New energy batteries, as a key technology to achieve green transportation and energy transformation, their safety, efficiency and life have been the focus of industry research. In order to further promote the development of new energy batteries and solve the problem of heat dissipation that has always existed, the new energy battery pack direct-cooling direct-heat testing machine came into being. This is an epoch-making technology, which can not only efficiently and accurately evaluate the thermal management performance of the battery pack, but also provide real-time data feedback for the thermal design of the battery, which greatly promotes the optimization and upgrading of the battery management system (BMS).

　　The principle of the new energy battery pack direct-cooling direct-heat test machine is mainly to heat and cool the battery pack by simulating the working environment of the battery in the actual use process, so as to accurately measure the performance changes of the battery under different temperature conditions, including the battery's charging and discharging efficiency, battery life and safety performance under extreme temperature conditions. This test method can comprehensively and carefully evaluate the thermal management system of the battery pack, provide a scientific basis for the heat dissipation design of the battery, and ensure that the battery can still maintain good performance and safety under high load working conditions.

　　In the field of new energy vehicles, the performance of the battery is directly related to the power output, endurance and service life of the car, and the heat dissipation effect of the battery is one of the key factors determining the performance of the battery. Through the application of the new energy battery pack direct cooling and direct heat test machine, combined with advanced thermal management technology, while ensuring battery performance, it can effectively extend the service life of the battery, reduce maintenance costs, and provide strong technical support for the popularization and development of new energy vehicles.

　　In addition, with the continuous progress and development of the new energy industry, the application of the new energy battery pack direct cooling direct thermal testing machine will continue to expand to more areas, such as energy storage systems, portable electronic equipment, etc., to provide innovative solutions for thermal management in these areas, and further promote the vigorous development of the new energy industry.

　　In short, the development and application of the new energy battery pack direct cooling and direct heat test machine marks a major breakthrough in new energy battery thermal management technology, which can not only provide strong technical support for the thermal design of the battery pack, but also lay a solid foundation for the further development of new energy vehicles and other fields. In the future, with the continuous improvement and optimization of technology, it is believed that the new energy battery pack direct-cold direct-heat testing machine will play a more important role in promoting the green and sustainable development of the new energy industry.
