Product Description

Battery External Short Circuit Tester - China Manufacturer & Supplier

BONAD's Battery External Short Circuit Tester is essential safety equipment designed to rigorously simulate accidental short circuits across lithium-ion cell or battery terminals by connecting them through a precisely calibrated external resistor. This test critically evaluates if the battery experiences hazardous events – such as venting, rupture, thermal runaway, fire, or explosion – under extreme short-circuit conditions. As a leading China-based manufacturer, BONAD offers customizable testers in various sizes and configurations to meet diverse battery specifications, including 18650 cells, prismatic cells, and battery packs.

Compliant Test Standards

Our External Short Circuit Testers are engineered to meet the stringent requirements of major international safety and performance standards for lithium-ion batteries, including:

    UN Transportation: UN 38.3
    International Electrotechnical Commission (IEC): IEC 62133, IEC 62660-2, IEC 62660-3, IEC 62619
    European Standards: EN 50604-1, ECE R100
    Automotive: ISO 12405
    Automotive & Energy Storage: SAE J2464, J2929
    Safety Certification (UL): UL 2580

Applications

The BONAD External Short Circuit Tester is a critical apparatus for:

    1. Assessing the safety performance of lithium-ion cells and batteries under electrical abuse conditions.
    2. Evaluating the effectiveness of internal or external overcurrent protection devices (fuses, CID, PCM).
    3. Quality control and safety validation for battery manufacturers (cells & packs).
    4. Research and development of safer battery technologies.
    5. Certification testing according to UN, IEC, UL, and other international standards.
    6. Testing diverse battery formats: 18650, 21700, prismatic/pouch cells, and battery modules/packs.

Key Features & Advantages

1. Robust Safety Construction:

    Explosion-Proof Design: Outer box crafted from cold-rolled steel with anti-rust baking paint; reinforced stainless steel inner chamber with pressure relief port and explosion-proof chains.
    Visible Monitoring: Large explosion-proof glass window with internal lighting for safe, real-time observation.
    Integrated Safety Systems: Smoke exhaust port, multiple safety protections (grounding, over-current, leakage, short-circuit, over-temperature).
2. Precision Testing & Control:

    Programmable Resistance: Meets standard resistances (e.g., (80±20) mΩ, ≤100 mΩ, (20±10) mΩ, (30±10) mΩ, ≤5 mΩ) or fully customizable to your specific requirement.
    PLC & Touch Screen Control: Centralized control via intuitive HD touch screen. Set parameters (short-circuit duration, temp limits), monitor real-time data (voltage, current, case temp, peak temp), and choose manual/auto test modes.
    Intelligent Test Logic: PLC monitors temperature rise drop ratio and triggers automatic termination based on pre-set conditions.
3. Advanced Functionality:

    Temperature Control: Built-in heating and air convection system for ambient temperature testing (standards often require 55°C±2°C).
    Comprehensive Data Handling: Automatic test data recording, storage, and export capabilities.
    Wireless Remote Operation: Enhance operator safety with remote test initiation.
    Versatile Fixturing: Dedicated holders/clamps for various battery types (cylindrical, prismatic, packs).
4. User-Centric Design:

    Vertical Test Chamber: Upper test area placement for easy sample access and operation.
    Mobility: Equipped with lockable casters for convenient movement and positioning.
    Integrated Components: Features built-in short-circuit clamps, resistance cables, and temperature sensors (battery surface & chamber).

Test Principle

The sample battery inside the temperature-controlled chamber is securely connected via clamps to the tester's circuit. Upon initiating the test (remotely or via touch screen), a high-capacity contactor closes, creating a direct short circuit through the precisely calibrated external resistor. This generates the maximum possible short-circuit current. The PLC continuously acquires critical data (battery voltage, current, surface temperature) via sensors. This real-time feedback allows the PLC to intelligently control the test duration, monitor safety thresholds, and terminate the test based on pre-configured conditions (time, temperature drop, etc.), while observing for any safety failures.
