Yuelian PW-6003C Battery Short-Circuit Testing Chamber

Overview

The Yuelian PW-6003C Battery Short-Circuit Testing Chamber is a purpose-built environmental test chamber engineered to evaluate thermal and electrical safety performance of lithium-ion batteries, cylindrical/prismatic cells, pouch cells, and battery modules under controlled short-circuit conditions. It operates on the principle of forced-air convection heating combined with integrated high-current DC short-circuit circuitry (capable of delivering up to 1000 A peak current, depending on external power supply configuration), enabling standardized simulation of internal or external short-circuit events per IEC 62133, UN 38.3, GB/T 31241, and UL 1642 test protocols. Unlike general-purpose ovens, the PW-6003C integrates real-time voltage/current monitoring interfaces, emergency power cutoff relays, and explosion-resistant construction features—including reinforced tempered glass viewing window and pressure-relief venting—making it suitable for compliance-driven battery safety validation in R&D labs, QC departments, and third-party certification facilities.

Key Features

• Robust chamber construction: Interior chamber walls fabricated from 1.2 mm thick 304 stainless steel mirror-finish panels; exterior housing made of 1.2 mm cold-rolled steel with powder-coated off-white finish.
• Precision temperature control: Equipped with PID-based digital temperature controller supporting operation range from ambient +10°C to 200°C, with ±1.5°C uniformity and ±0.5°C stability over time.
• Optimized thermal insulation: 100 mm thick high-density glass fiber rock wool insulation ensures low heat loss and stable thermal profiles during prolonged testing cycles.
• Enhanced operator safety: Dual 50 mm diameter cable access ports (left/right side) with silicone grommets; heavy-duty casters with locking brakes for stable positioning; reinforced observation window (250 × 350 mm) using heat-resistant tempered glass.
• Modular interior layout: Two adjustable stainless-steel wire mesh shelves included; interior dimensions 500 W × 500 D × 600 H mm (19.7″ × 19.7″ × 23.6″); overall footprint approx. 770 W × 720 D × 1370 H mm (30.3″ × 28.3″ × 53.9″).

Sample Compatibility & Compliance

The PW-6003C accommodates standard cell formats including 18650, 21700, 26650, prismatic (up to 200 mm × 150 mm × 50 mm), and flexible pouch cells. Its design supports both open-circuit thermal soak and active short-circuit testing when interfaced with external programmable DC loads or short-circuit switches. The chamber meets structural and operational requirements referenced in IEC 62133-2:2017 Clause 8.3 (Abnormal Charging and Forced Discharge), UN Manual of Tests and Criteria Part III, Subsection 38.3, Section 38.3.2 (External Short Circuit), and GB/T 31241–2014 Section 7.7. All mechanical and electrical interfaces are designed to facilitate integration into GLP- and GMP-aligned test workflows, including traceable calibration records and documented maintenance logs.

Software & Data Management

While the PW-6003C operates as a standalone hardware platform, its analog voltage/current output terminals (0–5 V or 4–20 mA) and RS485 Modbus RTU interface enable seamless integration with external data acquisition systems (e.g., National Instruments DAQ, Keysight DAQ970A) or LIMS platforms. Users may configure automated logging of temperature, voltage drop across test samples, and elapsed time during short-circuit events. Optional firmware upgrades support timestamped event triggering and audit-trail generation compliant with FDA 21 CFR Part 11 requirements when paired with validated software environments.

Applications

• Validation of battery cell response to external short-circuit under elevated temperature (e.g., 60°C or 75°C preconditioning per UN 38.3)
• Thermal runaway propagation studies in multi-cell modules
• Pre-compliance screening for OEM battery qualification programs
• Material-level evaluation of separator shutdown behavior and electrolyte decomposition onset
• Supporting root cause analysis in failure investigation laboratories

FAQ

Does the PW-6003C include built-in short-circuit switching hardware?

No—the chamber provides mounting provisions, cooling pathways, and electrical feedthroughs optimized for integration with externally supplied high-current short-circuit switches or programmable electronic loads. This modular approach ensures flexibility across varying test current requirements.

Is the chamber suitable for testing large-format EV battery modules?

The internal volume supports single-module testing up to ~200 mm × 150 mm × 50 mm. For larger assemblies, custom chamber variants with expanded dimensions are available upon engineering consultation.

What calibration documentation is provided?

Each unit ships with a factory calibration certificate covering temperature uniformity and controller accuracy at three setpoints (room temperature, 60°C, and 120°C), traceable to NIM (China National Institute of Metrology) standards.

Can the chamber be operated in inert atmosphere environments?

Standard configuration does not include gas purge capability. However, optional nitrogen purge fittings and O₂ sensor integration can be added during order specification for controlled-atmosphere testing.
