Temperature Controlled Battery Short Circuit Test Chamber

Product Overview

This temperature-controlled battery short circuit test chamber is an integrated high-current safety evaluation system for reproducing controlled battery short-circuit events. It combines a pneumatic contactor, temperature-control chamber, remote controller, PLC touchscreen interface, and measurement capability in one purpose-built test platform. With a maximum short-circuit current of 400A and device internal resistance of 80±20mΩ at 400A load current, the equipment is configured to support demanding maximum-current short-circuit evaluations.

The system is intended for battery safety verification where electrical fault conditions must be assessed at controlled chamber temperatures. It is suited to battery R&D laboratories, cell and pack qualification teams, industrial test centers, and organizations working against GB, IEC, EN, UN38.3, UL, MT/T 1051-2007, and GB/T 2900.11-1988 requirements referenced for this type of test. Voltage, current, and two-channel temperature acquisition support direct observation of critical test variables.

Reliability is built into both the control architecture and the physical test enclosure. PLC touchscreen operation supports clear, automated control, while PID plus SSR heating, forced horizontal air circulation, rapid temperature compensation, over-temperature protection, automatic overload shutdown, reinforced access hardware, protected viewing, smoke extraction, and mobile locking casters support consistent operation under severe battery fault-test conditions.

Key Features

• High-Current Short-Circuit Capability: The equipment delivers a maximum short-circuit current of 400A. Its 80±20mΩ internal resistance at 400A load current is substantially below the 100mΩ threshold cited in the applicable short-circuit test requirements, helping the test circuit achieve the required maximum fault current.

• PLC Touchscreen Automation: A PLC touchscreen provides direct, intuitive control of the test sequence and chamber settings. This interface supports automatic constant-temperature operation and gives laboratory personnel a centralized operating point for routine safety-test workflows.

• Controlled Thermal Test Environment: The adjustable chamber operating range is RT~80℃, with temperature fluctuation of ±0.5℃ and temperature deviation of ±2℃. PID plus SSR heating and rapid temperature-compensation functionality help the unit respond to changing thermal conditions during controlled testing.

• Integrated Electrical Measurement: The system measures 010V voltage with ±0.2%F.S accuracy and 0400A DC current with ±0.5%F.S accuracy. Each electrical channel is acquired at 100ms, enabling synchronized monitoring of the applied short-circuit condition.

• Two-Channel Temperature Acquisition: Temperature measurement covers 0℃~500℃ with 1.5℃ accuracy and 100ms acquisition speed across two channels. This supports observation of thermal response alongside current and voltage data during battery fault evaluation.

• Forced Horizontal Air Circulation: A high-temperature long-shaft motor drives a forced horizontal air-delivery circulation system. The airflow arrangement works with the heating system to maintain the chamber environment during temperature-controlled testing.

• Layered Safety Protection: The unit incorporates over-temperature protection and automatic overload power cutoff. A timer function provides power-disconnection alarm indication when the temperature reaches the set time, adding a defined response point to the test operation.

• Reinforced Observation and Containment: The front door uses exposed reinforced hinges and a heavy-duty locking clasp to secure the enclosure. The explosion-proof glass viewing window is protected by explosion-proof film and an added steel safety mesh, while externally mounted lighting reflects into the inner chamber for visible inspection without placing the lamp inside the test area.

• Smoke Extraction and Service Access: A top-mounted blower extracts smoke from the test area through a rear-extending 100mm-diameter exhaust pipe. One 50mm test port on each side of the enclosure supports test connections and may also be used for voltage measurement.

• Mobile Industrial Enclosure: The painted cold-rolled steel cabinet is fitted with four universal casters and locking foot cups. This arrangement allows the equipment to be moved into position and then fixed securely for operation.

Why Choose This Product

• Purpose-Built Electrical Fault Testing: This system integrates the contactor, controlled enclosure, remote operation, measurement ranges, and protective structure required for high-current battery short-circuit work. Buyers gain a dedicated test asset rather than assembling separate components around a temporary fixture.

• Stable, Measurable Conditions: The combination of adjustable RT~80℃ chamber control, ±0.5℃ temperature fluctuation, PID plus SSR heating, forced circulation, and 100ms acquisition supports disciplined, repeatable laboratory procedures. Electrical and thermal parameters can be monitored within the stated ranges during the same test event.

• Robust Containment Design: Reinforced door hardware, a protected observation window, external lighting, over-temperature protection, overload cutoff, and top smoke extraction address the practical demands of battery abuse testing. These design elements support daily laboratory operation where clear observation and enclosure integrity are essential.

• Operational Flexibility: The remote controller operates up to 7m without solid obstruction, side test ports support connections and voltage measurement, and lockable universal casters simplify positioning within a test area. The equipment can be placed, secured, connected, and observed with practical laboratory access in mind.

• Long-Term Laboratory Value: A 300,000-cycle mechanical life, SUS304 inner test chamber, high-temperature long-shaft motor, and painted cold-rolled steel enclosure reflect an engineering focus on durable service in recurring test programs. The configuration supports battery research, safety qualification, and quality investigations across cell, module, and pack workflows.
