DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

[0018] Various examples of the present invention described herein are generally directed to systems and methods for, among other things, utilizing steam power to charge electric vehicles. It will be understood that the provided examples are for purposes of clarity and understanding, and are not meant to limit or restrict the claimed subject matter or relevant portions of this invention in any manner.

[0019] According to an aspect of the present invention, Steam Sources may be utilized to produce electrical power for charging electric vehicles. Steam Sources, include, but are not limited to: 1) steam distribution networks that are utilized in many locations, especially urban locations such as the Con Ed steam distribution network in New York City, which provide a clean energy power source to businesses, including industrial plants and manufacturing facilities, as well as hospitals, schools and universities, residences and other venues; 2) steam generators that are located at large venues such as industrial plants, manufacturing facilities, hospitals, universities, and others that are not accessible to a steam distribution network; 3) municipal electric power plants which primarily produce electricity, but also produce steam as waste; and 4) municipal steam generating plants which produce steam only. The Steam Source may also be subsequently utilized for a variety of applications. Such applications include heating, air conditioning, and generating electrical power.

[0020] A variety of methods may be implemented to utilize the energy associated with the steam. For example, steam turbines at the one or more locations may receive the pressurized steam from the Steam Source, and convert the steam energy to electrical energy. In embodiments, steam turbines may be specifically designed to receive the pressurized steam and directly generate power for electric car charging stations. Integrating steam power with electrical applications may help reduce the need for non-renewable energy sources, devices, and systems that require electrical power, as well as provide a cost-efficient and effective alternative to traditional methods.

[0021] FIG. 1 illustrates an example of a steam powered system 100 for charging electric vehicles, according to embodiments of the present invention. Steam 110 may be received from one or more steam-generating plants or steam sources 105, which may be at a same or different location as the steam-powered charging system, and part of a steam power network. One such example of a steam power network is New York City's Con Edison steam distribution system, which delivers pressurized steam through an underground pipeline system to businesses, residences, and locations throughout the city. In an aspect of the invention, pressurized steam 110 from the steam networks may be directed through one or more valves 115 to a steam turbine 120, which may be present or installed in or near a building, residence, outdoor location, or other location connected to the steam network. The valves 115 may be pressure regulating valves, and/or may also be pressure reduction or regulating stations, for example, and may control the flow of the steam 110. The valves may be managed by a control unit 134 associated with the generator 130 and turbine 120, e.g., a power management unit, as described herein, and may be controlled by physical means, e.g., manually opening or closing the valves. The valves may be present within a building's internal steam system network, and may assist in regulating the amount and direction of the steam 110 throughout the network and to the various delivery locations. For example, one or more volumetric flow meters may communicate a current velocity, pressure, and/or temperature of the steam flow to a computer, e.g., control unit 134, which may, in turn, regulate one or more physical aspects of the steam network to produce a steam flow with the ideal pressure and other properties prior to delivery to the turbine.

[0022] The steam turbine 120 may receive the pressurized steam 110 and utilize the flow to generate electrical energy at a generator 130. The operation and control (e.g., user interface) of the generator 130 and turbine 120 may be directed by a control unit 134 associated with the generator 130. In embodiments, the steam turbine 120 may be an extraction turbine or non-condensing steam turbine. In other embodiments, the turbine includes a number of rotors and stators to efficiently rotate a shaft connected to a generator 130. The generator 130 utilizes the turbine shaft's rotation within a magnetic field to generate an electrical current directly proportional to its rotation. In embodiments, the steam turbine 120 may be directly connected to the source of the pressurized steam 105, for example through pipelines and valves connected from the external and/or internal steam network to the turbine. The control unit 134 associated with the generator 130 may, for example, provide a control system screen which provides information regarding the input steam. This information may include steam inlet pressure, steam outlet pressure, steam inlet temperature, steam outlet temperature, steam valve position, and steam flow. The control unit 134 may also provide information on the electricity output, such as kilowatts generated (kWe), generator voltage, and generator current.

[0023] In other embodiments, the steam turbine 120 may utilize excess steam after the pressurized steam has passed through one or more turbines and/or electricity extraction methods. The steam turbine 120 may also use pressurized steam directly from the steam network and/or waste/excess steam. For example, as illustrated in FIG. 1, excess steam from the turbine may be redirected through one or more pressure regulating valves (PRV) 125 and recycled back through the valve 115 and the turbine 120 to generate electricity from the steam power.

[0024] After interaction with the steam turbine 120, the steam may be condensed into water, and/or subsequently utilized in one or more additional applications 135, including heating, humidification, and additional energy extraction techniques.

[0025] It will be appreciated that any of a plurality of steam turbine designs known in the art may be utilized in accordance with embodiments of the present invention. The functionality of steam turbine 120, generator 130, and control unit 134, as well as some of the related valve components, may be implemented by way of a Microsteam Power System provided by Carrier Corporation. It will also be understood that while embodiments are described as utilizing steam turbines to extract electrical energy, the present invention is not limited only to those technologies. Any of a plurality of systems and methods, which may include and/or utilize gas, oil, coal, water, electricity, combustion methods, etc., to produce electrical energy from steam, may also be used in accordance with one or more embodiments.

[0026] As discussed above, the generator 130 produces electricity from pressurized steam energy transferred to a rotating shaft within the turbine 120. In various embodiments, the generator 130 generates alternating current (AC), which may be subsequently converted to direct current (DC). In embodiments, either type of current may be utilized to charge a battery, fuel cell, capacitor, or other electrochemical cell storing electrical energy for subsequent consumption.

[0027] In one example, the generated electrical energy may be delivered directly to a battery for an electric vehicle. In other embodiments, the electrical energy may be utilized with high voltage chargers, such as Level 2 Charging Station 160a, Level 3 Charging Station 160b, Wireless Charging Station 160c, or Advanced Level 3 Charging Station 160d, to quickly and efficiently charge an electric vehicle. Level 2 chargers (160a), which operate on 240V AC power, can provide power at a rate of 19 kW (based on an 80 amp limited power source), fully charging a 100 kW battery in approximately five hours. Level 3 chargers (160b) deliver DC power directly to the electric vehicle at a voltage of 480V and higher current levels, which may charge an electric vehicle's battery up to 80% of its full capacity in under one hour. Wireless charging station 160c uses high power electromagnetic waves to deliver energy to an electric vehicle without requiring a direct connection between the electric vehicle and the charging station 160c. Advanced Level 3 Charging, also known as Ultra Fast charging can deliver 350 kW or more, and may fully charge an electric vehicle's battery in as little as 10-15 minutes. In all of these embodiments, one or more power managers, such as a control unit 140 may be present to manage the power flow from the generator prior to delivery to the electric vehicle.

[0028] In other examples, one or more storage units 132 may be in electrical connectivity with the generator 130 in order to store generated electricity until such energy is requested from the charging stations 160a, 160b, 160c or 160d to charge an electric vehicle 170 or other application. The storage units may continuously store generated energy until such energy is requested by one or more applications. During periods of low demand, the generated electricity would be stored in the storage units 132 and/or 133. In this manner, it may be ensured that energy is available for consumption, especially during peak delivery times, when high volumes of energy are requested or when the energy demand exceeds the rate at which electricity may be generated.

[0029] As discussed above, the charging system control unit 140 may manage and regulate the operation of the generator 130 to thereby control the flow of energy to the charging stations 160a, 160b, 160c or 160d, as well as to one or more storage units 132 and applications. The charging system control unit 140 may also have one or more associated storage units 133 in order to store generated electricity until such energy is requested from the charging stations 160a, 160b or 160c to charge an electric vehicle 170 or other application.

[0030] In various embodiments, the steam-generated electrical energy may be used in conjunction with various existing electric vehicle charging stations, providing an additional or exclusive source of energy for charging stations. In exemplary embodiments, the generated electricity will enable high voltage charging stations to efficiently receive green energy for high-speed charging. For example, the disclosed systems and methods may provide power to Tesla Supercharger stations, which are capable of supplying at least 480 V and electrical power up to approximately 90-135 kW. Embodiments may be modified, as necessary, to charge various types and sizes of batteries and storage units. For example, charging stations may be configured to receive electricity for charging a 480 V electrical vehicle battery pack, as well as electric vehicles with 40-100 kWh capacities.

[0031] It will also be appreciated that the electric vehicle charging stations are not limited to automobiles. In embodiments, the present invention may be utilized to charge electric bicycles, motorcycles, and/or any of a plurality of electric vehicles. The charging stations 160a, 160b or 160c and their respective power levels and delivery methods may be varied, for example, depending on the type of battery, battery capacity, and/or type of electric vehicle.

[0032] Embodiments may also include one or more charging system control units 140 to regulate various aspects of the electrical energy storage and delivery. The charging system control unit(s) 140 may utilize wired or wireless communication 145 to provide remote monitoring for one or more aspects of the system as described herein. For example, the charging system control unit 140 in conjunction with control unit 134 of the generator 130 may receive and transmit information to one or more of the valves 115, 125, turbine 120, generator 130, storage unit 132, storage unit 133, and any of the charging stations 160a, 160b, 160c to analyze aspects of the system, and manage power consumption and distribution. In this way, charging system control unit 140 may receive information regarding the status of turbine 120, generator 130, storage units 132, 133, and charging stations 160a, 160b, 160c, 160d, and similarly provide control signals to control the operation of each of these system components. Such monitoring and control of system components enable remote adjustments to each part of the system, which enables adaptations to varying power demands and unanticipated issues, such as failure of one or more components or other maintenance issues. Remote monitoring allows scheduling of one or more system aspects, such as steam delivery or electricity generation, for example, in anticipation of power demands. The efficient remote control and management of the system may thereby translate to economic savings and time efficiencies regarding management, maintenance, and general operation. The charging system control unit 140 may be co-located at the location where the other system components (e.g., turbine 120, generator 130, charging stations 160a, 160b, 160c) are located, or it may be located remotely from such location.

[0033] Utilizing steam power for electric vehicle charging can significantly reduce costs currently required for installing and using supercharging stations, as well as traditional electric vehicle charging stations. The systems and methods disclosed herein substantially ease the electrical strains that superchargers place on electrical grids, since electric power is no longer required or supplied from electrical grids. In addition, the present invention can significantly reduce and/or eliminate many electricity costs associated with high voltage charging stations. For example, many components traditionally associated with installing and utilizing high voltage charging stations are no longer necessary. Such components include transformers, and high voltage cable lines, which are often installed over substantialand costlydistances.

[0034] In an embodiment, steam generated electricity may be stored in the batteries of an electric vehicle when the batteries are charged, and then later, the vehicle's batteries may be utilized in a vehicle-to-grid system whereby the electrical power in the vehicle's batteries is supplied, e.g., through a home Level 2 charging station with vehicle-to-grid technology, to the electrical grid. In this way, steam generated electrical power is injected into the electrical grid, thereby reducing reliance on fossil fuels. Such an embodiment may also generate a financial profit when the cost of obtaining the steam generated electricity is less than the price which may be obtained for providing electricity to the electrical grid. Referring now to FIG. 4, therein is illustrated an embodiment of a system utilizing the vehicle-to-grid concept. In such a system, vehicle 170 may be interfaced to a vehicle-to-grid (V2G) unit 172 which may be provided as part of the home Level 2 charging system which may be located within or in the vicinity of a home 174. A function of the V2G unit 172 is to convert the electric power stored within the batteries of vehicle 170 into a form of electrical power suitable to be transmitted to the electrical grid 176. This conversion may involve converting DC power into AC power, as well as converting the voltage of the vehicle's stored electric power into a voltage suitable for the electrical grid 176. Some or all of this conversion may be accomplished by way of an AC/DC bidirectional inverter 173.

[0035] Moreover, given the substantial regulatory hurdles often present with installing electric cables and connecting high voltage charging stations to electrical grids, the present invention provides a distinct advantage with respect to installation time and cost, since there exists significantly less regulatory hurdles with respect to components of the disclosed systems. In addition, the present invention may provide substantial economic benefits. High voltage chargers provide a faster, more time-efficient charging capability for electric vehicles compared to traditional or conventional low voltage vehicle chargers. Faster charge times are more attractive to consumers and may help promote and incentivize additional manufacturing and adoption of electric vehicles in the auto industry. Likewise, the green, environmentally-friendly energy source may be even more attractive to consumers and/or manufacturers, given that such technologies will reduce the use of fossil fuels compared to traditional charging methods.

[0036] FIG. 2 is a flowchart depicting aspects of the operation of a steam powered electric charging system in accordance with one or more embodiments. At step 210, the system receives pressurized steam from a steam source. The steam may be delivered from a steam network including at least one steam-generating station or unit, e.g., a boiler, which may be at a same or different location as the turbine/generator complex, and the generating steam for consumption in one or more applications, including the electric charging system as described herein. In other embodiments, pressurized steam may be steam produced from one or more applications generating heat and water vapor. In yet another embodiment, steam may be excess or waste steam after use in one or more steam-consuming applications, such as the present turbine system.

[0037] At step 220, the pressurized steam is delivered to a steam turbine connected to a generator and configured to generate electricity, at step 230, from the energy associated with the pressurized steam. For example, the pressurized steam may flow into the turbine, past a plurality of rotors and stators, to rotate a turbine shaft connected to a generator. The generator utilizes the turbine shaft's rotation within a magnetic field to generate an electrical current directly proportional to the shaft's rotation. In embodiments, after the steam passes through the turbine, it may be recycled back through the system to the steam source and/or steam network, step 215, and again through the turbine to generate more electricity. It will be appreciated that the amount and pressure of the delivered steam may vary according to the type of turbine and/or generator used, the steam network, steam generator, and/or a desired electricity and power output from the system.

[0038] In embodiments, a control unit 134 associated with the generator 130, as discussed herein, may regulate the delivery of the pressurized steam to the turbine. The control unit 134 may, for example, control one or more valves to adjust an amount and/or pressure of the steam to the turbine. In various embodiments, the control unit 134 adjusts the steam based on a determined amount of steam necessary to generate an amount of electrical energy, feedback from one or more components of the system, and/or based on manual input from a user, supervisor, remote control program, etc.

[0039] In step 240, the distribution and/or consumption of generated electricity may be managed for delivery to one or more applications using one or more control units, e.g., charging system control unit 140. The charging system control unit 140 may regulate one or more aspects of the generated electricity, such as identifying one or more applications to receive the electricity, and managing the timing and delivery of electricity to charging stations 160a, 160b, 160c. In various embodiments, the flow of the pressurized steam, for example, through the control of one or more valves, and can be utilized in step 215 to recycle pressurized steam through the turbine system to generate additional power.

[0040] At step 250, one or more electrical applications receive the generated electricity. In various embodiments, generated electricity may be stored in one or more storage units 132, 133, such as electrochemical cells as described herein, for either direct use or energy storage for future consumption. The amount of power and location for delivery may be managed, for example, to prevent damage to the one or more applications using the electric power, ensure that the applications receive appropriate power levels, and ensure that electricity is available for use when needed by the one or more applications. As such, one or more quantifiable measurements related to the energy delivery to the application, e.g., battery capacity (kWh), current battery level, energy delivery rate (kWh), type of charger, etc., may be utilized as feedback, step 245, for subsequent adjustments to electricity distribution and consumption.

[0041] FIG. 3 illustrates an example method for electric vehicle charging, which may be utilized with one or more embodiments of the present invention. The charging system control unit 140 may manage one or more aspects of such methods, in order to determine an amount of electricity to be generated, delivered, and billed. Such methods may be utilized in connection with billing methods, to enable widespread use and consumption of such steam powered charging systems. In an embodiment, a request may be initiated at a charging station, to retrieve energy to charge an electric vehicle. Users may indicate a charging request through one or more input controls, through a remote request, or by physically connecting the electric vehicle to the charging station. In other embodiments, the request may be implemented similar to traditional electrical vehicle station charging methods.

[0042] In embodiments, users may be charged based on an amount of energy, kWh, consumed during the charging process. In other examples, users may be charged based on a time of charging, e.g., during peak or off-peak hours, a length of charging, and the type of charging station (standard vs. supercharger) or time spent at the charging station.

[0043] In the charging method, step 310 determines a capacity of the battery to be charged. This may include calculating a state of charge, which identifies the current battery capacity relative to the maximum capacity. Step 320 identifies information related to the charging station to which the electric vehicle battery is connected, such as a type of charging station, and power delivery capabilities, such as voltage and current.

[0044] Step 330 utilizes the battery capacity and charging station information to determine charging requirements. This may occur, for example, at charging system control unit 140 or a remote computing device, to determine one or more aspects related to charging the electric vehicle battery. Aspects may include an amount of power to be delivered, an optimum current level, and a timing for delivery. Accordingly, based on the determined amount of power required to charge the electric vehicle, one or more of these charging aspects may be managed and adjusted at step 340 to efficiently deliver electricity to the electric vehicle battery. For example, energy delivery may be regulated based on one or more of the type of charging station, a type of battery, the electric vehicle's battery capacity, a current state of charge, and an amount of generated electricity available for consumption. In embodiments, the electricity distribution and consumption management may be managed throughout the process of delivering energy to the electric vehicles/applications, step 345. For example, control of a charging station 160a, 160b, 160c, 160d may be managed to regulate the power flow to the charging station. Similarly, the charging station itself may be regulated to alter one or more aspects of power delivery throughout the charging process. In addition, the charging system control unit 140 in conjunction with control unit 134 of the generator, as disclosed herein, may adjust the operation of a turbine/generator complex to generate a desired or required amount of electricity for the requesting application. In other examples, the electricity management may be based on whether a credit, i.e., payment, has been provided to a charging station 160a, 160b, 160c, 160d to enable delivery to the electric vehicle.

[0045] Subsequently, one or more billing methods may be implemented in response to the energy delivery 360. For example, the charging station 160a, 160b, 160c, 160d may require a user to submit a payment based on the amount of energy delivered to the application, or based on an amount of time required for charging. The billing need not be limited to an amount of energy delivered, and may be based on a plurality of factors related to the system, e.g., steam consumption, etc., or other business and economic factors, such as billing based on the time the vehicle remains at the charging station, or remains at the charging station after the charging process has been completed.

[0046] It will be appreciated that while certain example embodiments have been described, these embodiments have been presented by way of example, for purposes of illustration, and are not intended to limit the scope of the inventions disclosed herein. Other aspects and embodiments will be apparent to those skilled in the art. Thus, nothing in the foregoing description is intended to imply that any particular feature, characteristic, step, module, or block is necessary or indispensable.
