Reverse Polarity & Forced Failure Tester Prevent Thermal Runaway in 4S Battery Packs
Purpose: Simulates catastrophic risks when 1 cell is reversed in 4S cylindrical packs — critical for EV/ESS safety validation.
| Feature | Industry Standard | Our Innovation |
|---|---|---|
| Resistance Control | ≤0.5Ω | ≤0.1Ω ±0.01Ω |
| Safety Monitoring | Manual checks | AI thermal alerts at 55°C |
| Test Efficiency | 72h | 24h with auto-termination |
Step 1: Configuration - 4 identical new cells (same brand/model/batch) in series； - Cell B1 polarity reversed** (anode-cathode inversion)； **Step 2: Stress Application - Continuous circuit activation for 24 hours or until case temperature stabilizes at ambient； - Circuit resistance ≤0.1Ω (precision busbar connections)； Step 3: Failure Criteria ✅ PASS: Voltage fluctuation ≤5% · Temperature ≤60°C； ❌ FAIL: Explosion/fire/smoke/electrolyte leakage/vent deformation； | Parameter | Specification |
