FEV and ITL proposed an improved concept of battery casing
FEV, a development service provider, and Impression Technologies (ITL), an aluminum metal expert, have jointly developed a concept for electric vehicle battery casings using "HFQ technology", aimed at optimizing the utilization of space available for energy storage.
According to FEV, by completely repositioning the structural components to the outside and integrating the battery casing into the entire vehicle, installation space can be created for additional battery units, thereby increasing range. Result: In the same installation space, more battery cells can be accommodated to achieve greater range, or the battery itself can become smaller at the same range.
FEV itself describes this method as the "Exoskeleton" of the battery shell. This structure is designed to ensure power flow is generated above and below the battery pack. On the one hand, this keeps the load generated during the collision away from the installation space used for the battery, while optimizing the stiffness of the entire system (battery and body shell), "the statement said. This requires a complex structure with a smaller radius and draft angle, which is where partner ITL leverages its HFQ technology.
Christian K ü rten, Director of Vehicle Architecture at FEV Vehicle, said, "HFQ technology has expanded our potential manufacturing technology portfolio for new development, enabling us to achieve more complex structures than cold forming technology In addition, high-strength aluminum alloy was used, combined with HFQ technology, ultimately providing the required performance in an optimized installation space. The concept developed by FEV and ITL will be manufactured and displayed as a demonstrator in the coming months.
