## Background
TECHNICAL FIELD
This disclosure generally relates to charging systems, and more particularly to systems and methods for smart wireless charging.
BACKGROUND
Mobile devices have become an integral part of the computing landscape. As mobile devices become more capable they have shifted to perform tasks that have traditionally been performed by non-mobile computers. In one example, mobile devices may have the ability to stream media, display videos, or otherwise process large amounts of data over the course of a day. The increasing use of mobile devices by consumers, along with the high dynamic range of power consumption across mobile devices, may cause certain components of the mobile device to wear down, such as the battery or power source. In some instances, certain applications of mobile devices may consume large portions of the battery powering the mobile device, resulting in a frequent need to charge the mobile device. Consumers may also have multiple mobile devices needing to be charged, but may only have a limited amount of time to do so. Charging systems, however, may not optimally charge mobile devices connected to the charging system. Accordingly, systems and methods for smart wireless charging may be desired.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE DISCLOSURE
Embodiments of the disclosure are described more fully hereinafter with reference to the accompanying drawings, in which example embodiments of the disclosure are shown. This disclosure may, however, be embodied in many different forms and should not be construed as limited to the example embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Like numbers refer to like, but not necessarily the same or identical, elements throughout.
Example embodiments of the disclosure may provide systems and methods for power distribution allocation to mobile devices, such as, but not limited to, mobile communication devices, laptops, smartphones, tablets, internet of things devices, such as applicances, wearables (including headsets, watches, health monitors, etc.) or other mobile devices. Example embodiments may include one or more mobile devices wirelessly connected to a wireless charging system. The charging system may be configured to wirelessly charge, or provide power defined as energy per unit time, to connected mobile devices. For example, the charging system may implement or otherwise include magnetic resonance technology to wirelessly charge, or distribute power, to connected mobile devices. However, the charging system may have a limited charging capacity. In instances where there is congestion at the charging system, such as a high demand for charging by one or more devices connected to the charging system, the charging system may not be optimized for efficient wireless charging for the connected devices. Situations may arise where certain mobile devices may be incompletely or partially charged, or charging of certain devices may be delayed. The charging systems of the present disclosure provide optimized smart or wireless charging, resulting in improved user experience at the charging system as users may designate priority for charging desired devices. Other forms of wireless charging may be utilized, examples of which are described herein and include, but are not limited to, capacitive charging, inductive charging, and other wireless charging methods.
The charging system may determine a charge program to charge connected mobile devices based at least in part on a charge request received from the mobile device and one or more charging system policies of the charging system. The charging system policies may include or be associated with one or more charging rules, such as rules associated with power allocation, priority ranking, or mobile device authentication, which may be stored and/or retrieved from a charging system user, such as an Information Technology manager or charging system owner. The charging system may determine specific charge programs for each connected mobile device based at least in part on one or more of the charge requests received from each connected mobile device, where charge requests may include mobile device information, and/or requests for power allotment. Mobile device information received by the charging system may include, for example, runtime context such as current applications running on the mobile device (including in some embodiments central processing unit (CPU) utilization information), current battery charge levels, available time for charging, mobile device identifiers, user identifiers, or other mobile device identification and/or specification information. The charging system may wirelessly charge connected mobile devices based at least in part on the determined charge program for each connected mobile device. The charging system may periodically refresh or modify charge programs based on responses to updated mobile device information from connected mobile devices.
According to certain example embodiments of the disclosure, the charging system may optimize use of the available charging capacity of the charging system and efficiently charge connected mobile devices by prioritizing charging of certain mobile devices, such that prioritized mobile devices receive, or are allocated, a disproportionate amount of power from the charging system. For example, mobile devices with limited charge capacity may need less energy or power than mobile devices with greater charge capacity. However, in some cases mobile devices with limited charge capacity may receive a maximum acceptable charge that is still less than energy being provided to the mobile device with greater charge capacity, leading to a disproportionate amount of power. Charging of mobile devices may be more efficient and may charge in reduced lengths of time. For example, a charging system user may define a charging system policy for mobile devices connected to the charging system. The charging system policy may include, but is not limited to, rules related to charging specific mobile device types or mobile devices with a certain runtime context (e.g., user defined prioritized applications), for example mobile devices running a particular mobile application or type/class of mobile application. In one example, the charging system policy may indicate that a smartphone connected to the charging system is to be prioritized and fully charged at a maximum receivable power at a faster charge rate or before any other type of mobile device. The charging system may therefore determine a charge program for smartphones where the smartphone receives a maximum power level until charge completion, and is prioritized with respect to other connected mobile devices that are not smartphones. In other examples, the charging system policies may indicate that mobile devices actively running a critical application(s) or other runtime context, such as a music streaming application as defined by the charging system user, are to be prioritized and charged to at least 80% before other mobile devices not running the critical application(s) are charged at a maximum charge rate. In some embodiments, in instances where the charging system is congested, power may be reallocated from lesser priority mobile devices to the higher priority mobile devices when a higher priority mobile device is added. When a lower priority device is added, power may not be reallocated unless, for example, a user overrides the charging system. The charging system policies may also indicate that mobile devices associated with specific users, such as loyalty card holders or company employees, are to be prioritized over certain other mobile devices. In some embodiments, the charging system policies may be used by the charging system to set an order of importance, a power allocation, or a priority rank for mobile devices with respect to other connected mobile devices. In some embodiments, the charging system may determine a power allocation for connected mobile devices without specifically determining a priority rank or otherwise creating an order or a charge priority.
In an illustrative embodiment, a charging system may have a total charging capacity of 15 watts. The charging system may not be charging any mobile devices, leaving an available charging capacity of 15 watts. A first mobile device user may position a smartphone at the charging system, where the smartphone is associated with the mobile device user who in this illustrative embodiment may be a member of a loyalty program managed by the charging system user. The charging system may establish a wireless connection with the smartphone through any wireless protocol, as discussed below, for example through a beacon or a handshake process, where the charging system emits a beacon and the smartphone responds to the beacon to establish a wireless connection. Once connected, the smartphone may transmit a charge request to the charging system. The charge request may include a minimum power allotment request, for example 5 watts, and a maximum power allotment request, for example 10 watts, where the minimum and maximum power allotment requests are associated with the amount of power the smartphone is capable of receiving during charging. The charge request may also include mobile device information, which may include a user identifier associated with the mobile device user, for example, the loyalty rewards member, and a mobile device identifier associated with the type of mobile device, which in this case would identify the mobile device as a smartphone. The mobile device information may also include runtime context information associated with mobile applications running on the smartphone, which may include for example streaming video, and a current battery charge level, which may be 80%.
The charging system may receive the charge request and the mobile device information from the smartphone. The charging system may identify one or more charging system policies based at least in part on the charge request. For example, based at least in part on the mobile device information received from the smartphone, the charging system may identify charging system policies associated with smartphone devices, loyalty members, active mobile applications, and battery charge levels. In one example, the charging system policy may include a charging rule associated with smartphone devices indicating that smartphones are to be charged to at least 95% at maximum charge at a maximum charge rate before other mobile devices receive maximum charge at a maximum charge rate for the respective mobile devices. The charging system policy may also include a charging rule associated with loyalty members indicating that mobile devices associated with loyalty members, regardless of type, are to be fully charged at maximum power before mobile devices belonging to non-loyalty members.
The charging system may determine a charge program for the smartphone based at least in part on the charge request and the identified charging system policy or policies. The charge program may also set a priority rank or power allocation, for example, prioritizing smartphones over other connected devices, based at least in part on the charging system policies. The charging system may wirelessly charge the smartphone based at least in part on the determined charge program. For example, the charging system may determine that since the smartphone is entitled to the highest priority charging, the smartphone should therefore receive a maximum charge until the smartphone is charged to at least 95%, at which point the charge program can be modified. In some embodiments, where no additional mobile devices are connected to the charging system, the charging system may determine a charge program for the smartphone to include 10 watts, the maximum power receivable by the smartphone, until the smartphone is charged to 95%. In other embodiments, the wireless charging system may apply maximum charge rates to prioritized mobile devices along with, or independent of, maximum charge.
Further to this illustration, a second mobile device user may position a tablet computer at the charging system. The second mobile device user may not be a member of the loyalty rewards program of the charging system user. The charging system may establish a second wireless connection with the tablet computer, and the tablet computer may transmit a charge request to the charging system indicating a minimum power allotment of 5 watts and a maximum power allotment of 20 watts. The charge request may include mobile device information indicating the mobile device is a tablet computer, has a current battery charge level of 50%, and a list of running applications. The charging system may receive the charge request from the tablet computer and may identify one or more charging system policies applicable to the tablet computer. For example, the charging system may identify a charging system policy including a charging rule for mobile devices belonging to users that are not loyalty rewards members, another charging system policy associated with the mobile device type, or tablet computer in this case, and another charging system policy associated with mobile devices with runtime context indicating certain mobile applications are running. The charging system may request and receive updated mobile device information from the smartphone. Updated mobile information may include updated mobile information regarding the current charge level, the current received charge rate, and the like, as described herein. For example, the updated mobile device information may indicate the smartphone battery now has a charge level of 90%. The charging system may consider the updated mobile device information in determining the charging program for the mobile device and/or other connected mobile devices, as discussed below.
The charging system may determine a charge program for the tablet computer, based at least in part on the charge request and the identified charging system policies for the tablet computer. The charging system may also consider the updated mobile device information from the smartphone. The charge program for the tablet computer may include a priority rank for the tablet computer relative to the computer, which may be based on the charging policies for both the smartphone and the tablet computer. The charging system may determine a power allocation for the tablet computer. In this illustration, the charging policies may indicate that mobile device type policies are prioritized with respect to loyalty member policies, which are prioritized with respect to battery charge level policies. The charging system may determine that the smartphone is prioritized over the tablet computer because of the mobile device type, where the charging system policy indicates smartphones are prioritized over other mobile device types. The charging system may therefore continue providing the smartphone maximum power until the smartphone reaches 95%, or as determined by the charging policy. The charging system may then determine a charge program for the tablet computer, where the tablet computer has a lower priority level with respect to the smartphone. For example, the charge program for the tablet computer may indicate the tablet computer receives an available charge of 5 watts, calculated by subtracting the power allotted to the smartphone from the charging capacity of the charging system, until the smartphone reaches 95% charge, at which point the charge program for the tablet computer may be updated to provide maximum power to the tablet computer and the charge program for the smartphone may be updated to provide residual power to the smartphone. The charging system may wirelessly charge the tablet computer and the smartphone simultaneously.
In other instances, the charging system policies may indicate mobile devices associated with loyalty rewards members may be prioritized, or devices above a certain battery charge level threshold may not be prioritized, such as battery charge levels of 80% or greater. Other charging system policies may include charging rules based on mobile device authentication, for example, only authorized users may be allowed to charge mobile devices, minimum charge level across all or certain devices, for example, mobile devices with less than 50% charge are prioritized, available time for charging, for example if a mobile device may only be connected for a period of 10 minutes before the mobile device will be removed, or other charging rules as described herein. Additional systems and methods for smart wireless charging are described herein.
In example embodiments, the mobile devices discussed herein may have one or more antennas and/or transceivers, such as antennas and/or transceivers (e.g., radios) for wirelessly communicating with, for example, one another and/or the charging system. Sample forms of wireless communication may include WiFi, WiFi DirectTM, BLUETOOTHTM, BLUETOOTH LETM, Near Field Communication, and other suitable forms of wireless communication. In example embodiments, the mobile devices may be configured to wirelessly receive energy from the charging system. For example, the mobile devices may include resonators for engaging in a resonant magnetic induction energy transfer with the charging system.
It will be appreciated that in example embodiments, the systems and methods described herein may provide for and result in increased functionality for mobile devices, and/or optimal use of charging capacity for charging systems by utilizing charging policies to charge connected mobile devices.

The antennas 128, 212, 312 may be configured to receive and/or transmit signals in accordance with established standards and protocols, such as Institute of Electrical and Electronics Engineers (IEEE) 802.11 family of standards, including via 2.4 GHz channels (e.g. 802.11b, 802.11g, 802.11n), 5 GHz channels (e.g. 802.11n, 802.11ac), or 60 GHZ channels (e.g. 802.11ad). In alternative example embodiments, the antennas 128, 212, 312 may be configured to receive and/or transmit non-Wi-Fi protocol signals, such as BLUETOOTHTM, BLUETOOTHTM LE, Near Field Communication, dedicated short-range communication (DSRC), or other packetized radio communications.
Each mobile device 200, 300, as well as power transmission unit 102, may include an energy storage device, such as battery 140, 208, 308. Each battery 140, 208, 308 may be configured to provide energy or otherwise power each respective mobile device 200, 300. The batteries 140, 208, 308 may be any suitable type of battery including, but not limited to, wet cells, dry cells, lead-acid, lithium, lithium hydride, lithium ion, or the like, at any suitable voltage and/or output current. In certain embodiments, the batteries 140, 208, 308 may be rechargeable and may be recharged by one or more other power sources, such as the power transmission unit 102. Each battery 140, 208, 308 may be configured to receive and store energy.
The power transmission unit 102 and each mobile device 200, 300 may include a respective resonator 132, 220, 320. Each resonator 132, 220, 320 may be any suitable resonator configured to provide, distribute, transmit, or receive energy. For example, the resonator 132 of the power transmission unit 102 may be configured to transmit, emit, or otherwise transfer energy wirelessly, and the resonators 220, 320 of the mobile devices 200, 300 may be configured to receive the energy transmitted by the resonator 132 of the power transmission unit 102.

In some embodiments, the power supply 136 may be an intermediary between the power transmission unit 102 and the external power supply 138. The power amplifier 134 may amplify energy from the power supply 136 to ensure the resonator 132 has sufficient energy to wirelessly transmit or distribute energy. For example, the power amplifier 134 may provide current in order to generate flux, thereby inducing voltage at the resonator 132.
Referring now to FIGS. 2 and 3, an example method 410 and an example data flow 430 for wireless charging according to one embodiment of the disclosure are illustrated and will be discussed in conjunction with each other. Referring first to FIG. 2, method 410 illustrates one example method for wireless charging, in accordance with one embodiment of the disclosure, that may be performed by a charging system having features disclosed herein, for example charging system 100. Referring now to FIG. 3, data flow 430 includes the first mobile device 200 in wireless communication via the first wireless connection 106 with the charging system 100 (shown in FIG. 1). Data flow 430 also includes the second mobile device 300 in wireless communication via the second wireless connection 108 with the charging system 100. FIG. 3 illustrates data flowing between the components over time, denoted on the vertical axis.
Still referring to both FIGS. 2 and 3, at block 412 of FIG. 2, the charging system 100 may establish the first wireless connection 106 between the charging system 100 and the first mobile device 200. The first wireless connection 106 may be established by any of a number of methods. For example, turning to FIG. 3, one embodiment of block 412 is illustrated by the communications and/or operations included in exchange 432. Exchange 432 may include a communication from the charging system 100, for example a beacon, to determine if any mobile devices within range wish to connect to the charging system 100. In one example, the beacon may be emitted or transmitted by the power transmission unit 102 of the charging system 100 periodically or at predetermined time intervals using any of the above-described hardware and/or the communications module 124. Still referring to exchange 432, the first mobile device 200 may receive the beacon, using any of the above-described hardware and/or the communication module 216 of the first mobile device 200. In response, the first mobile device 200 may transmit a response or confirmation to the charging system 100 during exchange 432 using communication module 216, thereby establishing the first wireless connection 106 with the charging system 100. Other methods of establishing wireless connections between the charging system 100 and mobile devices may be implemented. For example, a handshake or authentication process may be implemented. Further, any device, including the power transmission unit 102 or any of the mobile devices 200, 300 may initiate the respective wireless connections, and additional or fewer communications and/or operations may be performed in order to establish the first wireless connection 106.
At block 414 of FIG. 2, the charging system 100 may receive a first charge request from the first mobile device 200. Referring to FIG. 3, at communication 434 the first mobile device 200 may transmit the first charge request to the charging system 100 using communication module 216. The first charge request may include power allotment information, such as a minimum receivable charge or power allotment and a maximum receivable charge or power allotment, corresponding to minimum and maximum power the first mobile device 200 may receive. Power allotments of the first mobile device 200 may be based on hardware configuration or may be determined by software, such as by operating system 218 of the first mobile device 200. The first charge request may include a desired power allotment corresponding to a power allotment the first mobile device 200 wishes to receive at the time the first charge request is transmitted. The desired power allotment may be based on the charge cycle of the first mobile device 200, for example based on if the first mobile device 200 is at a constant-current position or a constant-voltage position in a constant-current/constant-voltage charge cycle.
The first charge request may include mobile device information. Mobile device information may include, but is not limited to, any one of a mobile device identifier, a user identifier, a current charge level, an available charging time, a runtime context (e.g., applications running on the mobile device), a maximum receivable charge, or a minimum receivable charge. For example, mobile device information may indicate that a user has only 10 minutes available for charging. Other information may be automatically pulled from the first mobile device 200, such as calendar information. Using calendar information, the charging system 100 may determine that the user has a meeting in the room the charging system 100 is located in for a period of one hour. The charging system 100 may consider the calendar information in determining the charge program for the device. For example, if the user will only be in the room for an hour, the charging system 100 may attempt to fully charge the device within that time period. Examples of user identifiers may identify mobile devices belonging to employees or management. Using user identifiers may allow the charging system 100 to provide charge only to, or to prioritize charge, for employees over guests or for managers over other employees. Runtime context may include applications currently running on the mobile device. A charging system user may designate certain applications as “critical” and may set a charging system policy prioritizing charging for devices running applications designated as critical. For example, proprietary software, or email, or streaming video may be designated critical applications. Mobile device information may be determined by the charge request module 214 of the first mobile device 200. The charge request module 214 may communicate or interface with other electronic interfaces and/or software or hardware elements of the first mobile device 200 to request or receive mobile device information. The charge request module 214 may communicate with the communication module 216 to transmit the first charge request to the charging system 100. The first charge request may be transmitted or communicated to the charging system 100 in any suitable method of data transmission, and may be communicated in aggregate or in multiple communications.
While the charging system 100 receives the first charge request from the first mobile device 200, the charging system 100 may receive additional charge requests from the first mobile device 200, although not illustrated. For example, the first charge request may indicate the first mobile device 200 requests a desired power allotment of 10 watts because the battery charge level is low, but when the battery charge level reaches 80%, the first mobile device 200 may transmit another charge request indicating a desired power allotment of 5 watts. Although illustrated as occurring at different points along the vertical time axis, any portion of any of the operations or steps described above may occur at least partially concurrently with any portion of any other operation or step described above.
The charging system 100 may receive the first charge request from the first mobile device 200, and at block 416 of method 410, the charging system 100 may identify one or more charging system policies based at least in part on the first charge request. The one or more charging system policies may be associated with one or more charging rules applicable to the first mobile device 200. The charging system 100 may use the charging policy module 118 to identify the charging policy or policies. The charging system policy may be provided by a charging system user, either locally at the charging system 100 or remotely. For example, a charging system user may input charging policies and/or charging rules at the charging policy configurator 400, which may be pushed or automatically transmitted to the charging system 100. The one or more charging policies may include priority rank information, power allocation information, charging rules, mobile device parameter information, and other related information.
At block 418 of method 410 in FIG. 2, the charging system 100 may determine a first charge program for the first mobile device 200, based at least in part on the first charge request, and the identified charging system policy or policies. The first charge program may include a priority rank and/or power allocation of the first mobile device with respect to other mobile devices connected to the charging system 100. The charging system 100 may use the charge program module 120 to determine the first charge program. The priority rank and/or power allocation may be determined at the charging policy module 118 in one example, or at the charge program module 120 in another example. The priority rank and/or power allocation may be determined by a scoring process, where certain parameters, such as device type or device owner are allocated certain points, and devices with the highest score are prioritized over other devices.
Priority may also be determined based on a length of time a mobile device has been connected to the charging system 100. In one example, if a mobile device indicates it has an available charging time of 10 minutes, after the 10 minutes have passed the mobile device may be assigned lowest priority and charging may stop or be throttled, in order to prevent abuse of time-sensitive charging policies. The first charge program may include charging information specific to the first mobile device 200. For example, the first charge program may include a power allotment for charging, a designated charging time, the priority rank and/or power allocation of the first mobile device 200 with respect to other connected mobile devices, a designated battery charge level (e.g., charge to completion or certain percentage), or other charging information.
In some embodiments, the charging system 100 may consider the available charging capacity of the charging system 100 in determining the first charge program. The available charging capacity may be a total charging capacity or output of the charging system 100 less any charge allocated to connected mobile devices. For example, the charging system 100 may subtract power being drawn from the charging system from the total charging capacity of the charging system 100. In one example, the charging system 100 may have a total charging capacity of 15 watts, and a connected mobile device may be drawing 10 watts from the charging system 100, leaving an available charging capacity of 5 watts. In another embodiment, the charging system 100 may determine a physical position of the first mobile device 200 with respect to the charging system 100, where determining the first charge program of the first mobile device 200 may be based at least in part on the physical position of the first mobile device 200. For example, the charging system 100 may determine the physical position of the first mobile device 200 with respect to the power transmission unit 102. Certain areas of power transmission unit 102 may be associated with certain priority ranks or power allocation amounts. In one instance, high priority charge area 130 of the power transmission unit 102 may indicate that mobile devices positioned at the high priority charge area 130 are to be prioritized with respect to other mobile devices connected to the charging system 100.
At block 420, the charging system 100 may wirelessly charge the first mobile device 200 based at least in part on the first charge program determined at block 418. For example, the charge program module 120 may communicate with the charge distribution module 122 of the power transmission unit 102 to coordinate charging of the first mobile device 200. The charge distribution module 122 may instruct the charging components of the power transmission unit 102 to provide energy to the first mobile device 200. The charging components may include the resonator 132, the power amplifier 134, and the power supply 136 of the power transmission unit 102. In FIG. 3, operation 436 illustrates the charging system 100 charging the first mobile device 200 by providing power to the first mobile device. The first mobile device 200 may receive charge or power from the power transmission unit 102, for example through resonator 220, and may accordingly charge the battery 208 of the first mobile device 200. Although illustrated as occurring at different points along the vertical time axis, any portion of any of the operations or steps described above may occur at least partially concurrently with any portion of any other operation or step described above.
Referring now to FIG. 3, the charging system 100 may establish the second wireless connection 108 with the second mobile device 300. As discussed above with respect to the first wireless connection 106, the second wireless connection 108 may include the communications and/or operations included in exchange 438. Exchange 438 may include a communication from the charging system 100, for example a beacon. The second mobile device 300 may receive the beacon, using any of the above-described hardware and/or the communication module 316 of the second mobile device 300. In response, the second mobile device 300 may transmit a response or confirmation to the charging system 100 during exchange 438 using communication module 316, thereby establishing the second wireless connection 108 with the charging system 100.
At communication 440, the second mobile device 300 may transmit a second charge request to the charging system 100 using communication module 316. The second charge request may include second mobile device information, as discussed above with respect to the first charge request. The charge request module 314 may communicate or interface with other electronic interfaces and/or software or hardware elements of the second mobile device 300 to request or receive mobile device information. The charge request module 314 may communicate with the communication module 316 to transmit the second charge request to the charging system 100. The second charge request may be transmitted or communicated to the charging system 100 in any suitable method of data transmission, and may be communicated in aggregate or in multiple communications.
The charging system 100 may receive the second charge request from the second mobile device 300, and may identify one or more charging system policies based at least in part on the second charge request. The charging system 100 may use the charging policy module 118 to identify the one or more charging policies. In some embodiments, the charging system 100 may poll connected mobile devices for new charge requests, where the new charge requests comprise updated mobile device information. Polling may occur periodically or may be triggered by events, such as upon charge completion notification received from a connected mobile device. For example, the charging system 100 may transmit a request for a third charge request from the first mobile device 200, where the third charge request comprises updated first mobile device information. The charging system 100 may determine a current battery charge level of the first mobile device 200 via the updated first mobile device information included in the third charge request. The charging system 100 may also determine an available charging capacity of the charging system 100, as described above.
Based at least in part on the second charge request and the identified charging system policy or policies, the charging system 100 may determine a second charge program for the second mobile device 300, where the second charge program comprises a priority rank and/or power allocation of the second mobile device 300 with respect to the first mobile device 200 and any other mobile devices connected to the charging system 100. In some embodiments, the second charge program may be determined based at least in part on the third charge request and/or the available charging capacity of the charging system 100. Other embodiments may determine the second charge program based at least in part on any combination of these elements, and may include additional elements. The charging system 100 may use the charge program module 120 to determine the second charge program. The second charge program may include elements similar to the first charge program discussed above. For example, the second charge program may indicate the second mobile device 300 has a higher priority rank and/or power allocation than the first mobile device 200, and will therefore receive the desired power allotment until charge completion. In instances where the second mobile device 300 is determined to receive an amount of power that exceeds the available charging capacity of the charging system 100, the first charge program may be modified to reduce the power allocated to the first mobile device 200. The charging system 100 may redirect the divested power to the second mobile device 300, as it is prioritized. For example, the charge distribution module 122 may determine power is to be reduced to specific mobile devices with lower priority and may instruct the charging system 100 to reduce power to those mobile devices and to increase power to the prioritized mobile device or devices.
Upon determining the second charge program, the charging system 100 may wirelessly charge the second mobile device 300 based at least in part on the first charge program determined at operation 450. The charge program module 120 may communicate with the charge distribution module 122 of the power transmission unit 102 to coordinate charging of the second mobile device 300. The charge distribution module 122 may instruct the charging components of the power transmission unit 102 to provide energy to the second mobile device 300. The charging components may include the resonator 132, the power amplifier 134, and the power supply 136 of the power transmission unit 102. The second mobile device 300 may receive charge or power from the power transmission unit 102, for example through resonator 320, and may accordingly charge the battery 308 of the second mobile device 300. Although illustrated as occurring at different points along the vertical time axis, any portion of any of the operations or steps described above may occur at least partially concurrently with any portion of any other operation or step described above.
The charging system 100 may continue charging the first mobile device 200 as well. In some embodiments, for example where the second mobile device 300 is prioritized with respect to the first mobile device 200, the charging system 100 may determine an updated first charge program for the first mobile device 200. The charging system 100 may charge the first mobile device 200 based at least in part on the updated first charge program at operation 452. In other embodiments, the first charge program may remain unchanged, and the charging system 100 may continue charging the first mobile device 200 at operation 452 in accordance with the first charge program.
Referring still to FIG. 3, at communication 454 the first mobile device 200 may transmit a fourth charge request to the charging system 100, where the fourth charge request may indicate a charge completion or 100% charge level of the battery 208 of the first mobile device 200. The charging system 100 may receive the fourth charge request and may update the first charge program or determine a new charge program for the first mobile device 200 where the updated charge program no longer charges or otherwise provides power to the first mobile device 200 until it drops below a predetermined charge threshold, for example 95% of capacity. The charging system 100 may further update or determine a new second charge program for the second mobile device 300 based at least in part on the fourth charge request, for example at 458. In some embodiments, the charging system 100 may transmit a request for updated information to the second mobile device 300 at communication 456. For example, if the first mobile device 200 was prioritized with respect to the second mobile device 300, and the second mobile device 300 was receiving less than a maximum charge, upon charge completion of the first mobile device 200, the second charge program may be updated to allocate the maximum charge to the second mobile device 300. The charging system 100 may then charge, at 458, the second mobile device 300 at the maximum charge acceptable to the second mobile device.
It should be noted, that the method 410 may be modified in various ways in accordance with certain embodiments of the disclosure. For example, one or more operations of method 410 may be eliminated or executed out of order in other embodiments of the disclosure. Additionally, other operations may be added to method 410 in accordance with other embodiments of the disclosure.
The systems and methods described herein may result in increased functionality or optimal power distribution allocation of charging systems by maximizing use of available capacity of the charging system. In some embodiments, the charging system may allocate power or energy to a mobile device based at least in part on a minimum energy charge requested by the mobile device, and may reallocate power or energy to the mobile device based at least in part on requests made by the device.
