Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment technology, and more specifically, to an energy storage data traceability and recording device and an energy storage equipment. Background Technology

[0002] In energy storage systems, fires and explosions can occur due to factors such as battery thermal runaway, mismanagement, and aging wiring. These fires often trigger the system's fire suppression system. During this process, monitoring electronic equipment is frequently destroyed by fire or submerged in water from the fire suppression system, resulting in the loss of critical data and severely complicating accident investigations to determine the cause of the malfunction. If the accident investigation fails to identify the specific cause, it becomes impossible to prevent similar accidents from happening again. Utility Model Content

[0029] Please refer to the reference. Figures 1 to 4 This application provides an energy storage data traceability and waveform recording device, including a core plate 50, an outer shell 10 covering the core plate 50, and a fireproof and heat-insulating cover 20 disposed between the core plate 50 and the outer shell 10. This energy storage data traceability and waveform recording device provides dual protection for the core plate 50 through the outer shell 10 and the fireproof and heat-insulating cover 20, enabling the core plate 50 to withstand harsh environments such as high temperatures, fire, water immersion, explosion impact, and mechanical impact.

[0030] It should be noted that, as Figure 1 As shown, the energy storage data traceability and recording device includes a core plate 50 to store various data of the energy storage device and to monitor and record changes in electrical parameters (such as current and voltage) of the energy storage device when a fault occurs, so that engineers can perform fault analysis and diagnosis during accident investigation, thereby reducing power outage time and maintenance costs.

[0031] Based on this, such as Figure 1As shown, the energy storage data traceability and recording device also includes an outer shell 10 and a fireproof and heat-insulating cover 20. The outer shell 10 covers the core plate 50, and the fireproof and heat-insulating cover 20 is disposed between the core plate 50 and the outer shell 10. In other words, the fireproof and heat-insulating cover 20 covers the core plate 50, and the outer shell 10 covers the fireproof and heat-insulating cover 20, so that the outer shell 10 and the fireproof and heat-insulating cover 20 can play a dual protection role. Furthermore, under the fireproof and heat-insulating effect of the fireproof and heat-insulating cover 20, it can cope with harsh environments such as high temperature and fire. At the same time, under the sealing protection of the outer shell 10, it can cope with harsh environments such as water immersion and explosive impact.

[0032] The outer casing 10 can be made of a metal with high hardness to ensure that it is not damaged by harsh environments such as explosions or mechanical impacts, thus ensuring that it can always provide a sealing protection for the core plate 50. In addition, the outer casing 10 can be made of a metal with good heat dissipation, such as aluminum alloy, to ensure that it can dissipate heat quickly in harsh environments such as high temperatures or fires, and to prevent heat from accumulating on the surface of the outer casing 10 and affecting the core plate 50. Furthermore, the outer casing 10 can be pre-treated with anti-corrosion measures, such as anodizing, to ensure that it is not prone to rust when immersed in water, thus ensuring that it can withstand harsh environments such as water immersion.

[0033] To prevent the sealing and protective functions of the outer shell 10 and the fireproof and heat-insulating cover 20 from decreasing or failing under high-temperature environments and prolonged environmental aging, thus causing damage to the core plate 50, as one possible implementation method, such as Figure 1 As shown, a potting layer 30 formed of potting material is also provided between the core plate 50 and the fireproof and heat-insulating shell 20 to achieve the purpose of sealing and protection through potting treatment. The potting material can have a certain degree of flexibility so that the potting layer 30 can play a good buffering role when facing harsh environments such as explosion impact and mechanical impact, thereby further sealing, buffering and protecting the core plate 50; the potting material can also have the characteristics of insulation, low thermal conductivity and waterproofness, which can further protect the core plate 50.

[0034] In some embodiments, the energy storage data tracing and recording device further includes a connector 40, which is fixedly and sealed onto the fireproof and heat-insulating housing 20. One end of the connector 40 protrudes outside the fireproof and heat-insulating housing 20, and the other end extends into the fireproof and heat-insulating housing 20, so that potting material is injected between the core plate 50 and the fireproof and heat-insulating housing 20 via the connector 40. Alternatively, in other embodiments, such as Figure 1As shown, the energy storage data traceability and recording device also includes a connector 40, which is fixedly and sealed on the housing 10. One end of the connector 40 is exposed outside the housing 10, and the other end extends into the fireproof and heat-insulating cover 20, so that the potting material is injected between the core plate 50 and the fireproof and heat-insulating cover 20 through the connector 40.

[0035] Regardless of whether the connector 40 is installed on the fireproof and heat-insulating cover 20 or the outer shell 10, one end of the connector 40 must protrude outside the fireproof and heat-insulating cover 20, and the other end must extend into the fireproof and heat-insulating cover 20. This allows the potting material to be injected through the connector 40 into the predetermined space between the outer wall of the core plate 50 and the inner wall of the fireproof and heat-insulating cover 20, and finally cure to form the potting cover layer 30. For the installation method of the connector 40, mounting holes can be provided on the fireproof and heat-insulating cover and / or the outer shell 10, allowing for fixing connections not only through bolts 41, screws, and other connectors, but also through sealing rings. The specific material selection for the connector 40 requires a waterproof and high-temperature resistant connector.

[0036] As one possible implementation method, such as Figures 1 to 4 As shown, the fireproof and heat-insulating cover 20 includes an interlocking heat-insulating shell 21 and a heat-insulating bottom cover 22, which together form a cavity for accommodating the core plate 50. For example, in this embodiment, as... Figures 2 to 4 As shown, a first groove 212 is provided on the heat insulation shell 21, and a second groove 222 is provided on the heat insulation bottom cover 22. The first groove 212 of the heat insulation shell 21 and the second groove 222 of the heat insulation bottom cover 22 together form the cavity described above.

[0037] In actual installation, the energy storage data traceability and recording device can be installed at the bottom of the energy storage equipment container, so that it can better exchange heat with the ambient temperature air in the external environment. This allows some of the heat radiated from the high-temperature environment to the surface of the outer shell 10 to be directly dissipated, while the other part of the heat can be blocked by the fireproof and heat-insulating cover 20. Alternatively, it can be installed with the heat-insulating shell 21 facing upwards and the heat-insulating bottom cover 22 facing downwards. In this case, the bottom of the heat-insulating shell 21 is closer to the heat source, and as the main heat-receiving surface, it can be designed to be thicker, for example, 25mm. The bottom of the heat-insulating bottom cover 22 is relatively far from the heat source, and as the secondary heat-receiving surface, it can be designed to be thinner, for example, 5mm. Regarding the arrangement of the fireproof and heat-insulating cover 20 and the thickness of the bottom of the heat-insulating shell 21 and the heat-insulating bottom cover 22, those skilled in the art should be able to make reasonable selections and designs according to the actual situation, and no specific restrictions are made here.

[0038] As one possible implementation method, such as Figures 2 to 4As shown, the heat insulation housing 21 is provided with a first snap-fit ​​portion 211, and the heat insulation bottom cover 22 is correspondingly provided with a second snap-fit ​​portion 221. The first snap-fit ​​portion 211 and the second snap-fit ​​portion 221 are snapped together. In this embodiment, as... Figures 2 to 4 As shown, the first snap-fit ​​part 211 is a snap-fit ​​groove, and the second snap-fit ​​part 221 is a snap-fit ​​block, so that the heat insulation shell 21 and the heat insulation bottom cover 22 can be fixed and sealed by the snap-fit ​​groove and the snap-fit ​​block.

[0039] As one possible implementation method, such as Figure 1 As shown, the outer casing 10 includes a base 11, a cover plate 12, and a housing 13 connecting the base 11 and the cover plate 12. The base 11 and the housing 13, as well as the cover plate 12 and the housing 13, are connected by fasteners via threads. For example, in this embodiment, threaded holes are provided at the connection points of the base 11 and the housing 13, as well as the cover plate 12 and the housing 13. Fasteners are sequentially inserted into the threaded holes on each pair of surfaces to achieve a threaded connection between them.

[0040] As one possible implementation method, such as Figure 1 As shown, a sealing element 14, such as a sealing ring, is provided between the base 11 and the housing 13, as well as between the cover plate 12 and the housing 13. The sealing and protection performance of the housing 10 can be improved by the sealing element 14.

[0041] As one possible implementation method, the fireproof and heat-insulating shell 20 is made of fireproof and heat-insulating material. The thermal conductivity of the fireproof and heat-insulating material is less than 0.021 W / mK at 400℃. The fireproof and heat-insulating material can be a nano-sized microporous material to achieve the purpose of fireproofing and heat insulation. In addition, the thermal resistance of the fireproof and heat-insulating material can be designed according to the thermal resistance formula (1), and the thermal resistance can be designed to be about 54 W / ℃. If the internal space of the shell 10 allows, the thermal resistance can be designed to be higher, so as to achieve the purpose of blocking the high-temperature damage of heat radiation to the internal core plate 50.
