UN 38.3 Battery External Short Circuit Tester

Brand: SZBONAD

Product Number: BND-BEST

BONAD’s UN 38.3 Battery External Short Circuit Tester simulates accidental electrical connections between battery terminals to evaluate safety risks. As a leading China-based manufacturer and supplier, we engineer this critical apparatus to test lithium-ion cells/batteries (e.g., 18650, prismatic, packs) for hazards like venting, rupture, thermal runaway, fire, or explosion. The tester applies a controlled short circuit via an external resistor, replicating real-world failure scenarios to ensure compliance with global safety standards.

Applications:

Ideal for R&D, quality control, and certification labs:

  • Safety validation of lithium-ion/secondary batteries.
  • Overcurrent protection device performance testing.
  • Abuse testing for cells (18650, pouch, cylindrical) and battery packs.
  • Compliance checks for electric vehicles (EV), energy storage systems (ESS), and consumer electronics.

Features:

1. Safety & Durability

  • Explosion-Proof Design: Reinforced stainless steel inner chamber withstands explosions without deformation.
  • Pressure Relief & Smoke Extraction: Built-in vents and exhaust ports manage hazardous events.
  • Multi-Layer Protection: Explosion-proof chains, tempered glass window with lighting, and safety mechanisms (over-current, leakage, short-circuit, and over-temperature protection).

2. Precision Control

  • PLC & Touch Screen Interface: Set parameters (resistance, duration, temperature thresholds) via HD touch panel.
  • Real-Time Monitoring: Track voltage, current, battery surface temperature, and peak values during tests.
  • Adjustable Resistance: Supports resistors from ≤5 mΩ to (80±20) mΩ (customizable to requirements).

3. User-Centric Design

  • Vertical Test Chamber: Upper test area with ergonomic clamps and cable access.
  • Temperature Control: Integrated heating, air convection, and temperature sensors (-40°C to 150°C range).
  • Mobility & Customization: Wheel casters for portability; holders for diverse battery types (packs, cells).

4. Advanced Data Management

  • Automated data logging, storage, and export for compliance reports.
  • Wireless remote control and dual test modes (manual/automatic).
