Description

Technical Field

[0001] This utility model relates to a fireproof and heat-insulating CCS structure, and more particularly to a fireproof and heat-insulating CCS structure suitable for energy storage batteries and power batteries. Background Technology

[0002] With the increasing popularity of electric vehicles, battery pack safety has become a growing concern. Battery-induced fires can cause rapid vehicle combustion, posing a serious threat to passenger safety. Therefore, to prevent battery pack fires from endangering passenger safety, fireproofing and heat insulation measures are essential, with the core being the effective prevention of potential hazards to the passenger compartment from a fire in the battery cells. Currently, most CCS (Cleanroom Control System) structures used in energy storage and power batteries lack fireproof and heat-insulating CCS structures. Therefore, there is an urgent need to provide a fireproof and heat-insulating CCS structure suitable for both energy storage and power batteries. Utility Model Content

[0003] To address the shortcomings of the aforementioned technologies, this invention provides a fireproof and heat-insulating CCS structure suitable for energy storage batteries and power batteries.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] Example

[0022] This embodiment discloses a fireproof and heat-insulating CCS structure suitable for energy storage batteries and power batteries, such as... Figure 1 and Figure 2 As shown, it includes an injection-molded partition 1, an aluminum bar 2, a fireproof and heat-insulating body 4, and an FPC 4;

[0023] Among them, the injection-molded isolation panel 1 serves as the main load-bearing structure and is used for the installation of structures such as aluminum bar 2 and fireproof insulation 3;

[0024] As an important component for current collection and transmission, the aluminum bar 2 is installed in the corresponding aluminum bar groove 11 on the injection-molded isolation plate 1. At the same time, the aluminum bar 2 is electrically connected to the FPC (flexible printed circuit) 4. The FPC 4 can be electrically connected to the aluminum bar 2 through the nickel sheet 5, thereby realizing functions such as voltage acquisition.

[0025] The fireproof and heat-insulating body 3 is the main structural component of the fireproof and heat-insulating CCS structure in this embodiment to achieve fireproof and heat-insulating performance. The fireproof and heat-insulating body 3 is made of mica sheet material. As a heat insulation material, mica sheet has the performance of effectively blocking heat transfer and protecting the FPC from heat damage. At the same time, mica sheet also exhibits excellent fireproof and heat-insulating performance, which can effectively block the penetration of explosion-proof valve spray and flames, and ensure the safety of the passenger cabin.

[0026] The FPC4 is installed based on the fireproof and heat-insulating body 3, such as... Figure 3 As shown, the fireproof and heat-insulating body 3 is designed with a specific shape, that is: the fireproof and heat-insulating body 3 is long and narrow, and a flat plate part 32 is formed by folding the middle protrusion 31 along both sides.

[0027] The flat plate 32 formed by the folding is planar, serving two purposes: firstly, for the installation of the FPC4, and secondly, for good contact and adhesion with the injection-molded separator 1, thus fixing the FPC4 and the fireproof and heat-insulating body 3 together on the injection-molded separator 1. Furthermore, the FPC4 installed on the flat plate 32 can also be in close contact with the aluminum busbar 2, facilitating electrical connection between the aluminum busbar 2 and the FPC4. This specific spatial layout offers the advantage of a compact overall design, minimizing the use of internal battery pack space.

[0028] like Figure 1 As shown, the FPC4 and the fireproof insulation 3 are specifically fixed to the injection-molded isolation plate 1 by hot riveting through the hot riveting post 6. Accordingly, fixing holes for the hot riveting post 6 to pass through need to be pre-drilled in the flat plate part 32 of the fireproof insulation 3 and the corresponding position of the FPC4.

[0029] Furthermore, preferably, a hole 12 is provided on the injection-molded isolation plate 1, with the hole 12 facing the back side of the protrusion 31. This hole 12 is specifically reserved for the explosion-proof valve of the battery cell, so that in the event of a battery cell fire, the flame can be sprayed in the direction of the opening. In addition, this hole also functions as a flue, ensuring that toxic and harmful gases generated when the battery cell catches fire can be discharged through this channel, preventing them from directly entering the passenger compartment. During normal operation, if the battery cell temperature is too high, this area also serves as a hot air vent, playing a certain role in heat dissipation, thereby maintaining the good heat dissipation performance of this fireproof and heat-insulating CCS structure.

[0030] Furthermore, the injection-molded isolation plate containing the aluminum bar groove has a small hole structure, which is the customer's welding area for weld point inspection on the customer's production line.

[0031] Therefore, the fireproof and heat-insulating CCS structure disclosed in this embodiment, applicable to energy storage batteries and power batteries, aims to prevent splashing from the battery cell explosion-proof valve. Its fireproof and heat-insulating body is made of mica sheet, disposed on an injection-molded separator plate, and thermally riveted to the FPC via hot-riveting posts on the injection-molded separator plate. In the event of a fire in the automotive battery pack or splashing from the cell explosion-proof valve, this fireproof and heat-insulating body can effectively suppress the splashing of chemical substances and the spread of flames, thereby ensuring the safety of the passenger compartment. Simultaneously, this fireproof and heat-insulating structure possesses excellent heat resistance and insulation properties, maintaining structural stability and functional integrity even in extreme high-temperature environments. Furthermore, as a heat-insulating material, mica sheet not only has excellent high-temperature resistance but also effectively isolates heat transfer, slowing down the rapid rise in internal temperature of the battery pack, providing a solid barrier for the safety protection of the battery system.

[0032] Compared with existing technologies, it has the following technological advantages:

[0033] 1) Fireproof and heat-insulating materials made of mica sheets form the main heat insulation structure, which has effective fireproof and heat-insulating performance and can block the penetration of explosion-proof valve spray and flames, ensuring the safety of the passenger cabin.

[0034] 2) The fire-resistant and heat-insulating structure can also effectively block heat transfer, thereby protecting the FPC from damage;

[0035] 3) The overall structure of this new type is compact and does not occupy too much internal space of the battery pack, while maintaining a good heat dissipation channel to balance the needs of thermal management and safety protection.

[0036] In summary, the fireproof and heat-insulating CCS structure proposed in this utility model not only solves the shortcomings of the existing technology, but also significantly improves durability, versatility and thermal management, providing strong protection for the safety performance of energy storage batteries and power batteries, and has broad application prospects and social value.

[0037] Furthermore, it should be noted that the fireproof and heat-insulating CCS structure provided by this invention is not only applicable to energy storage batteries and power batteries, but can also be extended to other electronic equipment fields that require efficient thermal management and safety protection.

[0038] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
