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.

Does aluminum make a good battery pack?

The larger the battery, the more aluminum makes sense for battery packs,” Asfeth asserted. 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.

Are aluminum battery enclosures a good choice?

Aluminum battery enclosures typically deliver a weight savings of 40% compared to an equivalent steel design. According to Asfeth, the alloys best suited for battery enclosures are the 6000-series Al-Si-Mg-Cu family — alloys that are also highly compatible with end-of-life recycling, he said.

Does Tesla have a steel 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. And public statements made by the company regarding the structural battery pack expected to come from Tesla’s Berlin plant indicate the upper and lower covers are steel.

Are EV batteries a 'battle for the box'?

The “battle for the box” has kicked off a new wave of creativity among engineers and materials scientists. Roughly 80% of current EVs have an aluminum battery enclosure, but engineers are quick to note that the field is wide open for alternatives, based on vehicle type, duty cycles, volumes, and cost.

What is an EV battery enclosure?

(Novelis) EV battery enclosures are a hotbed of subsystem design, materials innovation, and vehicle integration. The importance of supporting and protecting the EV battery has kicked off a new wave of creativity among engineers and materials scientists.”
