Automotive battery pack test ambient temperature simulation water chiller

The following are the key points for using water chiller to regulate the temperature of an automotive battery pack:

1. Temperature range:

The chiller needs to be able to provide a wide temperature range from low temperature (such as -40°C) to high temperature (such as 60°C or even higher) to simulate the different environmental conditions that the battery pack may encounter.

2.Temperature control accuracy:

In order to ensure the accuracy of the test results, the water chiller needs to have high-precision temperature control capabilities, usually requiring a temperature control accuracy within ±1°C.

3.Rapid temperature changes:

The ability to quickly switch between high and low temperatures to simulate the rapid temperature changes of the battery pack under different temperature conditions is very important for evaluating the thermal management performance of the battery system.

Application scenario examples:

1. Thermal cycle test: simulate the performance of the battery pack under different temperature conditions and evaluate the thermal cycle performance and durability of the battery pack.
2. Charge and discharge test: perform charge and discharge tests under different temperature conditions to evaluate the charge and discharge performance and capacity retention rate of the battery pack.
3. Thermal management system test: evaluate the performance of the thermal management system of the battery pack under different temperature conditions to ensure that the battery pack can effectively control the internal temperature.
4. Safety test: perform safety tests such as overcharge, overdischarge, and short circuit under extreme temperature conditions to evaluate the safety performance of the battery pack.
5. Environmental simulation test: simulate temperature conditions in different geographical environments to evaluate the performance of the battery pack in different environments.

By using water chiller to adjust the temperature of the automotive battery pack, it can ensure that the battery pack exhibits consistent performance under various temperature conditions, which is of great significance for verifying the thermal management performance of the battery system and improving the reliability and safety of the battery system.
