Overview

The high and low temperature alternating test chamber adopts a dry wet bulb or capacitive multifunctional multi-stage programmable temperature and humidity controller, a fuzzy PID controller, and small temperature and humidity fluctuations.

Product Details

High and low temperature alternating test chamberAlso known as a temperature chamber, temperature circulation chamberhigh-low temperature chamberHigh and low temperature aging chamber, programmable high and low temperature aging test chamber, high and low temperature cycling test chamber, etc. Used to simulate the temperature changes in the atmospheric environment. Inspect the performance indicators of components and materials of electronic and electrical products, automobiles, aerospace, marine weapons, medical equipment (drugs), universities, research institutions, and other related products under high and low temperature (alternating) cyclic changes.

High and low temperature alternating test chamberinBattery cell testingThe applications mainly involve the following aspects:

1. Temperature cycling test: In the high and low temperature aging test chamber, cycling tests under different temperature environments can simulate the high and low temperature environments of battery cells in actual use scenarios, in order to evaluate the performance of battery cells in different environments.

2. High temperature aging test: By conducting a high-temperature aging test on battery cells in a high-temperature test chamber for a period of time, the stability and safety of the cells under long-term high-temperature environments can be evaluated to predict their lifespan and performance degradation.

3. Low temperature discharge test: By conducting discharge tests on battery cells in a low-temperature test chamber, the capacity and performance changes of the cells in low-temperature environments can be evaluated.

4. Constant temperature test: For some battery cells that need to work under specific temperature conditions, such as power battery cells, constant temperature tests can be conducted in high and low temperature aging test chambers to evaluate their performance in specific temperature environments.

Through relevant tests, the performance and stability of battery cells can be comprehensively evaluated, providing reference for the design and production of battery cells.
