What is stellantis' new 'STLA frame' chassis?

Stellantis (NYSE:STLA) has debuted its new "STLA Frame" chassis for full-size trucks and SUVs, designed to fit electrified powertrains and other energy solutions.

Is structural energy storage a viable EV?

The Volvo was a proof of concept that structural energy storage was viable in an EV, and the success of the Storage project generated a lot of hype about structural batteries. But despite that enthusiasm, it took a few years to procure more funding from the European Commission to push the technology to the next level.

Which EVs use a multi-material battery enclosure?

Bucking that trend is GM’s 9000-lb. (4082-kg) Hummer EV, which uses a multi-material battery enclosure. Tesla also has reduced the amount of aluminum in the battery enclosure for the Model 3 and Model Y compared to what was used in its S and X models.

What is an EV battery enclosure?

(Novelis) EV battery enclosures are a hotbed of subsystem design, materials innovation, and vehicle integration. Whether you call them packs, boxes, or trays, the structures that envelop and protect EV battery cells and their supporting electrical and thermal-management hardware are among the industry’s top subsystem priorities.

Can a car's battery pack be used for energy storage?

But for Greenhalgh and his collaborators, the more promising approach is to scrap the battery pack and use the vehicle’s body for energy storage instead. Unlike a conventional battery pack embedded in the chassis, these structural batteries are invisible.

Why are EV battery enclosures made out of aluminum?

Suppliers of composites and plastics are undeterred by aluminum’s current dominance in EV battery enclosures. They’re developing new formulations and processes aimed at matching or exceeding the performance and cost-competitiveness of the light metal. “Current battery packs use a lot of metal that is not optimized.
