DETAILED DESCRIPTION
[0032] The technology of the present application will now be described more fully below with reference to the accompanying figures, which form a part hereof and show, by way of illustration, specific exemplary embodiments. These embodiments are disclosed in sufficient detail to enable those skilled in the art to practice the technology of the present application. However, embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. The following detailed description is, therefore, not to be taken in a limiting sense.
[0033] The technology of the present application is described with specific reference to photovoltaic cells (a/k/a solar panels), commercial refrigeration systems, grid power as a load, electric vehicles as a load, local power networks as a load, combinations thereof, and the like. However, the technology described herein may be used with applications other than those specifically described herein. For example, the technology of the present application may be applicable to wind generation systems, server farms, home air conditioning systems, morgue refrigeration systems, or the like. Moreover, the technology of the present application will be described with relation to exemplary embodiments. The word “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments. Additionally, unless specifically identified otherwise, all embodiments described herein should be considered exemplary.
[0034] With reference now to
[0035] The panels 114 gather light and output electricity. The panels 114 may be coupled to a power conditioner as describe in U.S. Pat. No. 9,647,300, incorporated herein as if set out in full, which may condition the power for coupling to a power grid, residential power network, or a local load, such as through retractable power cords 212 shown in
[0036] As can be seen in
[0037] As seen in
[0038] The articulating arm 210 may include an anchor portion 222, an upper arm portion 224, an intermediate arm portion 226, and a lower arm portion 228. The anchor portion 222 in this exemplary embodiment is a vertical sleeve 230 that terminates in a rotatable coupling 232. The upper arm portion 226 is coupled to the rotatable coupling 232 such that the upper arm portion 226 is able to rotate about an axis extending vertically through the vertical sleeve 230. In some embodiments, the rotatable coupling also allows the upper arm portion 226 to pivot and rotate, similar to ball and socket joint. The upper arm portion 226 is coupled to the intermediate arm portion 226 at a first joint 234. The first joint 234 is envisioned to be a hinge joint to allow the intermediate arm portion 226 to pivot with respect to the upper arm portion 224 (or, conversely, the upper arm portion 224 pivots with respect to the intermediate arm portion 226), but the first joint 234 may be a ball and socket joint or the like to allow additional degrees of freedom. The lower arm portion 228 is coupled to the intermediate arm portion 226 at a second joint 236. The second joint 236 is envisioned to be a hinge joint to allow the intermediate arm portion 226 to pivot with respect to the lower arm portion 228 (or, conversely, the lower arm portion 228 pivots with respect to the intermediate arm portion 226), but the second joint 236 may be a ball and socket joint or the like to allow additional degrees of freedom. Each of the upper arm portion 224, intermediate arm portion 226, and lower arm portion 228 may be a single tubular member or a plurality of telescoping members. The upper arm portion 224, intermediate arm portion 226, and lower arm portion 228 may be hollow to allow the power cord 212 to traverse internal to the arms. While shown with an intermediate arm 226, in some embodiments, the upper arm portion 224 and the lower arm portion 228 are coupled together without an intermediate arm 226. Also, in some embodiments, there are multiple intermediate arms 226 between the upper arm portion 224 and the lower arm portion 228.
[0039] The first joint 234, second joint 236, the rotating coupling 232, and/or all, a combination of, or none of them may be biased, such as, for example, a spring hinge, to lift the articulating arm 210 towards the roof 112 when the not in use. To facilitate using the articulating arm 210, a pull member 238 may be coupled to the distal end of the lower arm portion 228. Pulling the pull member 238 allows a user to lower the articulating arm 210.
[0040] The power connector 208 in certain embodiments may comprise the retractable power cord 212 extending directly from the energy storage cartridge 204 and terminating in a plug assembly 216. In this case, the pull member 238 would be coupled to the retractable power cord 212 proximal the plug assembly 216 such that the retractable cord 212 could be extended from the energy storage cartridge 204.
[0041] The distal end of the power cord 212 extends from the opening 240 on the distal end of the lower arm portion 228. The distal end 218 of the power cord 212 terminates in the plug assembly 216. The power cord 212 is a flexible cord such that a user, or driver, can align the plug 220 with the socket of the electric vehicle. In some embodiments, the power cord 212 may extend from the energy storage cartridge 204 to the plug assembly 216. In other embodiments, the power cord 212 may only extend only from the lower arm portion 228, intermediate arm portion 226, or upper arm portion 224 rather than the energy storage cartridge 204. In such a case, a conductor extends from the end of the power cord to the energy storage cartridge to couple the plug assembly 216 to the batteries B. In some embodiments, the plug assembly may include a plurality of plugs 220 (or a plurality of sockets, or a combination of a plurality of plugs and a plurality of sockets) to accommodate different connections to different batteries that are to be charge by the electric vehicle charging stations 120. While consumer and commercial vehicles are described in the present application, other batteries could and likely would be charged using the solar canopy 100.
[0042] In use, for example, a driver (or user) would drive an electric vehicle EV, see
[0043] In some embodiments, the rotating coupling 232, first joint 234, and second joint 236 may be controlled by a motor, or multiple motors, such as one or more servo motors or the like. The motors would be controlled by a joystick or a computer 300, which computer may be a server, edge server, microprocessor, or the like, as shown in
[0044] The computer 300 includes a bus 302 that is operable to transfer data between hardware components. The components include a processor 304, such as a CPU or microprocessor, a network interface 306, an input/output (I/O) system 308, a clock system 310. The input/output system 308 may receive input from location sensors on the plug assembly 216 and the output single may drive the motors such that the rotating coupling 232, first joint 234, and second joint 236 move the plug assembly 216 to a determined location for the electric vehicle EV corresponding socket. To facilitate some of the communication described herein the computer 300 may include as part of the I/O system 308 one or more radio frequency transceivers (or separate receivers and transmitters).
[0045] In some embodiments, the plug assembly 216 may include an optical unit that provides input to the I/O system 308. The processor 304 would process the optical input and determine how to move the articulating arm 210 such that the plug 220 aligns with the electric vehicle EV socket. In certain embodiments, the electric vehicle charging station 120 may include a reader to scan (or otherwise acquire) the VIN number of the electric vehicle EV. The processor 304 would identify the make and model of the electric vehicle EV from the VIN. The processor 304 would have a known location of the electric vehicle EV socket, and the processor 304 would drive the motors such that the plug 220 aligns with the known location of the socket. In yet other embodiments, the processor 304 may connect wirelessly with a smart device of the driver of the electric vehicle EV and the driver would use a control application (such as one containing directional arrows or the like) to provide signals to the processor 304 to drive the articulating arm 210. These, as well as other, means for driving the articulating arm 210 to automatically cause the plug 220 to electrically couple with the electric vehicle EV socket are possible.
[0046] The I/O system 308 also receives input from sensors electrically coupled to the power cord or upstream from one or more of the cartridges associated with the solar canopy 100. The sensors may sense the rate of energy (such as amps or kilowatts per unit of time), total accumulated energy transfer (such as for example a percentage of battery charge or kilowatt/hours), and the like. The I/O system 308 may also receive information from a sensor in the plug assembly 216 (or located elsewhere) that determines the charge or energy capacity of the electric vehicle EV battery, which may be a percentage such that 0% is fully drained and 100% is fully charged). The processor 304 would receive the inputs and output through the I/O system 308 to a display information/data for the driver of the electric vehicle. Typically the information/data to be displayed would be charge or price data. As shown in
[0047] With reference to
[0048] The solar canopy 100 is shown receiving and/or sending packages 501 by drones 502.
[0049] After the package drop off, the logistics processors would cause the elevator platform 508 to descend the elevator shaft to the level of the locker 507. The processors controlling the logistics would next cause conveyors, such as conveyor belts, in the arrival locker assembly 506 to move the package 501 to the locker 507 and deposit the package 501 in the locker 507. The delivery instructions include, among other things, identification information for the recipient of the package 501. The recipient information may include a cellular telephone number or user identification that allows the processors controlling the logistics to transmit a message to the recipient, which message may be transmitted via a phone call, a text message, an email, a short message service, or other transmission. The message to the recipient would include, among other things, the solar canopy 100 location and locker 507 identification. The message may also include a lock code, which may be a combination or a radio frequency lock code to a mobile smart device that the recipient can use to unlock locker 507. The recipient may the person to which the package is supposed to be delivered or a delivery service 512, such as, FedEx® or UPS® to name but two (2) possible services. Also, while a person 504, or robot 504, is shown transferring the package from the locker 507 to the delivery service 512, in certain embodiments, the delivery service may include an autonomous vehicle that has a means for retrieving the package from the locker 507.
[0050] Similarly, but in reverse, to send a package, a user would communicate to the logistic processors, for example, the computer 300, a pickup request and delivery instructions. The computer 300 would transmit an assigned locker 507 into which the user would place the package 501. The computer 300 would coordinate with a delivery service 512 or drone 502 to retrieve the package. If a delivery service 512, the delivery service 512 would pick up the package as defined above. If a drone, the assigned drone 502 would land on an elevator platform 508 associated with a departure elevator 511, which is shown on the opposite side of the canopy 100 in
[0051] With reference back to
[0052] Drones 502 have limited flying range and time due to energy use.
[0053] The logistic processors, such as the computer 300 described above, controlling the drones 502 and delivery services 512 require the processing and transmission of a large amount of data and may use a large amount of throughput, especially when logistic processors provide flight paths for the drones 502 or the delivery services 512 are autonomous. The data processing requirements and throughput may strain available communication bandwidth, especially in more remote locations. Thus, the solar canopy 100 solves the throughput and data processing issues by providing processor and servers, such as the logistic processor cartridge 615 shown in
[0054]
[0055] The solar canopy 100 also includes power conditioners, which condition the energy from the solar panels or batteries for the various services, such as power to computers, electric vehicles, drones, lights, cameras (security or otherwise), and the like. The power conditioners include among other things a solar inverter cartridge 650 and a transformer cartridge 651.
[0056] The In certain embodiments, the solar canopy 100 may include a retractable cell tower 652. The retractable cell tower would have a retractable antenna 653 and a retractable remote radio head 654. The tower stanchion 656 would typically be hollow to allow for a conductor to a base station (which may be mounted in a cartridge on the solar canopy or in a kiosk or other housing proximate the solar canopy 100).
[0057]
[0058] The solar canopy 100 may also include a plurality of grid edge server cartridges 659. The grid edge server cartridges 659 can be used for a variety of functions. For example, the grid edge server cartridges 659 may be used for mining crypto currencies. The solar canopy 100 in some embodiments is ideal to house crypto mining servers as the servers can be cycled on and off as required to provided power as required to other services, such as, for example, the logistics processors described above or the grid when additional grid power is necessary.
[0059] As is explained further in U.S. Pat. No. 10,587,015, which is incorporated herein by reference as if set out in full, the solar canopy may include a thermal storage cartridge 660. The thermal storage cartridge 660 may include a compartment for the pumps and controllers and a compartment for the refrigerant and thermal energy exchangers or the like.
[0060]
[0061]
[0062]
[0063] With reference to
[0064] As described above, the solar canopy 100 may include a retractable cell tower 652. However, in certain aspects, the retractable cell tower 652 may be a satellite antenna in certain embodiments or other type of radio frequency antenna. Also, the solar canopy 100 may have multiple retractable antenna to allow for combinations thereof. The retractable cell tower 652 would be electrically coupled to a power source such as, for example, the energy storage cartridge 204 and be powered electrically from either the solar panels 114, a high capacity battery (or batteries), or the power network such as a power grid or residential power network to allow for radio communication. In certain embodiments, a backup electrical generator may provide emergency power to the solar canopy 100. This is especially useful in emergency conditions, such as, for example, relief efforts for hurricanes, humanitarian aid for disaster zone, war zones, and the like, when a power grid or residential power network in unavailable.
[0065] The batteries referred to in the application are high capacity batteries. In certain embodiments, the high capacity batteries may be specially designed. In some cases, the high capacity batteries may be batteries from an electrical vehicle, such as is available from Tesla, Nisson, or the like. One of ordinary skill in the art would recognize on reading the disclosure that such a high capacity battery is configured to store at a minimum approximately 75-100 kWh (kilo watt hours) of power. Generally, the term high capacity battery as used herein stores at least 100 kWh to 150 kWh, but higher and lower capacity batteries are contemplated by the technology of the present application. Generally, the minimum capacity for the technology of the present application would be approximately 10 kWh. The high capacity battery may be of many types including lithium ion, lead acid, and the like to name but two (2) types of batteries. As can be appreciated, high capacity batteries in the magnitude of 10 or more kWh produce a significant amount of heat that must be dissipated by a heat dissipation system, as will be further explained below.
[0066] As more fully described in the applications and patents incorporated by reference above, the solar canopy 100 may include one or more heat dissipation systems. Fans and vents may be used singularly or in conjunction with means for dissipating heat depending on the kWh of the batteries. For example, it is possible that simple air cooling will not be sufficient for the high capacity batteries described herein. Simple air cooling generally refers to convection to ambient air. The heat dissipation system may include heat exchangers, a pump etc., to facilitate fluid flow for cooling of the battery or cartridges. The means for dissipating heat may also include forced air systems, which would include fans and compressors as well as pumps, etc.
[0067] As shown in
[0068] The technology of the present application, however, is scalable to a very high voltage, amperage arrangement. As mentioned above, each high capacity battery may be capable of storing up to approximately 150 kWh using conventional technology. The solar power canopy 100, however, may store several such batteries.
[0069] Importantly, as can be appreciated, each of the cartridges, as described herein, may contain both the high capacity storage batteries as well as the electronics to connect the same to the loads and means for dissipating heat.
[0070] Other uses for the technology include, among other things having the external unit be an electric vehicle charger to allow for high capacity charging of electric vehicle batteries. This may be particularly useful in remote locations where access to national or State power grid is not available. The solar panels and high capacity batteries ensure the electric vehicle charger station would always have sufficient stored energy or available energy to charge an electric vehicle battery. Yet another use is for computing power, such as, for example, cryptocurrency mining computational power. Servers mining cryptocurrency, or solving the equations, use a tremendous amount of energy, but the servers may be intermittently turned off as needed. Thus, powering servers using the solar canopy renewable energy and/or stored energy allows for powering the servers to solve equations when power is available. For those solar canopies with connections to a national or State power grid, the servers could also be shut off when the national or State power grids are at peak or exceeded power demands such that additional power can be provide to the grid. The solar canopies also are uniquely suited to solve cryptocurrency equations for those currencies that require “GREEN” energy sources.
[0071] While suppling alternative electrical energy may reduce the on-peak demand of the associated unit to which the solar canopy is associated, whether the associated unit is a local building (commercial or residence) or grid, the high capacity storage batteries only store a portion of the overall energy need for the associated unit over the on-peak demand. That is to say, typically the high capacity storage batteries only provide reduced energy demands for a few hours of operation of most commercial buildings, which requires the commercial building to use grid power for the time the high capacity storage batteries cannot provide the full load of energy. In most cases, the high demands of the commercial building result from refrigerant systems, such as food storage, server room temperature control, or HVAC systems.
[0072] The technology of the present application provides that some of the plurality of cartridges include thermal storage cartridges 660,
[0073] In certain embodiments of the technology, the cartridge 660 houses a refrigerant energy storage tank 1400 filled with a working fluid, which may be, for example, water, salt water, certain waxes, or other material that experiences a phase change at the working temperature and pressure. The refrigerant energy storage tank 1400 would include insulation 1404 to retain the energy within the tank as much as possible. The refrigerant energy storage tank 1400 includes one or more fluid conduits 1406, which may be coils. The fluid conduits would be in fluid communication with a local refrigerant system 1408 of an HVAC or refrigerant system, which is not shown but generally understood in the art, through a conduit or pipe. The local refrigerant system 1408 would have a refrigerant fluid 1410 that would flow into and out of the refrigerant energy storage tank 1400 through the fluid conduits 1406.
[0074] During off-peak demand times, the refrigerant energy storage tank 1400 would evaporate the refrigerant fluid 1410, which would take heat from the working fluid causing the working fluid to become a liquid or a solid (depending on the phase change temperature). In the case of water, or salt-water, the working fluid would change to ice during off-peak demand times. This process stores refrigerant energy in the refrigerant energy storage tank 1400 (the energy storage is generally referred to as the latent heat of phase change). Generally, the compressor of the HVAC system or refrigerant system operates to cause the working fluid 1410 to change from water to ice in this exemplary working fluid example. The compressor of the HVAC or refrigerant system, however, is operating during off-peak demand when energy is more economical.
[0075] As explained above, the refrigerant fluid 1410 is used in refrigerant energy storage tank 1400 to add or remove energy from the working fluid. Certain embodiments of the technology, however, may require additional separation between the refrigerant energy storage tank 1400 and the refrigerant fluid 1410. To facilitate the additional separation, a vapor compression cycle including compressors, pumps, evaporator, pipes, and valves may be incorporated into the cartridges 660.
[0076] During on-peak demand times, the stored refrigerant energy is released back to the HVAC system by reversing the process and releasing heat from the refrigerant fluid 1410 to the working fluid causing the working fluid to become a gas or a liquid (again depending on the phase change temperature). In the case of ice, the working fluid would phase change from ice to water, or salt-water. While releasing the stored refrigerant energy back to the HVAC system or refrigerant system, the compressor of the HVAC system or refrigerant system will ideally be idle or operate minimally during time of on-peak demand times.
[0077] Although the technology has been described in language that is specific to certain structures and materials, it is to be understood that the invention defined in the appended claims is not necessarily limited to the specific structures and materials described. Rather, the specific aspects are described as forms of implementing the claimed invention. Because many embodiments of the invention can be practiced without departing from the spirit and scope of the invention, the invention resides in the claims hereinafter appended. Unless otherwise indicated, all numbers or expressions, such as those expressing dimensions, physical characteristics, etc. used in the specification (other than the claims) are understood as modified in all instances by the term “approximately.” At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the claims, each numerical parameter recited in the specification or claims which is modified by the term “approximately” should at least be construed in light of the number of recited significant digits and by applying ordinary rounding techniques. Moreover, all ranges disclosed herein are to be understood to encompass and provide support for claims that recite any and all subranges or any and all individual values subsumed therein. For example, a stated range of 1 to 10 should be considered to include and provide support for claims that recite any and all subranges or individual values that are between and/or inclusive of the minimum value of 1 and the maximum value of 10; that is, all subranges beginning with a minimum value of 1 or more and ending with a maximum value of 10 or less (e.g., 5.5 to 10, 2.34 to 3.56, and so forth) or any values from 1 to 10 (e.g., 3, 5.8, 9.9994, and so forth).
