Features

High-Strength Stainless Steel Vessel

304 stainless steel chamber ensures corrosion resistance, high-temperature durability, and mechanical integrity. Design pressure 3 MPa, constant operating pressure 2.5 MPa, with a safety valve for rapid pressure relief.

Multi-Channel Battery Parameter Monitoring

Supports online monitoring of voltage, temperature, and pressure through K-type high-temperature thermocouples and high-precision imported sensors, covering heating, overcharge, and nail penetration trigger modes.

Integrated Environmental Control

Vacuum extraction, nitrogen filling, exhaust, and oxygen concentration detection (0–100% Vol.) are included. Video monitoring allows real-time observation of thermal runaway events.

Automated Gas Sampling System

Multi-layer sample lines with real-time pressure monitoring ensure continuous, accurate gas sampling. Automatic switching prevents blockage and maintains system integrity.

Heated Sampling Lines

Prevents intrusion of liquid electrolyte into analytical instruments, reducing interference and improving gas composition measurement accuracy.

Advanced Gas Analysis

FTIR spectrometer and electrochemical sensors, combined with a professional analysis model, enable precise online measurement of complex gases produced during battery thermal runaway.

User-Friendly Control Software

Intuitive interface, low latency, real-time monitoring of gas composition, battery parameters, and environmental conditions.

Extended Data Processing

Automatic calculation modules for gas evolution rate and total gas volume, with seamless integration into the software for data visualization and reporting.

Accessories

(1) Multi-layer gas sampling lines

(2) Pressure and temperature sensors

(3) Vacuum pump and nitrogen supply interface

(4) FTIR spectrometer

(5) Electrochemical gas sensors

(6) Heated pipeline assembly

(7) Video monitoring system

Test Procedures

Sample Installation: Place battery cells into the pressure vessel and secure the chamber.

System Setup: Connect nitrogen supply and configure oxygen concentration requirements.

Parameter Configuration: Set monitoring channels for voltage, temperature, pressure, and gas analysis in the control software.

Initiate Thermal Runaway: Trigger the battery using heating, overcharge, or nail penetration methods.

Data Acquisition: Real-time monitoring of gas composition, internal pressure, temperature, and battery parameters. Automated calculation of gas evolution rate and total gas volume.

Observation and Recording: Monitor test via video feed and software interface.

Test Completion: Safely vent the vessel, retrieve battery cells, and store collected data for analysis and reporting.

Maintenance Information

Inspect vessel seals, flanges, and sampling connections regularly for integrity.

Calibrate temperature, pressure, and gas sensors periodically.

Clean sampling lines and FTIR components to prevent contamination and measurement errors.

Verify nitrogen supply, vacuum pump operation, and safety valve function before each test.

Backup all acquired test data and system logs for traceability and reporting purposes.
