[0001] DESCRIPTION

[0002] ’’ SYSTEM FOR CONDITIONING A BATTERY PACK AND A POWER INVERTER AND SYSTEM FOR SUPPLYING POWER TO A TELECOMMUNICATIONS SYSTEM"

[0003] TECHNICAL FIELD OF THE INVENTION

[0004] The present invention refers to a system for conditioning a set of batteries and a power inverter for supplying power to a telecommunications system including a telecommunications tower, for example , a mobile telephone tower .

[0005] PREVIOUS TECHNIQUE AND PROBLEMS OF THE PREVIOUS TECHNIQUE

[0006] A battery pack for a telecoms tower, also known as a backup power system or uninterruptible power supply, is designed to provide electrical power to the telephone tower in the event of a power outage or when the main power source , namely the conventional electricity distribution network, is unavailable . The battery pack ensures that the tower remains operational and connected to the telecoms network even during periods of power interruption .

[0007] Battery cabins , which act as a backup power supply for telecommunications systems , must have weatherproof construction features . Cabins are usually built with weather-resistant materials , such as galvanised steel or aluminium, in order to protect the equipment stored inside the cabin from rain, wind, dust and other environmental elements . Cabins must have a solid structure , with sealed doors and windows to prevent water ingress and maintain a controlled internal environment . Considering the operating conditions of the equipment housed in the cabins housing the backup batteries and power inverters , it is necessary to adopt safety measures for fire suppression, such as equipping the cabin with fire suppression systems , like fire extinguishers or automatic fire suppression systems . These systems help reduce the risk of fire in the event of a battery mal function or other unforeseen circumstances .

[0008] In the context of cabins conditioning a power inverter and batteries , there is a need to develop a system for conditioning this necessary equipment with high levels of fire suppression, without having to resort to auxiliary fire- fighting devices . In this way, there is a need to develop a conditioning system for a set of batteries and a power inverter configured to supply power to a telecommunications system that incorporates preventive means of fire suppression, particularly preventive means based on the very construction materials of the conditioning cabin .

[0009] In addition, the conditioning cabins of a power inverter and batteries need to have constructive aspects that also provide adequate control of their internal temperature , in order to maintain proper operation and the ef ficiency designed for the internal components , such as the batteries . Controlling the internal temperature of the conditioning cabin is particularly important when using VRLA (valve-regulated lead-acid battery) or lithium batteries .

[0010] PROBLEM SOLUTION

[0011] The present invention solves the problems of the prior art through the development of a system for conditioning a set of batteries and a power inverter configured for supplying power to a telecommunications system, in which a chamber for conditioning a set of batteries and a power inverter is made of a composite material resulting from the hydration of a hydraulic binder comprised in a cementitious composition, which also includes a plurality of fibres based on cellulose or keratin and an adj uvant , in which said composite material has fireproof characteristics .

[0012] The present invention also includes the incorporation of a water tank for conditioning and cooling the batteries during their operation and a water circulation subsystem, which collects water from the tank and directs part of the water to the walls made of the aforementioned composite material and returns the remaining portion of the circulation water to the water tank .

[0013] The composite material from which the walls of the conditioning chamber are made has an additional functionality to that related to the fire resistance characteristics , namely that the composite material absorbs part of the water made available by the water circulation subsystem in order to help cool the interior of the conditioning cabin by evaporative cooling .

[0014] ADVANTAGES OF THE INVENTION

[0015] The conditioning system for a set of batteries and a power inverter according to the invention is configured to of fer protection against external climatic conditions and guarantee adequate ventilation for cooling the devices installed inside .

[0016] In the preferred embodiments using a cementitious composition, after curing, results in a composite material that allows high resistance to cracking, due to the nature and pattern of the fibres , which, instead of cracking, undergo plastic deformation in the physically af fected area, without spreading . In addition, the composite material formed when curing the cementitious composition is resistant to high and low temperatures , fire and water, and has density values similar to the density of wood .

[0017] The conditioning cabin is weather-resistant , protecting the equipment inside from rain, wind, dust and other environmental elements .

[0018] In the preferred designs that use a cementitious composition, the physical structure of the composite material is porous , providing thermal insulation and acting as a barrier to the propagation of infrared radiation . In addition, together with the cement that forms part of the composite material , it becomes fireproof , sealing the fibres with a layer of crystals present in the cement , which prevents them from burning . The composite material has the properties highlighted above and has other properties with values similar to those of wood, namely density, mechanical resistance and thermal insulation properties .

[0019] The composite material made of a hydraulic binder and a plurality of cellulose or keratin-based fibres also has physical properties that contribute to thermal cooling by evaporation when the walls of the conditioning chamber are moistened, which in combination with the action of the water circulation pipe , increase the heat trans fer rates by evaporative cooling inside the conditioning chamber .

[0020] The water tank has a triple function, namely water storage , battery storage and as a temperature conditioning element for the batteries . BRIEF DESCRIPTION OF THE PICTURES

[0029] The cementitious composition, particularly favoured by the invention and described in the previous paragraph, used to manufacture the second set of side walls and the top plate ( 10 ) provides insulation to regulate internal temperatures and protect the equipment from extreme heat or cold . The insulation helps maintain a stable environment and prevents temperature fluctuations that could af fect the performance and useful li fe of the set of batteries ( 18 ) . In addition, thi s cementitious composition has fire-retardant properties .

[0030] Preferably, the hydraulic binder is at least one of the group consisting of cement or gypsum . Even more preferably, the hydraulic binder i s cement , namely ordinary Portland cement , which mainly comprises clinker and small amounts of calcium sulphate ; composite Portland cement containing additions of materials such as blast furnace slag, natural poz zolans or fly ash, where these additions give the cement speci fic characteristics , such as greater resistance to sulphates or greater durability in aggressive environments ; poz zolanic Portland cement which contains a high quantity of natural poz zolans , such as volcanic ash, which react with calcium hydroxide during hydration, increasing strength and durability; blast furnace Portland cement which contains blast furnace slag, a by-product of iron production, which gives the concrete greater strength and durability; or high early strength Portland cement which has a faster hardening rate , making it ideal for applications requiring demoulding or rapid release .

[0034] In the preferred forms of production, the cellulose or keratin-based fibres are crushed or ground before mixing with the hydraulic binder .

[0035] Preferably, the cotton fibres used to make the food composition have an average length of less than 5 mm, even more preferably less than 2 mm . Preferably, the cotton fibres are subj ected to a prior degreasing and bleaching process , for exemple , using sodium hypochlorite and / or hydrogen peroxide .

[0036] Preferably, the crushed hemp fibres for the manufacture of the food composition comprise agglomerates of crushed fibres with average longitudinal particle si zes in the range of 0 , 5 to 1 cm and average transverse particle si zes in the range of 0 , 1 to 0 , 3 cm .

[0037] In designs where the second set of side walls comprises at least one wall made from a cementitious composition made from a hydraulic binder and a plurality of cellulose or keratin-based fibres , the natural fibres exposed to the weather are naturally broken down in a slow process , The formation of this relatively thin plant layer on the outside of the second set of side walls contributes to the technical ef fect of forming an additional layer of thermal insulation, as illustrated in figure 5.

[0038] In the preferred embodiments , the adj uvant used to prepare the composite material is at least one of the group consisting of calcium silicate , calcium chloride , alkylene- based accelerators, sugar alcohols, aluminium sulphate, formic acid, silanes, siloxanes, fatty acid esters, esters of polyoxyethylene, acrylic resins, styrene acrylic resins, polyvinyl acetate, sucrose, sugar and sodium tetraborate. Even more preferably, the adjuvant is, at least, one of the group consisting of polyvinyl acetate, sucrose, sugar and sodium tetraborate. Sodium tetraborate is an adjuvant that acts as an insecticide. Preferably, the concentration of the hydraulic binder in the cementitious composition is in the range of 70 to 97% by mass in relation to the mass of the cementitious composition, even more preferably 85 to 95%.

[0039] In other preferred embodiments, the concentration of the cellulose or keratin-based fibres is in the range of 3 to 30% by mass in relation to the mass of the hydraulic binder, even more preferably 10 to 15%.

In other applications, the adjuvant comprises 5 to 35% by weight of polyvinyl acetate, preferably 15 to 20%. In other forms, the adjuvant comprises 1 to 20% by mass of sodium tetraborate, preferably 5 to 15%.

[0042] The cementitious composition also has physical properties that contribute to thermal cooling by evaporation when the second set of side walls and the top plate (10) are moistened, which in combination with the action of the water circulation pipe (21) increase the heat transfer rates by evaporative cooling inside the conditioning chamber (25) . The pumped water is conducted through the water circulation pipe (21) , which is distributed at various points in the walls in order to even out the flow of water throughout, returning the surplus to the water tank (13) .

[0043] Preferably, the water circulation pipe (21) has a plurality of holes arranged at the points of contact between the water circulation pipe (21) and the second set of side walls. Even more preferably, the water circulation pipe (21) also has a plurality of holes arranged at the contact points between the water circulation pipe (21) and the top plate (10) . In this way, a fraction of the water pumped and circulating in the water circulation pipe (21) flows in a quasi-laminar regime into the second set of side walls through said holes, and this water contributes to the evaporative cooling provided by the cementitious composition. Preferably, the holes in the water circulation pipe have diameters in the range of 0,1 mm to 2 mm.

[0044] The water tank (13) has a triple function, namely water storage, battery storage and as a temperature conditioning element for the batteries.

[0045] Preferably, the water tank (13) is buried or earthed, the plane intersecting the upper face of said water tank (13) being arranged in the plane of the ground or below the plane of the ground in a range from 1 cm to 100 cm, even more preferably in a range from 10 cm to 20 cm. This method is particularly preferred when the conditioning system is located in areas with a tropical or equatorial climate.

[0046] The water circulation system comprises the water circulation pipe (21) and the pump (20) , which is preferably a low-voltage DC submersible pump with a consumption of 15\20 watts, prepared to work 24 hours a day and operated by a level pressure switch (24) , so that it is operational whenever there is water available in the water tank ( 13 ) . Preferably, the pump ( 20 ) is configured to work submerged and continuously, has ceramic bearings and its suction is protected by a filter, for example , a stainless steel mesh, and is controlled by the level pressure switch ( 24 ) .

[0047] The characteristics of the composite material in terms of evaporative cooling and its properties in terms of adherence to its surface mean that the outer faces of the walls of the conditioning chamber ( 25 ) are favourable as a support for plant growth, as illustrated in Figure 5 , where the plants also end up contributing to the thermal insulation of the conditioning cabin .

[0048] The water circulation pipe ( 21 ) has a surface with a plurality of perforations , which can have multiple orientations . These perforations promote direct dripping into the water tank ( 13 ) and also promote a flow of water to the internal surfaces of the second set of side walls . In this way, the second set of sidewalls remains moist , contributing to the transport of heat from the wall to the base and from the base to the ground (via water or the circulation system) . The second set of side walls absorb water from the system, as well as water from rain, dew or other natural elements , either by direct action ( rain or direct contact ) or by indirect action .

[0049] In the preferred embodiments at least a first waterproofing screen ( 26 ) and a second waterproofing screen ( 27 ) are arranged on the internal surfaces of the conditioning chamber ( 25 ) , said waterproofing screens acting as a protective barrier against water entering the electrical / electronic components of the devices packaged inside the conditioning chamber ( 25 ) . Even more preferably, the first waterproofing screen ( 26 ) and the second waterproofing screen ( 27 ) are arranged on the inside surfaces of at least one of the plates selected from the group comprising the third side plate (6) , the fourth side plate (7) , the second back plate (8) , the second front plate (9) and the top plate (10) .

[0051] As illustrated in figures 7 and 8, a set of first waterproofing screens (26) is arranged inside the conditioning chamber (25) , covering substantially the entire internal area of the walls of said chamber, to prevent water from reaching the upper portions of the batteries and / or the other electrical / electronic equipment arranged inside the conditioning chamber (25) .

[0052] As illustrated in figure 9, a first waterproofing screen (26) is laid over the inner side wall of the conditioning chamber (25) and a second waterproofing screen (27) is laid over the inner front wall of the conditioning chamber (25) , providing a protective barrier against water entering the electrical / electronic equipment inside the conditioning chamber (25) . Preferably, the first waterproofing screen (26) and the second waterproofing screen (27) are supported by a cable forming an inverted V- shaped cover, and the supporting cable can be fixed to one of the side walls of the conditioning chamber (25) .

[0053] In the particularly preferred embodiments, as illustrated in Figures 1 and 2, the first set of side walls in the conditioning system comprise: a first side plate (2) ; and a second side plate (3) ; and a first back plate (4) ; and where, a first front plate (5) ; and where, the first side plate (2) and the second side plate (3) are parallel to each other and are connected orthogonally to the base plate (1) ; and where, the first back plate (4) and the first front plate (5) are parallel to each other and are connected orthogonally to the base plate (1) ; and where, the first side plate (2) and the second side plate (3) are simultaneously connected orthogonally to the first back plate (4) and the first front plate (5) ; and wherein the second set of side walls comprises: a third side plate (6) ; and a fourth side plate (7) ; and a second back plate (8) ; and a second front plate (9) ; and where, the third side plate (6) and the fourth side plate (7) are parallel to each other and are connected orthogonally to the top plate (10) ; and where, the second back plate (8) and the second front plate (9) are parallel to each other and are connected orthogonally to the top plate (10) ; and where, the third side plate (6) and the fourth side plate (7) are simultaneously connected orthogonally to the second back plate (8) and the second front plate (9) ; and where, the edges of the third side plate (6) and the fourth side plate (7) are connected adjacently to the edges of the first side plate (2) and the second side plate (3) ; and where, the edges of the second back plate (8) and the second front plate (9) are connected adjacently to the edges of the first back plate (4) and the first front plate (5) ; and where, the water tank (13) is delimited by the base plate (1) , the first side plate (2) , the second side plate (3) , the first back plate (4) and the first front plate (5) ; and where, the conditioning chamber (25) is delimited by the top plate (10) , the third side plate (6) , the fourth side plate (7) , the second back plate (8) and the second front plate (9) ; and where, the power inverter (19) is connected to at least one wall that borders the conditioning chamber (25) ; and where, at least one door (11) is arranged in at least one wall that delimits the conditioning chamber (25) .

[0054] In the designs illustrated in Figures 1 and 2, the third side plate (6) , the fourth side plate (7) , the second back plate (8) , the second front plate (9) and the top plate (10) are made from the composite material resulting from the hardening of the cementitious composition.

[0055] Preferably, the base plate (1) and the first set of side walls are made of masonry, and this type of construction is particularly favoured for ways of using the conditioning system for a battery pack and a power inverter, where the water tank (13) is arranged in a below-ground quota. As illustrated in Figures 1 and 2, the underside of the base plate (1) includes a plurality of transversely arranged projections, which allow for the attachment of forklift arms to facilitate the transport of the conditioning system for a battery pack and a power inverter to its installation site.

[0056] As illustrated in Figures 1 and 2, the conditioning cabin comprises at least one hole (12) arranged through at least one wall of the second set of side walls, which allow air to flow through the conditioning cabin and consequently contribute to higher heat transfer rates by evaporative cooling .

[0057] Adequate ventilation is very important for cooling the set of batteries (18) . The conditioning cabin preferably includes a plurality of ventilation holes (12) , where the holes (12) are arranged in the second back plate (8) and the second front plate (9) . The ventilation holes (12) facilitate the flow of fresh air and dissipate the heat generated by the batteries (18) and the power inverter (19) , helping to prevent overheating and to ensure optimum performance and longevity of the equipment.

[0058] Preferably, at least one door (11) is arranged in the second front plate (9) to allow the user to access the interior of the conditioning cabin in order to install devices or carry out maintenance on any equipment installed inside. Each door (11) can include a locking subsystem configured to be opened only by authorised personnel.

[0059] Preferably, as illustrated in Figures 1 and 2, at least one mesh net (14) is arranged inside the conditioning chamber (25) to prevent insects from reaching the equipment installed inside the conditioning chamber (25) . The mesh net (14) can be installed inside the conditioning cabin, being attached, for example, to the second front plate (9) and downstream of the holes (12) in the said plate.

[0060] As shown in figure 3, a blower (22) can be arranged inside the conditioning chamber (25) and installed in an area close to the power inverter (19) to help cool it down.

[0061] The conditioning cabin can incorporate temperature sensors to continuously monitor the internal temperature. If the temperature exceeds predetermined limits, the control and monitoring subsystem (23) can trigger alarms or activate additional cooling mechanisms to maintain a safe operating range. The conditioning cabin can also include sensory subsystems based on humidity, water level, movement and intrusion detection and lighting sensors.

[0062] In some cases, especially in regions with high ambient temperatures, additional cooling methods can be employed, by means of blowers (22) , heat exchangers or air- conditioning units to provide active cooling and ensure that the set of batteries (18) operates within its optimum temperature range.

[0063] The conditioning system also has an additional component that contributes to the cooling capacity, namely the water tank (13) , which uses the high heat capacity of water to stabilise the interior temperature of the conditioning cabin.

[0064] Preferably, the second set of side walls are inclined in such a way as to allow water to flow towards the inside of the conditioning chamber (25) , including flow from the outside of said conditioning chamber (25) to the inside, taking into account the porosity of the materials used to make the second set of side walls or their holes (12) .

[0065] The present invention relates, in a second aspect, as illustrated in Figure 4, to a system for supplying power to a telecommunications system comprising:

[0066] The conditioning system as defined in any of the preceding claims; and a primary power-generating system (15) ; and a secondary power-generating system (16) ; and a telecommunications system (17) ; and wherein, the power inverter (19) is electrically connected to the set of batteries (18) , the primary power-generating system (15) , the secondary power-generating system (16) and the telecommunications system (17) .

[0067] Preferably, the power inverter (19) is additionally electrically connected to the blower (22) , to the level pressure switch (24) , which acts to activate the pump (20) and to a control and monitoring subsystem (23) of the set of batteries (18) .

[0068] The set of batteries (18) for a telecommunications system (17) , which includes a telecommunications tower, acts as a backup power subsystem or an uninterruptible power supply and is designed to provide electrical power to the telecommunications tower in the event of a power failure or when the primary energy-generating system (15) is unavailable. The set of batteries (18) ensures that the tower remains operational and connected to the telecommunications network even during periods of power interruption.

[0069] The primary energy-generating system (15) for a telecommunications tower is usually the electricity grid or a local power source. This power is used to operate the tower's equipment, including radios, antennas and other communication devices.

[0070] The set of batteries (18) comprises a bank of batteries (18) designed to store electrical power. These batteries (18) are charged when the primary power generating system (15) is available and the telecommunications tower is operating normally. The process of charging the batteries (18) is normally controlled by a battery charger, which ensures that the batteries (18) are charged to their optimum capacity .

[0071] The set of batteries (18) is equipped with a control and monitoring subsystem (23) to continuously monitor the state of the batteries (18) and the system as a whole, which includes monitoring battery voltage, current, temperature and other relevant parameters to ensure that the batteries (18) are operating within safe limits.

[0072] The control and monitoring subsystem (23) can communicate with a communication network, for example, a communication network, which includes at least one network selected from the group consisting of a public network, an interconnected set of public and / or private networks, such as the Internet, and a private network. In addition, communication can be realised via wires or via wireless means of communication, for example wireless means of communication, ethernet, Bluetooth and SIM.

[0073] In the event of a power failure or when the primary power-generating system (15) becomes unavailable, the system supplying power to a telecommunications system automatically switches from the main power source to battery power through the actions of the control and monitoring subsystem (23) , which detects the loss of power and starts supplying the power stored in the batteries (18) in a matter of seconds.

[0074] The power inverter (19) converts the direct current (DC) stored in the batteries (18) into the alternating current (AC) needed for the telecoms tower equipment. The power inverter (19) transforms the DC power from the batteries into a stable AC power output that corresponds to the tower's requirements.

[0075] The AC power output from the power inverter (19) is then distributed to the tower's equipment, including radios, antennas and other communication devices. The set of batteries (18) ensures a consistent and reliable power supply, allowing the tower to function normally even during a power outage.

[0076] When the tower is running on battery (18) power, the batteries gradually discharge their stored power. The control and monitoring subsystem (23) continuously monitors the voltage and capacity of the batteries (18) to ensure that the tower's power needs are met and that the batteries (18) are not completely discharged. As soon as the primary power generating system (15) is restored, the set of batteries (18) returns to charging mode to replenish its power .

[0077] The secondary power-generating system (16) can comprise at least one power source, for example photovoltaic panels, fuel generators, wind generators, fuel cells and microturbines .

[0078] In preferred embodiments, the conditioning system comprises at least one battery (18) selected from the group consisting of a VRLA-type lead battery (valve-regulated lead-acid battery) , a lithium battery, an AGM-type battery (Absorbent Glass Mat) , or a gel battery. Even more preferably, the VRLA-type lead battery is a high-temperature deep-cycle battery. Preferably, the battery (18) has a minimum power of 40kwh. Gel batteries are particularly suitable when high resistance to high temperatures is required .

[0079] Example

[0080] Composite side walls were prepared from a cementitious composition comprising cement, cotton fibres, polyvinyl acetate, sucrose, sugar and sodium tetraborate, obtaining a composite material.

[0081] In a thermal conductivity test carried out by LNEC - "Laboratorio Nacional de Engenharia Civil", in accordance with European standard EN 12667 : 2001-en, the composite material in the example obtained a thermal insulation rating of 0,143 W / m°C, corresponding substantially to the same rating as wood, but with better insulation capacity. However, unlike wood, the composite material is not flammable and does not deform when exposed to high temperatures / heat .

[0082] In comparative terms, ETICS material is known to have a thermal conductivity of around 0,03 W / m°C, hemp blocks 0,4 W / m°C, plastering mortar 0,3 to 1,0 W / m°C and concrete 1,5 to 2 W / m°C .

[0083] The composite material was subjected to a first test, which included exposure to a direct flame with temperatures above 300 degrees Celsius and a 60-minute exposure to the 4 cm thick barrier, without any significant changes to its structure.

[0084] Then, as an active form of prevention, the same test was carried out with the composite material with a thickness of 4 cm wetted and subsequently exposed to direct flame at temperatures above 1200 degrees Celsius for a period of 1 minute. It was found that the exposed surface is not af fected, nor does it show a temperature di f ferential from one side to the other . Thus , the face exposed to the flames is practically intact and the temperature of the face exposed to the flames , after 5 seconds of the flames ceasing, goes from 1200 degrees to less than 60 degrees Celsius .

[0085] The reaction to fire classi fication for construction products , including products incorporated into construction elements , is defined in standard EN 13501 - 1 : 2018 . Also known as "Euroclasses" , this standard provides for seven classes of reaction to f ire for materials (Al , A2 , B, C, D, E and F) , with Al being the class to which materials that contribute the least to the development of fire in the environment belong and F being the class with the greatest contribution .
