Working Principle
The machine uses a propane-fueled burner to generate controlled flames, which are directed at battery samples. A PLC system adjusts flame height and duration, while sensors monitor real-time temperature, voltage, and gas emissions. The test chamber is equipped with exhaust vents to manage fumes and maintain operator safety.
Test Principle
- Setup: Fully charged batteries are secured on a mesh platform in the chamber.
- Combustion Execution: The burner is ignited, and flames are adjusted to a set height (e.g., 38.1mm above the sample) to simulate thermal stress.
- Post-Test Analysis: Batteries are assessed for structural damage, leaks, and toxic gas emissions. Thermal imaging and gas chromatography data validate compliance with safety thresholds.
Key Advantages
- Versatility: Suitable for lithium-ion, NiMH, and lead-acid chemistries.
- Precision: Advanced sensors ensure accurate measurement of thermal events.
- Safety: Enclosed chamber with auto-extinguish features and emergency vents.
This machine empowers manufacturers to mitigate thermal-related risks, ensuring batteries meet stringent safety standards and reducing field failures.
