[0070] Presented herein is a smart energy platform, as well as methods of its use for withdrawing and supplying electric energy to a local electric grid. The storage unit systems, “plug-and-play”, are easy to integrate within an existing local grid and distribute the energy on it. As illustrated in FIG. 1, the system is divided in four levels and is described in more detail hereinbelow.

[0071] Level I—The smart energy storage system provides electric energy to the connected appliances and returns the energy to the local grid. The storage units are modular, portable, stackable, electrically chainable, reconfigurable, and rechargeable.

[0072] Level II—The smart adapter system is an add-on breaker panel installed between the existing breaker panel and the electrical load circuit (wired in series) to manage and regulate the energy of a local electric grid. The add-on breaker panel isolates, connects, and monitors some of the circuits of the main breaker panel.

[0073] Level III—The mobile application is powered by the Moduly AI smart platform. It controls the water heater operation, optimizes the smart thermostat, smart HVAC, detects an abnormal high consumption of an appliance in the house, gives energy-saving recommendations based on the user's habits, and adjusts the battery level based on the weather forecast.

[0074] Level IV—The energy provider web interface collects the user's information through a customizable platform. Utilities will shift to a flexible, adaptive, and individual data-driven power grid. Utilities' platform will allow the energy provider to perform load shaping, voltage support, congestion relief, and transport and distribution (T&D) deferral.

[0075] Referring to the drawings, and particularly to FIG. 1, the system 100 is a smart energy platform that comprises a smart energy storage unit 105 (see e.g., FIG. 6) that is connected to the power socket 90 of a local circuit of the house 80 equipped therewith. The system 100 comprises an add-on breaker panel 102 coupled, e.g., hardwired, to the main electric panel 85 which relays power from the energy grid 75 to the house 80, and a software platform that integrates and control the energy storage components and processes, the add-on breaker panel systems, and the other components such as smart appliances 70.

[0076] The smart energy storage unit 105 of the system 100 comprises, as is described in more details later, a DC/DC converter used to charge the storage unit, one or more inverters to withdraw electric energy from the storage to power, e.g., directly connected appliances and/or appliances connected to an electric circuit under control of the add-on breaker panel 102.

[0077] The function of the add-on breaker panel, 102 is to manage and regulate the energy provided by the electric grid. Potential energy sources comprise a vehicle charging station 104, and a solar panel assembly 106 comprising a solar inverter connected to solar panels.

[0078] As described later, the smart energy storage unit system 100, alone and/or in combination, comprises two units: a power control module 210 and a power storage module 220 (see e.g., FIG. 15). The control module of the storage unit is 220 adapted to be connected to a wall outlet thereby securing integration of the storage unit 105 to the existing electric circuit, making it easy to scale, flexible and safe to charge and discharge.

[0079] The battery charger features four stages: a bulk stage, an absorption stage, a pre-float stage, and a float stage. It comprises a secondary power supply system, such as a supercapacitor, to absorb power peaks. It includes communication means, to manage peer-to-peer communication through a standard communication protocol such as I2C and performed through e.g., Bluetooth™, BLE, Wi-Fi, Lora.

[0080] Referring to FIG. 22, a finite-state machine model is implemented to define the different operational modes and their corresponded switch states. The next two modes are electrically constrained that only can happened if the followed condition are meet. A The fast battery recharge mode can only happen if the SW1 is in ON state, SW3 and SW7 are in OFF state. Off-grid house mode can be use only if the SW1, SW3 and SW7 are in OFF state and SW2 in ON state.

[0081] Referring to FIGS. 2 and 20, according to embodiments, the smart energy storage unit comprises an array of electrical switches that connect and disconnect the power outlets based on requirements (see e.g., FIG. 22 for modes of operations comprising up to 6 power-up and off-grid modes and associated switch statuses). An additional function of the array of electrical switches is to allow the flow of electricity between the storage power bus and the grid-tie inverter, off-grid inverter (aka inverter AC power), or the DC/DC converter. Accordingly, switch 111 is designed to activate recharging of the storage unit through the DC/DC converter. The electric switch array 112 is a power bus switch routing the power to the DC/DC converter or to the inverter. The electric switch array 113 is an AC power switch located between the inverters and the grid, wherein each AC outlet has an individual control. The electric switch array 113 is also used to return AC energy to the grid via the main power cord and the control unit. In one embodiment, a switch 114 is also present.

[0082] Referring to FIG. 3, the schematic depicts only selected circuits of the house, in other words the electric circuits coupled to the add-on breaker panel 102 controlling and relaying power between the energy grid 75 and appliances (not depicted). It shows that the add-on breaker panel 102 relays power from the main electric panel 85 to the selected circuits, thereby controlling power (none or all) and direction of the power relayed thereby. It further depicts the potential plurality of power sources (e.g., energy grid 75, solar panel assembly 106, and charging station 104) and potential connection being both potential energy sources and energy consumers (e.g., charging station 104).

[0083] Referring to FIG. 23, the add-on breaker panel 102 is practically installed between the existing breaker panel 85 and the electric load circuit (not depicted on FIG. 23). It comprises: [0084] current/voltage sensors 115 connected circuit; [0085] transfer switch 116 to connect the circuits to the common bus bar, isolating each circuit or connecting it directly to the main panel, and thus to the electric grid; [0086] microprocessor unit 117 that collects and filters the sensor values, shares the collected data with a server database, and locally controls the states of the switches; [0087] component(s) for monitoring the energy production from, e.g., the solar panel and distribution of energy in the circuits where a storage unit is placed; [0088] component(s) for monitoring and regulating the charging process of e.g., the electric vehicle circuit. The control is performed via an API, which receives commands from a platform server featuring algorithm to apply AI to the system; and [0089] a bidirectional EV charger 118 that allows the system to extract energy from e.g., the electric storage of e.g., the electrical vehicle when needed, and operating as an extra energy source when appropriate.

[0090] Referring now to other drawings, and more particularly to FIGS. 6, a smart energy storage unit 105 is depicted according to a first exemplary embodiment. The depicted smart energy storage unit 105 includes a plurality of individual power storage modules 120. The individual power storage modules 120 may be provided in a variety of capacities so that a suitable number of power storage modules 120 can be selected and combined to provide the desired power pack to suit an intended application and load device. According to the type of power module, a power control module 210 comprises one or more batteries of an appropriate technology adapted to be able to connect and thereby be considered for the present purpose as a storage unit. However, according to alternative embodiments, a wide variety of capacities may be provided.

[0091] The system 100 uses an AI training strategy to optimize energy consumption prediction used to manage the components of the system 100.

[0092] According to a realization, the process used for training the data model, aka AI training, comprises the use of four algorithms (a random forest algorithm, a k-nearest neighbor algorithm, a naïve Bayes algorithm, and a linear regression protocol, of initially equal weight). The process obtains thereby an average prediction score according to the current model that is multiplied by the weight of each of the algorithm. This method thereby uses only supervised variables and gives the advantages to each of the algorithms.

[0093] The process comprises to remove a less precise algorithm when the process falls under a precision threshold and to re-integrate the removed algorithm after a preset time to help the AI in avoiding “blind spots”, or in other words some undesired sensitivity to particular conditions.

[0094] Referring to FIG. 4, the schematic depicts a non-invasive load residential identification. The appliance load monitoring and diagnosis system has an on-line load model learning mechanism, and an off-line pattern recognition training. Using the depicted information, the diagnosis system: [0095] provides valuable energy feedback of individual appliances; [0096] provides effective load diagnosis services of excessive building energy consumption, and helps with component-level faulty operation detection; and [0097] provides high-level demand-response and flexibility demand-side management of the utilities interface.

[0098] Referring to FIG. 5, the system 100 comprises a peak load management interface. Therethrough, energy providers can control collective features of the users through a customizable platform. Accordingly, utilities can shift to a flexible, adaptative and individual data-driven power grid. The system 100 allows energy providers to perform load shaping, voltage support, congestion relief and transport and distribution (T&D) deferral. Globally, it allows energy suppliers to scale less energy generation and distribution systems solely on peak consumption.

[0099] Referring to FIG. 5, the system 100 also includes a mobile application that allows the user to setup a smart environment in which the storage unit, the add-on breaker panel, EV charger, a smart thermostat and water heater can be integrated via Wi-Fi into that environment.

[0100] The mobile application allows the user to setup the behaviors preference for each of the smart devices connected, monitor their energy activity and automate their control following a customizable energy management strategy.

[0101] The temperature control of the smart thermostat and smart water heater its reflected as a power shifting from the utility supplier perspective, that can be represented as a demand response action.

[0102] The smart energy storage unit 105 of the system 100 is provided with electronic components (see FIGS. 17 and 21) including (part of battery management unit 315) an input protection circuit, an output protection circuit, a charge controller, a communication controller, and a temperature controller.

[0103] The input protection circuit includes an input port that will shut down when the temperature exceeds a predetermined value (e.g., approximately fifty (50) degrees Celsius, etc.) to protect the battery from being overcharged, from overheating, or to be otherwise damaged.

[0104] The output protection circuit is connected to output connection ports (e.g., inverter connection port, DC connectors, etc.) and other suitable electronic components for delivering electrical power from the battery to the outlet ports. The output connection ports are embodiments in part by output interface modules that are interchangeable, aka removable and settable, based on needs.

[0105] The charge controller circuit regulates the charge to the battery pack 176 (comprising batteries 178 and plate 180, see FIG. 14) and includes protection against an increase of temperature over a limit high temperature.

[0106] The communication controller detects the voltage of the battery pack 176, send to the web service the measured values, and controls the display (e.g., LEDs indicators) that indicates the real-time charge of the battery module (e.g., 20%, 40%, 60%, 80%, Full, etc.).

[0107] The temperature controller includes a temperature sensor that monitors temperature for example by monitoring the ground and DC input, such that when the temperature sensed by the sensor exceeds a predetermined setpoint (e.g., approximately fifty (50) degrees Celsius), it cuts power off.

[0108] According to other embodiments, other control circuits, devices and components may be provided to suit particular applications and functions for the power storage modules 220 of the components of the smart energy storage units 105.

[0109] According to the illustrated realization, the modular nature of the individual power storage modules 220 provides the opportunity to assemble modules into a smart energy storage unit 105 comprising individual power storage modules 220 at least partially nested in a plurality of configurations to customize to a desired load. The smart energy storage unit 105 may at any time be disassembled and reassembled into a different smart energy storage unit 105 in a different configuration to power another or a modified load application. The modular nature of the individual power storage modules 220 permits the smart energy storage unit 105 to be separated into individual power storage modules 220 that are each more readily transported, e.g., by a single individual.

[0110] For example, when desired for use at locations where transport of an assembled smart energy storage unit 105 is impractical, such as e.g., camping, exploration operations, and search and rescue missions, providing power to electrical devices in remote areas where power is unavailable (e.g., temporarily lost—such as following storms or other natural disasters; or non-existent—such as in certain underdeveloped regions in the world, etc.), the disassembled power storage modules 220 may each be carried or otherwise transported by separate members of a group to the location, where the power storage modules 220 of the smart energy storage unit 105 may then be quickly and conveniently assembled into a particular stack of power storage modules 220 resulting in the desired smart energy storage unit 105 that is suited for the intended electrical loading conditions or devices to be powered.

[0111] According to realizations, individual storage modules have various weights, with some of them being lightweight (e.g., A-type control module 205—FIG. 10) while others are more heavy-weighted (e.g., the power storage module 220—FIG. 12). According to other embodiments, the device may be any suitable device intended for use in locations without ready access to a grid-based source of electricity. For example, the device to be powered may be a portable medical device such as e.g., a continuous positive airway pressure breathing machine (C-PAP) that would permit a user with a medical condition (e.g., sleep apnea, etc.) to be able to enjoy outdoor activities or other activities that involve sleeping away from home without access to grid-based electricity. According to other embodiments, the medical device may be any portable device intended to assist with any medical condition that might permit the user to gain mobility by having a readily transportable and remotely rechargeable storage unit power supply system.

[0112] Referring now to particularly FIG. 6, the smart energy storage unit 105 comprises power storage modules 220 that can be disassembled to facilitate transport.

The coupling of the bedding area is provided by the lock mechanism 148 of the top plate 136 of the power storage module 220 and the bottom plate 126 of either the power control module 210 or the power storage module 220. The foregoing assembly can be installed on an optional base plate.

[0123] Referring now particularly to FIG. 10, the A-type control module 205 comprises a retractable 120V connector on the bottom plate (not shown per se but similar to bottom plate 126 of FIG. 11) to ease the transport and the plug-and-play connection to an outlet wall.

The power control module 210 is adapted, when in a common smart energy storage unit 105, to communicate with power storage module 220 (see FIGS. 12 and 13), when present, operating as the master controller.

[0128] It is to be noted that the bottom connectors 186 are designed to be insulated from a surface over which the power module may be laid. The bottom connectors 186 are designed so that no electrical contact can occur with the surface when the smart energy storage unit 105 is placed over a flat surface. A pedestal cover (not shown) can be installed on the bottom of the bottom power storage module 220 to support and to electrically insulate the smart energy storage unit 105.

[0129] According to a realization (not depicted), at least one of the bottom connectors 186 and the top connectors 188 feature either a removable cap or a displaceable cap that can be either removed when needed or automatically displaced when partially nesting one power storage module 220 over another. The cap is an exemplary means to protect and prevent contact with the connectors when not in use.

[0130] According to an embodiment, the connectors 186, 188 are adapted when coupled to both transmit power between the modules, and to operate as a communication interface, thus to exchange operation signals between the modules.

[0131] Referring now to FIG. 12, a LED light (not shown) is present around the power storage module 220, between the bottom plate 126 and the top plate 136 of the power storage module 220.

[0132] Referring to FIG. 8, examples of mountable and releasable interface modules 202 are depicted, wherein each of these interface modules 202 can be mounted to a power control module 210 (e.g., power control modules 210 depicted on FIGS. 12 and 13), be dismounted from the power module and replaced with another interface module 202, wherein spring probe connectors are used to connect interface. The spring probe connectors are used such that the system is adapted to automatically recognize the nature of the mountable and releasable interface modules 202 and to adapt the power transmitted to the mountable and releasable interface modules 202 accordingly.

[0133] An exemplary list of interface modules comprises, while not limited to, an AC 110 Volts module, an AC 110 Volts/220 Volts module, a USB 3.0 module, a 12V socket module, an electric car module comprising an SAE J1772 connector, and a 5-24 v power jack connector.

[0134] Referring to FIGS. 13, 15 and 16, a power control module 210 and a power storage module 220 and/or two power storage modules 220 are stackable (e.g., FIG. 15) by placing the top one (e.g., power control module 210) partially nested over the top of the power storage module 220 and setting them together. Pressure switches 241 activate the lock mechanism 148 of the top plate 136 to the bottom plate 126. To release one from each other, one operator may insert fingers into the pressure switches 241 (part of a release mechanism). You can also unlock the power control module 210 from the power storage module 220 by pressing a touch sensor of the handle 140.

[0135] Referring to FIGS. 17 and 21, the shown diagrams depict functional components managing a smart energy platform, including the smart energy storage unit 105 and add-on breaker panel 102 connected to the power grid 310, in accordance with aspects of the present disclosure. The diagram shown in FIG. 21 optionally includes a UPS system 305 connected to the AC power socket 90.

[0136] It is to be noted that for the present description the singular is used even though some components may be present in multiple instances in the smart energy storage unit 105, since, when combined, they operate in the same fashion towards a common objective.

[0137] In realizations, the smart energy storage unit 105 comprises a battery pack 335 composed of single-cell storage units located in a single power storage module 220 or distributed over a plurality of power storage modules 220.

[0138] The battery pack 335 is controlled by the battery management unit 315 distributing power available in the battery pack to the different power outputs (Off-grid Inverter AC power output 325, Grid-tie inverter 365 and Charger DC power output 330). The battery management unit further monitors and controls power exchange with the AC power socket 90 when the smart energy storage unit 105 is charging.

[0139] Battery monitoring sensors 340 oversee monitoring, through e.g., sensors, the distribution, aka outputs and inputs of power, to ensure that all operations are performed within safe limits.

[0140] A power control unit 320 is connected to the battery management unit 315. The power control unit 320 is responsible for user interfaces, comprising the communication unit 355 used by users to input information and/or commands with the user interface 345 in the smart energy storage unit 105, the user interface 345 responsible to provide information to the user on the status and operation conditions of the system 100, and a communication unit 355 responsible for communication of the system 100 with external agents, such as a Wi-Fi router, web sites, apps, etc. The communication unit 355 operated in cooperation with a secure communication protocol responsible to ensure that all communications exchanged are safe, that the system 100 operates in accordance with commands from the appropriate users.

[0141] For example, the communication unit 355 may be an example of a component adapted to transmit the power usage data to a web service 360 or data to the system 100; and receive an energy usage configuration based at least in part on transmitting the power usage data.

[0142] In preferred realizations, the communication unit 355 comprises a transceiver (not depicted) adapted to communicate bi-directionally, via antennas, wired, or wireless connections as described above. For example, the transceiver may represent a wireless transceiver and may communicate bi-directionally with another wireless transceiver. The transceiver may also include or be connected to a modem to modulate packets and provide the modulated packets for transmission and demodulate received packets. In some examples, the transceiver may be tuned to operate at specified frequencies. For example, a modem can configure the transceiver to operate at a specified frequency and power level based on the communication protocol used by the modem.

[0143] The system 100, wherein the connected devices may consist of power-consuming devices (e.g., a computer, an appliance, a tool, a router, etc.), in power-feeding devices (e.g., a grid-connected AC power socket, a solar cell system, an electric vehicle) and hybrid devices (e.g., an electric bike design to being charged and to charge in a need-based manner or in a cyclic manner).

[0144] When the system 100 is present, the smart energy storage unit 105 and the add-on breaker panel 102 can be monitored through Wi-Fi communication, and more particularly through either a user interface 345 or the utility interface 350 as examples.

[0145] The user interface 345 or the utility interface 350 may include, for example, profile management, information on operating the system 100, power usage, commands to remotely control (e.g., turn off) aspects of all appliances or devices connected, a notification center and more information.

[0146] FIGS. 18 and 19 schematically depict an exemplary deployment of one or more smart energy storage unit 105 in a household, wherein, based on the needs. For example, the nominal power of a smart energy storage unit 105 designed to be used in a living room will be according to the number of power storage module 220 stacked. Each room with a smart energy storage unit 105 can have a different power stack.

[0147] While preferred embodiments have been described above and illustrated in the accompanying drawings, it will be evident to those skilled in the art that modifications may be made without departing from this disclosure. Such modifications are considered as possible variants comprised in the scope of the disclosure.
