Jianhu JH-BT Series Programmable High-Low Temperature Aging Chamber for Batteries and Semiconductors

Overview

The Jianhu JH-BT Series Programmable High-Low Temperature Aging Chamber is an engineered environmental test system designed for accelerated life testing, thermal stress screening, and reliability validation of electrochemical energy storage devices and semiconductor components. Operating on the principle of controlled convective thermal cycling within a sealed, insulated chamber, the system delivers precise, repeatable temperature profiles across a wide operational range (–70 °C to +150 °C). Its architecture integrates dual-stage compressor refrigeration, high-efficiency heating elements, and a multi-point air circulation system to ensure thermodynamic stability and spatial uniformity—critical parameters for evaluating Arrhenius-driven degradation mechanisms in lithium-ion batteries and silicon-based ICs. The chamber complies with fundamental requirements outlined in IEC 60068-2-1 (Cold), IEC 60068-2-2 (Dry Heat), and JEDEC JESD22-A104 (Temperature Cycling), forming the physical foundation for qualification testing under MIL-STD-810G, AEC-Q200, and UN38.3 frameworks.

Key Features

• Explosion-proof certified construction (ATEX/IECEx-compliant enclosure options available), meeting Class I, Division 1 hazardous location requirements for volatile electrolyte testing.
• High-fidelity temperature control with ±0.5 °C fluctuation and ±2.0 °C uniformity across the working volume—validated per ISO 16750-4 Annex B procedures.
• Rapid thermal transition capability: ≤60 minutes for full-range heating (–40 °C → +85 °C); ≤45 minutes for full-range cooling (+85 °C → –40 °C), enabling efficient HALT/HASS protocols.
• Programmable multi-segment thermal profiles with up to 99 cycles, 999 steps, and user-defined ramp rates (0.1–10 °C/min), supporting complex aging sequences per IEEE 1625 and IPC-9701.
• Robust stainless-steel interior (SUS304), reinforced insulation (polyurethane foam, ≥150 mm thick), and corrosion-resistant structural frame for long-term operational integrity.
• Integrated real-time monitoring of chamber ambient conditions via calibrated PT100 sensors (traceable to NIST standards), with optional external sensor ports for DUT-level thermal feedback.

Sample Compatibility & Compliance

The JH-BT Series accommodates battery cells (cylindrical, prismatic, pouch), battery modules (up to 300 V DC bus), bare die, packaged ICs (QFN, BGA, CSP), and optoelectronic assemblies. Internal dimensions are configurable—from compact benchtop units (W300 × D300 × H300 mm) to large-volume walk-in configurations (W2000 × D1500 × H1800 mm)—with standardized cable ports, power feedthroughs (up to 600 V AC/DC), and gas purge interfaces (N₂, dry air). All models meet CE marking requirements under the EU Machinery Directive 2006/42/EC and Electromagnetic Compatibility Directive 2014/30/EU. Optional validation packages support IQ/OQ documentation aligned with ISO/IEC 17025 and FDA 21 CFR Part 11 data integrity expectations.

Software & Data Management

Control is executed via a 10.1″ capacitive touchscreen HMI running embedded Linux OS, featuring password-protected user roles (Operator, Engineer, Administrator), audit-trail logging (timestamped parameter changes, alarm events, manual overrides), and encrypted data export (CSV, PDF, XML). Optional PC-based software (Jianhu TestSuite™) enables remote supervision, multi-chamber synchronization, statistical process control (SPC) charting, and automated report generation compliant with GLP and GMP Annex 11. Raw thermal data is timestamped at 1 Hz resolution and stored onboard (≥12 months’ capacity), with optional cloud backup via TLS 1.2–secured MQTT protocol.

Applications

• Battery R&D: Cycle-life prediction under variable thermal loads; SEI growth analysis; thermal runaway propagation studies per UL 9540A.
• EV Battery Manufacturing: End-of-line formation verification, calendar aging simulation, and module-level thermal derating validation.
• Semiconductor Qualification: Burn-in screening of power MOSFETs, GaN HEMTs, and automotive MCUs per AEC-Q100 Grade 0–2 specifications.
• Photovoltaic Component Testing: Thermal cycling of PERC cells and encapsulant adhesion assessment per IEC 61215-2 MQT03.
• Medical Device Validation: Sterile packaging integrity testing under accelerated aging per ISO 11607-1 Annex A.

FAQ

What safety certifications does the JH-BT Series hold for use with lithium battery testing?
The standard configuration carries CE, RoHS, and CCC marks. Explosion-proof variants are certified to IEC 60079-0/-1/-7 for Group II C (hydrogen-class) atmospheres and include intrinsically safe signal conditioning for voltage/current monitoring during in-situ charge/discharge.
Can the chamber interface with external battery cyclers or data acquisition systems?
Yes—via isolated analog I/O (0–10 V, 4–20 mA), Modbus RTU over RS-485, and Ethernet TCP/IP. Digital trigger inputs support synchronized start/stop with commercial cycler platforms (e.g., Arbin, Bitrode, Neware).
Is temperature mapping and system suitability validation supported out of the box?
Each unit ships with a 9-point validation certificate (per ASTM E744). Optional IQ/OQ protocols—including 27-point thermal mapping, alarm response verification, and recovery time measurement—are available as add-on services performed by Jianhu’s ISO/IEC 17025-accredited field engineers.
What maintenance intervals are recommended for compressor-based refrigeration systems?
Compressor oil and filter replacement every 24 months; condenser coil cleaning quarterly; annual calibration of all PT100 sensors using traceable reference standards. Preventive maintenance kits and service contracts are available globally.
Does the system comply with FDA 21 CFR Part 11 for electronic records in regulated environments?
When equipped with Jianhu TestSuite™ and configured with role-based access control, digital signatures, and immutable audit trails, the system satisfies Part 11 requirements for closed systems. Full validation documentation (URS, FRS, DQ/IQ/OQ/PQ) is provided upon request.
