Description

Technical Field

[0001] This utility model belongs to the field of battery pack technology, specifically relating to a graphene battery pack. Background Technology

[0002] Graphene batteries have demonstrated enormous application potential in materials science due to their superior energy density, fast charging capability, and long cycle life. These batteries primarily rely on the unique properties of graphene electrodes. However, due to the inherent characteristics of graphene materials, their application also faces some challenges. First, the low shear strength of single-layer or few-layer graphene makes it prone to interlayer slippage or fracture under severe impacts, leading to the shedding of active material and ultimately a sharp drop in capacity. This structural sensitivity is an issue that requires special attention during design and use.

[0003] Secondly, due to its extremely high specific surface area, graphene is exceptionally sensitive to moisture and oxygen. If the battery pack deforms or fails to seal during an impact, moisture can easily penetrate, accelerating electrolyte decomposition and electrode interface corrosion. This not only reduces battery performance but may also trigger more serious safety issues, such as uncontrolled internal chemical reactions causing the battery to overheat and potentially leading to thermal runaway, posing a threat to equipment and personal safety.

[0004] The sides of graphene battery packs are high-risk areas for impact, therefore, when using graphene battery packs, the sides of the packs need to be protected. Utility Model Content

[0027] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0028] like Figures 1 to 6 As shown, a graphene battery pack according to one embodiment of the present invention includes a battery pack body 11. Support seats 21 are fixedly connected to the upper and lower ends of the battery pack body 11, and a plurality of protective posts 22 are arranged between the support seats 21 to surround the side of the battery pack body 11. A buffer structure is provided between the protective posts 22 and the support seats 21, and there is a gap between the protective posts 22 and the battery pack body 11.

[0029] Specifically, multiple protective posts 22 correspond to the side end faces of the battery pack body 11 respectively. The buffer structure includes a limiting groove 31 opened in the support base 21. The upper and lower ends of the protective posts 22 are respectively fixedly connected to buffer blocks 32 that match the limiting groove 31. A buffer spring 33 is fixedly connected between the buffer block 32 and the front wall of the limiting groove 31.

[0030] Multiple protective pillars 22 can protect the side surface of the battery pack body 11. There is a gap between the protective pillars 22 and the battery pack body 11, and the protective pillars 22 do not directly contact the side surface of the battery pack body 11. When an external force impacts the protective pillars 22, there is enough buffer space to buffer the impact and the battery pack body 11 will not be impacted.

[0031] A main protective plate 23 is provided on the protective post 22, and a main protective pad 24 is fixedly connected to the main protective plate 23. The main protective plate 23 includes multiple secondary protective plates 231 fixedly connected to the main protective plate 23, and the main protective pad 24 includes multiple secondary protective pads 241 fixedly connected to the main protective pad 24. The main protective pad 24 is fixedly connected to the main protective plate 23. When the main protective plate 23 is fixed to the outside of the protective post 22, the main protective pad 24 faces outward. The main protective plate 23 and the main protective pad 24 can further increase the protection area of ​​the side end face of the battery pack body 11.

[0032] Furthermore, the main protective plate 23 is a metal plate with high strength and good heat conduction. The main protective pad 24 has an elastic buffering effect. When an external force impacts, the main protective pad 24 and the main protective plate 23 can better protect the side surface of the battery pack body 11.

[0033] The protective column 22 has a receiving cavity, and a heat-absorbing element is installed inside the receiving cavity. The heat-absorbing element is paraffin wax. As a conventional phase change material, paraffin wax melts after absorbing heat and does not volatilize. The front and rear shells of the protective column 22 are respectively provided with fixing grooves 25, and fixing plates 232 that match the fixing grooves 25 are fixedly connected to the main protective plate 23.

[0034] Specifically, the fixing plate 232 can be snapped into the fixing groove 25, which facilitates fixing the main protective plate 23 to the outside and inside of the protective post 22. When the main protective plate 23 is fixed to the outside of the protective post 22, the main protective pad 24 faces outward, which can further protect the side end face of the battery pack body 11. When the main protective plate 23 is fixed to the inside of the protective post 22, the main protective pad 24 contacts the shell surface of the battery pack body 11.

[0035] The main protective pad 24 is a thermally conductive pad, specifically a silicone thermally conductive pad, and the main protective plate 23 is a metal plate that can conduct heat. Through the main protective pad 24 and the main protective plate 23, the heat on the battery pack body 11 can be transferred to the protective post 22, and the heat is absorbed by the paraffin inside the protective post 22.

[0036] Some existing high-end electric vehicles can detect the temperature of graphene battery packs. When the temperature is high, the graphene battery pack can be removed and cooled by an external air-cooling structure, such as a fan, to prevent the graphene battery pack from overheating and causing damage.

[0037] When there is no cooling structure such as a fan, the main protective plate 23 can be fixed to the inside of the protective post 22, so that the main protective pad 24 contacts the battery pack body 11, and the heat on the battery pack body 11 is transferred to the protective post 22, so that the temperature of the graphene battery pack drops to a safe range.

[0038] There is a gap between the protective post 22 and the rear wall of the limiting groove 31. A handle 221 is fixedly connected to the protective post 22. The handle 221 makes it easy to pull the protective post 22. The protective post 22 drives the main protective plate 23 to move backward and place the main protective plate 23 inside the protective post 22. When the protective post 22 is loosened, the fixing plate 232 is engaged in the fixing groove 25. Under the action of the buffer spring 33, the protective post 22 can squeeze the main protective plate 23 and the main protective pad 24, so that the main protective pad 24 is in close contact with the battery pack body 11, increasing the heat conduction effect.

[0039] When using, refer to Figures 1-6 As shown, the protective posts 22 arranged around the side end face of the battery pack body 11 can protect the side end face of the battery pack body 11, and the main protective plate 23 and main protective pad 24 fixed on the outside of the protective posts 22 can increase the protective effect of the battery pack body 11.

[0040] When the temperature of the graphene battery pack is high, the main protective plate 23 is removed and fixed to the inside of the protective post 22, so that the main protective pad 24 is in contact with the battery pack body 11. The heat on the battery pack body 11 is transferred to the protective post 22 through the main protective pad 24 and the main protective plate 23. The heat is absorbed by the heat-absorbing element in the protective post 22, so that the temperature of the battery pack drops.

[0041] Compared with the prior art, the graphene battery pack of this utility model can protect the sides of the graphene battery pack, has a simple structure, and is easy to operate.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
