Frequently Asked Questions
1. What is the difference between FISC and standard crush tests?
The FISC test (JIS C 8714/IEC 62133) simulates internal short circuits caused by manufacturing impurities (like nickel chips) under controlled temperatures. Unlike external crush tests which simulate severe impact, FISC requires ultra-high pressure accuracy (0.1N level) to reproduce specific internal failure points.
2. How does the tester determine the "end of test" point?
In accordance with JIS C 8714, the equipment monitors voltage in real-time. When a voltage drop (typically 50mV) is detected, the high-frequency acquisition system triggers the servo motor to stop applying pressure within milliseconds to preserve the test state.
3. How is pressure precision maintained during slow compression?
We use high-precision AC servo motors and ball screws to achieve smooth operation at speeds as low as 0.1mm/s. High-precision load sensors ensure pressure fluctuations stay within ±0.5%, avoiding the "crawling" effect found in low-end hydraulic systems.
4. Which international standards does this equipment comply with?
The tester is fully compliant with JIS C 8714, IEC 62133-2, and UN 38.3 standards for battery safety testing.
5. What safety features protect against thermal runaway?
Safety is ensured through a reinforced explosion-proof chamber, automatic smoke exhaust linked to detectors, emergency pressure relief doors, and dedicated ports for nitrogen or CO2 fire extinguishing systems.
6. Can the system generate professional test reports?
Yes, the integrated software allows for one-click generation of PDF or Excel reports that include visualized pressure-time and voltage-displacement curves, formatted specifically for IEC/JIS compliance.
