A battery pack consisting of battery cells and electronic components enclosed within the battery compartment must meet the ISO 12405 standard, which requires no physical damage to be shown. Finally, the summary of flame retardancy, mechanical properties, and manufacturability is tabulated in Table 4 at the end of Section 4. 4.1. Flame Retardants. In
The fourth stage began in 2014, the first year of China''s new energy vehicle promotion and the official start of the market introduction period of new energy vehicles in China [4]. The Chinese government has always adhered to the "Three Verticals and Three Horizontals" strategic layout and has gradually focused on the strategic orientation
battery and required protection housing can be compensated partly by lightweight design to make vehicles efficient and provide driv-ers with the maximum possible range. In this process, it is not enough to just make the housing lightweight. In addition the corre-sponding concept must be as reliable and safe as possible in the long term. For

This paper discusses the potential of using lightweight nature-inspired cellular structured designs as energy absorbers in crashworthiness applications for electric vehicles (EV).
Therefore, manufacturers are looking for new material solutions to produce lighter batteries. Manufacturing a housing for a car battery and materials used. The materials used to manufacture a car battery housing must meet high requirements in terms of impact strength, thermal insulation or resistance to fire and electrical breakdowns.
In this paper, our attention is focused on the architectural modifications that should be introduced into the car body to give a proper location to the battery pack. The required battery pack...

In the best designs, the battery and enclosure greatly enhance vehicle structure and ability to absorb crash energy. To perform under these requirements, it is imperative to select the best materials and manufacturing processes for the housing and structure, which comprise as much as 20% of the cost and the weight of the battery system. The
Current battery housing designs 4, 5, typically made of solid metallic materials and located at the bottom of the vehicle, are usually heavy to ensure adequate protection. To progress the state-of-the-art battery housing design, efforts have been devoted towards lightweight, high mechanical performance, and efficient thermal management 6.
This paper develops some engineering analyses and shows sketches of some possible solutions that could be adopted. The possible consequences on the position of the vehicle center of gravity, which in turn could affect the vehicle drivability, lead to locate the battery housing below the passenger compartment floor.
In order to lower the possible negative consequences, the battery housing is generally located below the passengers compartment floor. This solution is also one of the most interesting in terms of battery pack protection in case of a lateral impact and for easy serviceability and maintenance.
A single battery housing unit is regarded as a representative component of the entire battery pack, and the dimensions are related to the overall size as entailed in Eq. (1). The design domain is intended to be occupied by lattices.
Stainless steel concept for an EV battery compartment. Li-ion modules for EVs generate a significant amount of heat inside the sealed battery housing. In the event of damage, the liquid coolant must not come into direct contact with the modules.
