Thermal Abuse Test Chamber for Lithium Battery Safety Testing

Product Overview

This thermal abuse test chamber is engineered for furnace heating and controlled heating tests during lithium battery safety evaluation. It provides a defined test environment for 3C single cells and 3C battery packs below 10 Ah, combining programmable temperature control, forced horizontal airflow, timed operation, and smoke extraction in one reinforced enclosure. The system is designed to help laboratories conduct repeatable thermal exposure tests while maintaining clear visibility and straightforward operator control.

Typical users include battery research laboratories, consumer electronics manufacturers, battery pack developers, quality assurance teams, and safety certification facilities. The equipment supports evaluations associated with UL 1642, UL 2054, IEC 62133-2012, IEC 62660, and IEC 62619 test requirements. Its stainless-steel test area, reinforced access door, durable insulation, and automatic protection functions provide dependable operation when samples are exposed to elevated temperatures under controlled conditions.

Key Features

• Programmable PLC Touchscreen Control: The PLC-based touchscreen interface provides direct access to temperature, timing, and operating functions. Automatic constant-temperature control and rapid temperature compensation simplify setup and improve test repeatability.

• Controlled Thermal Exposure: The unit operates from RT+10 to +150°C with a selectable heating rate of 5°C ±2°C per minute from RT+10 to 150°C. Linear ramp settings support controlled execution of battery safety procedures.

• High-Accuracy PID Regulation: Microcomputer PID control continuously displays PV and SV values and automatically calculates suitable control parameters. The system provides temperature accuracy of ±0.5°C and an empty-chamber temperature deviation of ±2.0°C.

• Forced Horizontal Airflow: A horizontal air circulation design promotes even heat distribution throughout the test area. The extended-shaft stainless-steel circulation motor and high- and low-temperature-resistant aluminum multi-wing fan are engineered for sustained laboratory use.

• Integrated Smoke Exhaust: A top-mounted blower removes smoke from the test area through a rear exhaust pipe with a 100 mm diameter. This dedicated exhaust arrangement supports controlled handling of emissions generated during thermal abuse testing.

• Reinforced Safety Door: The front door uses heavy-duty construction, an exposed external hinge, and a strong locking mechanism to secure the test area. A 5 mm steel reinforcement plate behind the lock area provides a one-way load capacity of at least 20 kN.

• Automatic Protection Functions: Over-temperature protection and overload-triggered automatic power interruption reduce equipment risk during abnormal operating conditions. When the programmed test time is reached, the unit disconnects power and activates an alarm indication.

• Low-Contamination Interior: The SUS304 mirror-finish stainless-steel chamber is clean, smooth, corrosion-resistant, and easy to wipe down. Internal components use low-pollution materials, while the inner chamber is assembled with seamless argon-arc welding to reduce residue-collecting surfaces.

• Durable Thermal Insulation: A 100 mm insulation layer uses fire-resistant, high-strength PU foam insulation material. Its insulation coefficient is below 0.0212 kcal/m·hr, helping limit heat loss and maintain stable chamber conditions.

• Mobile Industrial Structure: Four bottom casters allow the equipment to be repositioned and fixed as required. The welded base uses 45# channel steel with a 6 mm thickness, supporting a stable frame for repeated testing.

Applications

Technical Specifications

The chamber supports the principal heating profiles specified in the referenced battery safety standards. Under UL 1642 and UL 2054 procedures, the sample is heated in a natural-convection or forced-convection oven at 5 ±2°C per minute to 150°C, then held for 10 minutes before the test is stopped. The relevant acceptance requirement is that the sample does not catch fire or explode.

For IEC 62133-2012 testing, each fully charged single cell is placed in a natural-convection or forced-ventilation oven. The temperature rises at 5°C/min ±2°C/min to 130°C ±2°C, and the cell remains at that temperature for 10 minutes before the test ends. The acceptance requirement is also no fire and no explosion. Actual test planning, sample preparation, instrumentation, and facility safety procedures should follow the applicable standard and the user's approved laboratory protocol.

Why Choose This Product
