Description

[0001] The object of the invention is to develop a modular facade battery storage system for storing electrical power from renewable energy systems, which in particular as a modular component of a facade, which on the one hand as an integrated component of a facade fastening, for example in the form of a hollow chamber profile, covers several tasks, that can be the inclusion of battery cells in the hollow chamber profile, with a carrier profile on which the battery cells are pushed into the hollow chamber profile in a horizontal or vertical direction and at the same time a profile system e.g.as a fall protection device for balcony railings, this balcony railing can be designed as a PV module / panel and generate electrical power, which in turn is temporarily stored directly in the battery storage system integrated in the hollow chamber profile and, as required, is fed into the end user's own power grid and consumed by the end user, this means that the end user can use the electricity produced from his PV system independently and self-sufficiently, while at the same time the public power grid is relieved.

[0002] The modular accommodation of battery cells in a hollow chamber profile according to the invention is characterized by the fact that the cells of the battery storage system can be fully integrated into the external façade, more precisely into the fastening structure of a façade system, in accordance with standards, in a space-saving, safe and invisibly manner.

[0003] The invention is a battery storage system that is integrated into the facade profile for fastening facade elements such as PV modules mounted vertically or horizontally to the facade / railing system or similar power generating systems of renewable energies. Description:

[0004] The invention is an extended, state-of-the-art integrated battery storage system in hollow chamber profiles used for fastening facade elements.

[0005] In the current state of the art, hollow chamber profiles are widely used, particularly because their low weight and the variety of fastening options offer decisive advantages.

[0006] For example, balcony railings in various designs, whether with expanded metal filling, grid variants or glass elements, are widespread; these have previously used hollow chamber profiles as the substructure and / or main fastening to support the structural elements.

[0007] The variant with PV elements as fall protection is a successful extension of the state of the art. This is available in a glass-glass version or as a commercially available PV module as a railing filling for balcony fall protection, also called a balcony power plant.

[0008] The electricity produced by the PV elements is fed directly into the in-house power grid via the end user's standard socket on the balcony or similar, which offers the end user or user of the balcony PV system the advantage of consuming their own electricity.

[0009] As an advanced variant, the state of the art battery / intermediate storage unit is used as a stand-alone unit, also known as a balcony power plant storage unit, which is placed on a balcony or in a building. The advantage of feeding it directly into the power grid is that the energy can be stored when the end user is not using it, e.g., during the day when they are not at home. Later, usually in the evening, they can then access it by using electrical devices. However, this only works as long as there is energy in the battery storage unit. Nevertheless, even with this already available variant, the load on the public power grid is reduced, and power peaks and the main power load are reduced.

[0010] These stand-alone units, also called balcony power plant storage, are usually placed in the space available to the end user, which is usually not sufficient or unsuitable for the permanent placement of a battery storage system.

[0011] General regulations and building permits significantly restrict the use of balcony power plant storage systems; maximum cable lengths and capacity limits, weather-related requirements, fire regulations and other system conditions not listed in detail here severely limit the use of these battery storage options.

[0012] According to the invention, the task will be to expand this variant and to design new buildings or existing buildings in such a way that the end user, the resident of such residential units, is able to generate, store and fully utilize the majority of his electricity consumption in a completely self-sufficient manner by storing electricity generated from renewable energies such as PV power from his balcony railing.

[0013] The solution to the problem is presented by the main claim and by the details and features of the invention, the resulting subclaims, and the following description. Generally speaking, the modular integration of facade battery storage systems for storing electricity from renewable energies in safe, reliable, and flexible designs, such as integration into existing fastening systems for facade cladding, is a solution that creates added value in many areas. It relieves the burden on the public power grid, relieves end consumers by reducing their electricity costs, is a sustainable, environmentally friendly system, and provides scalable modular units that can be designed according to needs.

[0014] The invention is described in more detail below with reference to five figures.

[0015] The Fig. 1 and Fig. 2 shows a "standard" hollow chamber profile (finally assembled) with the dimensions 100mmx50mmx3mm made of steel in the side view (partially transparent). This is characterized by the fact that it can accommodate battery cells in various dimensions and sizes thanks to the modular integrated support profile in the main claim. These can be scaled depending on the application from the range of a cell of 20 watts up to the total achievement of the maximum storage capacity of the power generation system.

[0016] The modular facade battery system is in the Fig. 3 a hollow chamber profile (1) with the dimensions 100mm×50mm×3mm with an integrated internal hollow chamber profile (2) with the dimensions 43mmx10mm with flexible wall thicknesses, adaptable according to manufacturing specifications, for the accommodation of battery cells (3) shown cells with the dimensions: - diameter 38mm height 85mm and a capacity of approx. 20W (per cell), the electrical connections are attached to the head (top) of the cell so that a wiring unit for the connection to the battery positive pole, battery negative pole and battery management / monitoring systems is guaranteed, for the assembly / pre-assembly of the cells in the hollow chamber profile (1) 100mm×50mm×3mm the support profile (2) 43mmx10mm can be pulled out completely from it, the individual cells are therefore easy and cost-effective to access for assembly / pre-assembly or for maintenance.

[0017] The Fig. 1 and Fig. 2 shows a modular facade battery storage system which serves as a support profile in this application for hollow chamber profiles of a balcony railing fall protection system. These are shown with PV modules in glass-glass design, partially transparent, on this modular overall system in the horizontal direction in a total length of 5 m or 2 × 2.5 m.

[0018] The total output of this storage unit is up to approximately 2500W / 2.5kW over the total length of 5m balcony railing PV module system. Fig. The system shown in Figure 2 thus has a state-of-the-art external battery storage design (balcony power plant storage) which must be installed on the end user's balcony area, offering considerable advantages in terms of safety, aesthetics, sustainability, environmental protection and installation application.

[0019] The invention can be prefabricated as a modular construction in new construction projects or in existing buildings, mounted on the facade or facade elements in a time-saving, simple and safe manner by a qualified assembly team and connected to the power grid.

[0020] The solution according to the invention presented here enables battery storage systems from renewable energies to be used safely, easily, sustainably and in an environmentally friendly manner in new or existing facade systems such as balcony safety guards with integrated PV modules. The scalability of storing renewable energy is a special feature. For example, an apartment block with 100 residential units could use an average of only the minimum output of a 5m long balcony railing PV system with the solution according to the invention, an integrated facade battery storage system that feeds 2500W of power per residential unit into the existing power grid, or the end user could use the self-generated electricity to reduce by more than 20% of their electricity requirements that they would otherwise have drawn from the public power grid, thus significantly relieving the burden on the public power grid.

[0021] The solution according to the invention is Fig. 4 is expanded by a modular hollow chamber profile (4) with additional battery cells or hollow chambers (round chamber variant, can be implemented depending on the battery cell shape). Here you can clearly see the flexibility of the invention, that the modular facade battery storage system can be adapted to the storage capacity as needed. More electricity production from the PV modules (e.g. balcony railing PV modules) is to be expected, which is determined depending on the size of the system. More cells are integrated into the facade profile, which thus increases the storage capacity accordingly.

[0022] The Fig. 4 shown profile (4), in the form of a hollow chamber profile with stiffening ribs, round channels and chambers which is designed to accommodate battery management systems called “BMS” and can be manufactured according to the state of the art.

[0023] The four receiving channels (5) for the battery cells arranged one below the other are as in the previous descriptions Fig. 1 and Fig. 2 and Fig. 3 an extension of the storage capacity of the invention, which is thus capable of producing electrical power on a 5m balcony power plant with PV module filling with a capacity of approximately 9.5-10kW.

[0024] This battery storage capacity of approximately 10kW is generally sufficient for normal households with up to 5 people to cover the annual average electricity demand for one day, which means that this inventive improvement in battery storage solutions with all the advantages of the modular facade battery storage system, as is the main claim of this invention, not only represents a far-reaching improvement in safety, sustainability and environmental compatibility, it is also a successful solution to significantly improve the disadvantages of the current state of the art battery storage (stand-alone unit) for self-sufficient storage options that have already been implemented in practice.

[0025] In Fig. The section shown in Figure 4 easily shows the improved possibilities of the modular facade battery storage system for the simple storage of renewable energies in the form of PV power for the expert. This design enables a battery storage system to be integrated easily, cost-effectively, safely, durably, sustainably and in an environmentally friendly manner on a horizontal facade as well as vertically in a facade fastening system. Not only are the battery cells integrated in a design-appropriate manner, but also the cabling and the BMS can be integrated easily and modularly (5)(6). The round channels (6) between the cells are arranged in such a way that they can cool or heat the battery cells as required using different media (water, coolant, inert gas).

[0026] The result: such a system can not only indirectly store energy and cool or heat its integrated cells, but also contribute significantly to the cooling of exterior facades. Depending on the climate zone and time of year, the system can adjust to optimal load conditions in order to keep the efficiency of the battery storage system at a consistently high level, which is unique to date in terms of sustainability, environmental compatibility, efficiency and performance and far exceeds the current state of the art.

[0027] A combination with other innovative facade systems such as greening systems that are mounted horizontally or vertically on external facades can also further improve the system in terms of sustainability. The modular facade battery system can be used in a variety of applications, e.g. in an external gate system Fig. 5 which has no metal grids but PV modules as filling, this generated PV power can be temporarily stored for the electric drive in the modular facade battery storage system (5) for storing electrical power from renewable energies and can be used to open and close the gate system. List of names: Fig. 1: shows a commercially available balcony railing that is 5m long and 1m high with a PV module (photovoltaic) glass-glass filling as fall protection. The fastening system is a commercially available, state-of-the-art hollow profile that fastens the glass-glass PV modules to the building structure. The inventive solution from the main claim, the modular facade battery storage system, in this example, is firmly connected below the PV module balcony railing described above, so that this unit can be modularly and cost-effectively prefabricated and installed on a building shell by specialist personnel. Fig. 2: shows the facade battery storage system technology described in Fig:1 from the main claim, the standard hollow profile 100mmx50mmx3mm (shown transparent) is hereby enabled by the facade battery storage system hollow profile 43mm×10mm with the individual battery cells, to store the PV power produced from the glass-glass modules directly in the mounting profile, this solution becomes the modular facade battery storage system described in the main claim. Fig. 3 shows the commercially available hollow chamber profile 100mmx50mmx3mm with the inventive solution for facade building battery storage directly in the fastening profile, through the modular facade battery storage system solution from the main claim, with internal extendable hollow profile (here designed in 43mmx10mm) which can accommodate the battery cells scalably depending on the size, the solution includes the modular cost-optimized production and maintenance as a complete system, the integrated battery storage in the facade fastening system, the multitude of application cases (facade greening systems, gate systems) as described in the subclaims from the main claim. Fig. 4 shows the modular expandability of the invention of a facade battery storage system, the hollow chamber profile (4) in this example of a possible design accommodates battery cells in four profile hollow chambers arranged for this purpose along the entire length of the balcony railing for PV modules, these store the produced electricity directly in the fastening profile, the entire technology can be as in Fig. 4 can be seen in further cavity pockets designed for this purpose, the battery management system is thus fully integrated centrally into the facade fastening system, furthermore cooling and heating ducts (6) are integrated in this design, this variant defined in the main claim enables demand-based air conditioning of the facade battery storage system for the provision of optimal operating conditions, with the positive side effect of having a favorable influence on the climate of the entire external facade. Fig.5 shows an example of the inventive solution of the modular facade battery storage system for storing electrical power from renewable energies, an external gate system with PV module filling that can store the produced PV power directly in the integrated hollow chamber profile, designed so called facade battery storage system, this can be used simply, cost-effectively, modularly, to close and open the external gate system directly, other nearby consumers (lighting system, security system, battery charging unit) can also cover their power needs with it. 1 hollow chamber profile 100mm×50mm×3mm×2500mm->scalable, depending on the system length. 2 hollow chamber profiles 43mm×10mm×2500mm->scalable, depending on the system length. 3 battery cells D=38mmx85mm scalable depending on the storage version. 4 hollow chamber profiles 100mm×200mm×3mm×2500mm, per system length. 5 receiving chambers in hollow chamber profiles (can be designed for specific applications) 6.
