Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of energy storage, in particular to an electrical cabin and an energy storage device. BACKGROUND

[0002] The energy storage device is a device for storing electrical energy, thermal energy or mechanical energy, which can release the stored energy when needed to achieve energy balance and regulation. Its core function is to solve the problem of energy supply and demand imbalance, improve energy utilization efficiency, and enhance the stability of the power grid. The electrical cabin is an important part of the energy storage device. The electrical cabin in the energy storage device usually includes power conversion systems, liquid cooling units, controllers, circuit breakers, terminal blocks and other main functional devices, which are used to control and manage the charging and discharging process of the energy storage device. These devices will generate a large amount of heat during operation, so an efficient heat dissipation system is needed to maintain the normal working temperature to ensure the performance and service life of the electrical cabin.

[0003] In related technologies, the heat dissipation mode of the electrical cabin is air cooling. However, there is a lack of effective air flow organization optimization between the air inlet side and the air outlet side of the electrical cabin, which causes the hot air generated by the functional devices in the electrical cabin to circulate in the gap between the devices and may be sucked into the air inlet side of the electrical cabin again, thereby causing the temperature in the electrical cabin to rise and affecting the heat dissipation efficiency of the device. In addition, when the device is running at high load, the heat accumulation problem is particularly serious, which easily leads to overheating damage of the device and shortens its service life.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] In the following description, when referring to the accompanying drawings, the same numbers in different drawings denote the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0028] In related technologies, the electrical compartment is typically cooled by air. However, the lack of effective airflow optimization between the air intake and exhaust sides of the electrical compartment causes hot air generated by the functional components to circulate in the gaps between the components and may be drawn back into the air intake side of the electrical compartment, leading to increased temperature and reduced heat dissipation efficiency. Furthermore, the problem of heat accumulation is particularly pronounced when the equipment is operating under high loads, easily causing overheating damage and shortening its lifespan.

[0029] To improve the heat dissipation efficiency and service life of the electrical compartment, this application provides an electrical compartment, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the priority of the embodiments.

[0030] Please see Figures 1-3 , Figure 1 This is a schematic diagram of the first structure of the electrical compartment provided in the embodiments of this application. Figure 2 This is a schematic diagram of a second structure of the electrical compartment provided in an embodiment of this application. Figure 3 This is a schematic diagram of the third structure of the electrical compartment provided in the embodiments of this application. Figure 3 This is a schematic diagram of a third structure of the electrical compartment provided in the embodiments of this application. The electrical compartment 100 may include a housing 110, a heat-generating device 120, a wind baffle 130, and a heat dissipation assembly 140.

[0031] Specifically, in the heat dissipation design of the electrical compartment, the enclosure 110 is the core structure of the electrical compartment 100, and its design directly affects the heat dissipation efficiency and equipment performance of the electrical compartment 100. The enclosure 110 includes an air inlet 111 and an air outlet 112, and the air inlet 111 and the air outlet 112 are arranged opposite to each other, which helps to optimize airflow organization and form an efficient heat dissipation channel.

[0032] In some embodiments, the heat-generating device 120 is the main heat-generating device within the electrical compartment 110. The heat-generating device 120 may include devices such as a power conversion system, a liquid cooling unit, a controller, a circuit breaker, a terminal block, and a converter. The heat-generating device 120 undertakes core functions such as energy conversion, transmission, and control in the energy storage device, and also generates a large amount of heat due to power loss during operation.

[0033] Specifically, the heating element 120 is installed inside the enclosure 110 of the electrical compartment. The air inlet 121 of the heating element 120 faces the air inlet 111 of the enclosure 110, and the heat dissipation vent 122 of the heating element 120 faces the air outlet 112 of the enclosure 110. This ensures that external air can directly enter the heating element 120 from the air inlet 111 of the enclosure 110 through the air inlet 121 of the heating element 120, and be discharged outside the heating element 120 through the heat dissipation vent 122 of the heating element 120. Subsequently, some of the heat generated by the heating element 120 is discharged outside the enclosure 110 through the air outlet 112 of the enclosure 110.

[0034] In some embodiments, the baffle plate 130 is disposed between the heat dissipation port 122 and the air inlet 121. Specifically, the baffle plate 130 may be disposed on the same plane as the cover plate where the air inlet 121 of the heat-generating device 120 is located. The baffle plate 130 can divide the housing 110 into two chambers, one chamber being provided with an air inlet 111 and the other chamber being provided with an air outlet 112.

[0035] It should be noted that the purpose of setting the baffle 130 is to cover the gaps between adjacent heat-generating devices 120 and the gaps between the heat-generating devices 120 and the side wall of the housing 110, thereby preventing the hot air discharged from the heat dissipation port 122 of the heat-generating devices 120 from circulating in the gaps between the heat-generating devices 120 or in the housing 110, so as to prevent the hot air from being re-inhaled into the air inlet 111 and the air intake 121. That is, the baffle 130 is used to prevent the hot air generated by the heat dissipation port 122 from flowing back to the air intake 121, thereby preventing the temperature inside the electrical compartment 100 from rising, optimizing the airflow organization inside the electrical compartment 100, ensuring the separation of hot and cold air inside the electrical compartment 100, and improving the heat dissipation efficiency of the electrical compartment 100.

[0036] Specifically, by setting a baffle plate 130 inside the housing 110, external air is ensured to enter the housing 110 from the air inlet 111, then enter the device from the air inlet 121 of the heating device 120, and is discharged sequentially from the heat dissipation port 122 and the air outlet 112, forming a single-phase airflow channel. The heat generated by the heat dissipation port 122 cannot flow back to the air inlet 121 and the air outlet 111 due to the presence of the baffle plate 130. The baffle 130 prevents hot air backflow, effectively blocking hot air from flowing back from the heat dissipation vent 122 to the air inlet 121, thus preventing hot air from being re-inhaled into the equipment and preventing the temperature inside the electrical compartment 100 from rising. It also improves heat dissipation efficiency by optimizing airflow within the electrical compartment 100, ensuring that external air enters the equipment through the air inlet and hot air is exhausted from the heat dissipation vent and drawn out of the housing 110, forming a highly efficient unidirectional airflow channel. This not only improves heat dissipation efficiency but also extends the equipment's lifespan. Furthermore, it reduces mutual interference between heat-generating components. By setting up the baffle, hot air from different heat-generating components will not interfere with each other, allowing each device to dissipate heat independently, ensuring the efficient operation of the entire electrical compartment's heat dissipation system. For example, without the baffle, hot air exhausted from the converter might enter the liquid-cooled unit's air inlet through gaps between devices, causing the liquid-cooled unit's inlet temperature to rise and affecting its heat dissipation effect.

[0037] In some embodiments, in the heat dissipation design of the electrical compartment 100, the heat dissipation component 140 is a key component to ensure efficient heat dissipation of the heat-generating devices 120 inside the enclosure 100. Specifically, the heat dissipation component 140 can be disposed at the air outlet 112 of the enclosure 110 and adapted to the air outlet 112. The adaptation of the heat dissipation component 140 to the air outlet 112 means that the size and shape of the heat dissipation component 140 and the air outlet 112 are completely compatible, thereby ensuring that the heat dissipation component 140 can work efficiently in conjunction with the airflow system inside the enclosure 110, while avoiding airflow leakage or efficiency reduction due to improper installation.

[0038] The heat dissipation assembly 140 is used to extract hot air generated by the heat dissipation vent to the outside of the housing 110. The airflow direction of the heat dissipation assembly 140 is from inside the housing 110 to the outside of the housing 110. Specifically, the air inlet 111 of the heat dissipation assembly 140 faces inward to the housing 110, and the air outlet 112 faces outward to the housing 110. When the heat dissipation assembly 140 is working, it extracts hot air generated by the heat-generating device 120 from inside the housing 110 and extracts it to the outside of the housing 110. Specifically, the heat dissipation assembly 140, like a fan, generates negative pressure through rotating blades, causing air inside the housing 110 to be drawn into the air inlet of the heat dissipation assembly 140. Since the air outlet 112 of the heat dissipation assembly 140 faces outward to the housing 110, the hot air is forcibly extracted to the outside of the housing 110. By forming an efficient heat dissipation circulation within the housing 110, the temperature inside the housing 110 is reduced, the airflow organization is optimized, and the heat dissipation efficiency is improved. In addition, the heat dissipation effect is optimized by the heat dissipation component 140, which enables the electrical compartment to maintain a good operating temperature even when operating under high load, avoiding damage caused by overheating and thus extending the service life of the electrical compartment.

[0039] For example, the air inlet of the power conversion system faces the air inlet of the enclosure, and the heat dissipation vent faces the air outlet of the enclosure. The heat dissipation components installed at the air outlet, such as the cooling fan, draw the hot air generated by the heat dissipation vent during the operation of the power conversion system to the outside of the enclosure through high-speed rotation, thereby providing heat dissipation for the power conversion system.

[0040] Understandably, the heat dissipation component 140 can improve heat dissipation efficiency. That is, by drawing the hot air generated by the heat dissipation vent to the outside of the housing 110, the heat dissipation component 140 directly reduces the temperature inside the housing. It not only optimizes the airflow organization but also ensures that cool air can efficiently enter the air inlet of the equipment and carry away the heat generated during the operation of the equipment. It also extends the life of the equipment. By optimizing the heat dissipation effect, the equipment can maintain a good operating temperature when running under high load, avoiding damage caused by overheating, thereby extending the service life of the equipment.

[0041] As can be seen from the above, the electrical compartment 100 in this embodiment includes: a housing 110, which includes an air inlet 111 and an air outlet 112, with the air inlet 111 and the air outlet 112 being arranged opposite to each other; a heating element 120, which is disposed inside the housing 110, with the air inlet 121 of the heating element 120 facing the air inlet 111 and the heat dissipation vent 122 of the heating element 120 facing the air outlet 112; a baffle plate 130, which is disposed between the heat dissipation vent 122 and the air inlet 121, for preventing the hot air generated by the heat dissipation vent 122 from flowing back to the air inlet 121; and a heat dissipation assembly 130, which is disposed at the air outlet 111 and adapted to the air outlet 111, for drawing the hot air generated by the heat dissipation vent to the outside of the housing 110. This application improves heat dissipation efficiency and extends the service life of the electrical compartment 100 by providing a baffle plate 130 between the heat dissipation port 122 and the air inlet 121 of the heat-generating device 120, thereby preventing hot air generated by the heat dissipation port 122 from flowing back to the air inlet 121.

[0042] Furthermore, in related technologies, the electrical compartment employs air cooling, typically with louvered structures at the front and rear to ensure ventilation and meet internal heat dissipation requirements. Additionally, to meet the operational needs of energy storage devices in harsh environments, the electrical compartment must be dustproof and waterproof, usually achieved by using dustproof cotton or similar methods. However, the combined design of louvers and dustproof cotton increases air resistance, hindering the exhaust of hot air generated by heat-generating components within the compartment. This causes hot air to accumulate inside, and some may even flow back to the air inlet, resulting in a continuous rise in internal temperature and impacting the compartment's performance and lifespan.

[0043] To further improve the heat dissipation efficiency and service life of the electrical compartment, please refer to [link / reference needed]. Figures 1-3 The electrical compartment 100 provided in this embodiment may also include a protective component 150.

[0044] In some embodiments, the protective component 150 may be disposed at the air inlet 111 of the enclosure 110, and the protective component 150 is adapted to the air inlet 111 to ensure that the protective component 150 can tightly cover the air inlet 111 without affecting the entry of external air into the enclosure 110 from the air inlet 111. The main function of the protective component 150 is to prevent dust and / or water from outside the enclosure 110 from entering the enclosure 110, while allowing external air to enter to meet the heat dissipation requirements of the equipment.

[0045] Optionally, the protective component 150 may include louvers 151, which are of a labyrinthine design. A labyrinthine louver is a specially designed ventilation structure with complex, tortuous internal channels that effectively prevent the direct entry of dust and water droplets. Specifically, the dustproof function of the labyrinthine louver 151 is that when dust particles enter the louver with the airflow, due to the labyrinthine channel design, the dust particles will collide and accumulate multiple times within the channels, thus being blocked inside the louver and unable to enter the electrical compartment. The waterproof function is that, for water droplets, the tortuous channels of the labyrinthine louver prevent water droplets from directly entering; even if a small amount of water droplets enters, they will accumulate within the channels and flow down the channel walls, preventing them from entering the electrical compartment.

[0046] Optionally, the protective component 150 may further include a dustproof cotton 152, which is disposed adjacent to the louver 151 and positioned between the air inlet 121 of the heating device 120 and the louver 151. This means that external dust and / or water are first filtered through the louver 151 and then further filtered by the dustproof cotton 152. The dustproof cotton 152 is a material with high porosity and high filtration performance, typically made of fibrous material, which can effectively filter dust and particles in the air.

[0047] Specifically, the dustproof function of dustproof cotton 152 is that when air passes through dustproof cotton 152, dust particles will be intercepted, adsorbed or deposited on the surface and internal pores of dustproof cotton. The pore size of dustproof cotton can be adjusted as needed to block dust particles of different sizes. The waterproof function is that the fiber structure of dustproof cotton 152 can prevent water droplets from passing through directly. When water droplets come into contact with dustproof cotton 152, they will be dispersed or adsorbed by the surface tension and capillary action of the fibers, thus preventing them from passing through smoothly. Dustproof cotton 152 can also further enhance its waterproof performance through special surface treatments such as hydrophobic coatings.

[0048] Understandably, the combination of a labyrinthine louver structure and dustproof cotton in Protective Component 140 provides more efficient dust and water protection. The labyrinthine louver structure first blocks most dust and water droplets, while the dustproof cotton further filters residual fine particles and moisture. Although the labyrinthine louvers and dustproof cotton increase wind resistance, the reasonable design of the louver opening area and the air permeability of the dustproof cotton ensures that ventilation and heat dissipation are met while meeting dust and water protection requirements. Protective Component 150, through the dual design of labyrinthine louvers and dustproof cotton, significantly improves the dust and water protection level of the electrical compartment. Even in harsh outdoor environments, the equipment can maintain good operating conditions, and while providing dust and water protection, the protective component does not hinder the entry of cool air. The reasonable design of the louver channels and the filtration performance of the dustproof cotton ensures sufficient cool air enters the enclosure to meet the heat dissipation needs of heat-generating components. Furthermore, Protective Component 150 effectively prevents dust and water from entering the enclosure, reducing the risk of equipment failure due to dust accumulation or water erosion, thereby extending the equipment's service life.

[0049] In some embodiments, the opening area of ​​the louver 151 is related to the air permeability of the dustproof component 150, the air permeability of the louver 151, and the air permeability of the dustproof cotton 152. The air permeability of the dustproof component 150 is greater than the air intake requirement of the heating element 120. The dustproof component includes labyrinth-type louvers and dustproof cotton. The air permeability of the dustproof component refers to the amount of air passing through it per unit time. To meet heat dissipation requirements, the air permeability of the dustproof component must be greater than the air intake requirement of the heating element inside the housing. Even with the filtration effect of the dustproof component, sufficient cool air must still enter the housing.

[0050] Specifically, the air permeability of venetian blinds refers to the efficiency with which they allow air to pass through. While labyrinthine venetian blinds offer good dust and water resistance, their air permeability is relatively low. Therefore, when designing venetian blinds, it is necessary to compensate for the insufficient air permeability by increasing the opening area to ensure sufficient cool air enters the enclosure. The air permeability of dustproof cotton refers to the efficiency with which it allows air to pass through. Although dustproof cotton effectively filters dust, its air permeability is also relatively low. Therefore, when designing dustproof cotton, its obstruction of airflow needs to be considered, and it should be considered in conjunction with the air permeability of the venetian blinds to ensure that the overall air permeability meets the heat dissipation requirements. It is understandable that since venetian blinds 151 and dustproof cotton 152 require relatively low air permeability to meet dust and water resistance requirements, the air intake requirements of the equipment can be met by designing an appropriate opening area.

[0051] In some embodiments, determining the opening area of ​​the louvers requires calculating the total air intake requirements of all heat-generating devices within the electrical compartment. This is typically determined based on the equipment's heat dissipation requirements and data provided by the manufacturer. Subsequently, the air permeability of the louvers and dustproof cotton is determined. Based on the total air intake requirements, the air permeability of the louvers, and the air permeability of the dustproof cotton, the opening area of ​​the louvers is calculated. Specifically, opening area = air intake requirements / (air permeability of louvers * air permeability of dustproof cotton).

[0052] It should be noted that the window area should be calculated based on the total air intake requirements of the equipment and the permeability of the louvers and dustproof cotton. The window area should be large enough to ensure that the air permeability exceeds the maximum air intake required by the equipment. Labyrinth-type louvers provide dust and water protection, while the dustproof cotton further filters dust from the air. The dustproof cotton has a low permeability, so this needs to be compensated for by increasing the window area. Additionally, a certain degree of redundancy should be considered in the design to cope with increased equipment load or changes in environmental conditions.

[0053] Please continue reading. Figures 1 to 1 The electrical compartment 100 includes multiple heat-generating devices 120. The air inlets 121 and heat dissipation vents 122 of each heat-generating device 120 are all located on the same side. The cover plates containing the air inlets 121 of each heat-generating device are on the same plane. This unified layout of the air inlets and heat dissipation vents ensures that cool air can enter each heat-generating device evenly, avoiding uneven heat dissipation due to insufficient local airflow. The heat dissipation vents of each heat-generating device are also located on the same side, typically at the rear of the equipment, facing the air outlet of the enclosure, facilitating the concentrated exhaust of hot air.

[0054] For example, suppose there are three heat-generating devices A, B, and C in the electrical compartment. The air inlets of heat-generating devices A, B, and C all face forward, and their heat dissipation vents all face backward. The covers containing the air inlets of heat-generating devices A, B, and C are located on the same plane, forming a unified air intake interface; the heat dissipation vents of heat-generating devices A, B, and C all face backward, forming a unified air outlet interface.

[0055] The baffle 130 is a crucial component in the electrical compartment's heat dissipation design. Its primary function is to prevent hot air from flowing back from the heat dissipation vents to the air inlets. The baffle 130 is located on the same plane as the cover plate at the air inlet 121 of each heat-generating device 120, optimizing space utilization and ensuring that the baffle 130 effectively covers the gaps between adjacent heat-generating devices 120. By covering these gaps, the baffle 130 prevents hot air from flowing back to the air inlets. The design ensures that cool air enters the air inlets of the heat-generating devices from the air inlets, while hot air is directly extracted from the housing after exiting the heat dissipation vents, forming an efficient unidirectional airflow channel. For example, the baffle 130 covers the gap between heat-generating devices A and B, preventing hot air from heat-generating device A from flowing back to the air inlet of heat-generating device B, and covers the gap between heat-generating devices B and C, preventing hot air from heat-generating device B from flowing back to the air inlet of heat-generating device C.

[0056] Understandably, the unified layout of the air inlets and outlets of the heat-generating devices within the electrical compartment, along with the design of the baffles, is key to optimizing airflow and improving heat dissipation efficiency. By placing the air inlets of the heat-generating devices on the same plane and covering the gaps between adjacent devices with baffles, hot air backflow can be effectively prevented, ensuring that cool air enters the equipment smoothly and hot air is expelled smoothly, thereby improving heat dissipation efficiency and extending the service life of the equipment.

[0057] Please continue reading. Figures 1-3 The airflow generated by the heat dissipation component 140 is greater than the hot airflow generated by the heat dissipation vent 122, creating a negative pressure inside the housing 110. The hot air is then drawn out of the housing 110 through the air outlet 112. Specifically, the heat dissipation component 140 uses airflow to draw the hot air from the heat dissipation vent to the outside of the housing 110, thereby reducing the temperature inside the housing 110. The greater the airflow generated by the heat dissipation component 140, the faster the hot air is drawn out, and the better the heat dissipation effect.

[0058] It should be noted that the heat dissipation component 140 is installed at the air outlet 112 at the rear of the electrical compartment. Its main function is to extract and discharge hot air from the enclosure 110 to the outside. When the heat dissipation component 140 is operating, it generates negative pressure inside the enclosure 110. Negative pressure means that the air pressure inside the enclosure 110 is lower than the external ambient air pressure. As the heat dissipation component 140 extracts hot air, a negative pressure is formed inside the enclosure 110. According to the principles of fluid dynamics, air will flow from the area of ​​high pressure (the external environment) to the area of ​​low pressure (the enclosure). Therefore, cool air from the outside will be naturally drawn into the enclosure, thus achieving a heat dissipation effect. In addition, the protective component 150 is located at the air inlet 111 of the enclosure 110. Its design allows external air to enter the enclosure 110. Due to the existence of negative pressure, external air will enter the enclosure 110 through the protective component 150, replenishing the hot air extracted by the heat dissipation component 140, forming a unidirectional airflow path from the protective component 150 to the heat dissipation component 140.

[0059] Understandably, the airflow of the heat dissipation component 140 is greater than the total hot airflow generated by the heat dissipation vents, ensuring that hot air is quickly expelled and preventing the cabin temperature from rising. The suction effect of the heat dissipation component 140 creates negative pressure, drawing cool air from the protective component 150 to maintain good airflow circulation. Furthermore, the increased airflow due to the negative pressure provides redundancy for the system, ensuring that the heat dissipation system continues to operate effectively when equipment load increases or ambient temperature rises.

[0060] Optionally, in some embodiments, the heat dissipation assembly 140 includes at least one cooling fan, with a dustproof and waterproof component disposed on the side of the cooling fan away from the heat-generating device 120, and the air outlet direction of each cooling fan is towards the heat-generating device 120.

[0061] Specifically, in the heat dissipation design of the electrical compartment of energy storage equipment, heat dissipation components such as cooling fans are key components for achieving efficient heat dissipation. The heat dissipation component 140 includes at least one cooling fan, which is mounted on the side away from the heat-generating device 120. Mounting the cooling fan at the rear or side of the heat-generating device, rather than directly against it, prevents damage due to high temperatures and ensures that the cooling fan can effectively extract hot air from the enclosure. The exhaust direction of each cooling fan is directed towards the heat-generating device 120, ensuring that hot air is quickly extracted. This optimized airflow design avoids airflow turbulence and improves heat dissipation efficiency.

[0062] A dustproof and waterproof component is installed on the side of the cooling fan away from the heat-generating components. The main function of this component is to protect the cooling fan from dust and water corrosion without affecting its heat dissipation performance. This component can be a special housing, a waterproof coating, or a dustproof mesh, effectively preventing dust and water from entering the cooling fan and extending its lifespan. The dustproof and waterproof component is installed on the side of the cooling fan away from the heat-generating components to prevent dust or water from being drawn into the housing by the airflow generated during fan operation.

[0063] Understandably, the cooling fan's exhaust direction is towards the heat-generating components, ensuring hot air is quickly extracted from the enclosure and optimizing airflow. The layout, away from heat-generating components, prevents the cooling fan from being damaged by high temperatures, extending its lifespan. Dustproof and waterproof components effectively prevent dust and water from entering the cooling fan, ensuring normal operation even in harsh environments. The design of these dustproof and waterproof components does not affect the cooling fan's heat dissipation performance, ensuring unaffected cooling efficiency. Through optimized heat dissipation component design, heat-generating components can operate within a suitable temperature range, preventing damage due to overheating and thus extending the equipment's lifespan.

[0065] Specifically, in electrochemical energy storage, lithium-ion batteries have high energy density, high charge and discharge efficiency, and long lifespan, and are widely used in electric vehicles and energy storage systems; lead-acid batteries have low cost but short lifespan and low energy density, and are mainly used as backup power; flow batteries, such as vanadium redox flow batteries, are suitable for large-scale energy storage, and energy and power can be designed independently; sodium-sulfur batteries have high energy density and are suitable for large-scale energy storage, but require a high-temperature environment.

[0066] Mechanical energy storage includes pumped hydro storage, which utilizes the potential energy of water to pump water to an upper reservoir during periods of low electricity demand and generate electricity during peak periods. This technology is mature and suitable for large-scale energy storage. Compressed air energy storage stores energy by compressing air, which drives a turbine to generate electricity when released. Flywheel energy storage uses a rotating flywheel to store kinetic energy, has a fast response speed, and is suitable for high-frequency charging and discharging.

[0067] Electromagnetic energy storage uses supercapacitors for fast charging and discharging, making them suitable for high-power applications, but they have low energy density. Superconducting magnetic energy storage utilizes the properties of superconductors to store electrical energy, resulting in high energy density and low loss.

[0068] Thermal energy storage uses phase change materials or thermal storage tanks to store thermal energy for heating, cooling or power generation.

[0069] Hydrogen energy storage involves producing hydrogen through water electrolysis, storing the energy, and then releasing it through fuel cells and other methods, making it suitable for large-scale, long-term energy storage.
