Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically to an integrated energy storage, control and protection battery with an IP68 protection rating. Background Technology

[0002] Solar streetlights are powered by crystalline silicon solar cells, store energy in maintenance-free valve-regulated sealed batteries, use ultra-bright LED lights as the light source, and are controlled by an intelligent charge and discharge controller. They are used to replace traditional public power lighting streetlights.

[0003] Conventional solar streetlights use batteries with poor waterproofing, making the casing prone to corrosion and difficult to repair or replace. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an integrated energy storage, control, and protection battery with an IP68 protection rating, thus solving the problems raised in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An integrated energy storage, control, and protection battery with an IP68 protection rating includes a mounting frame, a battery casing, and a foam layer. A frame is fixedly mounted to the top of the mounting frame using bolts. An installation groove is formed inside the frame, and the battery casing is housed within the groove. A battery and a solar controller are encapsulated inside the battery casing using potting compound. Sealing plates are provided on both sides of the battery casing. An anti-corrosion coating is applied to the outer surface of the battery casing, and a waterproof coating is applied to the outer surface of the anti-corrosion coating. A high-temperature resistant layer is provided on the inner wall of the battery casing. A first fireproof layer is applied to the outer surface of the high-temperature resistant layer, and a second fireproof layer is applied to the outer surface of the first fireproof layer. An outer frame is provided at the top of the frame, and a solar panel is housed inside the outer frame.

[0007] Preferably, the gap between the inner wall of the battery casing and the battery is filled with a foam layer that does not react with adhesive, and the foam layer is made of EVA material.

[0008] Preferably, the adhesive used in the potting encapsulation is epoxy resin potting compound or silicone rubber potting compound.

[0009] Preferably, the waterproof coating is a polyurethane coating.

[0010] Preferably, the anti-corrosion coating is a polytetrafluoroethylene coating.

[0011] Preferably, the high-temperature resistant layer is made of fluorocarbon resin material.

[0012] Preferably, the first fireproof layer is made of fireproof ceramic fiber material, and the second fireproof layer is made of polyvinyl chloride material.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0014] This utility model provides an integrated energy storage, control, and protection battery with an IP68 protection rating. The battery casing is housed within a frame, and the battery and solar controller are encapsulated within the casing using potting compound, forming an integrated design structure. This significantly saves space, shortens circuit length, and reduces power loss. An anti-corrosion coating on the outer surface of the battery casing provides corrosion resistance, effectively preventing external erosion of the battery and solar controller. A waterproof coating is applied to the outer surface of the anti-corrosion coating, and the potting compound uses epoxy resin or silicone rubber, achieving IP68 waterproofing and improving the casing's waterproof performance. A high-temperature resistant layer enhances the casing's high-temperature resistance, and a first and second fire-resistant layer significantly improves the casing's fire resistance, preventing damage to the casing in the event of a battery explosion or fire.

[0015] This invention fills the gap between the inner wall of the battery casing and the battery with a foam layer that does not react with adhesive. When adhesive is poured into the battery casing, only a small amount of adhesive is needed to fill the battery casing due to the foam layer, thus greatly reducing the amount of adhesive used. The foam layer is made of EVA material, which is lightweight and greatly reduces the overall weight of the battery casing. Attached Figure Description

The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0021] According to an embodiment of the present invention, an integrated energy storage, control, and protection battery with an IP68 protection rating is provided.

[0022] Example 1:

[0023] As shown in the attached diagram of the instruction manual. Figure 1 As shown, a high-efficiency LED solar street light includes a mounting frame 1, a battery casing 4, and a foam layer 13. A frame 2 is fixedly mounted on the top of the mounting frame 1 by fixing bolts. The frame 2 has an internal mounting groove 3, and the battery casing 4 is disposed in the mounting groove 3. A battery 11 and a solar controller 12 are disposed inside the battery casing 4 by encapsulation with potting compound. Sealing plates 10 are provided on both sides of the battery casing 4. The outer surface of the battery casing 4 is coated with an anti-corrosion coating 6, and the outer surface of the anti-corrosion coating 6 is coated with a waterproof coating 5. A high-temperature resistant layer 7 is provided on the inner sidewall of the battery casing 4. A first fireproof layer 8 is provided on the outer surface of the high-temperature resistant layer 7, and a second fireproof layer 9 is provided on the outer surface of the first fireproof layer 8. An outer frame 14 is provided on the top of the frame 2, and a solar panel 15 is disposed inside the outer frame 14.

[0024] The waterproof coating 5 is made of polyurethane. Polyurethane has excellent thermal insulation properties, is resistant to chemicals, is easy to process, and has good waterproof performance.

[0025] The anti-corrosion coating 6 is made of polytetrafluoroethylene (PTFE). PTFE has excellent corrosion resistance and can resist the erosion of most chemicals. It is almost insoluble in any solvent and exhibits strong inertness to a variety of chemicals such as acids, alkalis, and salts.

[0026] The high-temperature resistant layer 7 is made of fluorocarbon resin material, which has good heat resistance, chemical resistance, cold resistance and low-temperature flexibility.

[0027] Example 2:

[0028] As shown in the attached diagram of the instruction manual. Figure 1 , Figure 2 and Figure 3As shown, an integrated energy storage, control, and protection battery with an IP68 protection rating is constructed by housing a battery casing 4 within a frame 2. The battery 11 and solar controller 12 are encapsulated within the casing 4 using potting compound, forming a unified design that significantly saves space, shortens circuit length, and reduces power loss. An anti-corrosion coating 6 is applied to the outer surface of the battery casing 4, providing corrosion resistance and effectively preventing external corrosion of the battery 11 and solar controller 12. A waterproof coating 5 is applied to the outer surface of the anti-corrosion coating 6, using epoxy resin or silicone rubber potting compound, achieving IP68 waterproof rating for the battery 11 and improving the waterproof performance of the battery casing 4. A high-temperature resistant layer 7 further enhances the high-temperature resistance of the battery casing 4. By incorporating a first fireproof layer 8 and a second fireproof layer 9, with the first fireproof layer 8 made of fire-resistant ceramic fiber and the second fireproof layer 9 made of polyvinyl chloride, the fire resistance of the battery casing 4 is significantly improved, preventing damage to the battery casing 4 in the event of an explosion or fire in the battery 11. By filling the gap between the inner wall of the battery casing 4 and the battery 11 with a non-reactive foam layer 13, when glue is injected into the battery casing 4, only a small amount of glue is needed to fill the casing 4, thus greatly reducing the amount of glue used. The foam layer 13 is made of EVA material, and because EVA material is lightweight, it significantly reduces the overall weight of the battery casing 4.
