[0001] This application claims the benefit of U.S. Provisional Application Ser. No. 61/161,358, filed Mar. 18, 2009, which is hereby incorporated by reference.
Technical Field
[0002] This disclosure relates to electric vehicles, and, more particularly, to a method, system, and apparatus for distributing electricity to electric vehicles, monitoring the distribution thereof, and/or controlling the distribution thereof.
Background
[0003] Pure electric vehicles and plug-in hybrid electric vehicles are rapidly entering the vehicle transportation marketplace. Discontented with energy prices in general and the damage caused to the environment by conventional combustion chamber vehicle technology, societies around the world are seeking alternatives. These and other factors are transforming the transportation landscape and encouraging the adoption of new and cleaner technologies.
[0004] Price efficiencies are playing a role in the adoption of electric vehicles. While battery technologies remain the single largest cost in the production of an electric vehicle, such cost is considerably offset by the price of energy for operating an electric vehicle, which is significantly lower than that of running a conventional gasoline vehicle. For example, in today's prices, to drive an electric vehicle 30 miles costs around $0.60 compared with around $2.00-$3.00 for a gasoline vehicle. Eventually, the cost of batteries will fall because of improved manufacturing efficiencies; as a result, the electric vehicle adoption rate will inevitably increase.
[0005] However, one of the challenges with electric vehicle transportation is the ability for electric vehicle users to conveniently recharge their vehicles. Although electric vehicles are four to five times more efficient than gasoline cars, they suffer from a lack of infrastructure that effectively limits how far they can travel. This can discourage the wider public from adopting electric vehicle technologies.
[0006] Early adopters of electric vehicles are generally conscious of the environment. They are aware of the severe damage to the planet caused by some types of energy sources. They might seek to reduce their own carbon footprint by closely monitoring energy consumption, particularly as a result of their own transportation needs. An awareness of the various sources of energy and related energy consumption statistics are areas of interest for such owners. For example, electric vehicle owners might be concerned that electricity being used to charge their own electric vehicle originates from a coal-fired power plant rather than a windmill farm. Access to knowledge about the sources and amounts of electricity would be valuable and worthwhile to such vehicle owners, and could lead to improved driving habits.
[0007] Some current owners of conventional gasoline powered vehicles might be inclined to change to a more environment-friendly vehicle if the change were incentivized in some manner. Perceptions exist that electric vehicles are inferior, particularly in terms of performance. Access to charging stations is limited. Still others believe that only those who can afford the newer and cleaner technologies can make the change to electric. Such barriers could be removed with a system accessible to all members of society, especially one that encourages efficient and affordable vehicle-recharging access to every-day drivers.
[0008] Unfortunately, no such infrastructure is available to vehicle owners today. Greater numbers of charging locations for vehicles to recharge quickly and affordably could mean lower costs by reducing battery payloads, and would broaden the range of travel. Nevertheless, there are challenges related to providing secure, accessible, and affordable, yet profitable, distribution of electricity to electric vehicles. Challenges also remain for monitoring and controlling the distribution of electricity to electric vehicles.
[0009] Accordingly, a need remains for a method, system, and apparatus for distributing electricity to electric vehicles, monitoring the distribution thereof, and/or controlling the distribution thereof. Embodiments of the invention address these and other limitations in the prior art.

[0016] The foregoing and other features of the invention will become more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.
Detailed Description
[0017] FIGS. 1 and 1A illustrate a system 100 including various components and information related to an electric-vehicle charging infrastructure, such as components to monitor and control the distribution of electricity to electric vehicles according to one example embodiment of the invention. The system 100 is generally directed toward a “pay” model where operators or owners of electric vehicles are inclined to pay money, or otherwise compensate station owners and/or electricity providers, for charging their vehicles. The system 100 also prevents unauthorized individuals or vehicles from misappropriating electricity.
[0018] More particularly, one or more plug outlet devices, such as 80 and 85, are associated with a station 55. While two plug outlet devices 80 and 85 are shown, it should be understood that one or any number of plug outlet devices fall within the scope of this disclosure. The station 55 can include various forms and be located at any place such as a traditional gasoline station, a specialized electric vehicle charging station, a parking garage, a home, an apartment complex, a workplace, or a vehicle fleet charging location, among other possibilities. The station 55 can include the plug outlet devices 80 and 85, the switch component 72, and the coordinator element 40, or otherwise be associated therewith. The term “station” should be construed broadly to include any provider of electric vehicle charging services, whether for profit or not-for-profit, public or private, large or small. Moreover, while often referred to herein as “electric vehicles,” such vehicles can include plug-in hybrid vehicles, pure electric vehicles, or any one of a variety of vehicles that operate or move using at least some electricity.
[0019] The plug outlet devices 80 and 85 can include various features such as a two or three-prong plug outlet, and electrical conductors 74 connecting the plug outlet devices to the switch component 70. While the figures show example embodiments of the plug outlet devices 80 and 85, these can include various different forms, shapes, and various additional components, whether or not specifically illustrated in the figures. The switch component 70 is “normally-closed” and operatively associated with the plug outlet device 80 and 85. The term “normally-closed” means that the switch component 70 normally connects a source of electricity 60 to the plug outlet devices 80 and 85 so that owners or operators of electric vehicles, generally referred to herein simply as “operators,” can cause their vehicles to receive a charge from the source of electricity 60.
[0020] The switch component 70 can include one or more switches. Preferably, each plug outlet device 80 and 85 has an associated switch in the switch component 70. Alternatively, the plug outlet devices 80 and 85 can each include a switch rather than the separate switch component 70. The source of electricity 60 is coupled to the switch component 70 over conductor 62. Preferably, the source of electricity 60 includes an environment friendly source of electricity, such as wind or solar power, although any and all sources of electricity fall within the scope of this disclosure.
[0021] Each of the plug outlet devices, such as 80 and 85, include information 10 (of FIG. 1A ) about the station 55. For example, the information 10 about the station 55 may be stored in a station identifier (ID) tag, such as tags 20 and 25. The station ID tag can include, for example, a radio frequency identifier (RFID) tag, an infrared emitter, an optical emitter, or a radio signal generator, among other suitable emitters or transmitters. Generally, the station ID tags 20 and 25 are configured to transmit the information 10 about the station 55 toward one or more electric vehicles, such as 90 and 95. The information 10 about the station 55 can include, for example, a station location ID 11, a plug outlet device ID 13, or energy sources information 12, among other possibilities.
[0022] The station ID tags can each include an autonomous tag, such as 20 and 25, that is configured to transmit the information 10 about the station 55 at predefined time intervals. Alternatively, the station ID tags can each include a presence-sensor, such as 20 and 25, to sense a presence of the vehicles 90 or 95 and transmit the information 10 about the station 55 toward the vehicles responsive to the sensed presence, thereby conserving power. For example, the presence-sensor may sense a presence of the vehicles using a conductive sensor, infrared (IR) sensor, or motion sensor, among other suitable sensors. Nevertheless, the station ID tags need not receive data or indicia from the vehicles 90 or 95.
[0023] Each of the vehicles 90 and 95 can include a power cord such as 92 and 93 coupled to the vehicle, and a plug adapter such as 38 and 39 for plugging into the plug outlet devices 80 and 85, respectively. Although the terms “cord” and “power cord” are frequently used herein, such terms can include any type of conductor, and/or may include a protective element around the conductor. A fob, such as 30 and 31, may be attached to the respective power cords, or otherwise associated with a vehicle, and may receive the information 10 about the station 55 from at least one of the respective station ID tags 20 or 25. The station ID tags may be configured to unidirectionally transmit the information 10 about the station 55 to the fob. For example, the fob 30 may include receiver 34 and the fob 31 may include receiver 35. The receivers 34 and 35 may receive the information 10 about the station 55, such as the station location ID 11, from the station ID tags 20 or 25, and may store such station information in the corresponding fob.
[0024] Each fob 30 and 31 may be coupled to a corresponding sensors, such as 36 and 37, which can include current or voltage sensors, to sense an amount of electrical current or energy received from the corresponding plug outlet device 80 or 85. In addition, each fob 30 and 31 can store information 15 (of FIG. 1A ) about the corresponding vehicle 90 and 95. For example, the information 15 about the vehicle can include vehicle energy usage information 16, such as the amount of electrical current or energy received from the corresponding plug outlet device 80 or 85. In addition, the information 15 about the vehicle may include a cryptographic key pair 17 identifying the owner or operator of the vehicle, a vehicle identifier (ID) 18, or the time or date 19 of receiving the electrical charge, among other possibilities.
[0025] Transmitters, such as 32 and 33, included in the fobs 30 and 31, respectively, can transmit the information 15 about the vehicles 90 and 95, respectively, and the information 10 about the station 55 to a receiver 41 of a coordinator element 40. In other words, the coordinator element 40 receives the vehicle information 15 and the information 10 about the station 55 from the vehicles, in particular, from the fobs 30 and 31 that are attached to the vehicles. Preferably, the coordinator element 40 wirelessly receives such information. In one embodiment, the coordinator element 40 is a computer that is proximally located to the plug outlet devices 80 and 85, and also to the vehicles 90 and 95 when they are parked near the plug outlet devices 80 and 85. As a result, the wireless connection between the fobs 30 and 31 and the coordinator element 40 can use short-distance wireless connections, such as infrared, optical, or short-range radio technologies.
[0026] The coordinator element 40 may be operatively associated with the switch component 70. For example, the coordinator element 40 can cause the normally-closed switch component to open and disconnect the source of electricity 60 from at least one of the plug outlet devices 80 and 85 responsive to a presence or absence of wireless signal(s) 46. The wireless signal(s) 46 can include the information (e.g., 10, 15) transmitted from at least one of the fobs 30 and 31 to the coordinator element 40, which can detect the presence or absence of the wireless signal(s) 46 and verify the information contained therein. Specifically, the coordinator element 40 may receive the wireless signal(s) 46 from any of the transmitters 32 and 33 of the fobs 30 and 31.
[0027] In addition to verifying the presence of the wireless signal(s) 46, the coordinator element 40 can also verify the vehicle information 15 or the information 10 about the station 55. For example, the coordinator element 40 can transmit such information (e.g., 10, 15) to one or more remote computer servers 50 for verification. The remote computer server 50 is operatively coupled to the coordinator element 40 over a network, and may store such information when it is received. The network can include a local area network (LAN), a wide area network (WAN), the Internet, a wireless network, a satellite communication network, among other suitable networks. When the coordinator element 40 determines that the vehicle information 15 or information 10 about the station 55 is invalid, or otherwise fails to verify such information with the remote computer server 50, the coordinator element 40 can transmit a denial of service signal 44 to the switch component 70.
[0028] More specifically, the remote computer server 50 may determine that the information (e.g., 10, 15) or some portion of the information is invalid; for example, when the information does not correlate with a valid or sufficiently funded account associated with the vehicle, or if some portion of the information such as the cryptographic key pair is invalid, the information may fail verification. Upon failure of the verification, the coordinator element 40 sends the denial of service signal 44 to the switch component 70 and the normally-closed switch component 70 opens and disconnects the source of electricity 60 from at least one of the plug outlet devices 80 or 85, or otherwise disables the plug outlet device, responsive to the denial of service signal 44. The denial of service signal 44 can include the plug outlet device ID 13 so that the switch component 70 can determine which plug outlet device to disable.
[0029] The coordinator element 40 can also transmit the denial of service signal 44 in the absence of a fob (not shown). In other words, if a vehicle operator attempts to draw a charge or current from one of the plug outlet devices, and does not have a fob to proceed with authorized charging of the vehicle, the system can manage such a scenario as follows. A detector 72, which may be included in the switch component 70, can sense an electrical current draw from one of the plug outlet devices 80 or 85. In other words, when a vehicle is plugged into one of the plug outlet devices, current will begin to be drawn from the source of electricity 60, and the detector 72 can detect the same.
[0030] The switch component 70 generates a current draw detection signal 42, which is transmitted to the coordinator element 40. When the coordinator element 40 receives the current draw detection signal 42, it can check for a presence or absence of a wireless signal 46 from one of the vehicles. In the absence of the wireless signal 46, and responsive to the current draw detection signal 42, the coordinator element 40 can transmit a denial of service signal 44 to the switch component 70. Moreover, if the wireless signal 46 is present when the current draw detection signal 42 is received, the coordinator element 40 can verify the vehicle information 15 or information 10 about the station 55 responsive to the current draw detection signal 42. The denial of service signal 44 can cause the switch component 70 to disable a corresponding plug outlet device, as previously discussed. Therefore, unauthorized vehicle operators are prevented from charging their vehicles.
[0031] FIG. 2 illustrates another system 105 including various components related to an electric-vehicle charging infrastructure, such as components to monitor the distribution of electricity to electric vehicles according to another example embodiment of the invention. The system 105 is generally directed toward a “free” model, sometimes referred to as a “no charge” model, where operators or owners of electric vehicles are not inclined to pay money, and may even need to be incentivized to charge their vehicles using such an infrastructure. This is particularly useful for early adopters of electric vehicles. Moreover, the system 105 can spur the adoption of an electric vehicle charging infrastructure, such as the one disclosed herein, and provide useful monitoring of the distribution of electricity to vehicle operators and/or station owners. Notably, the “free” or “no charge” model can “overlay” any current charging infrastructures or stations, which can be “upgraded” to use various embodiments of the present invention. Although the system 105 is generally referred to as the “free” or “no charge” model, that is not to suggest that no revenue can be generated. For example, information about the various aspects of the distribution of electricity to electric vehicles itself has value.
[0032] Many of the components illustrated in FIG. 2 correspond to similar components of FIG. 1 , and for the sake of brevity, a detailed description of such components will not be repeated. While many of the components remain, such as the plug outlet devices 80 and 85, and the coordinator 40, etc., some components need not be included, such as the switch component 70. As a result, operators of vehicles 90 and 95 can access plug outlet devices 80 or 85 without any specific authorization or verification. Nevertheless, the operators may be incentivized, or otherwise have a desire, to use fobs such as 30 and 31 when receiving a charge for their vehicles.
[0033] For example, reports based on vehicle energy usage, station energy usage, energy sources information, or station location information, can be aggregated and displayed to either the vehicle operators or the station owners, as will be described in detail below. Such information can inform the vehicle operators and station owners about the overall aspects of their transportation-related energy usage, and can help alter behaviors in favor of improving the environment or energy conservation. Moreover, knowing one's “carbon footprint” and related information can be useful and informative to the vehicle operator or station owner, and having and sharing such information may further one's reputation.
[0034] In system 105, the source of electricity 60 is coupled to the plug outlet devices 80 and 85 over conductor 62. The vehicles such as 90 and 95 can plug into plug outlet devices 80 and 85 and immediately begin receiving a charge. The fobs 30 or 31 may operate in a manner similar to or the same as that described above by transmitting information such as vehicle information 15 and information 10 about the station 55 to the coordinator element 40. The coordinator element 40 can transmit such information to the remote computer server 50, which can aggregate and/or store such information for later display.
[0035] FIG. 2A illustrates an example configuration of components similar to those of FIG. 2 . The station 55 can be located close to a sidewalk 91 or curb 98. For example, in cities or in front of homes, vehicles can be parked next to a sidewalk or curb. Alternatively, vehicles can be parked in rows of spaces associated with a garage, an apartment complex, a special event center, a parking lot, or other suitable parking locations. Embodiments of the present invention can be implemented or associated with any such arrangement or complex.
[0036] In one example, the vehicle is parked next to the sidewalk 91 or curb 98. The curb 98 need not be located next to the sidewalk 91. Here, a cord 62 couples the source of electricity 60 to the plug adapter 64. The plug adapter 64 can include station ID tag 20, which includes capabilities similar to or the same as the station ID tag 20 previously described. The plug adapter 64, including the station ID tag 20, can be coupled to the plug adapter/fob 30, which is in turn coupled to the electric vehicle 90 via cord 92. The plug adapter/fob 30 can communicate with the plug adapter 64, the station ID tag 20, the coordinator element 40, or the remote computer server 50, as previously discussed in detail above.
[0037] The station 55 is illustrated as a physical building in FIG. 2A , including the coordinator element 40, the receiver 41, and the source of electricity 60. In other embodiments, the station 55 includes a general location with different components located proximally to the building but not necessarily attached to or in the building.
[0038] A protective cover 97 can be disposed over the cord 62 to protect pedestrians from tripping over or otherwise contacting the cord 62. The protective cover 97 can be made of a flexible durable material, such as rubber, that conforms to the shape of the cord 62. Alternatively, the protective cover 97 can be made of a rigid durable material, such as metal or plastic, or any other suitable material. The protective cover 97 can also draw attention to the station 55 or the cord 62 so that pedestrians or other individuals are aware of the presence of these components. Moreover, the protective cover 97 can include advertisements that tout the availability of electric vehicle charging services, sponsorship information, or other suitable advertisements. Preferably, the protective cover 97 is securely fixed to the sidewalk 91 or curb 98. While the cord 62 is shown extending over the sidewalk 91 and curb 98, it should be understood that the cord 62 can instead be completely or partially buried in the ground between the source 60 and the plug adapter 64. In addition, while a single cord 62 and plug adapter 64 are illustrated in FIG. 2A , it should be understand that any number of cords 62 can be coupled to the source 60 of the station 55, thereby providing electric vehicle charging services to any number of electric vehicles simultaneously. The capabilities and features of the components discussed above with reference to FIGS. 1 , 1A, and 2 can also apply to the example configuration of components illustrated in FIG. 2A .
[0039] FIG. 3 illustrates yet another system 107 including various components related to an electric-vehicle charging infrastructure, such as components to monitor the distribution of electricity to electric vehicles according to yet another example embodiment of the invention.
[0040] The system 107 is also generally directed toward a “free” or “no charge” model where operators or owners of electric vehicles are not inclined to pay money, and may even need to be incentivized to charge their vehicles. Again, this is particularly useful for early adopters of electric vehicles, or to spur the adoption of an electric vehicle charging infrastructure, such as the one disclosed herein. As previously suggested, although the systems 105 and 107 are generally referred to as the “free” or “no charge” model, revenue can still be generated by the station owners, energy providers, or other entities monitoring, or otherwise managing or displaying, information about the distribution of electricity.
[0041] Many of the components illustrated in FIG. 3 correspond to similar components of FIG. 1 , and for the sake of brevity, a detailed description of such components will not be repeated. While some of the components remain, such as the plug outlet devices 80 and 85, etc., most of the components mentioned in FIG. 1 need not be included, such as the switch component 70 and the coordinator element 40. As a result, operators of vehicles 90 and 95 can access plug outlet devices 80 or 85 without any specific authorization or verification. Nevertheless, the operators may be incentivized, or otherwise have a desire, to use fobs such as 30 and 31 when receiving a charge for their vehicles.
[0042] In system 107, the source of electricity 60 is coupled to the plug outlet devices 80 and 85 over conductor 62. The vehicles such as 90 and 95 can plug into plug outlet devices 80 and 85 and immediately begin receiving a charge. The fobs 30 or 31 can transmit information such as vehicle information 15 and information 10 about the station 55 directly to the remote computer server 50, thereby bypassing the coordinator element 40. The remote computer service can then aggregate and/or store such information for later display. In this embodiment, the fobs 30 and 31 can use long-range wireless connections to transmit wireless signal(s) 46, such as over a cellular network, Worldwide Interoperability for Microwave Access (WiMAX®) network, wireless local area network (WLAN), or WI-FI® network, among other suitable networks.
[0043] FIGS. 4-8 illustrate alternative configurations of some of the components of the systems of FIGS. 1-3 , according to some embodiments of the invention. Generally, having a close proximity of the fob, such as 30, to the station ID tag, such as 20, improves a communication link and reduces a chance for communication errors. The communication link between 30 and 20 can include a short-distance wireless technology as discussed above, or a conductive link.
[0044] FIG. 4 shows a combined plug adapter and fob 30. The plug adapter/fob 30 includes the transmitter 32 and receiver 34 as previously described, and can also include, for example, the sensor 36 of FIG. 1 . In this embodiment, the plug adapter/fob 30 is portable and can be attached to the plug adapter 38 or power cord 92, which are coupled to the vehicle 90. The plug adapter/fob 30 can communicate with the plug outlet device 80, the station ID tag 20, the coordinator element 40, or the remote computer server 50, as previously discussed in detail above. The plug outlet device 80 can be coupled directly to the source of electricity 60 via cord 62, or to the switch component 70 (of FIG. 1 ).
[0045] FIG. 5 shows a combined plug adapter and fob 30. Also illustrated is a combined plug adapter and station ID tag 20. The plug adapter/fob 30 includes the transmitter 32 and receiver 34, and other capabilities, as previously described. The plug adapter/fob 30 can also include, for example, the sensor 36 of FIG. 1 . The plug adapter 64 includes station ID tag 20, which includes capabilities similar to or the same as the station ID tag 20 previously described. In this embodiment, the plug adapter/fob 30 is portable and can be attached to a plug inlet 94 of the vehicle 90. The plug adapter 64 can be coupled directly to the source of electricity 60 via cord 62, or to one of the plug outlet devices (of FIG. 1 ), or to the switch component 70 (of FIG. 1 ). The plug adapter 64, including the station ID tag 20, can also be coupled to the plug adapter/fob 30. The plug adapter/fob 30 can communicate with the plug outlet device 80, the plug adapter 64, the station ID tag 20, the coordinator element 40, or the remote computer server 50, as previously discussed in detail above.
[0046] FIG. 6 shows vehicle 90 having the fob 30 located within the vehicle. Also illustrated is a combined plug adapter and station ID tag 20. The fob 30 includes the transmitter 32 and receiver 34, and other capabilities, as previously described. In addition, the fob 30 can be connected inline between the plug inlet 94 and battery 96, and can include, for example, the sensor 36 of FIG. 1 . The plug adapter 64 includes the station ID tag 20, which also includes capabilities similar to or the same as the station ID tag 20 previously described. In this embodiment, the plug adapter/fob 30 is generally fixed to or otherwise part of the vehicle. The plug adapter 64 can be coupled directly to the source of electricity 60 via cord 62, or to one of the plug outlet devices (of FIG. 1 ), or to the switch component 70 (of FIG. 1 ). The plug adapter 64 can be coupled to the plug inlet 94 of the vehicle 90. The plug adapter/fob 30 can communicate with the plug outlet device 80, the plug adapter 64, the station ID tag 20, the coordinator element 40, or the remote computer server 50, as previously discussed in detail above.
[0047] FIG. 7 shows a combined plug adapter and fob 30. The plug adapter/fob 30 includes the transmitter 32 and receiver 34 as previously described, and can also include, for example, the sensor 36 of FIG. 1 . In this embodiment, the plug adapter/fob 30 is portable and can be attached to the plug adapter 38 or power cord 92, which are coupled to the vehicle 90.
[0048] Conversely, the plug adapter 22, which includes the station ID tag 20, can be initially separate from the plug outlet device 80, and then substantially permanently secured to the plug outlet device 80. For example, a tamper-resistant screw 24 can securely attach the plug adapter 22 to the hole 26 of the plug outlet device 80. Other permanent attaching means can be used such as glue or welding, etc. This provides the ability for station owners to “upgrade” their plug outlet devices by attaching the plug adapter 22 to their plug outlet device.
[0049] The plug adapter/fob 30 can communicate with the plug outlet device 80, the plug adapter 22, the coordinator element 40, or the remote computer server 50, as previously discussed in detail above. The plug outlet device 80 can be coupled directly to the source of electricity 60 via cord 62, or to the switch component 70 (of FIG. 1 ).
[0050] FIG. 8 shows a combined plug adapter and fob 30. Also illustrated is the plug adapter 22, which includes the station ID tag 20, and can be initially separate from the plug adapter 28, and then substantially permanently secured to the plug adapter 28. For example, a tamper-resistant screw 24 can securely attach the plug adapter 22 to the hole 26 of the plug adapter 28. Other permanent attaching means can be used such as glue or welding, etc. This provides the ability for station owners to “upgrade” their plug outlet devices by attaching the plug adapter 22 to their plug adapter 28. The plug adapter 22 includes capabilities similar to or the same as the station ID tag 20 previously described.
[0051] The plug adapter/fob 30 includes the transmitter 32 and receiver 34, and other capabilities, as previously described. In this embodiment, the plug adapter/fob 30 is portable and can be attached to a plug inlet 94 of the vehicle 90. The plug adapter/fob 30 can also include, for example, the sensor 36 of FIG. 1 . The plug adapter 22 can be coupled to the source of electricity 60 via the plug adapter 28 and the cord 62, or to one of the plug outlet devices (of FIG. 1 ), or to the switch component 70 (of FIG. 1 ).

[0052] FIGS. 9-11 illustrate additional aspects of the systems illustrated in FIGS. 1-8 . FIG. 9 illustrates the computer server 50 of FIG. 1 , including additional connections to various computing devices. FIG. 10 illustrates various reports and displays of information, including different sections of a web site for receiving registration information from a vehicle operator and/or reports for displaying aggregated information to the vehicle operator. FIG. 11 illustrates various reports and displays of information, including different sections of a web site for receiving registration information from a station owner, and/or reports for displaying aggregated information to an owner or employee of a station.
[0053] The computer server 50 aggregate at least some of the information 15 about the vehicle, and/or the information 10 about the station 55. The computer server 50 can store such information, including the aggregated information, on a storage device (not shown) included in the computer server 50 or separate from the computer server 50. One or more reports can be generated based on the stored aggregated information, stored in the computer server 50, and/or provided to a vehicle operator or station owner.
[0054] For example, the computer server 50 can generate a vehicle energy usage report 220 (of FIG. 10 ) for the vehicle operator, and can indicate “Your Usage” to highlight that this usage is related to the vehicle operator's usage. The report 220 can include a graph showing the usage over time or for a particular date range; the graph can show the usage as Kilowatt/hour units, among other possibilities.
[0055] Similarly, the computer server 50 can generate a station energy usage report 320 (of FIG. 11 ) for the station owner, and can indicate “Vehicle Usage” to highlight the energy usage of a particular vehicle or patron. The report 320 for the station owner can be similar to the report 220 for a particular vehicle.
[0056] Additionally, the computer server 50 can generate a station energy usage report 215 (of FIG. 10 ) for the vehicle operator, which indicates energy usage that is related to a particular station at which the particular vehicle received charges. The report 215 can include a graph showing the usage over time or for a particular date range, and a particular station ID to identify the station. The graph can show the usage as Kilowatt/hour units for the particular station, among other possibilities.
[0057] Similarly, the computer server 50 can generate a station energy usage report 315 (of FIG. 10 ) for the station owner, which indicates energy usage that is related to a particular station at which all vehicles for that station have received charges. The report 315 can include a graph showing the usage over time or for a particular date range, and a particular station ID to identify the station. The graph can show the usage as Kilowatt/hour units for the particular station, among other possibilities.
[0058] Further, the computer server 50 can generate an energy sources information report, such as 240 or 340. The report 240 can include, for example, a pie chart showing percentages of energy usage, and their sources, for a particular vehicle. Other types of graphs or charts can be used. Conversely, the report 340 can include, for example, a pie chart showing percentages of energy usage, and their sources, for all vehicles that have received charges at a particular station.
[0059] Another is the station location identifier report 230 or 330. The 230 report can show different locations on a geographic map having indicators such as circles or dots. The circles or dots (among other possible shapes or indicators) show which stations were visited, or in other words, where a particular vehicle received a charge in relation to the location on the map. A vehicle operator can quickly assess his or her driving and/or charging habits. Moreover, a size of the dot or circle (or other indicator) can correspond to an amount of electricity used at that particular station. In addition, the reports can include a function to help the vehicle operator find stations that offer the charging capability. The report 230 can also include ratings of the reliability of the stations, which may be rated by other vehicle operators. The report 230 may also show the price of electricity at each station. Optionally, a zoom in/out adjuster allows the vehicle operator to zoom in on a particular geographic location, or zoom out to see a wider perspective. The report 330 is similar to the 230 report, and allows an owner of multiple stations to monitor energy usage or related location information for each of the stations. Alternatively, the report 330 allows the station owner to compare usage at their station to usage at other stations, view ratings of the reliability of other stations, and/or the price offered by other stations, among other possibilities.
[0060] Any of the reports mentioned above can be stored in the computer server 50 or displayed on a website, which can be accessed by computing devices, such as personal digital assistants (PDA) 140 or 150, computer 130, or mobile phones 110 or 120. For example, the computer server 50 can transmit the aggregated information or reports to one or more computing devices. The aggregated information or reports can be transmitted to the computing devices using Silent Messaging Service (SMS) text messages, automated voice calls, Internet web sites, and/or email, among other possibilities. As mentioned above, vehicle owners or operators can access the reports as well as station owners or employees.
[0061] Sign-up pages 200 and 300 provide a means for registering operators of vehicles or station owners. For example, sign-up page 200 can be used to register operators of vehicles who desire to have the ability to charge their vehicles, or who would otherwise want to monitor or track the energy usage of their vehicles. The sign-up page 200 can request home address information, vehicle information, and/or billing information, among other possibilities. Upon registration, a fob such as 30 or 31 can be shipped to the vehicle operators. Preferably, the fob that is shipped is associated with a particular vehicle, which is owned or operated by the person registering using page 200.
[0062] Similarly, sign-up page 300 can be used to register station owners. For example, if a station owner wants to adopt the “pay” model, the components related to such model, such as the station ID tags, switch component 70, and/or coordinator element 40, can be shipped to the station owner. If a station owner wants to adopt the “free” or “no charge” model, fewer components, such as the station ID tags, can be shipped. The station ID tags can be preconfigured with information 10 about the station 55, or alternatively, configured at the station 55.
[0063] Profile pages 210 and 310 can list account information for a particular vehicle operator or station owner. For example page 210 can show a vehicle operator account number, total energy usage information for a particular vehicle, stations visited for charges, and an account balance, among other suitable account-specific information. In a similar fashion, page 310 can show a station owner account number, total energy usage information, stations owned and monitored, and an account balance, which can include surcharges, for electricity distributed, among other suitable account-specific information.
[0064] Such reports allow vehicle operators and/or station owners to evaluate their “carbon footprint” based on, for example, whether the sources of energy are environment friendly, the amount of energy used, particular routes or amounts of travel, and so forth.
[0065] From the foregoing it will be appreciated that, although specific embodiments of the invention have been described herein for purposes of illustration, various modifications may be made without deviating from the spirit and scope of the invention.
[0066] For example, although the embodiments described above include a “free” model and a “pay” model, the “free” model can be upgraded to the “pay” model by adding one or more components, such as the switch component 70 and/or the coordinator element 40. The alternative configuration of components illustrated in FIGS. 4-8 can be used in any combination, for example, with components or elements illustrated in FIGS. 1-3 and/or FIGS. 9-11 .
[0067] The “free” or “no charge” model need not require electrical work for installation, and can pinpoint the origin, type, and/or cost of the energy being used. Component and communication costs are reduced. Such infrastructure can be installed easily using, for example, adhesives, screws, or ties. The “free” model can be upgraded to the “pay” model by adding certain components, as explained above. The “free” model may include a “standalone” mode that allows vehicle operators to track their energy usage, even where there is no station ID tag or coordinator element. The operator can have access to real-time energy usage monitoring.
[0068] The “pay” model includes additional components, but that can be easily installed. The switch component can be placed at a breaker box, or instead, coupled to or otherwise associated with the plug outlet device. A particular station can be disabled remotely, for example, using a web site. Such model is flexible and provides control to both infrastructure operators and station owners. Station owners that provide charging to particular fleets of vehicles, for example, can deny charging capabilities to non-fleet vehicles. The “pay” model can be purposely converted to a “free” model by removing or bypassing certain components, such as the switch component or coordinator element.
