Working Principle

The machine uses high-current contactors to create an external short circuit, forcing the battery’s chemical energy to convert rapidly into heat. Sensors monitor real-time voltage, current, and temperature changes, while a PLC system controls the short-circuit duration and data logging. The chamber is equipped with exhaust vents to manage fumes and protect operators.

Test Principle

  1. Setup: Fully charged batteries are secured in the test chamber.
  2. Short-Circuit Execution: Contactors close to apply a low-resistance load (e.g., 0.1Ω), simulating extreme electrical stress.
  3. Post-Test Analysis: Batteries are inspected for structural damage, leaks, or thermal runaway. Data on voltage drop and temperature spikes validate compliance with safety thresholds.

Key Advantages

  • Versatility: Suitable for lithium-ion, NiMH, and lead-acid chemistries.
  • Precision: Advanced sensors ensure accurate measurement of electrical and thermal events.
  • Safety: Enclosed chamber with auto-extinguish features and emergency vents.

This machine empowers manufacturers to mitigate electrical risks, ensuring batteries meet stringent safety standards and reducing field failures.
