With the rapid development of new energy vehicles and renewable energy storage technologies, the R&D of new energy batteries has attracted much attention. In the R&D process of new energy batteries, temperature has a significant impact on the performance, life and safety of batteries. Dry-block calibrators have important applications in temperature regulation in new energy battery R&D. It can be used to accurately control the temperature environment in the battery material testing process, study the changes in the electrochemical properties of battery materials at different temperatures, and provide data support for the optimization of battery materials. In the performance test of battery cells and battery packs, dry-block calibrators can simulate the working state of batteries under different charge-discharge rates and ambient temperatures. By adjusting the temperature of the dry-block calibrator, the changes in battery parameters such as voltage, capacity and internal resistance can be observed, so as to evaluate the performance and thermal stability of the battery. In addition, dry-block calibrators can also be used in the R&D test of battery thermal management systems, helping to optimize the design of thermal management systems, ensuring that the battery can be in a suitable temperature range during actual use, and improving the overall performance and safety of new energy batteries.
