Discussion on the Application of New Thermal Insulation Materials for Power Batteries of New Energy Vehicles Based on Computer Analysis

Abstract

Abstract With the widespread use of battery insulation systems, there are many optimizations for the size of the battery space in the box, the arrangement and combination methods, but there are few optimizations for the design of the battery inlet and outlet. This paper analyzes the battery insulation materials, builds a power battery heat generation analysis model, and analyzes the battery air outlet angle flow analysis, the air inlet angle material comparison analysis, and the FLUENT software is used for numerical simulation analysis to obtain the overall smooth characteristics and partial Flow rate and temperature distribution range. Finally, through the analysis of the experimental results, it can be known that for batteries with the same structure, the use of battery insulation materials can effectively improve the battery performance and extend the service life.
