Description

Technical Field

[0001] This utility model belongs to the field of energy storage technology, specifically relating to energy storage units and energy storage devices. Background Technology

[0002] Energy storage devices are electrical energy storage and transfer equipment. They contain multiple battery packs and are characterized by convenient installation and transportation, high integration, small footprint, and good scalability. They are an important component of the development of distributed energy, smart grids, and the energy internet in energy storage systems.

[0003] The existing technology includes an energy storage unit and energy storage device with patent publication number CN221057622U. The patent includes an energy storage component and a gas collection component. The energy storage component includes a connecting component and at least one battery pack. The gas collection component is provided with a cavity for containing flue gas. The gas collection component includes an inlet and an outlet of the connecting cavity. The inlet is connected to the interior of at least one battery pack through the connecting component, and the outlet is used to connect to the external environment. Therefore, when a battery cell in the battery pack experiences thermal runaway, the flue gas generated can be discharged into the cavity of the gas collection component through the connecting component and discharged into the external environment through the outlet. This can reduce the risk of flue gas accumulation in the gas collection component and thus the risk of explosion, improving safety performance. However, in actual use, there are still the following shortcomings: From a practical point of view, when the energy storage unit is used, the heat generated inside cannot be detected in real time, which may lead to overheating and cause safety hazards to the battery cells. It is also impossible to perform real-time heat dissipation, which reduces the safety and stability of the device.

[0004] Therefore, energy storage units and devices are needed to solve the problems of real-time heat detection and heat dissipation in existing technologies. Utility Model Content

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0024] The directional terms used in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of this application.

[0025] Please see Figure 1-4This utility model provides an energy storage unit 100, which includes a top cover 10, a housing 20, and a battery cell 30. The battery cell 30 is disposed inside the housing 20. The top cover 10 is fixedly installed on the upper part of the housing 20. A heat dissipation mechanism 40 is provided on the top cover 10 for dissipating heat from the battery cell 30. A connecting member 200 is connected to the energy storage unit 100. A gas collecting member 300 is fixedly connected to the connecting member 200. A gas collecting member 400 is connected to one side of the gas collecting member 300 through the connecting member 200.

[0026] By using the heat dissipation mechanism 40 installed on the energy storage unit 100, the heat of the battery cells 30 inside the housing 20 can be monitored in real time, thereby effectively preventing the battery cells 30 from overheating and causing the heat to be unable to dissipate, which would affect the normal use of the energy storage unit 100. This improves the safety and stability of the energy storage unit 100 during use.

[0027] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that the heat dissipation mechanism 40 includes a mounting plate 401, which is fixedly installed inside the upper cover 10. Heat dissipation fins 402 are fixedly connected to the mounting plate 401. Several heat dissipation fins 402 are evenly installed through the mounting plate 401. The bottom plane of the heat dissipation fins 402 is flush with the upper plane of the battery cell 30. A heat dissipation chamber 403 is provided between the upper part of the mounting plate 401 and the inner side of the upper cover 10. A vent 404 is opened on the right side of the heat dissipation chamber 403 on the right side of the upper cover 10. A dustproof net 405 is fixedly connected to the outer side of the vent 404 on the upper cover 10. A fixing frame 406 is fixedly installed on the left side of the heat dissipation chamber 403 on the left side of the upper cover 10. A fan 407 is fixedly installed inside the fixing frame 406. A filter 408 is fixedly connected to the left side of the fan 407 on the left side of the fixing frame 406. A temperature sensor 409 is fixedly installed at the front and back of the inner side of the upper cover 10 below the mounting plate 401.

[0028] During use, the temperature sensor 409 monitors the heat of the battery cells 30 inside the energy storage unit 100. When the internal heat is too high, the fan 407 is activated to circulate air within the heat dissipation chamber 403. The dustproof net 405 and filter 408 effectively prevent dust from entering, thereby improving the heat dissipation efficiency within the heat dissipation chamber 403. The heat transfer from the battery cells 30 to the heat dissipation fins 402, combined with the operation of the fan 407, accelerates the heat dissipation efficiency of the heat dissipation fins 402, thus improving the heat dissipation efficiency of the battery cells 30. This ensures that the battery cells 30 can operate stably within the energy storage unit 100, thereby improving its safety during use.

[0029] On the other hand, this application also provides an energy storage device, including the energy storage unit of any of the above.

[0030] This solution has the following working process: When this device is in use, multiple energy storage units 100 are connected through the connecting member 200 and connected to the gas collection member 300 to discharge the flue gas inside the energy storage unit 100 to ensure its operation. At the same time, the temperature sensor 409 installed in the upper cover 10 can monitor the heat of the battery cells 30 inside the energy storage unit 100. When the heat inside is too high, the fan 407 is run to circulate the air in the heat dissipation chamber 403. The dustproof net 405 and filter 408 can effectively prevent dust from entering, thereby improving the heat dissipation efficiency in the heat dissipation chamber 403. The heat transfer of heat on the battery cells 30 through the heat dissipation fins 402, combined with the operation of the fan 407, accelerates the heat dissipation efficiency of the heat dissipation fins 402, thereby improving the heat dissipation efficiency of the battery cells 30. This ensures that the battery cells 30 can operate stably in the energy storage unit 100, thereby improving its safety during use.

[0031] In summary, by using the heat dissipation mechanism 40 on the energy storage unit 100, the heat of the battery cells 30 inside the housing 20 can be monitored in real time, thereby effectively preventing the battery cells 30 from overheating and causing the heat to be unable to dissipate, which would affect the normal use of the energy storage unit 100. This improves the safety and stability of the energy storage unit 100 during use.
