CZGY DCX-150 Battery Environmental Test Chamber

Overview

The CZGY DCX-150 Battery Environmental Test Chamber is a purpose-engineered temperature-controlled enclosure designed specifically for electrochemical stability assessment, cycle life validation, and safety evaluation of lithium-ion, NiMH, and emerging solid-state battery cells and modules under controlled thermal conditions. Unlike general-purpose incubators, the DCX-150 integrates dual-mode thermoregulation—precision Peltier-assisted cooling and resistive heating—with forced-air convection architecture to maintain stable, reproducible thermal environments across its 150 L working volume. Its operational range of 5–50 °C aligns with IEC 62133, UN 38.3, and GB/T 31485 test protocols requiring ambient-to-moderate elevated temperature exposure. The chamber’s structural design prioritizes thermal integrity: 304 stainless steel interior surfaces resist corrosion from electrolyte outgassing, while high-density rock wool insulation minimizes thermal bridging and external heat load interference—critical for long-duration tests (>72 h) where drift must remain within ±0.5 °C.

Key Features

• Dual-mode temperature control system enabling seamless transition between active cooling and heating without mechanical relay cycling—reducing thermal overshoot and extending component service life.
• Forced-air circulation with optimized inlet/outlet duct geometry ensures uniform airflow distribution, achieving ±1 °C spatial uniformity across the full chamber volume per ISO 17025-compliant validation methodology.
• Large-format backlit LCD interface with intuitive menu navigation supports real-time monitoring of setpoint, actual temperature, elapsed time, and timer status—designed for integration into GLP-compliant laboratory workflows.
• Single 50 mm diameter access port located on the left side allows unobstructed routing of voltage/current leads, thermocouple wires, or gas sampling lines without compromising chamber seal integrity.
• Five independently adjustable 304 stainless steel trays accommodate heterogeneous cell formats (pouch, cylindrical, prismatic) while permitting vertical airflow penetration for consistent thermal exposure.
• Powder-coated cold-rolled steel exterior provides mechanical durability and resistance to incidental chemical splashes common in battery testing laboratories.

Sample Compatibility & Compliance

The DCX-150 accommodates standard battery test configurations including single-cell fixtures, multi-cell test racks, and small-format module assemblies up to 400 mm in height. Its interior dimensions (450 × 450 × 750 mm) support stacking arrangements compliant with UL 1642 thermal runaway propagation studies when used in conjunction with external fire detection and suppression systems. The chamber meets structural and operational requirements referenced in ASTM F2455 (Standard Practice for Evaluating Lithium Battery Safety), IEC 62660-2 (Secondary lithium-ion cells for electric propulsion), and CNAS-CL01:2018 accredited calibration traceability frameworks. All temperature logging data—including timestamps, setpoints, and deviations—is exportable via USB for audit-ready record retention aligned with FDA 21 CFR Part 11 electronic record principles.

Software & Data Management

While the DCX-150 operates as a standalone instrument with embedded microcontroller-based regulation, its analog output (0–5 V or 4–20 mA) enables connection to third-party data acquisition systems such as LabVIEW, MATLAB, or custom SCADA platforms. Optional RS-485 Modbus RTU communication (available upon request) permits remote parameter setting, real-time temperature streaming, and event-triggered alarms—facilitating synchronized operation with battery cyclers (e.g., Arbin, Bitrode) and environmental monitoring networks. Internal non-volatile memory retains user-defined profiles and last-known operating state after power interruption, minimizing procedural restart overhead during extended qualification runs.

Applications

• Accelerated aging studies per IEEE 1188 guidelines to model capacity fade mechanisms at elevated temperatures (e.g., 45 °C @ 100% SOC).
• Low-temperature performance characterization down to 5 °C for low-temperature LiFePO₄ and LTO chemistries.
• Thermal preconditioning prior to mechanical abuse testing (crush, nail penetration) per UN 38.3 Section 38.3.4.
• Electrolyte volatility screening through controlled isothermal holds combined with headspace GC-MS sampling via the left-side port.
• Validation of battery management system (BMS) thermal feedback loops using externally injected temperature signals.

FAQ

Does the DCX-150 support humidity control?
No—this model is strictly a temperature-only chamber. For combined temp/humidity testing, consider the CZGY DHX series.
Can the access port be customized for multiple feedthroughs?
Yes—custom port configurations (e.g., dual 30 mm ports or PG13.5 gland fittings) are available under OEM engineering support.
Is NIST-traceable calibration documentation included?
A factory calibration certificate (±0.3 °C at 25 °C) is supplied; full ISO/IEC 17025 calibration with uncertainty budget requires separate service engagement.
What is the maximum continuous operating time?
Rated for uninterrupted operation up to 168 hours (7 days) under nominal load conditions (25 °C setpoint, ambient ≤30 °C).
Are replacement trays and insulation kits available?
Yes—genuine CZGY spare parts (trays P/N: DCX-T-304-5, insulation kit P/N: DCX-INS-RW-150) are stocked for global dispatch.
