With the continuous development of the new energy vehicle industry, battery technology, as one of its core technologies, continues to make new breakthroughs. Among them, the emergence of the new energy vehicle power battery pack high and low temperature coolant test machine produced by Yunhai has brought no small changes to the development and production of new energy vehicle batteries.

　　This test machine is built by Yunhai, providing a comprehensive solution for the high and low temperature performance test needs of new energy power battery packs. The temperature control range reaches -40℃~85℃, and the temperature control accuracy is as high as ±0.1℃, which provides a strong guarantee for the performance of the battery pack in various extreme environments.

　　In terms of flow control, the high and low temperature coolant testing machine achieves a wide range of 1-30L/min, and the flow control accuracy reaches 0.1L/min, ensuring the accuracy and stability of the test process. At the same time, the constant pressure control is 0~300Kpa, and the pressure control accuracy reaches 5Kpa, which provides a solid backing for the safety performance of the battery pack.

　　It is worth mentioning that this high and low temperature coolant testing machine has a high degree of flexibility in the communication mode, supporting CAN2.0, Ethernet and RS485 and other optional ways to meet the actual needs of different users. In addition, its cooling and heating power output power is adjustable, providing users with a more convenient operating experience.

　　In terms of functions, this high and low temperature coolant testing machine can be described as a complete package. It has a data storage function, which can record the running time of the device, the running time of the program segment and various key parameters in real time, and the data can be saved for up to 60 days, which is convenient for users to consult and analyze at any time. At the same time, the test machine also has a strong security protection function, even in the case of unguarded to ensure the safe operation of the equipment.

　　In addition, the high and low temperature coolant tester also realizes the function of liquid circulation output and automatic replenishment, which effectively improves the test efficiency. Each time the battery pack is replaced, the device can automatically recycle all the internal liquid, avoiding waste and pollution of the environment. The equipment also comes with a drain port for easy repair and maintenance.

　　In terms of controllability, the high and low temperature coolant testing machine adopts a humanized design. Its standard RS-485 interface and reserved CAN2.0 communication interface enable users to easily set the temperature value, flow value and standby/operation selection through the upper computer. At the same time, the device supports the segmented temperature control function, and users can set up to 10 program formulas and 40 fine controls for each program according to their needs.

　　On the man-machine interface of the device operation panel, the user can view all the current data values in real time and the real-time display of the curve value formed in proportion to time. This design makes the testing process more intuitive and convenient.

　　In the discharge test, the high and low temperature coolant tester shows excellent performance. Even if the return liquid temperature is less than 60 ° C due to the heat generated by the battery pack discharge, the flow rate at the outlet can still be controlled within the range of ≤30L/min and the temperature accuracy at the outlet of the refrigerant can be controlled less than or equal to 25 ° C.
