The North American power grid was once called the ‘supreme engineering achievement of the 20th century.’ Unfortunately, the power grid is quickly aging such that outages and inefficiencies result in great costs to end users. In addition, terror activities and malicious computer code threaten denial of service to the nation's critical infrastructure.
A growing movement to provide clean energy, utilizing such sources as wind, currently suffers from significant inefficiencies due to limitation within the power grid. Commercial wind farms often produce much greater energy than is realized because the transmissions lines cannot accommodate the amount of energy produced, thereby resulting in large amounts of wasted effort.
Residential applications are often seen as impractical due to costs, lack of providing enough energy during peak demand, and wasted energy during off-peak times. In addition, there is no application that provides two-way communication between consumers and the distribution source.
Current efforts to develop a smart grid are ongoing. A smart grid may be an electrical grid that uses information and communications technology to gather and act on information, such as information about the behaviors of suppliers and consumers, in an automated fashion to improve the efficiency, reliability, economics, and sustainability of the production and distribution of electricity.
The developments in the smart grid do not include providing the end user the ability to utilize and manage distributed energy sources. Further, there is no system that currently provides the capability of the distributed energy sources, such as in residential application, to return unused energy to the power grid, or store excess energy for later use by the consumer. Although smart meters allow electric utility companies to collect data at the consumer site, there is not a system that provides the consumer, or other interested stakeholders, the ability to collect usage and generation data, to deliver electricity more efficiently and detect problems within the system, and provide information that allows for strategic placement of distributed generation sources for overall performance improvement.
There exists a need to integrate electric power generation and electric storage techniques into a single delivery system. There also exists a need to connect with a meter to create a home electric power source with an ability to provide a two-way communication between consumers and the distribution source.
Embodiments of the present invention relate to an energy storage system and an energy management system. The energy storage system allows for users to store, manage and provide energy to an inhabitable environment. The energy management system generates energy management data that informs a user about the historical trends of, predictions of and suggestions for energy usage.

As described above, a smart grid may be an electrical grid that uses information and communications technology to gather and act on information, such as information about the behaviors of suppliers and consumers, in an automated fashion to improve the efficiency, reliability, economics, and sustainability of the production and distribution of electricity.
To provide a general overview of a smart grid system,
A smart grid is associated with a smart meter.

Embodiments of the present invention build upon the smart grid system, as well as apart from the smart grid system, to address, at least, the deficiencies of the smart grid system.
In embodiments of the present invention, an energy storage system facilitates the storage, management, or provision of energy associated with an inhabitable environment. An inhabitable environment may include, but is not limited to, a workplace, residence, commercial or industrial environment. Generally, an inhabitable environment may comprise a heating system, a cooling system, and/or an electrical outlet. A heating system is generally a mechanism for increasing and/or maintaining temperatures at a specified degree by using thermal energy within a home, office, or other dwelling. A cooling system is generally a mechanism for decreasing and/or maintaining temperatures at a specified degree by using a refrigeration cycle. In some embodiments, an energy storage system functions as a local energy storage system. In such embodiments, the energy management system may be installed into an inhabitable environment at or near a breaker panel. In other embodiments, the energy storage system may be located remotely from the inhabitable environment. As used herein, an energy component may refer to an electrical outlet and/or an electrical device. An electrical outlet is an outlet associated with an inhabitable environment through which energy may be provided. An electrical device is a device through which energy may be consumed. Examples of an electrical device include a light switch, a television, a heating system and a cooling system.
Referring to
In some embodiments, an energy storage system may include a control box 320. Further, the control box 320 may include a computing device similar to that of computing device 100 found in
In various embodiments, the energy storage system may store energy in two types of storage devices, a lithium ion battery and capacitors. There are advantages associated with each type of storage device. At least one advantage of storing energy in a lithium battery includes the ability of the lithium battery to hold a steady flow of continuous power. At least one advantage of a capacitor includes the ability of a capacitor to provide energy in large quantities. For example, a large appliance may require a large amount of energy when first turned on. In such instance, a capacitor is able to provide the large appliance the necessary energy without disruption of the power flow. The energy storage system may store enough energy to power an entire home during peak electricity demand periods. In some embodiments, an energy storage system may include only a lithium ion battery. In other embodiments, an energy storage system may include only a capacitor.
In some embodiments, an energy storage system allows a user to manage the stored energy. In some embodiments, the energy storage system allows a user to control the energy provided to devices associated with the inhabitable environment. For instance, a user can manage the energy provided to each room of a home. Using the energy storage system, a user can designate that no energy be provided to an unfinished basement of the home, or designate that more energy be provided to a living area of the home.
In one embodiment, an energy storage system is configured to gather and provide energy related data. Such energy related data may include billing statements, safety notices, alerts, historical pricing data of energy provided by a utility provider, anticipated utility pricing data of energy provided by a utility provider, local, national and worldwide weather related information such as current conditions and forecasts, and historical energy usage data of a consumer. Energy related data may also include historical energy usage data of an inhabitable environment and of each of the components associated with the inhabitable environment. The historical energy usage data may include measurements and times of energy usage for and determined anticipated measurements and times of energy usage for each component of an inhabitable environment. The energy storage system may gather the energy related data information from a user, electrical outlets, and/or electrical devices. Further an energy storage system may gather energy related data by communicating with a utility provider, weather resource, or other entities related to energy consumption.
In some embodiments, the energy storage system may include a graphical user interface at a computing device located in the inhabitable environment. The graphical user interface may facilitate the interaction between the user and the energy storage system. For instance, a user can use the graphical user interface to direct energy to flow through the energy storage system or to by-pass the energy storage system. In such embodiments, the energy storage system gathers information from a user through the graphical user interface. In some embodiments, the energy storage system may provide energy related data by electronic communication over a network, such a by email, text, phone call, or the Internet. In other embodiments, the energy storage system may include a display device and provide energy related data through the display device.
In some embodiments, an energy storage system may be integrated with a smart meter, a smart grid, or both.
As shown in
An energy storage system may store various amounts of energy. The amount of energy an energy storage system stores may depend on energy related data, described above. For instance, an energy storage system may store energy based on the amount of energy required by an associated inhabitable environment during a specific period of time. In another instance, the amount of energy an energy storage system stores may be based on a weather forecast. For example, a weather forecast may anticipate a two-day snow storm. Based on the weather forecast an energy storage system may store an amount of energy that can last an inhabitable environment for two days. Further, the amount of energy an energy storage system stores may depend on user preferences.
User preferences detail aspects of energy management a user may prefer. User preferences may include the times of day energy should stored and provided. User preferences may also include preferred cost of energy for a specific time period. Further, user preferences may include specific components and specific locations of an inhabitable environment to which energy should be provided.
An energy storage system may store energy during various times of the day. The time periods during which an energy storage system store energy may depend on the cost of energy, the necessity of energy, user preferences and/or energy related data. For example, an energy storage system may store energy when the rate of energy is the least expensive.
An energy storage system may provide energy during various times of the day. The time period during which an energy storage system may provide energy may be based on energy related data, user preferences, mapping data, and a threshold amount of energy stored in the energy storage system. Conversely, the time period during which the energy storage system may be bypassed is also based on energy related data, user preferences, mapping data, and a threshold amount of energy stored in the energy storage system. Further, an energy storage system may cease to provide energy based on energy related data. For instance, if a component associated with an inhabitable environment requires more energy than is stored in the energy storage system, the energy storage system may not provide the energy. Instead, the energy storage system may be by-passed allowing energy to be provided from an outside source, such as the utility provider. However, if the energy storage system contains the minimal amount of energy require for a component, the energy storage system may provide the required amount of energy. In another instance, a user preference may indicate that a certain component should not receive energy from the energy storage system, causing energy not be provided to that certain component by the energy storage system. In some embodiments, the energy storage system may not provide energy if an amount of stored energy meets a minimum threshold. For instance, an energy storage system may cease to provide energy once the energy storage system has only 5 KJ of energy stored, in which case the energy storage system may be by-passed to allow for outside energy to be provided. The minimum threshold amount of energy may be determined based on energy related data and/or a user preference.
Energy management instructions may be provided to an energy storage system instructing the energy storage system to provide a flow of energy to a specific device, outlet, and/or location within the inhabitable environment. An energy management instruction may also provide instructions on a time of day to direct the flow of energy and an amount of energy that may be directed to an electrical outlet. An energy management instruction may be based on preferences provided by a user, energy related data, or an amount of energy stored in an energy storage system. Additionally, an energy management instruction may be provided by a user or by a smart meter.
An energy management system provides for the management of energy in an inhabitable environment. The energy management system generates energy management data that informs a user about the historical trends of, predictions of, and suggestions for energy usage.

It should be understood that any number of energy management functions, data stores, and electrical components may be employed in computing system 700 within the scope of embodiments of the present invention. Each may comprise a single device/interface or multiple devices/interfaces, memory, disks, hard drives and tapes, cooperating in a distributed environment. The components/modules illustrated in
The data store 730 is configured to store data associated with energy flow of an inhabitable environment. Specifically, data store 730 may include energy usage data, energy management data, and mapping data. In embodiments, the data store 730 is configured to be searchable for items stored in association therewith.
Data store 730 may be storage data that comprises data associated with energy flow of the inhabitable environment. For example, data store 730 may be located at and comprise data associated with a utility provider, a smart meter, energy storage system, a consumer residence, or exist in a standalone environment.
The energy management function 710 is configured to generate energy management data. The energy management data includes, but is not limited to, cost-savings information, behavioral impact information, anticipated energy usage data, operational data, and notices associated with the consumer. Energy management data also includes cost-savings information and behavioral impact information associated a utility provider. Further description of energy management data is provided below. Using the energy management data, a user is able to manage the energy provided to a consumer and used by a consumer. As illustrated, the energy management function 710 includes an input component 782, analyzing component 784, generating component 786, and output component 788.
The input component 782 of the energy management function 710 is configured to receive or retrieve data for use in generating energy management data. Typically, the input component 782 retrieves data from data store 730. However, the input component 782 may receive or retrieve input from other sources as well, such as from a user of the energy management function, electrical component 740, or other locations within and outside network 700.
The analyzing component 784 of energy management function 710 is configured to analyze the data received by input component 782. The generating component 786 is configured to generate energy management data based on the analysis provided by the analyzing component 786.
The output component 788 is configured to communicate the generated energy management data to a user or a component located within or outside network 700. Further, the output component may also provide energy usage data or other data related to the energy usage and flow associated with an inhabitable environment.
As stated earlier, an inhabitable environment may include, but is not limited to, a workplace, residence, commercial or industrial environment. Energy usage data may include historical pricing data and anticipated pricing data of energy provided by a utility provider. Historical pricing data include the time, location, and price of previously provided energy of a consumer. Anticipated pricing data includes prices of energy currently provided and energy to be provided. In some embodiments, the “pricing data” may be referred to as “rate information.” Additionally, energy usage data includes historical energy usage data of a consumer. Historical energy usage data of a consumer includes the time, place, and amount of energy previously used or consumed by a consumer at a residence, workplace, commercial or industrial environment.
Mapping data may be provided to system 700 by direct input from a user at input component 782 or retrieved from data store 730. Mapping data includes a mapping of an electrical device to an electrical component. The mapping of an electrical device to an electrical component is shown in
Cost-savings information includes information associated with a consumer and includes peak time rebate information, dynamic pricing, and suggestions on how to reduce the amount of cost of energy. Peak time rebate information includes information when a reduction of the use of energy is advantageous, especially on peak-event day when electricity demand is high. Reducing energy use on such days may save a consumer money. Dynamic pricing includes information about time-based pricing of energy, where the price of the energy varies according to the time of the day, day of the week, date in the month, or month in the year. For example, using the mapping information, cost-savings information may include the amount of energy consumed when using a clothes dryer during the day versus at night. The cost-savings information may include a suggestion on how much money may be saved by using the clothes dryer at night. Cost-savings information may also include suggestions on what energy source to use. For instance, an energy storage system may have stored energy at the price of X dollars. The current price to receive energy from a utility provider may cost Y dollars where X is less than Y. Cost-savings information may include a suggestion to use cheaper stored energy instead of more expensive energy provided by the utility provider.
Behavioral impact information include information on the use of energy, such as the amount of energy used at a specific time, by an electrical device, by an electrical component, or suggestions on how to use less or more energy.
Anticipated energy usage data include information about predicted future use of energy based on previous patterns and methods of using energy. The notices provided by the energy management function includes billing statements, local, national and worldwide weather alerts, current conditions and forecasts, and energy alerts.
Cost-savings information of a utility provider includes information related to the amount, time, and consumer energy that is provided to the consumer, how that energy was used by the consumer, and how energy may be provided to the consumer in a cheaper manner. For instance, a consumer may have an energy storage system and use the most energy in the evening. It may cost more for a utility provider to provide energy to the consumer in the evening than in the morning. Cost-savings information may include a suggestion to provide a consumer with the required amount of energy for the evening in the morning such that the user may store the energy during the morning. Behavioral impact information associated with the utility provider includes information about the time, consumer, and amount of energy provided.
In some embodiments, system 700 may include a graphical user interface that allows a user to interact with the energy management system. In such embodiments, the output of energy usage data or energy management data, may be presented on the graphical user interface. In some embodiments, output of energy usage data and energy management data may be provided to a user through other forms of electronic communication such as, but not limited to an email, a display device, a phone call, a text message, or an audio device.
Energy management system 700 may be configured to use home area network (HAN) integration or Green Button integration in order to enable users to manage their energy consumption and allows for the energy management system to gather and generate efficient energy usage data and energy management data. Green Button deals with the idea of providing utility customers with easy and secure access to their energy usage information in a consumer-friendly and computer-friendly format. Further, the energy management system 700 may be configured to interact with consumers of energy and users of the system through various means, such as, but not limited to an email, a display device, a phone call, a text message, an audio device, and social media outlets.

In an implementation of an embodiment of the present invention, the energy storage system may be installed inside a residence at or near a breaker panel. The control box sends a signal to the smart meter to use the energy storage system or to by-pass the energy storage system for normal electric delivery. The energy management system works by collecting electric power during off-peak periods and storing it in two types of rechargeable battery delivery methods. As described above and particular to an embodiment, a bank of lithium batteries holds a steady flow of continuous power while a bank of ultra capacitors holds electric power that is released in bursts to jump start larger power hungry electrical components, electrical devices, or both. The bank of lithium batteries and ultra capacitors can combine into a seamless electric delivery system to power home appliances and supply daily electricity needs. The energy storage system can utilize a robust energy management system in order to provide a user comprehensive communication tools. Using the energy storage system, energy management system, or both, users can turn on/off or dim any light switch or control AC outlets. Further, users can control any plug-in electrical device in a residence 24 hours a day, from any web-enabled computer, smart phone, or other mobile device.
Explained further, the energy storage system contains a capacitor bank of ultra capacitors (UC) for DC storage to be converted to AC on demand. The UC bank holds electricity that discharges quickly and with burst of power when needed. This type of system is designed to power devices that require 3-7 times more energy for start-up surge, such as air conditioners and furnace fans. Generally, a capacitor comprises a low amount of internal resistance and can discharge quickly but may be unable to store a large amount of energy at a given time. Described further, the energy storage system contains a lithium ion battery bank to deliver smoother, more constant AC to electrical components, electrical devices, or both. Generally, a battery has a higher internal resistance than a capacitor. A battery stores electric power that is released continuously to power low consumption devices like a clock/radio or the clock/timers on appliances. The control box may be configured to receive or provide commands to the inverter to release a continuous flow of electricity from the lithium ion bank and each time a device is turned on or a light switch is turned on a command is sent to the proper inverter to release more battery power.
In an implementation of an embodiment of the present invention, the entire residence can be powered during peak electric demand periods. In embodiments, users can control each device that uses electricity. An energy storage system, energy management system, or both can send email notices and alerts to users via computer, mobile device, or both. The present invention integrates with smart meters to connect to the smart grid for two-way communication. As described above and particular to certain embodiments, the energy storage system accepts energy from solar systems, wind systems, and geothermal systems for off-grid power.
In embodiments, the energy storage system connects directly to the electric power of a residence in an area at or near a breaker panel. The control box of the energy storage system communicates with the smart mater to turn off electric power at the breaker panel and turn on the stored energy delivery system allowing the energy storage system to supply energy to a residence by an integrated bank of batteries.
In certain embodiments, the energy storage system includes a wireless router, wi-fi and RFID enabled control box with firmware, AC to DC charger, DC to AC converters, a bank of series of lithium ion batteries, and a bank of ultra-capacitors. The energy storage system provides compatible wall outlets, wall switches, sensors, and optional electrical devices such as video cameras, and remote deadbolt locks.
In an implementation of an embodiment of the present invention, the energy management system uses radio wave technology to send and receive signals from electrical components, electrical devices, or both. The energy management system can include instructions for system commands to perform specific functions such as measuring electric output of each outlet, measuring electric demand from each electrical device, heating, ventilation, and air conditioning (HVAC) units, light fixtures, and all other demands on a residence's electric use. The radio frequency identification (RFID) technology can travel through floors, walls, and ceilings.
The energy management system allows for consumers and utility providers to see electric usage from the source (e.g. power station) all the way to the electrical device, such as a refrigerator. The energy management system allows utility providers to drill down to each consumer's precise energy needs, for example, the energy needs of a single electrical outlet. This information is beneficial for load balancing projections. The energy usage data collection methods would occur via secure protocols and would be seamless to the consumer.
In embodiments, the energy management system provides a consumer the ability to control every electrical component, electrical device, or both in their inhabitable environment. A consumer is able to choose activities like turning on an entryway light at a certain time or turning on an electrical outlet where a crock-pot is plugged in order to start dinner two hours before leaving work. The energy management system can send reminder notices to all types of mobile devices.
The present invention controls operation of energy flow and determines where to route or store energy. The invention captures electricity usage data at the demand source and returns the data to the energy storage system, energy management system, or both. In an embodiment, energy is routed to a consumer through the existing energy source. In another embodiment, energy is stored for later use. In yet another embodiment, energy from an original consumer is returned to a utility company for later consumption by a different consumer.
Many different arrangements of the various components depicted, as well as components not shown, are possible without departing from the spirit and scope of embodiments of the present invention. Embodiments of the present invention have been described with the intent to be illustrative rather than restrictive. Certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations and are contemplated to be within the scope of the claims.
