Description

Energy store mounting arrangement

The present disclosure relates to a mounting arrangement for an energy store in the form of one or more battery and, more specifically, although not exclusively, a wall mounting arrangement for displaying the energy store in a prominent manner.

Background of the Invention

A prior art energy storage arrangement is shown in US 2021/013466. As best seen in figure 2, a plurality of batteries 100 are supported on a rack 200. The rack 200 is mounted to a wall “W”. The batteries 100 provide an energy storage arrangement for a building or the like. Such an arrangement may be used to storage excess renewable energy created on site.

The inventor has found numerous problems with prior art systems. Typically, even for a residential property, the batteries may collectively weigh in excess of 100kg. In such properties, the walls are often constructed using bricks covered in plaster or plasterboard etc. Such constructions are rarely configured to support such a load, and thus the batteries may cause structural damage thereto.

In order to remedy this, the batteries may be partially supported by the ground. This limits space on the ground and may require work to be performed on the ground to allow connections thereto. For example, to accommodate electrical cables to the like, cavities may be need to be created in the ground.

Additionally, the racks comprise exposed wiring and/or connectors etc. This may increase the likelihood or damage to the system and/or the risk of electrocution to the user.

Furthermore, prior art systems typically comprise a “functional” aesthetic. For example, batteries, electronics and/or shelving/racking may be exposed. This leads to an undesirable appearance, and thus the battery system may be located in seldom occupied areas (e.g. utility rooms or garages etc.). This may be inconvenient for the user and/or occupy valuable space.

Despite the above problems, the awareness of environmental issues relative to excessive energy consumption is increasing within society. It has been determined that a more practical mounting and/or aesthetic solution for an energy store, e.g. within a home or commercial environment, is needed, for example one that can be visually prominent and does not need to be hidden in a cupboard, closet, garage or other storage space that is hidden from view.

The present invention aims to overcome or ameliorate one or more of the above problems.

A mounting arrangement 2 is shown in figures 1 and 2. The mounting arrangement 2 is configured to aid the mounting of a device 4. In the present embodiment, the device comprises a battery bank, as will be described later. The battery bank comprises a casing or housing 6. The device 4 is mounted to a support structure 8. The support structure 8 is typically planar and/or provided in the vertical direction (e.g. provides a wall). The support structure 8 may provide an exterior or interior portion of a building or the like. It can be appreciated the exact form of the support structure 8 is not pertinent to the invention at hand and the support structure 8 may comprise any suitable form, for example: post; beam; door; ceiling; roof; window; vehicle; container (e.g. ISO container); fencing; or the like.

The mounting arrangement 2 is configured to be mounted/affixed to the support structure 8. The mounting arrangement 2 is mounted to the wall 8 in any suitable fashion (e.g. using fasteners), the exact configuration if which will depend on the wall type (e.g. brick or plasterboard etc.). The mounting arrangement 2 is generally planar with and/or spans across the wall 8. Generally, the mounting arrangement 2 provides a close fit (i.e. engages) the wall 8. The mounting arrangement 2 is thus generally planar. Where the wall 8 is non-flat, the mounting arrangement 2 may be configured to conform to the shape of the wall (e.g. may be curved). Alternatively, the spacing between the mounting arrangement and the wall 8 may vary.

In the present embodiment, the mounting arrangement 2 comprises a framework 10. The framework comprises a plurality of interconnected beams 12. The framework 10 comprises an open structure (i.e. provides gaps 14 between the beams 12). The framework 10 may comprise a grid/lattice or the like. The framework 10/beams 12 may comprises any suitable material, for example: wood; metal; or a polymer.

A gap 16 is provided to receive the device 4. The framework 10 therefore surrounds the device 4. The device 4 engages, is mounted to, or is otherwise affixed to the framework 10. Thus, at least a portion of the weight of the device 4 is supported by the framework. At least a portion of the weight of the device 4 is thereby distributed over the framework. Thus, in turn, the weight of the device 4 is distributed across a greater area of the wall 8 than is the device 4 was mounted to the wall 8. This reduces the chance of damage to the wall 8 (e.g. cracking, warping, bending or subsidence etc. thereof). Additionally or alternatively, this reduces the size and/or depth of fasteners needed to secure to the wall 8, which may be beneficial in historic or rental properties etc.

In some embodiments, the device 4 rests on one or more beams 12, thus transferring weight to the framework 10. Additionally or alternatively, the device is mounted to the framework 10 via one or more fixings, for example: brackets; ties; fasteners etc. In some embodiments, the framework comprises a backboard (e.g. a closed face parallel to wall 8 in use). The gaps between beams 12 thus provide a recess. The device 4 may be mounted to the backboard. In such embodiments, the full weight of the device is supported the mounting arrangement.

In some embodiments, the mounting arrangement 2 may engage the ground 16, thus transferring weight of the mounting arrangement 2/device 4 thereto. For example, the framework 10 may engage the ground 16, and/or a pillar or post etc. may be provided. A majority or all of the weight of the device 4 may be supported by the ground. The weight of the device 4 may be supported by both of the ground and the wall 8. The device 4 may stand on the ground and be secured to the wall, i.e. to ensure the device 4 is fixed in an upright condition once installed.

The device 4 comprises a one or more conduit 18 extending therefrom. The conduit may comprise a conduit for any suitable means, for example, one or more: electrical power; electrical signals; telecommunications; coolant; heat transfer medium (e.g. water); or gases (e.g. cooling air). The conduit may comprise one or more of: an electrical cable; pipe; or fluid duct.

The conduit 18 is contained within the profile of the mounting arrangement 2 (i.e. is contained with the depth of the framework between a side adjacent the wall 8 and a side spaced from the wall 8). The mounting arrangement 2 comprises sufficient depth to accommodate the conduit 18. Typically, the depth of the mounting arrangement will be between 10mm and 300mm. The conduit 18 may pass through the gaps/recess 14.

The conduit 18 may exit the mounting arrangement 2 at an edge thereof. In the embodiment shown in figure 1, the conduit 18 through a lower edge 20 of the framework. The conduit 18 may therefore extend to/through the ground 16. Given the lower edge 20 is adjacent the ground, the conduit 18 only extends a short distance outside the mounting arrangement 2. A cutout 22 is provided in the beam 12 to allow the conduit 18 to pass therethrough. It can be appreciated that any number of conduits 18 may be provided extending in any direction and through any suitable pathway in the mounting system. The conduits 18 may extend out from the mounting arrangement on any side or face thereof (e.g. the conduit 18 may extend into/toward/away from the wall 8). Cutouts/apertures or pass-throughs may be provided in any portions or beams 12 or framework 10 as required. In some embodiments, connectors (e.g. sockets etc.) may be provided on the mounting arrangement 2 to allow connection to an external conduit/connector. #

As shown in figure 2, a panel 24 may be mounted to the framework 10. The facia panel 24 is configured to overlie and/or otherwise enclose the framework 10. The mounting arrangement 2 thus provide an enclosed housing (e.g. the panel 24 provides a facia or the like). This may prevent damage and/or tampering of the conduit 18. This may further improve safety and the conduit 18 and/or any connectors are contained within the mounting arrangement. This may prevent accidental electrocution etc. In some embodiments, the mounting arrangement may comprise fire-proof, fire resistant and/or flame-retardant materials. This may help to prevent or at least retard a fire in the device 4. The facia 24 is removably attached. The facia 24 is thus interchangeable. This may provide access to the device 4 and/or allow replacement of the facia 24.

The facia 24 comprises a cut-out 26 configured to receive the device 4. The cut-out 26 provides a close-fit and/or engages the device 4. This may prevent any tampering of the device 4. The facia 24 comprises a rim/flange 28 configured to overlie the side 30 framework 10. The facia 24 may therefore completely enclose the framework 10. It can be appreciated that in other embodiments, the facia 24 may only cover a portion of the framework 10, for example, in only portions where the conduit 18 extends. The facia 24 is generally rectangular. The facia 24 may therefore provide a frame or the like. The facia completely surrounds the device 4. Again, it can be appreciated, in other embodiments, the facia 24 may only partially surround the device 4.

Referring to figure 3, the mounting arrangement 2 comprises an indicator 32. The indicator 32 may indicate one or more state of the device 4. For example, the indicator 32 may indicate one or more of:

• Power flow into/out of the device;

• A charge level of one or more individual batteries and/or cumulative charge of a plurality batteries;

• Error indicator;

• Mains external power cut;

• Overheating of the device;

• Telecommunications signal level (e.g. GSM or wireless connection level).

In the present embodiment, the indicator 32 comprises an illumination device. The indicator 32 may comprise any suitable indicator, for example, and LED. The indicator 32 is provided proximal the outer perimeter/edge of the mounting arrangement 2. The light emitted from the illumination device thus projects onto the adjacent wall 8. This increase the effective size of the indicator, allowing visual inspection of the device 4 from a greater distance than with the conventional indictors (i.e. as conventional indicators may be difficult to see and/or resolve at a distance). It may further aid those with visual impairments.

The indicator 32 may be provide around the whole or a portion of the perimeter of the mounting arrangement 2. The indicator 32 may be provided as a strip or the like. The strip comprises a plurality of spaced LEDs. The indicator 32 is mounted adjacent an inner side of the rim 28 of the facia 24. The indicator 32 is thus provided about an outer edge of the facia 24. A gap 34 is provided between the rim 28 and the side 30 of the framework 10 to accommodate the indicator 32. Light 36 projecting from the indicator 32 projects onto the wall 8 adjacent the gap 34, thereby “bleeding” from the edge of the facia 24. The indicator 32 thus provides halo/penumbra/aura around the mounting arrangement 2. The size of the gap 34 may be tuned to increase the amount of light bleed from the edge of the facia 24. The indicator 32 may extend partially or fully around the perimeter of the device 4. Such an arrangement ensures the indicator 32 itself it not visible in normal use.

The indicator 32 may be configured to change colours. The colours may change according to one or more state of the device. For example, the colours may change according to a charge level of the battery bank. A first colour may be assigned to a certain range of charge states, a second colour to a second range of charge states, and so on. The indicator may comprise a plurality of different coloured lights and/or RBG light system. Thus, a full colour spectrum may be used. The user may select one or more colour to be provided (i.e. the indicator 32 is configured to allow the user to change the colour thereof) . Additionally or alternatively, the use may select one or more predetermined colour sequence or pattern.

In other embodiments, the indicator 32 may be mounted to the framework 30. As best seen in figure 9, the indicator 32 may extend around the periphery of the device 4. In the present embodiment, the indicator 32 is provided adjacent the back side of the device 4 (i.e. adjacent the wall 8). The indicator is provided in a recessed portion 33 of the device 4. The recessed portion 33 may comprise a angled/truncated corner or the like. In either embodiment, the indicator 32 is configured to project outwardly and/or onto the wall 8. The device 4 may comprise further indicators as required. The device 4 may comprise a display (e.g. a dot-matrix and/or LCD/LED display).

In some embodiment, the indicator 32 comprises an audible indicator. The audible indicator may activate when a state requiring immediate attention of the user is required.

A second embodiment of the mounting arrangement 2 is shown in figure 4. In this embodiment, the facia 24 is mounted directly the wall 8 (i.e. rather than via the framework 10). The facia 24 is mounted to the wall 8 via brackets 38. The brackets 38 may be provided in any suitable position or arrangement. Again, at least a portion of the weight of the device 4 is supported by the facia 24, and thus borne by the brackets 38. The weight of the device 4 is thus distributed over a greater area. The facia 24 may comprises recess/cut-out to accommodate a conduit.

In some embodiments, the facia 24 may be provided beneath the device 4 (i.e. the device is mounted onto the face of the facia 24). The facia 24 may therefore be interposed the framework 10 and the device 4.

A device mounting bracket 40 is shown in figure 5. The mounting bracket 40 allows direct connection of the device 4 to the wall 8. Thus, a portion of the weight of the device 4 is borne by the bracket 40. The bracket 40 may be fixed to the wall 8 may any suitable means. The bracket comprises a two ends 42,44 spaced by a neck portion 46. The bracket 40 is thus I or H-shaped. This helps to distribute the weight of the device 4.

The ends 42,44 comprise respective protrusions 46 configured to be received by corresponding recess 48 on the device. The protrusions 46 are provided at an acuate angle relative to the bracket 40 (i.e. face an upwards direction in use). The device 4 must therefore be lifted upward to facilitate removal from the bracket 40.

Generally, the bracket 40 is configured to be able to support the full weight of the device 4. This allows installation, removal or replacement of the framework 10/facia 24 whilst the device is mounted to the support structure. Once installed the framework 10/facia 24 then support at least some of the weight of the device 24.

In embodiments where the mounting arrangement 2 (i.e. the framework 10 and/or the facia 24) support the full weight, the bracket 40 may not be provided. Alternatively, the bracket 40 may be provided, however, the bracket 40 is configured to merely prevent displacement away from the wall 8 (i.e. horizontally away from the wall 8).

It can be seen that mounting structure 2 increases the effective surface on which the device 4 in mounted on the support structure 8. This reduces the stress on a given area of the support structure 8. The mounting structure 2 may increase the effective surface area by greater than or equal to 20%; preferably by greater than or equal to 50%; preferably by greater than or equal to 75%; preferably, by greater than or equal to 100%. Although the mounting structure 2 increases the effective mounting area, given the mounting structure 2 comprises a lower depth (i.e. the dimension extending away from the support structure), only a marginal increase in volume is provided. This reduces the total volume occupied by the system. The mounting structure 2 may comprise a depth less than or equal to 70% of the device 4; preferably, less than or equal to 60%; preferably, less than or equal to 50%; preferably, less than or equal to 40%;

The device 4 is shown in closer detail in figures 6-9. The device 4 comprises a chassis 50. The chassis 50 is configured to provide structural support and/or rigidity for the device 4. The chassis may comprise a metallic structure (e.g. sheet metal or the like). The chassis may comprise plastic and/or composite material (e.g. carbon fibre).

Panels 52 are attached to the chassis. The panels 52 are provided on respective sides of the chassis 50. The panels 52 and/or the chassis collectively define the housing 6 for the device 4. The panels 52 may be removable/detachable. This allows replacement of the panels 52. For example, a plurality of panels 52 with different colours/textures/patterns may be provided. The device 4 may therefore be modified with the different panel accordingly. The panels 52 may be fixed to the chassis 50 via any suitable means, for example, snap fit and/or fasteners.

Referring back to figure 1 , the device 4 comprises a closure 54. The closure 54 is pivotable/hingedly attached to the device 4 to allow access thereto. The closure 54 may be removably attached (e.g. using snap-fit etc.). The chassis 50 may therefore provide a cabinet/enclosure. The closure 54 may comprise a removable panel 52. The closure panel 52 may attached to the closure 54 using any suitable means. The closure 54 may comprise a recess/aperture to receive the panel 52.

The panels 52 may overlap/abut one another to provide a continuous exterior panel. The panels 52 connected to one another using any suitable means, for example, fasteners, snap fit, or latches etc. The panels 52 may be detachably connected to one another. Each side of the chassis 50 comprises a respective individual (i.e. discrete) panel. In some embodiments, one or more of the panels 52 may enclose two or more sides/faces of the chassis 50. The closure 54 comprise an individual panel 52. The panels are shaped to conform to the shape of the chassis 50 to provide a close fit therewith.

The chassis 50 comprises a partition/shelf 56. This provides support and/or separation of a two or more internal components. As shown in figure 7, the device 4 comprises a plurality of battery units 58. The battery units 58 are spaced/supported on the partition 56. The battery units 58 comprises an electrical energy storage means. Typically, this comprises a plurality of electrochemical cells. The cells may comprises any suitable technology, for example, one or more of: Li-ion; lead acid; Nickel-cadmium etc. In some embodiments, the battery unit 58 comprises a saltwater battery. Providing the cells in battery units 58 allows installation/replacement of a plurality of cell simultaneously. This allows a user to easily remove/add storage capacity without the need for complex wiring arrangements etc. The units 58 may be secured to the chassis 50 using racking or other like supports. In some embodiments, one or more shelf/partition may be left unoccupied to allow for installation of further unit 58 is required. The device 4 is therefore upgradable.

The device 4 comprises an inverter 60. This converts DC power from the batteries to AC for the building supply etc. The inverter 60 may comprise a conventional arrangement. Control circuits 62 (i.e. battery management system); an electrical isolator; a fuse (e.g. RCD); meter (consumption/generation) and/or other ancillary electrical systems may be further provided. In some embodiments, the device 4 may only container battery units 58. In some embodiments, the device 2 comprises only the inverter 60, and optionally the battery management system.

The device 4 comprises a ventilation system. This ensures the battery and/or other components remain at a suitable temperature. Referring back to figure 6, the chassis 50 comprises a one or more vent apertures 64. The vent apertures 64 may extend across a significant length and/or width of the side wall 66 of the chassis 50 (e.g. greater than 50%). The side wall 66 may therefore comprise an open structure or framework. It can be appreciated that the vent apertures 64 may be provided on any/all side of the chassis 50. One or more of the panels 52 comprises vent apertures 68. The panel apertures 68 are smaller than the chassis apertures 64. For example, the panel apertures 68 comprise a grille/grating/mesh. This prevents ingress or dirt/debris.

A filter layer 70 may be provided between the chassis 50 and one or more panels 52. The filter layer 70 may comprise a sheet or the like (i.e. is flat). The filter layer may comprise any suitable filter material (e.g. a foam or like). The filter layer 70 may be interposed the respective apertures 64,68.

The panel apertures 68 generally overlie the chassis apertures 64. This allows greater airflow. In other embodiments, one or more of the apertures 64,68 may be unaligned. This may provide a non-linear (e.g. labyrinth) flow out from the device 4. Airflow may therefore flow at partially parallel to the filter layer 70, increasing the filter properties thereof.

The vents 64,68 extend around a portion of the perimeter of the device. For example, between 5% and 30% of the perimeter. In other embodiments, the vents 64,68 may extend around a majority or completely around the perimeter. For example, greater than or equal 50% of the perimeter; preferably, greater than or equal 80% of the perimeter.

The apertures 64,68 provide a passive cooling system. Vents may be provided on the upper and/or lower surface of the device to aid with convection cooling. In some embodiments, active cooling may be provided. For example, one or more fans may intake/expel air. In some embodiments, the chassis 50 and/or panel 52 may comprise a material configured to radiate and/or reflect heat. For example, the device 4 comprises a mirrored/reflective material. This may also allow the device 4 to blend in with surrounding decorative style and/or provide a mirror.

In some embodiments, the device 4 and/or the mounting arrangement 2 (e.g. the facia 24) comprises a “living wall”. The living wall comprises one or more living plants. The transpire causing a cooling effect (e.g. via evaporative cooling). The plants may further provide shade. The device 4 may comprise a water and/or nutrient system (e.g. hydroponics) to maintain the plants. In other embodiments, the living wall may comprise synthetic plants which may cover vents and/or provide shade. The living wall may further provide improved aesthetics.

The device 4 may direct airflow through/behind the mounting structure 2. This may allow increasing the size of any apertures 64,68 in the housing 6, as the apertures 64,68 are not exposed. This may further aid with cooling of the device 4.

A plurality of devices 4 may be provided. The devices may comprise respective mounting structures 2. The devices 4 may be operatively connected to provide a collective battery system. The devices 4 may be provided in serial or parallel.

In some embodiments, a remote device is configured to operatively connect to the device 4. The remote device may comprise any suitable computing device, for example, inter alia: a mobile (cellular) phone; tablet; laptop; desktop; server etc. The apparatus comprises any suitable communication interface for communication with the remote device. Communication may be provided wirelessly (e.g. Bluetooth (RTM), Wifi, GSM etc.) and/or wired (e.g. ethernet, broadband, fibre optic etc.). Communication between the apparatus and the remote device may be direct (e.g. Bluetooth (RTM), or Wifi) and/or via an intermediatory (e.g. Internet, or remote server). The apparatus may be internet connected (e.g. provides an loT device). Such an arrangement may allow control and/or monitoring of the device. For example, this may allow monitoring of the charge level of the battery.

The indicator 32 may be controllable via the remote device. For example, the remote device may control one or more of: the intensity; colour; lighting pattern/sequence; activation/deactivation of the illumination device. The remote device may be used to receive and/or acknowledge an error or warning message etc.

The facia 24, panels 52, framework 10 and/other aspects of the mounting system 2 may de decorative. For example, the facia 24/panel 52/framework 10 may comprise decorative colouration, shape, texture, finishes or designs (e.g. decals, photographs, artwork, branding, logo etc.). The facia 24/panel 52/framework or portions thereof may be textured/em bossed (e.g. brushed) or untextured (e.g. flat or smooth). The facia 24/panel 52/framework 10 may be multi-coloured or block-coloured. The facia 24/panel 52/framework 10 may be planar or non-planar. The facia 24/panel 52/framework 10 may be removable or replaceable to allow the user to customise the design of the system 2. The system 2 may be provided as a kit of parts comprising a plurality of facias 24, panels 52 and/or frameworks 10. The facia 24/panel 52/framework may comprise a fabric (e.g. as an overlay).

The facia 24/panels 52 may be affixed using one or more releasable connector. The connector may comprise a snap fit and/or interference fit. The connector may comprise a clip or latch etc. The connector may provide magnetic attachment (e.g. a magnet and a magnetic material; and/or a plurality of magnets).

The facia 24/panel 52/framework 10 may comprise any suitable materials, for example, one or more of: metal; polymer; wood; glass; stone/rock; or ceramic etc. The facia 24/panel 52/framework 10 or portions thereof may be transparent and/or translucent. The facia 24/panel 52/framework 10 may be opaque. In some embodiments, the system 2 comprises “digital decoration”. The facia 24/panel 52/framework 10 comprise an electronic display configured to display a decoration. The electronic display allows moving and/or changing of the decoration. The display may extend over a substantial portion of facia 24 and/or the panels 52 (e.g. the front panel). For example, the display may extend over 50%, preferably 80% of the area of the facia 24 and/or the panel 52. The display may comprise any suitable technology (e.g. LCD, LED, OLED etc.).

Decorative elements may be encapsulated/incorporated/suspended on the surface of the facia 24/panel 52/framework 10. For example, one or more decorative element may be encapsulated in epoxy or acrylic on the surface of the facia 24/panel 52/framework 10.

In some embodiments, the facia 24/panel 52/framework 10 may be comprises a decoratable surface. This allows the user to decorate system 2. For example, the surface comprises a finish suitable to provide a substrate to receive paint, ink etc.

The facia 24/panel 52/framework 10 or portions therefore may be illuminated. Illumination devices may be provided accordingly. The illumination devices may project onto/across the facia 24/panel 52/framework 10. The illumination devices may back light the facia 24/panel 52/framework 10. The illumination devices may be embedded or provided on the facia 24/panel 52/framework 10.

The mounting structure distributes the weight of the battery system over a greater area, thereby reducing stress on the wall etc. the system is mounted. This prevents damage thereto. The mounting structure 2 may support at least 10% of the weight of the device 4; preferably, at least 25%; preferably at least 40%.

The framework and/or facia cover any conduits and/or exposed portions of the device 4. This improves safety and reduces the likelihood of damage. The mounting structure may further aid with cooling. The indicator on the device is visible at an increased distanced, thus increasing usability (e.g. for those with restricted eyesight).

The removable panelling allows a flexible and reconfigurable arrangement. As the panelling is mounted to a chassis/framework, it is removable without exposing any of the internal components of the system. The system thus comprising improved safety. Additionally, as the facia is mounted to the framework, when the facia is removed/replaced, the framework remains supporting the device.

Embodiments of the invention as described herein provide an electrical energy store and/or invertor casing in a form that is more conducive to adoption as a fixture or fitting within a ‘lived-in’ area of a home or other premises. The energy store can be customised and altered to suit a user’s decorative taste such that it will not be seen as a purely functional article but can also form an aesthetic part of a room of a house, office or retail space. The invention intends to aid adoption of electrical energy stores such that they can become a desirable/visible device within internal spaces of buildings, e.g. being considered akin to a radiator, bookshelf or similar decorative items.
