Lithium-ion Battery High-Low Impact Test Chamber, also known as a high-low temperature impact test chamber or thermal shock test chamber, is a device used to test the performance and reliability of lithium-ion batteries under temperature environments. This equipment controls and changes the internal environmental temperature through heating and cooling systems, simulating the required environmental temperature and alternating programs for the product, thereby testing the performance of lithium-ion batteries under rapid temperature changes.

Main Functions

Temperature Shock Testing: Capable of simulating rapid switching between high and low temperatures to evaluate the performance changes of lithium-ion batteries under temperature shock.

Performance Monitoring: During testing, parameters such as voltage, current, capacity, and internal resistance of the lithium-ion battery can be monitored in real-time to comprehensively evaluate its performance.

Safety Protection: Equipped with multiple safety protection devices, such as power overload protection, leakage protection, and over-temperature protection, ensuring the safety and reliability of the testing process.

Structural Features

Chamber Structure: Typically adopts a box-type structure, with the interior divided into high-temperature and low-temperature zones. The rapid movement of the test object between the high-temperature and low-temperature zones is achieved through devices like baskets or conveyor belts to complete the temperature shock test.

Material Selection: The inner chamber is often made of stainless steel, which offers excellent corrosion resistance and high-temperature performance. The outer chamber material is selected based on actual needs, such as spray-painted steel plates or stainless steel.

Control System: Utilizes a PLC and touchscreen intelligent control system with remote control functionality, making operation simple, stable, and reliable.

Technical Parameters

Temperature Range: The high-temperature zone can typically reach +60°C to +200°C, while the low-temperature zone can reach -55°C to -10°C or lower.

Heating/Cooling Time: Heating and cooling times vary depending on the specific model and configuration. Typically, heating time is less than 35 minutes, and cooling time ranges from less than 75 minutes to 90 minutes.

Shock Recovery Time: Recovery time after high and low-temperature shocks is usually short, such as within 5 minutes.

Application Areas

Lithium-ion Battery High-Low Impact Test Chamber is widely used in fields such as new energy vehicle power batteries, energy storage systems, and consumer electronics. By simulating usage conditions under different temperature environments, it can evaluate the performance changes of lithium-ion batteries under temperature shock, providing important references for product design, improvement, and optimization.

Selection Recommendations

Choose Based on Testing Needs: Select the appropriate test chamber model and configuration based on the type of lithium-ion battery, application scenarios, and testing requirements. For example, for tests requiring rapid heating and cooling, choose a test chamber with an efficient heating and cooling system.

Consider Chamber Performance: Select a test chamber with a high-precision temperature control system, stable and reliable control system, and multiple safety protection devices to ensure the accuracy and reliability of test results.

Brand Selection: Prioritize products from reputable and high-quality suppliers to ensure the performance and quality of the test chamber. At the same time, choose suppliers with comprehensive after-sales service and technical support to obtain timely technical assistance and maintenance services during use. It is an important tool for evaluating the performance of lithium-ion batteries under temperature shock. When selecting and using it, factors such as testing needs, chamber performance, and brand reputation should be comprehensively considered to ensure the accuracy and reliability of test results.
