Preventing thermal propagation in batteries is crucial for ensuring the safety of electric vehicles and energy storage systems. At Aerospace & Advanced Composites GmbH (AAC), we provide a cost-efficient and highly realistic testing method that evaluates battery insulation materials under thermal propagation events. This approach is significantly faster and more affordable than full thermal runaway testing, allowing manufacturers to refine materials early and enhance overall battery safety.
A Smarter Approach to Thermal Propagation Testing
Our advanced radiant heater system rapidly exposes materials to extreme heat, simulating real-world conditions within minutes. Instead of using actual battery cells in thermal runaway, we apply radiant heaters to ensure controlled and repeatable test conditions. This eliminates risks while providing precise insights into material performance. By focusing on sub-element testing, we optimize materials early, reducing the need for costly full-module evaluations.
Key Benefits of Our Testing Method:
• Materials Screening: Allows efficient screening of candidate materials
• Faster Results: Provides insights within minutes instead of hours or days.
• Lower Costs: Eliminates the need for expensive full battery pack tests.
• Controlled & Repeatable: Radiant heaters ensure precise and safe testing conditions.
• Comprehensive Analysis: Combines thermal and mechanical stress testing for realistic assessments.
• Advanced Monitoring: Uses cameras and temperature sensor arrays for accurate data collection.
Driving Battery Safety Forward
By simulating thermal propagation events in a controlled and efficient manner, our testing method improves fire safety, extends battery lifespan, and enhances design flexibility. The insights gained help manufacturers develop safer, high-performance battery technologies, driving innovation in energy storage and electric mobility.
Conclusion
AAC’s cost-effective, high-speed testing approach provides reliable, real-world insights into battery insulation materials. With a faster, safer, and more precise evaluation process, we accelerate the development of next-generation battery safety solutions.
