flowchart illustrating a charging method according to an exemplary embodiment, which is used in the wireless charging device, as shown in fig. 2, and includes the following steps.

In step 201, the wireless charging device determines a current geographic location of the wireless charging device, obtains marking information and marking range data input by a user, and marks the geographic location according to the marking information and the marking range data to obtain a marked area.

The wireless charging technology utilizes magnetic resonance to transmit electric energy in an electric field and a magnetic field between the wireless charging device and the terminal, and the coil and the capacitor form resonance between the wireless charging device and the terminal. That is, the resonance principle used by the wireless charging device is magnetic field resonance, and electric energy is transmitted only between coils resonating at the same frequency, which is unacceptable for other terminals. The Wireless charging device may be connected to a WLAN (Wireless Local Area network) for data transmission. Various terminals of a user, such as a smart phone, a tablet computer and the like, can be connected with the wireless charging device through a wireless network. When determining the current geographic location of the wireless charging device, the wireless charging device may be implemented by a GPS (Global Positioning System) technology or a WLAN, which is not specifically limited in this disclosure.

The marking information input by the user may be "home", "company", "school", and the like, and is used to mark a place where the user frequently appears, and this is not specifically limited in the embodiment of the present disclosure. The marking range data is used for marking a radius of a geographic location where the wireless charging device is currently located. For example, the tag range data may be 10 meters. Taking a home as an example, the radius of the home area is about 10 meters. When any terminal of the user is 10 meters away from the current geographical position of the wireless charging device, that is, the terminal is not in the room, the user may have carried the terminal out.

After the geographical position is marked according to the marking information and the marking range data to obtain a marking area, the marking area is a circular area which takes the geographical position of the wireless charging device as the center and takes the marking range data as the radius. The wireless charging apparatus may record position information, mark radius information, and the like of the mark area.

In step 202, the wireless charging device receives the position change instruction, counts the time when each terminal leaves the mark area according to the position change instruction, and establishes a corresponding relationship between the identity of the terminal and the time when the terminal leaves the mark area.

In the embodiment of the disclosure, the network module is built in the wireless charging device, so that the wireless charging device can be connected with the router, and can also be connected with each terminal of the user. If the geographic position of the wireless charging device is unchanged within a certain period of time, the time of each terminal leaving the marking area can be counted through counting within a period of time. For example, the user of the wireless charging device is always at home, the user usually carries a mobile phone, a tablet computer, a smart watch and the like when going out to work or studying every day, and the time of the user going out to work or studying every day is usually fixed, so that the time of each terminal leaving the marked area can be summarized through continuous statistics of a period of time.

The location change instruction received by the terminal may be sent by the terminal itself or sent by the router, and the details are as follows:

in the first method, after the terminal leaves the mark area, the terminal itself sends a position change instruction.

For the first mode, since each terminal may establish a connection with the wireless charging device through the wireless network, each terminal and the wireless charging device may perform data transmission through the wireless network. For example, each terminal acquires geographical location information of the wireless charging device, tag information of a tag area, tag range data, and the like through a wireless network. When any terminal moves, a GPS module arranged in the terminal can acquire the position information of the terminal in real time; when the distance between the current position of the terminal and the geographic position of the wireless charging equipment is larger than the size of the marking radius, the terminal is proved to leave the marking area at the moment, and the terminal is triggered to send a position change instruction to the wireless charging equipment. The location change instruction at least includes a time when the terminal leaves the mark area and an identity of the terminal, which is not specifically limited in the embodiment of the present disclosure. The identity may be a media access control address of the terminal or a terminal name, and the like, which is also not specifically limited in this disclosure.

In the second method, after the terminal leaves the mark area, the router which establishes connection with the terminal sends a position change instruction.

In the second method, since each terminal is usually connected to a router located in the label area, such as a home, an office, or other public place, it is also possible to determine whether or not the terminal leaves the label area from the perspective of the router. Because the wireless network coverage of the router is limited, when the distance between the router and the terminal exceeds a certain value, the router and the terminal can be automatically disconnected. Therefore, the router can detect whether there is a terminal disconnected from the network in real time or at preset time intervals. When any terminal is disconnected from the terminal, a position change instruction about the terminal is sent. The location change instruction at least includes a time when the terminal leaves the mark area and an identity of the terminal, which is not specifically limited in the embodiment of the present disclosure.

After the wireless charging equipment receives the position change instructions, the time of each terminal leaving the marking area is counted according to the position change instructions. For any terminal, when counting the time when the terminal leaves the marked area, because the time when the terminal leaves the marked area each time may be slightly different, the time when the terminal is more prone to leave can be determined in a plurality of leaving times, and the time when the terminal leaves the marked area can be calculated according to the time. For example, if the user goes out with the terminal at about 8 am, the time when the terminal is more likely to leave the marked area is about 8 am, and if the terminal leaves at 13 pm or later, the corresponding leaving time can be discarded. But is based on a plurality of departure times around 8 points. And then, the wireless charging equipment establishes a corresponding relation between the identity of the terminal and the time of leaving the marking area. Taking the id as the mac address, a mapping table as shown in table 1 below may be established.

TABLE 1

ID	Time of departure
		00-23-5A-15-99-42	8:00
10-4F-50-45-10-23	13:23
		……	……

19:45

In step 203, when the wireless charging device detects that it establishes connection with a plurality of terminals, a second charging time consumed by each terminal to be charged from a zero charge amount to a full charge amount when the charging power is evenly distributed is calculated.

In the embodiment of the disclosure, after the terminal is connected to the wireless charging device, the wireless charging device reads the identity of the terminal. If the wireless charging device judges that only one terminal is connected with the wireless charging device according to the identifier, the step and the subsequent steps do not need to be executed, and the processing flow is ended. If the wireless charging device judges that a plurality of current terminals are connected with the wireless charging device according to the device identifier, the charging power is distributed to each terminal according to the method provided by the embodiment of the disclosure. First, it is assumed that the second charging time pt (power time) consumed when each terminal is charged from zero charge to full charge is the case where the charging power is equally allocated to the plurality of terminals. The calculation of the second charging time may be implemented by referring to the prior art, which is not described in detail in the embodiments of the present disclosure.

In step 204, the wireless charging device obtains the current available power of each terminal, and calculates a first charging time consumed by each terminal when the current available power of each terminal is charged to full power according to the current available power of each terminal and the second charging time.

In the embodiment of the present disclosure, after reading the identity of each terminal, the wireless charging device will also read the current available power of each terminal in sequence. In the embodiment of the present disclosure, the currently available electric quantity is characterized in a percentage form, and is denoted as ap (available power). Of course, the currently available power may be characterized in other forms, and this is not particularly limited in the embodiments of the present disclosure. Then, the wireless charging device calculates a first charging time PT1 consumed by each terminal from the current available power amount AP to full charge according to the current available power amount AP and the second charging time PT of each terminal. Wherein,

PT1＝PT*(1-AP) (1)

in step 205, the wireless charging device obtains the time that each terminal leaves the tag area, which is counted in advance, based on the correspondence between the identity of the terminal and the time that the terminal leaves the tag area.

In the embodiment of the present disclosure, when acquiring the time that each terminal leaves the mark area, which is counted in advance, the wireless charging device may implement the following steps: for each terminal, according to the identity of the terminal, searching is performed in the corresponding relationship shown in the table 1, so as to obtain a time value matched with the identity, and the time value is determined as the time when the terminal leaves the mark area.

Of course, besides the above-mentioned manner of obtaining the time when each terminal leaves the mark area, other manners may also be adopted, and this is not specifically limited in this embodiment of the disclosure.

In step 206, the wireless charging device calculates an actual charging time of each terminal according to the first charging time, the current time and the time when each terminal leaves the mark area.

When the actual charging time of each terminal is calculated according to the first charging time, the current time and the time when each terminal leaves the mark area, the following method can be adopted:

for each terminal, calculating a time difference T1 between the time T when the terminal leaves the marking area and the current time TC; when the first charging time PT1 is less than the time difference T1, the first charging time is determined as the actual charging time TS of the terminal. That is, the time consumed by the terminal from the currently available power to the full power is less than the time when the terminal leaves the tag area (for example, the time when the user goes out with the terminal), so that the terminal is fully charged within the first charging time PT 1. When the first charging time PT1 is greater than the time difference T1, the time difference T1 is determined as the actual charging time TS of the terminal. That is, the time consumed by the terminal from the currently available power to the full power is longer than the time the terminal leaves the tag area, so it is required to be fully charged as much as possible within the time T1.

In summary, when PT1< T1, TS ═ PT 1; when PT1> T1, TS ═ T1.

In step 207, the wireless charging apparatus sets a power distribution priority level according to the actual charging time of each terminal.

In the embodiment of the present disclosure, when the power distribution priority level is set according to the actual charging time of each terminal, the terminal with the minimum actual charging time is set as the highest priority, and the terminal with the maximum actual charging time is set as the lowest priority. That is, the smaller the actual charging time is, the higher the power distribution priority level corresponding to the terminal is, the charging power is preferentially distributed to the terminal in the subsequent process, and the more the charging power is distributed to the terminal; the larger the actual charging time is, the lower the power distribution priority level corresponding to the terminal is, the later charging power is distributed to the terminal in the subsequent process, and the distributed charging power is smaller.

In step 208, the wireless charging device allocates charging power to each terminal based on the power allocation priority level and the current unallocated power of the wireless charging device.

In the embodiment of the present disclosure, after the actual charging time TS of each terminal is calculated, the actual charging times of the terminals may be sequentially labeled as TS1, TS2, ts3.. TSn, etc. according to the power allocation priority level. Wherein, the smaller the index value, the shorter the actual charging time, and the higher the power distribution priority level. The symbol S (scale) represents the charging power, and the charging powers to be allocated to the terminals with the time charging times TS1, TS2, and ts3.. TSn, respectively, may be sequentially labeled as S1, S2, S3.. Sn, and the like. The S1 value is the largest, and the Sn value is the smallest. That is, if the time that a certain terminal is away from the mark area is shorter, the charging power allocated to the terminal is higher; if a certain terminal is away from the mark area for a long time or the terminal does not leave the mark area, the lower the charging power allocated to the terminal. When charging power is distributed to each terminal, the following modes can be adopted:

firstly, the charging power of the terminal with the minimum actual charging time TS value is calculated preferentially.

Wherein Z refers to the wireless charging device's current unallocated power;

Σ TSn ═ TS1+ TS2+ TS3+. + TSn, n denotes the total number of terminals connected to the wireless charging device and not distributing charging power, i is a positive integer, 0< i ≦ n, TSi denotes the actual charging time connected to the wireless charging device and distributing charging power for the ith terminal, the actual charging time of the ith terminal is greater than the actual charging time of the i-1 st terminal and less than the actual charging time of the i +1 st terminal, and Si denotes the charging power distributed for the ith terminal. In the embodiment of the present disclosure, the charging power of the terminal with the minimum actual charging time may be preferentially calculated.

And step two, calculating the charging power of the terminal with the second smallest value and the third smallest value of the actual charging time TS in sequence.

Note that, at this time, TSi of the terminal that has calculated the charging power is eliminated. For example, it is assumed that the actual charging time TS1 of the terminal 1 is 20 minutes, the actual charging time TS2 of the terminal 2 is 30 minutes, and the actual charging time TS3 of the terminal 3 is 50 minutes. The TS value of terminal 1 is minimal. As can be seen from the above equation (2), the charging power S1 to be allocated to terminal 1 is 1- (20/20+30+50) × 1 is 80%. Since the wireless charging apparatus allocates the charging power to the first terminal, the unallocated power is 1. The charging power S2 ═ 1- (30/30+50) ] (1-S1) should be allocated to terminal 2 equal to 12.5%.

Where the remaining unallocated power of the wireless charging apparatus at this time is 1-S1-20%, the TS value 20 of the terminal 1 to which the charging power has been allocated is eliminated from Σ TSi.

After the charging power of each terminal is allocated according to the method shown in step 208, the analysis module in the wireless charging device sends the identity of each terminal and the corresponding charging power value S to the power allocation module in the wireless charging device. And then, the power distribution module charges each terminal according to the charging power value S of each terminal. In addition to determining the charging power allocated to each terminal according to the time when each terminal leaves the mark area historically, the actual charging time of each terminal may also be determined according to the weather conditions (for example, the user goes out when the weather is clear, and the user does not go out when the weather is cloudy or rainy) during current charging and the schedule information recorded by the user in each terminal, and then the charging power is allocated to each terminal according to the obtained actual charging time, which is not specifically limited in the embodiment of the present disclosure.

According to the method provided by the embodiment of the disclosure, when connection establishment with a plurality of terminals is detected, the current available electric quantity of each terminal is obtained; acquiring the time of each terminal leaving a mark area counted in advance, wherein the wireless charging equipment is positioned in the mark area; distributing actual charging time for each terminal based on the current available electric quantity of each terminal and the time of each terminal leaving the marking area; setting a power distribution priority level according to the actual charging time of each terminal; the charging power is distributed for each terminal based on the power distribution priority level and the current unallocated power of the wireless charging equipment, and the charging power is distributed for each terminal based on the time when each terminal leaves the mark area, so that the equipment which is urgently carried by a user to go out can be preferentially charged, the charging efficiency is effectively improved, the intelligence is better, and the user experience is better.
