The role of the battery housing in the body-in-white. Another key development in battery technology affecting enclosures is the evolution of the role of electric vehicle batteries in the body-in-white. Originally a body-in-white support component, battery casings are now becoming structural parts of the body-in-white, and automakers are even
The integration of the battery pack''s housing structure and the vehicle floor leads to a sort of sandwich structure that could have beneficial effects on the body''s stiffness (both torsional and bending). This paper also proposes some considerations that are related to the impact protection of the battery pack, with particular reference to
Battery Module/Pack Housing; Connectors and Wiring; The components of a battery pack are critical for its performance and safety. Each element plays a unique role in ensuring the effective operation of the entire system. Understanding these components helps in grasping how a battery pack functions. Cell: A battery pack begins with the cell, which is the
One area where all current manufacturers seem to take their own direction is the structural design of battery packs. These range from traditional fabricated, stamped steel
Among all cell components, the battery shell plays a key role to provide the mechanical integrity of the lithium-ion battery upon external mechanical loading. In the present study, target battery shells are extracted from commercially available 18,650 NCA (Nickel Cobalt Aluminum Oxide)/graphite cells. The detailed material analysis is conducted to reveal a full
The main cost driver of a battery system are the battery cells as the smallest unit. Many battery cells are connected and mounted in a battery module. Several battery modules

One area where all current manufacturers seem to take their own direction is the structural design of battery packs. These range from traditional fabricated, stamped steel structures, through to advanced aluminum and composite productions.
A battery housing consists of the actual stainless steel housing, which creates the structural load capacity between the components, batteries and control components in the interior. Lithium-ion batteries work optimally when they are operated in a temperature range between 18 and 25 °C. Maintaining this temperature range usually requires the use of a
For safety, the design of the battery housing can''t be considered isolated. The vehicle and battery concept must be planned together. In a vehicle with a highly rigid body, the battery housing must withstand less in the event of a collision. On the other hand, if the vehicle structure is softer, it needs a more stable battery housing. If the
The primary function of the battery pack housing is to protect the battery cells inside. The battery may suffer from a variety of external shocks during operation, such as physical collision, vibration, moisture and chemical corrosion. The strength and toughness of the housing material can effectively prevent these external factors from causing

This solution is also one of the most interesting from the point of view of the battery pack protection in case of a lateral impact and for easy serviceability and maintenance.
Extensive calculations are then carried out to determine the battery pack's energy, capacity, weight, and size. The design involves grouping cells into modules for easier management and protection, while also incorporating cell holders to enhance stability and minimize vibrations.
Arora and co-workers have developed a study related to the battery packaging design aimed to maximize its reliability and mitigate the safety risks in case of impact. They pay particular attention to the side impact but without developing a simulation analysis of the sketched solutions.
The structure is completed by the top enclosure, which seals the battery pack. Sometimes the vehicle structures tend to exploit the volume under the rear seats with a battery pack protrusion that is typically dedicated to host the electronic circuits for the Battery Management System (BMS).
The required battery pack is a big, heavy, and expensive component to be located, managed, climatized, maintained, and protected. This paper develops some engineering analyses and shows sketches of some possible solutions that could be adopted. The possible consequences on the position
The structural problems have already been considered in the published literature. Luttenbeger and co-workers developed a study concerning the safety behavior of a battery pack in case of impact. They have considered both the frontal impact and the pole side impact according to EuroNCAP standards.
