It is used to realize buffering energy absorption between battery pack cells.
Silicone foam insulation has emerged as a superior solution for battery protection and thermal management systems in the rapidly evolving field of new energy vehicles (NEVs). This article delves into the inherent advantages of silicone foam insulation, highlighting its unique capabilities and why it surpasses traditional materials. By understanding its benefits, we can explore its critical role in enhancing NEV battery performance, safety, and longevity.
Excellent Resilience:
Silicone foam insulation boasts exceptional resilience, making it an ideal choice for battery protection. Experimental data reveals that even after undergoing 8,000 cycles of compression, the material experiences minimal deformation, with less than 5% change. This outstanding rebound property ensures long-term effectiveness and reliability, safeguarding NEV batteries throughout their operational lifespan.
Comprehensive Prtection:
Silicone foam insulation provides more than just insulation. It offers additional advantages, including dustproofing, waterproofing, heat dissipation, and shock absorption. These properties are pivotal for NEV battery protection systems, shielding the battery pack from external contaminants, preventing moisture ingress, efficiently managing heat generated during operation, and minimizing the impact of vibrations and shocks. Such comprehensive protection contributes to the overall performance, safety, and durability of NEV batteries.
Unyielding Performance under Extreme Conditions:
Silicone foam insulation undergoes rigorous testing to evaluate its performance under harsh environmental conditions. Experimental data from stress relaxation tests conducted at 85°C and 85% relative humidity for 1,000 hours demonstrates that the material exhibits a stress relaxation rate of only 20.98%. This exceptional result attests to its ability to maintain mechanical integrity and provide consistent performance, even in demanding situations. NEV batteries can rely on silicone foam insulation to deliver unwavering protection, regardless of challenging operating conditions.
Superior Compression Resistance:
Silicone foam insulation has excellent resistance to crushing and retains its shape and performance even after extensive use. The material exhibits a consistently low compression set, ranging from 0.34% to 0.72% in a 10,000-belt 1 million compression cycle test, ensuring its long-lasting durability and effectiveness in protecting new energy vehicle batteries.
These results highlight the material's resilience and ability to maintain its shape and performance, even after prolonged use. NEV batteries benefit from the long-lasting durability provided by silicone foam insulation.
Minimal Water Absorption:
Silicone foam insulation exhibits an impressively low water absorption rate of only 0.266%. This characteristic is crucial in NEV battery protection, as it ensures the material remains stable and unaffected by moisture. The low water absorption rate prevents any adverse effects on the battery pack's performance, even in humid environments. It further reinforces the material's suitability for NEV applications.
As the NEV industry continues to advance, silicone foam insulation emerges as the optimal choice for battery protection and thermal management systems. Its exceptional resilience, comprehensive protection features, unyielding performance under extreme conditions, superior compression resistance, and minimal water absorption set it apart from traditional materials. Silicone foam insulation plays a pivotal role in enhancing NEV battery performance, safety, and longevity. Its numerous advantages make it a compelling solution that should be widely adopted in the NEV industry, driving innovation and ensuring the continued success of new energy vehicles.
