Battery Charge & Discharge Test Chamber QualiBCDT™ Series

Main Application of Battery Test Chamber

The explosion-proof battery charge and discharge test chamber is widely used in battery manufacturing, research and development, quality inspection, and safety evaluation. It is especially critical for verifying the safety of lithium-ion batteries used in electric vehicles, energy storage systems, and consumer electronics.

Its key test applications include:

• Charge and discharge operation: Simulates real usage conditions by charging and discharging batteries to accurately assess performance.
• Overcharge and over-discharge tests: Ensures safe evaluation by conducting extreme charging and discharging scenarios in an explosion-proof chamber, protecting the testing process even if battery failure occurs.
• Short-circuit protection performance: Simulates short-circuit conditions to verify the effectiveness of the battery’s protection mechanism and analyze its response.

In addition, the chamber performs reliability assessments such as cycle life and storage life tests, helping determine battery durability, safety, and overall service life under varying conditions.

The Test Standards of Battery test Chamber

The charge and discharge explosion-proof battery test chamber performs reliability assessments such as cycle life and storage life testing. These tests measure battery durability under different conditions to determine overall service life and safety.

Key applicable standards include:

• IEC 60086-4: Safety standard for lithium batteries, covering altitude simulation, thermal cycling, external short circuit, and thermal abuse tests.
• SAE J2464: Guidelines for safety and abuse testing of rechargeable energy storage systems in EVs and HEVs, including thermal stability and temperature cycling.
• IEC 62233: Workplace electrical safety standard specifying requirements for explosion-protected equipment, including batteries in hazardous areas.
• UL 913: Safety standard for intrinsically safe apparatus in Class I, Division 1 hazardous locations.

The three-layer explosion-proof test chamber also complies with EN 60079, IEC 62233, SAE J2929, UN/DOT 38.3, IEC 62133, and IEC 62660-2 standards.

Control System of the Test Chambers

The control system of the test chamber is built with advanced software and hardware to maintain operation under preset conditions, deliver accurate test data, and provide precise control and monitoring of experimental parameters.

• Controller: Features a high-performance control unit with an in-house developed system, optional Siemens integration, and connectivity through RS232, RS485, and Ethernet ports.
• Programmable control: Supports creating test programs such as heating, cooling, and constant temperature cycles. Multiple program settings can be executed, and tests can be scheduled in advance.
• Language options: Available in English and others.
• Remote monitoring: Network-based remote control allows real-time monitoring and data access via PC or mobile devices for added convenience.

Refrigeration System of the Test Chamber

The refrigeration system of the test chamber plays a critical role in ensuring test accuracy and reliability.

• Hot gas defrosting: Uses high-temperature, high-pressure refrigerant steam to prevent evaporator frost buildup, improving efficiency and reducing energy consumption.
• High-quality components: Built with internationally recognized refrigeration units. Durable solenoid valves with a service life of over 15 years were developed. Work has also begun on integrating Danfoss AKV electronic expansion valves for greater efficiency, energy savings, and reduced noise.
• Optimized design: The system layout incorporates VRF (variable refrigerant flow) technology with PID-based cold-end control, enabling energy savings of up to 30% under low-temperature operation.
• Modular system: Features low failure rates, minimal welding points, high efficiency, and simple, cost-effective maintenance.
