Working Principle
The machine uses pneumatic actuators to drive a hardened steel needle vertically through the battery, creating an internal short circuit. Sensors monitor voltage drop, surface temperature, and pressure changes in real time. A PLC system controls penetration depth and data logging, while a remote control panel ensures operator safety.
Test Principle
- Setup: Fully charged batteries are secured in the test chamber.
- Penetration Execution: The needle pierces the battery at a controlled speed, simulating a short circuit.
- Post-Test Analysis: Batteries are observed for fire, smoke, or structural failure. Voltage and temperature data validate compliance with safety thresholds.
Key Advantages
- Versatility: Supports lithium-ion, NiMH, and lead-acid chemistries.
- Customization: Adjustable needle size and penetration speed for diverse test requirements.
- Safety: Enclosed chamber with auto-extinguish features and emergency vents.
This machine empowers manufacturers to identify mechanical vulnerabilities, ensuring batteries meet stringent safety standards and reducing field failures.
