Car Body Construction: The main skeleton of the car body has two types of panels: 1. Outer panel. 2. Inner panel. The outside panels provide the shape of the car body whereas the inner panels reinforce the shell of the body. The various curved shapes are given to outer panels to provide the strength to panels.

Safe and cost-efficient: A steel battery housing protects the heart of an electric car in a crash At the interface between the powertrain and the structural elements, the battery presents both manufacturers and material suppliers with a challenging design task.
Glass fibre top covers, bottom covers and impact protection plates can provide a more cost-effective material for battery cases. The most challenging factor is TRP, as the combustion needs to be contained in the box. Then there are EMI, thermal and electrical isolation and mechanical issues of drive loads, crashes and impacts to consider.
In a modular case, most of the materials are set in the battery platform. These include the plastic carriers, the adhesives and the busbars, all with a UL94 rating of V-0. The battery case casing is part of the vehicle integration, so each vehicle designer comes with different needs.
Life cycle assessments show that steel is the most sustainable material for battery housings. Up to two thirds less greenhouse gas emissions arise in the production of a steel battery housing compared with an aluminum design. During use, the carbon footprints of steel and aluminum battery housings are virtually identical.
Battery cases used as part of the chassis is an opportunity for composites, as designers need to close off the case with the top and bottom covers. This is good for torsional stiffness of car body. Then there is the side impact load case, which needs to transfer the load across the side rails.
