How to better control the heat generated in lithium ion battery in use process security?

Source: 2020 - 04 - 14 19:46 hits: how to properly study the lithium battery temperature field distribution in the lithium ion battery charging and discharging process and how to better study and control of lithium ion battery research work mainly includes the following aspects: 1. Understand the development trend of the lithium ion battery and the existing problems in the application, especially the fever in the lithium ion battery in use process and safety hidden trouble. 2. Through various channels, I studied the theory knowledge, understand the classification, the characteristic of the lithium ion battery, working principle and composition of the material, understand the heating mechanism of lithium ion battery of lithium ion battery temperature field analysis provides a theoretical basis. 3. Combined with the knowledge of heat transfer, combined with the knowledge of the finite element, according to the situation in the process of practical application, the entity the working process of the lithium ion battery and hot issues, abstract, law, formulate, preliminary chose one general,, of course, the appropriate assumptions and simplify the Li - heat treated Ion battery mathematical model. 4. This paper studied the finite element knowledge and analysis, and studied the ANSYS through books, provide a means for thermal analysis. 5. Using ANSYS software to the shape of two common single lithium ion battery temperature field is analyzed, and the defective lithium ion battery has carried on the preliminary analysis. On this basis, the author of how to control the battery in the process of using thermal safety issues put forward its own views. All in all, this paper for the temperature field of a further research on lithium ion battery, lithium ion battery and how to better control in the process of using thermal safety problems has higher reference value.
