Heat-Absorbing Composite Strength Analysis for Electric Vehicles Battery Pack Cover

Abstract

One of the key components of Electric Vehicles is the battery pack compartment casing, which needs to be both as light and as strong as possible to cover maximum mileage while withstand vibrations and other mechanical abuse. A layer of thermal protection is also placed to the case because a typical Lithium battery used for an EV is very sensitive to temperature. In this study, a heat-absorbing lightweight composite for the battery pack compartment casing of an electric vehicle is physically constructed and put to the test to determine its mechanical characteristics. The latent ability of organic phase change materials to absorb heat without experiencing thermal rise led to their use as fillers for the resin composite. Depending on what type and how much phase change materials are utilized, the tensile evaluation reveals that the average strength is noticeably compromised. The composite preparation techniques, including the use of carbon fiber as reinforcement material, are also briefly covered in this paper.
