With the rapid development of the new energy vehicle industry, battery performance and safety have become the focus of attention of consumers and manufacturers. In this context, the new energy vehicle battery pack liquid cooled test machine came into being, which has brought revolutionary changes to the field of battery testing.

　　The new energy vehicle battery pack liquid cooling test machine is a comprehensive set of equipment developed for the power battery test of the new energy industry, which integrates the functions of temperature, flow, remote monitoring, data acquisition and program control. This device not only provides a standard communication protocol, which is easy to integrate with the charge-discharge device, BMS and other software, but also realizes the integrated test management, which greatly improves the test efficiency and accuracy.

　　The test machine plays an important role in the development and production process of new energy vehicle battery packs. Its main applications include thermal management test, electrical performance test, working condition cycle life test, liquid cooling plate exchange high and low temperature impact test and liquid cooling system matching test. Through these tests, the performance of the battery pack in various environments can be effectively evaluated, providing a strong guarantee for the reliability and safety of the vehicle.

　　In terms of equipment composition, the new energy vehicle battery pack liquid cooling test machine uses a number of advanced technologies. The circulating pump adopts variable frequency motor, which can adapt to a wider temperature and pressure range according to the experimental requirements. At the same time, the equipment is also equipped with filters to reduce noise and air liquid filtration to ensure a smooth test process. In addition, the pipe interface of the equipment adopts the principle of down into and up out to ensure the smooth circulation of the heat conduction medium.

　　It is worth mentioning that the whole pipeline of the test machine adopts a fully closed cycle, which will not volatilize a lot at high temperature and will not absorb water at low temperature. The system is also equipped with an expansion tank, which can automatically absorb and fill the thermal conductivity medium in the circulation pipeline to ensure the stable operation of the system. At the same time, the equipment is also equipped with three-color lights and buzzers, real-time feedback of the operating status of the equipment, convenient for operators to understand the equipment in time.

　　The temperature range of the new energy vehicle battery pack liquid cooled test machine is usually from -40 ° C to 100 ° C (can be extended to 150 ° C), while controlling the temperature, you can also choose to control the flow or pressure. This function enables the device to effectively test the environmental adaptability of the battery pack, improve the reliability of the vehicle, and ensure the good operation of the vehicle in a variety of complex environments.
