Every kind of thing has its value, in our daily life, there are many inseparable things and products. So in the industrial field, there are a lot of mechanical equipment in different areas to play their role, power battery testing is no exception, today we will talk about the requirements of power battery testing.
due to the energy density in the requirements of power battery detection, the current vehicles basically have no heating management system. However, in order to raise the subsidy threshold, the state has added some requirements. Electric buses require IP67 compliance and a thermal management system. He suggested that if there are no subsidies in the future, companies can consider adding a thermal management system to the battery system to ensure that the battery can work at a more suitable temperature, such as 25-35 degrees, and the battery pack can be reduced. The temperature difference. He said that after the temperature is controlled, it is safe, reliable and guaranteed, and the practicability is also very good. It is warm in winter and cool in summer, and electric vehicles can basically be used in every corner. CAE-Computer-Aided Engineering refers to the use of computer-aided solutions to analyze the structural mechanical properties of complex projects and products and to optimize structural performance. In the requirements of power battery detection, CAE software can be used for static structure analysis and dynamic analysis, linear and nonlinear problems in the requirements of power battery detection, and analysis of various structures (solids), fluids, electromagnetics, etc. CAE technology is used to simulate and simulate the changes of various reliability parameters of power battery in the product cycle, which provides the basis for the structural optimization of power battery module. By comparing with the actual test data, it plays an important role in improving the reliability of the power battery pack.
Among them, CAE simulation technology mainly includes the following aspects in battery pack simulation analysis: battery pack thermal management: design cooling system according to temperature field distribution; Analysis of battery mechanical performance in power battery testing requirements: impact of collision and rolling on battery; Battery electrical performance analysis: influence of overcharge/overdischarge, large current, charge/discharge, external short circuit on battery; Noise, vibration and acoustic vibration roughness analysis: flow noise, structural vibration; structural durability analysis.
The development prospect of the power battery testing industry is very good, because it brings more benefits to the enterprise when it is used, so it is favored by customers. The above is his small knowledge point, hoping that more people can bring help. We will have more additions in the future, welcome to have a look. Then when you purchase, we also suggest that you find regular and powerful manufacturers. In this case, the price is also guaranteed.
