Battery case technology

The future of the global automotive industry revolves around electrical technology. While high production costs and end-of-life battery disposal are still unresolved issues, the good news is that technological research is moving forward, that the incentives for a shift to electric cars are in place and, where there is a desire to make the change to clean mobility, research is being supported by governments as well as by increasingly ecological consumers. In 2030, electric cars are expected to exceed 30% of the sector.

The Maserati Grecale prototype
In this context, Eurodies offers its contribution with a key bodywork component: the battery housing module, or battery case. Our first project, destined for the Maserati Grecale, started with the development of the first six demonstrators. In October 2020, the system entered the next phase for car prototype production and in 2021 we developed a further, more advanced prototype step.

Innovative technologies developed in-house
The creation of this component has required us to adopt innovative technologies which we’ve studied and developed internally, in order to meet the strict technical specifications that the assembled item must satisfy. In fact, the aluminum structure of the battery case is made of semi-finished products obtained from several
alloys and different processes: cast, extruded, deep drawing. The real challenge is to respect the tight assembly tolerances and ensure that the housing is perfectly watertight.

A new leak test in record time
These requirements necessitated a phase of experimentation on innovative processes and the development of ad hoc equipment to test the component – such as, for example, a new leak test instrument, developed in just two weeks, compared to the eight months required for delivery if commissioned externally. We’re proud to have satisfied the customer, proving once again that our team is able to adapt their skills to meet new, ambitious goals.
