PORTABLE POWER STORAGE SYSTEM AND METHOD

BACKGROUND

The field of disclosure relates generally to a power storage system and, more particularly, to a portable power storage system with a rechargeable battery.

Power generation and storage devices are constantly evolving as the industry seeks to produce devices with increased power output and better fuel efficiencies, all while reducing the devices' impact on the environment. Currently, fossil fuel-based generators are the most prominent power generation and storage devices for use in areas where grid electricity is not readily available.

However, fossil fuel-based generators have several major drawbacks and in some industries those drawbacks have major financial and work product impacts. In a non-exhaustive list, fossil fuel-based generators produce exhaust that is harmful to the environment and dangerous to humans and animals when used within confined spaces, the generators are loud and may need to be placed away from the working area, the generators require regular maintenance, the generators may produce “dirty” power that may damage some equipment, and the generators are not easily portable once hooked up with enough equipment to transform output electricity into a safe input for some equipment (e.g., higher end equipment). “Dirty” power is defined as “an abnormality in the power quality that is being delivered to a system” and “these abnormalities can include low power factor, voltage variations, frequency variations, and surges.” (See https://www.tesengineering.com/electrical-engineering-what-is-dirty-power/).

In some specific industries, for example, events (e.g., fair, concerts) or production sets, fossil fuel-based generators have additional drawbacks to producing harmful chemicals. For example, given the noise output of a fossil fuel-based generator, the generator may be situated at a location far enough away from the event or production set that the noise does not impact the performance (e.g., fair, concert, speech, or taping of a movie/show). The added distance requires additional cabling and equipment to span that distance, which may be several hundred feet (e.g., 400 feet). It is not unusual for production sets, for example, to spend thousands of dollars in cabling per generator to deliver power from the remotely positioned generator to the production set. Despite the distance, production companies may still filter out the noise after filming.

In addition to the distance, higher end equipment including, but not limited to, speakers, lights, cameras, microphones, computers and the like require quality power inputs in order to function at a high performance and without damaging the equipment. Fossil fuel-based generators have long produced “dirty” power that routinely requires additional equipment to filter and clean the power before it is introduced into, for example, the production equipment. The additional filtering equipment increases the production costs, lengthens the set-up times, and severely reduces the portability of the generator.

Therefore, there is a need in the art for a portable, low cost, and quiet power storage system.

For example, FIG. 2 depicts power storage system 10 with one rechargeable battery 14. FIG. 3 depicts power storage system 10 with two rechargeable batteries 14. Although FIGS. 2 and 3 depict power storage system 10 with one and two rechargeable batteries 14, respectively, it should be understood that power storage system 10 is scalable to accommodate a plurality of rechargeable batteries 14, based on the desired need. Therefore, the description of power storage system 10 is not limited to a specific number of rechargeable batteries 14, unless stated otherwise. Moreover, singular use of “rechargeable battery” when describing various systems/components of power storage system 10 does not limit the discussion to one battery, unless stated otherwise.

FIGS. 17-25D depict power storage system 300. Power storage system 300 is related to power storage system 10 and each may share features and/or components. Thus, it should be understood that power storage system 10 may include features and/or components described in relation to power storage system 300, although those features and/or components may not be depicted in the figures. Similarly, power storage system 300 may include features and/or components described in relation to power storage system 10, although those features and/or components may not be depicted in the figures. Therefore, in discussing power storage systems 10, 300, terminology and reference numbers may be used interchangeably without departing from the spirit/scope of this disclosure. Where features and/or components from power storage system 10, 300 are omitted, but are discussed/depicted in relation to the other power storage system 10, 300, it should be understood that those features and/or components may be included within power storage system 10, 300, unless expressly stated or the context indicates otherwise. It should be understood that reference to power storage system 10 or 300 with regard to additional features, components, or functionality is intended to include the other power storage system 10 or 300, unless expressly stated or the context indicates otherwise.

The outer walls may include a variety of components/features depending on the desired size and configuration of power storage system 300, as discussed in more detail throughout this disclosure.

Outer walls may include a front wall, a back wall, and two sidewalls, which may be connected to the front and back walls. For example, front wall 310 and back wall 312 may be oppositely positioned from each other. In some instances, front and back wall 310, 312 may be parallel to each other. Positioned between front and back wall 310, 312 may be two sidewalls (e.g., left sidewall 314 and right sidewall 316). Left and right sidewalls 314, 316 may be oppositely positioned from each other. In some instances, left and right sidewall 314, 316 may be parallel to each other. In some instances, left and right sidewall 314, 316 may be substantially perpendicular to front and back wall 310, 312. The perimeter of the outer walls, when assembled, may resemble base 306. Body 308 may further include barrier (see 27 of FIG. 2) mounted within the outer walls and between rechargeable battery 14 and electronic system 100. Barrier 27 may separate electronic system 100 from rechargeable battery 14, for example, in the event of battery discharge and/or thermal runaway from rechargeable battery 14. At least a portion of barrier 27 may be manufactured from a fire-retardant material (e.g., metal, cement board, calcium silicate board).

Lid 318 may at least partially engage with one or more of the outer walls and provide a covering to movable cart 302. For example, lid 318 may at least partially engage with front wall 310 and back wall 312, either directly or indirectly. In some examples, lid 318 may at least partially engage with left sidewall 314 and right sidewall 316, either directly or indirectly. Body 308 may further include one or more support structures 320 (see FIG. 28B) to support lid 318. Support structures 320 may be arched to accommodate lid 318. Support structures 320 may be mounted with respect to left and right sidewalls 314, 316. Lid 318 may at least partially engage with one or more of the following including, front wall 310, back wall 312, support structures 320, left sidewall 314, and/or right sidewall 316, either directly or indirectly.

Power storage system 300 may further include frame 340 mounted with respect to movable cart 302. Frame 340 may be removably attached, either directly or indirectly, to movable cart 302. Frame 340 may be semi-permanently or permanently mounted with respect to movable cart 302. Frame 340 may be mounted at least partially external to base 306 and/or body 308. In some instances, frame 340 may be mounted entirely external to base 306 and/or body 308. In other instances, frame 340 may be mounted at least partially internal of base 306 and/or body 308. Frame 340 may be an external frame relative to base 306 and body 308, an internal frame relative to base 306 and body 308, or an external frame and an internal frame relative to base 306 and body 308. Frame 340 may provide rigidity to power storage system 300, and more particularly, to movable cart 302.

Frame 340 may be fabricated from a variety of materials/stock having various shapes and cross-sections, including but not limited to, square tube, rectangle tube, round tube, pipe, I beam, H beam, rod, channel, strut, strips, flats, bars, honeycomb, and combinations thereof. Frame 340 may be fabricated from a variety of materials, including but not limited to, metal (e.g., steel, aluminum, titanium, iron, copper), metal alloys (e.g., ferrous alloys, aluminum alloys, nickel alloys, copper alloys, titanium alloys), plastic, polymers (e.g., thermoplastic polymers, thermosetting polymers, elastomers), fiberglass, rubber, composites (e.g., particulate composites, fibrous composites, laminated composites), and combinations thereof.

In one embodiment, power storage system 300 may include frame 340 which is positioned external to base 306 and body 308. Frame 340 may include a plurality of horizontal members, vertical members, angled members, and combinations thereof. For ease of explanation and in a non-limiting example, frame 340 includes horizontal members 342 and angled/vertical members 344. Frame 340 includes a plurality of horizontal (or nearly horizontal) members 342 and a plurality of angled (or vertical) members 344. For descriptive purposes, if wheels 32 are considered the “bottom” of power storage system 300, then lid 318 is considered the “top” of power storage system 300. Angled members 344 may extend in the direction of lid 318 from base 306. Angled members 344 may be permanently or semi-permanently attached to base 306. For example, base corner 307 of base 306 may attach directly or indirectly to frame 340. Base corner 307 may include bumpers (e.g., rubber, plastic).

Frame 340 may define a plurality of triangular structures 346 that are constructed by a plurality of angled members 344 and/or horizontal members 342. Triangular structures 346 may provide structural support for frame 340 and power storage system 300.

However, any one of the previous benefits may be accomplished by any member 342, 344 of frame 340. In some instances, triangular structure 346 may be supplemented with and/or replaced by a gusset plate (not shown).

The plurality of angled members 344 and/or triangular structures 346 may be connected to one or more horizontal members 342, which may extend parallel or nearly parallel to base 306. Horizontal members 342 and angled members 344 may define openings for ease of access to body 308. For example, frame 340 may be positioned such that access panels 350, power panels 102, 114, 116, and display 104 are, at least in part, accessible without removal of frame 340. It should be understood that frame 340 may be constructed in a variety of configurations without departing from the spirit/scope of this disclosure.

Movable cart 302 may further include and/or define lifting and/or tie down components and/or features. In one instance, base 306 may define channels 348 configured to engage with pallet forks. Channels 348 may extend between opposing sides of base 306. Channels 348 may be spaced and sized to interface with pallet forks. Movable cart 302 may also include and/or define areas for lifting (e.g., hoisting) power storage system 300 and/or areas for strapping (e.g., tying down, securing) power storage system 300. In some embodiments, base corner 307 may include and/or define areas for lifting (e.g., hoisting) power storage system 300 and/or areas for strapping (e.g., tying down, securing) power storage system 300. For example, base corner 307 may include tie down anchors, hoist rings, shackles, hooks, D-rings, and combinations thereof.

In some instances, base 306 may include one or more access panels 350. Access panel 350 may be removable such that access panel 350 is detached entirely from body 308 and/or may be openable such that the component/features behind access panel 350 are accessible, but access panel 350 remains directly or indirectly attached to body 308. For example, access panel 350 may be hinged to body 308. Access panel 350 may be lockable. Body 308 may also include and/or define sidewall tabs 352 for engagement with access panel 350. Access panel 350 may directly or indirectly engage with sidewall tabs 352 when access panel 350 is installed on movable cart 302. Additionally, access panel 350 may be removed from sidewall tabs 352 to access components/features behind access panel 350. In some cases, removal of access panel 350 may at least partially expose rechargeable battery 14. Unless otherwise stated, access panel 350 may include and/or define features and/or elements that other walls 310, 312, 314, 316 of body 308 may depict, including but not limited to, designs, graphics, logos, alphanumeric characters, symbols, and combinations thereof.

The footprint of power storage system 10, 300 is designed to be easily transported and maneuvered. In some instances, components/features may be relocated to a different outer wall in order to accommodate the desired maneuverability and transportability. In other instances, components/features may be relocated to a different outer wall based on the desired electrical output of power storage system 10, 300. Thus, various footprints of power storage system 10, 300 may accommodate various rechargeable batteries 14 and therefore, various electrical outputs. The footprint refers to the outer dimensions of the entire system and, in some cases, components/features that may extend beyond the outer portions of body 18, 308. In some embodiments, footprint may refer to the dimensions of base 16, 306 of movable cart 12, 302. In specific instances, the footprint of base 16, 306 of movable cart 12, 302 enables a plurality of power storage systems 10, 300 to fit within existing transportation vehicles (e.g., van, truck). For example, the existing transportation vehicles may refer to vehicles used by production companies to deliver equipment to and from a production site. The transportability will be discussed in more detail below and with reference to FIGS. 14-16.

Power storage system 10, 300 may define various footprints in order to comply with storage or transportation criteria (e.g., to fit within existing transportation vehicles). In some instances, each footprint variation of power storage system 10, 300 may share a dimension (or a multiple thereof) to comply with storage or transportation criteria to efficiently maximize storage/transportation space. For example, each footprint variation of power storage system 10, 300 may share at least one of the following dimensions (or a multiple thereof), including width, length, or height, to comply with storage or transportation criteria. As used herein, “multiple” may refer to a dimension that can be multiplied or divided by the number of power storage systems 10, 300 and will arrive at the original number, without a remainder. For example, if power storage system 10, 300 has a width of 40 centimeters (“cm”) (about 15.75 inches (“in”)), a multiple thereof would be 10 cm (about 3.94 in). Therefore, four power storage systems 10, 300 having a width of 10 cm (about 3.94 in) would fit within the space occupied by power storage system 10, 300 having a width of 40 cm (about 15.75 in). In another example, a multiple of power storage system 10, 300 having a width of 40 cm (about 15.75 in) is 80 cm (about 31.5 in). Therefore, power storage system 10, 300 having a width of 80 cm (about 31.5 in) would occupy a space similar to two power storage systems 10, 300 having a width of 40 cm (about 15.75 in).

In a non-limiting example, power storage system 10, 300 may define a width of about 75 cm (about 29.53 in), a length of about 75 cm (about 29.53 in), and a height measured from a floor surface of about 125 cm (about 49.21 in). Base 16, 306 of power storage system 10, 300 may define a width of about 75 cm (about 29.53 in) and a length of about 75 cm (about 29.53 in). Wheels 32 may define a height of about 30 cm (about 11.81 in).

In another non-limiting example, power storage system 10, 300 may define a width of about 75 cm (about 29.53 in), a length of about 120 cm (about 47.24 in), and a height measured from a floor surface of about 125 cm (about 49.21 in). Base 16, 306 of power storage system 10, 300 may define a width of about 75 cm (about 29.53 in) and a length of about 120 cm (about 47.24 in). Wheels 32 may define a height of about 30 cm (about 11.81 in).

In some instances, the footprint of power storage system 10, 300 may relate to the power output and/or the quantity of rechargeable batteries 14. For example, power storage system 10, 300 having one rechargeable battery 14 (see FIG. 2) may define a footprint of base 16, 306 including a width of about 75 cm (about 29.53 in) and a length of about 75 cm (about 29.53 in). Power storage system 10, 300 having two rechargeable batteries 14 (see FIG. 3) may define a footprint of base 16, 306 including a width of about 75 cm (about 29.53 in) and a length of about 120 cm (about 47.24 in). It should be understood, however, that the width and length may be interchangeable, unless otherwise stated or inferred based on the context, without departing from the spirit/scope of this disclosure.

In one example, referring to FIGS. 1, 4, 5, 17, 24, 25B, and 28A, front wall 20, 310 may be one of the main interfaces between power storage system 10, 300 and a user. For example, power storage system 10, 300 may include power panel 102 and display 104. Power panel 102 and display 104 may be in electrical communication with electronic system 100. Power panel 102 may include at least one incoming and/or outgoing electrical receptacle. Display 104 may be configured to display various outputs of and/or related to power storage system 10, 300. For example, display 104 may be configured to display output electrical conditions including, but not limited to, voltage, current, watts, power, battery power remaining, battery recharge time (e.g., estimated and/or actual), ambient temperature, internal temperature of power storage system 10, 300, service messages, warnings, alerts, and the like. Display 104 may be configured to output electrical conditions as a percentage, as a quantity/amount, as a graph, as a table, and the like. Display 104 may be electrically connected to one or more features of power panel 102.

In some instances, display 104 may be removably attached to movable cart 12, 302 (see FIG. 22). Display 104 may include and/or define elements and/or features to directly or indirectly engage with front wall 20, 310 of body 18, 308. Display 104 may also be openable such that display 104 remains directly or indirectly engaged with body 18, 308 but the features/components positioned behind or attached to display 104 are accessible.

Power panel 102 may include at least one incoming and/or outgoing electrical receptacle. Power panel 102 may include a plurality of incoming and/or outgoing electrical receptacles. For example, power panel 102 may include at least one incoming receptacle configured to power and/or charge power storage system 10, 300. At least one incoming receptacle may be either AC or DC. Incoming receptacle may include an electric vehicle (EV) charging connector. Power panel 102 may also include a plurality of outgoing receptacles, including but not limited to, DC receptacle (e.g., 14, VDC, 24 VDC, 48 VDC), AC receptacle, USB-A, USB-C, HDMI, stage pin connector, XLR connector, and related receptacles/connectors depending on specific field of use. Power storage system 10 may be configured to deliver a portion of and/or all of the output power to one or more of the plurality of outgoing receptacles. For example, one of the plurality of outgoing receptacles may receive all of the output power. In another example, the output power may be distributed across a plurality of outgoing receptacles. The distribution of the output power relative to the plurality of outgoing receptacles may be configured based on the equipment connected to the outgoing receptacle(s). The location, quantity and selection of the various receptacles may be selected based on a specific field of use. Referring to the AC receptacles for both incoming and outgoing, the AC receptacle may be selected based on the desired geographical area of use (e.g., United States, United Kingdom, Europe).

Power panel 102 may also include one or more circuit breakers in electrical communication with the various receptacles and electronic system 100. In some instances, at least one circuit breaker may be in electrical communication with at least one receptacle. Power panel 102 may include a main circuit breaker configured to control the main power to and/or from power storage system 10, 300.

Power panel 102 may include an HDMI connector (not shown) and/or an EV charging connector (not shown). As depicted in FIG. 7 in view of FIGS. 2 and 3, electronic system 100 may be in electric communication with power panel 102, display 104, and rechargeable battery 14. Electronic system 100 may include at least one inverter 106, and main control board 108. Inverter 106 is configured to convert AC voltage to DC voltage and/or DC voltage to AC voltage. Inverter 106 may be configured to deliver an output power in pure sinewave. Main control board 108 may dictate which components within electronic system 100 are activated/deactivated, in accordance with a user's direction. Electronic system 100 may include DC module 110 which may be in electrical communication with main control board 108. DC module 110 may be configured to convert variable DC voltage from rechargeable battery 14 into a stable and consistent DC voltage. For example, DC module 110 may be configured to convert about 0% to about 100% capacity of the variable DC voltage from rechargeable battery 14 to a stable and consistent DC voltage of about 48 volts. The variable DC voltage may have a range of about 44 volts to about 58 volts. Electronic system 100 may include inverter board 112 which may be in electrical communication with main control board 108 and inverter 106. Inverter board 112 may communicate between main control board 108 and inverter 106. Electronic system 100 may include a Wi-Fi transmitter and/or a Bluetooth® (registered by The Bluetooth Special Interest Group (SIG)) transmitter so as to send and/or receive information from/to another device (e.g., computer, cellphone). Electronic system 100 may be configured to accommodate a plurality of rechargeable batteries 14. In some cases, electronic system 100 requires minimal modification to accommodate a plurality of rechargeable batteries 14.

For example, FIGS. 8A and 8B illustrate block diagrams of electronic system 100 (FIG. 7) of power storage system 10, 300. FIG. 8A illustrates a power block diagram and FIG. 8B illustrates a signal block diagram of power storage system 10, 300.

Referring to FIG. 8A, once powered, power storage system 10 may operate as illustrated. Rechargeable battery 14 may be in electrical communication with inverter 106 and DC module 110. Inverter 106 may receive DC voltage from rechargeable battery 14 and convert the DC voltage into AC voltage. DC module 110 may receive DC voltage from rechargeable battery 14 and deliver DC voltage to at least one DC voltage receptacle. Inverter 106 may be in electrical communication with inverter board 112, main control board 108, and power panel 102. Thus, power panel 102 may be configured to provide receptacles having AC voltage. DC module 110 may be in electrical communication with main control board 108 and power panel 102. Thus, power panel 102 may be configured to provide receptacles having DC voltage.

Referring to FIG. 8B, signal of power storage system 10, 300 may travel as illustrated and may be displayed on display 104. Rechargeable battery 14 may be in signal communication with main control board 108. Main control board 108 may be in signal communication with DC module 110, inverter board 112, and power panel 102. Inverter board 112 may be in signal communication with inverter 106.

Power storage system 10, 300 may include “smart” charging to charge the rechargeable battery 14. “Smart” charging may refer to management, monitoring and restriction of charging amounts based on a certain input. Electronic system 100 of power storage system 10 may be configured to detect an electrical condition of the charging input. For example, electronic system 100 may detect the inlet voltage that is used to charge the rechargeable batteries 14 and limit the current directed to the rechargeable batteries 14 based on the voltage detected. Doing so may maximize the current draw without overdrawing the system that the power storage system 10, 300 is charging from. For example, if power storage system 10, 300 is capable of drawing up to 30 amps, but the system that the power storage system 10, 300 is charging from has a 20-amp circuit breaker, power storage system 10, 300 can detect the 20-amp circuit breaker and limit the current draw to ensure the circuit breaker does not trip. Power storage system 10, 300 may be configured to receive voltage between about 90 volts to about 260 volts.

In yet another instance, power storage system 10, 300 may be configured to connect to and charge from an electric vehicle (EV) charging station. Power storage system 10, 300 may include an adapter and/or EV charging port to accommodate an EV charging station. Similarly, power storage system 10, 300 may adjust the amount of current directed to the rechargeable batteries 14 based on the inlet voltage from the EV charging station. Electronic system 100 may include circuitry that enables power storage system 10, 300 to charge from an EV charging station. For example, since power storage system 10, 300 is not a vehicle in the traditional sense as EV charging stations are concerned, electronic system 100 may emulate a vehicle to convince the EV charging station to charge power storage system 10, 300.

Power storage system 10, 300 may include a secondary battery that is separate from rechargeable battery 14. The secondary battery (not shown) may operate at least a portion of the electronic system 100. For example, when rechargeable battery 14 is at or near depletion, secondary battery may indicate rechargable battery 14 storage amount to the user (e.g., via display 104). Additionally, secondary battery may operate the Wi-Fi transmitter and/or Bluetooth® (registered by The Bluetooth Special Interest Group (SIG)) transmitter so as to send and/or receive information from/to another device (e.g., computer, cellphone). Power storage system 10, 300 may utilize the secondary battery to provide power to the rechargeable battery 14 (e.g., a trickle charge). Doing so may enable rechargeable battery 14 from shutting down for an extra period of time beyond its normal runtime.

In some embodiments, the secondary battery may operate a heater (not shown) to keep components within power storage system 10, 300 warm. For example, the heater may be external to rechargeable battery 14 to maintain the internal temperature of power storage system 10, 300 at a desired temperature. In other instances, the secondary battery may operate a heater within rechargeable battery 14 so as to ensure rechargeable battery 14 maintains a desired temperature. In one example, sodium-based batteries require the sodium to maintain a certain temperature level before operating and/or charging. Thus, to reduce downtime between charges, for example, the secondary battery may operate a heater within the rechargeable battery 14 to keep the sodium at or near molten levels.

In yet another embodiment, power storage system 10, 300 may include features to keep rechargeable batteries 14 warm without relying on a secondary battery. For example, power storage system 10, 300 may reserve extra power to maintain electronic system 100 and/or operate a heater (internal to and/or external to rechargeable battery 14). In one example, a 9 kWh system may include an additional amount of power in reserve above the 9 kWh, which is the amount provided to a user for use. For example, power storage system 10, 300 may reserve up to about 25% in additional power above the displayed user power (e.g., 9 kWh). In other examples, power storage system 10, 300 may reserve up to about 10% in additional power. In yet another example, power storage system 10, 300 may reserve up to about 5% in additional power. In yet another example, power storage system 10, 300 may reserve a fixed amount regardless of the output power. For example, power storage system 10, 300 may reserve about 1.2 kWh in additional power above the displayed user power (e.g., 9 kWh).

In another embodiment, power storage system 10, 300 may further include power panel 114 and power panel 116. One or more of power panels 102, 114, 116 may be removably attached and/or openable with respect to one or more walls 20, 310, 22, 312, 24, 314, 26, 316 of movable cart 12, 302. In some instances, power panels 114 and 116 may be accessible from back wall 312, which is opposite from power panel 102. Power panels 114 and 116 may be in electrical communication with electronic system 100.

In one embodiment, power panel 114 may include EV charging connector 118, which is in electrical communication with electronic system 100. As depicted in FIG. 26, EV charging handle “A” of an EV charging station may be engaged (e.g., physically connected) with EV charging connector 118. A status indicator (e.g., a light, message) may display when EV charging handle “A” is electrically connected with EV charging connector 118. A status indicator (e.g., a light, message) may display when EV charging handle “A” is physically connected with EV charging connector 118 but is not electrically connected. Electronic system 100 may include the necessary circuitry to receive EV power and safely and efficiently charge at least rechargeable batteries 14. In some instances, electronic system 100 may include the necessary circuitry to receive EV power and safely and efficiently operate power storage system 10, 300.

Power panel 114 may also include E-ink display 120. E-ink display 120 may be an external indicator that detects and/or alerts the user of a condition/event. E-ink display 120 may be an external indicator that detects and/or alerts the user that power storage system 10, 300 may not be moved for a designated amount of time. In a non-limiting example, nonmovement may occur when the system is cooling. E-ink display 120 may be in electrical communication with electronic system 100.

In one example and as depicted in FIG. 27, assembly 400 includes at least two power storage systems 10, 300 in electrical communication therewith. The at least two power storage systems 10, 300 in electrical communication may produce increased capacity based on the sum of the at least two power storage systems 10, 300. For example, if a first power storage system 10, 300 has a capacity of about 9 kWh and a second power storage system 10, 300 has a capacity of about 18 kWh, the total capacity of the two power storage systems 10, 300 is about 27 kWh. As noted herein, each power storage system 10, 300 may have a capacity of about 1 kWh to about 2 MWh.

In some instances, output connector 126 of a first power storage system 10, 300 may be in electrical communication with DC input connector 128 of a second power storage system 10, 300. Output connector 126 and DC input connector 128 may be electrically and physically connected by power cord 130.

Movable cart 302 may further include one or more power panel covers (e.g., electrical receptacle covers) 354, as depicted in FIGS. 19-26. Power panel covers 354 may be hingedly attached to move between a first position (e.g., closed, open) and a second position (e.g., open, closed). As depicted in FIGS. 19-22, power panel covers 354 may be in a first position where power panel covers 354 are in direct or indirect contact with wall 310, 312 such that power panels 102, 114, 116 are substantially covered by power panel covers 354. As depicted in FIGS. 23-25D, power panel covers 354 may move to a second position where power panel covers 354 are open (e.g., away from) relative to wall 310, 312 such that power panels 102, 114, 116 are accessible and uncovered by power panel covers 354. It should be understood, however, that the first position may refer to either closed or open and the second position may refer to either open or closed, without departing from the spirit/scope of this disclosure.

Power storage system 10, 300 may include features/components to direct air through at least a portion of movable cart 12, 302. For example, power storage system 10, 300 may include at least one fan to draw air within and/or push air out from movable cart 12, 302. In some instances, power storage system 10, 300 may include at least one inlet fan configured to draw air within movable cart 12, 302 from the environment external to body 18 and at least one outlet fan configured to push air from within movable cart 12, 302 to the environment external to body 18, 308. In some cases, inlet and outlet fans may be oppositely positioned on either side of electronic system 100 and/or rechargeable battery 14. Inlet and outlet fans may be oppositely positioned on either side of inverter 106. The inlet fans may be configured to direct external air into the inlet side of inverter 106 and outlet fans may be configured to direct internal air towards the exterior of body 18, 308. Doing so may limit the frequency the fans internal to the inverter 106 may have to operate. The quantity of inlet and outlet fans may depend on the desired operating temperature internal to power storage system 10, 300. In some examples, about four (4) inlet fans and about four (4) outlet fans may be utilized. In other examples, about two (2) inlet fans and about two (2) outlet fans may be utilized.

Referring to FIGS. 5 and 9-11, power storage system 10 may include at least two inlet fans 42 and at least two outlet fans 44 positioned opposite to the at least two inlet fans 42. Inlet and outlet fans 42, 44 may be positioned on various outer walls of body 18, depending on orientation of electronic system 100 (e.g., the orientation of inverter 106). For example, in a two rechargeable battery 14 system (FIGS. 5 and 9), inlet fans 42 may be mounted with respect to front wall 20 and outlet fans 44 may be mounted with respect to back wall 22. In another example, in a single rechargeable battery 14 system (FIGS. 10 and 11), inlet fans 42 may be mounted with respect right sidewall 26 and outlet fans 44 may be mounted with respect to left sidewall 24. It should be understood, however, that the orientation of electronic system 100 and/or rechargeable battery 14 may be adjusted in any of the power storage systems 10 and as such, the location of the fans 42, 44 may be changed, without departing from the spirit/scope of this disclosure. Louver 46 may be mounted with respect to fans 42, 44. Louver 46 may protect fans 42, 44 from unwanted debris and/or animals/insects. Louver 46 may include a screen (not shown) to further protect fans 42, 44. In some examples, each fan 42, 44 may include a louver 46 mounted with respect thereto.

In operation, FIGS. 12A and 12B illustrate the air movement across electronic system 100. As noted above, the quantity of inlet fans 42 and outlet fans 44 may depend on a variety of conditions, including the number of batteries, the desired internal operating temperature, the external operating conditions, and combinations thereof. In FIGS. 12A and 12B, power storage system 10 includes two rechargeable batteries 14 and two sets of inlet and outlet fans 42, 44. FIG. 12A illustrates a side view of the air movement across the upper portion of power storage system 10. Direct air flow 48 indicates the air flow across, in this case the plurality of electrical boards/wires of electronic system 100, from either front wall 20 to back wall 22 and/or back wall 22 to front wall 20. The orientation may depend on the layout of the electronic system 100. Turbulent air flow 50 indicates turbulent air flow produced within power storage system 10 as a result of direct air flow 48 from fans 42, 44 contacting the various components and features of power storage system 10. Additionally, and as illustrated in FIG. 12B, direct air flow 48 may pass over and/or through inverter 106, originating from inlet fan 42 towards outlet fan 44. Turbulent air flow 50 may occur as a result of the direct air flow 48 contacting the various components and features of power storage system 10.

In some embodiments, power storage system 10, 300 may be configured to recapture and/or redirect warm air towards rechargeable battery 14 and/or electronic system 100. Warm air may originate from anywhere within power storage system 10, 300 and/or from the environment outside of power storage system 10, 300. In some instances, additional heat may be required to enable electronic system 100 and/or rechargeable battery 14 to operate more efficiently. It is also understood that a result of electrical work is heat. Thus, features/elements within power storage system 10 may redirect and/or recapture the resultant heat and direct the heat, either directly or indirectly, as needed. In one example, internal fans (not shown) may be strategically positioned to redirect heat towards electronic system 100 and/or rechargeable battery 14. In another example, at least one heat sink may be strategically positioned to capture heat. To deliver the heat to electronic system 100 and/or rechargeable battery 14, at least one fan may be positioned to blow air over the heat sink and thus push warmer air in the direction of electronic system 100 and/or rechargeable battery 14. In combination with the above, body 18, 308 of power storage system 10, 300 may further include features/elements to aid in directing the warm air towards electronic system 100 and/or rechargeable battery 14.

In one example, barrier 27 of body 18 may isolate rechargeable battery 14 from the rest of the system to capture heat generated by rechargeable battery 14. Doing so may heat the area surrounding rechargeable battery 14 and thus warm rechargeable battery 14. Barrier 27 may also remove rechargeable battery 14 from direct air flow 48 (see FIGS. 12A and 12B) to ensure that rechargeable battery 14 is not cooled by fans 42, 44.

In one example, sodium-based batteries require the sodium to maintain a certain temperature level before operating and/or charging. Thus, to reduce downtime between charges, for example, warm air may be redirected towards rechargeable battery 14 to keep the sodium at or near molten levels, as discussed above.

Referring to FIGS. 28A-28C, power storage system 300 may include an air inlet 358 in fluid communication with an air outlet 360. Air inlet 358 and air outlet 360 may be positioned relative to bottom surface 362 of base 306 (see FIGS. 28B and 28C). As illustrated, air inlet 358 may be positioned relative to bottom surface 362 of base 306 in proximity to wheels 32. For example, air inlet 358 may be parallel (or nearly parallel) to axis 36 of wheels 32. Air inlet 358 may extend at least partially between wheels 32 in the direction of axis 36. Similarly, air outlet 360 may be positioned relative to bottom surface 362 of base 306 in proximity to wheels 32. For example, air outlet 360 may be parallel (or nearly parallel) to axis 36 of wheels 32. Air outlet 360 may extend at least partially between wheels 32 in the direction of axis 36. Although depicted in proximity to wheels 32 and axis 36, air inlet 358 and/or air outlet 360 may be positioned at other locations relative to bottom surface 362 of base 306 and/or other surfaces of base 306, including different orientations relative to axis 36 of wheels 32.

The arrows in FIG. 28B depict flow path 364 of air from air inlet 358 through body 308 (e.g., across electronic system 100 and rechargeable battery 14) and out air outlet 360. Flow path 364 may be defined, in part, by one or more walls 310, 312, 314, 316, lid 318, and/or base 306. Walls 310, 312, 314, 316, lid 318, and/or base 306 may include features/elements to assist with directing air flow throughout body 308. It should be understood, however, that flow path 364 may be optimized to direct air through body 308 as needed (e.g., to allow air to flow across specific components and/or to avoid specific components). Air inlet 358 may also include one or more filters positioned within the flow path 364 and air outlet may also include one or more filters positioned within the flow path 364. Air inlet 358 and air outlet 360 may each include one or more fans (not shown) to facilitate air movement within power storage system 300. Fans (not shown) may be positioned in close proximity to air inlet 358 and/or air outlet 360 or may be positioned within flow path 364. Air inlet 358 and air outlet 360 may each include a screen, louver, and/or protective cap that allows air flow therethrough but restricts debris, animals, and the like from entering the flow path 364.

In an exemplary embodiment, power storage system 10, 300 may include at least one rechargeable battery 14 and electronic system 100.
