Cast aluminum housing energy storage battery

Should EV battery enclosures be made out of aluminum?

Soon, it may no longer be economically beneficial to use aluminum, especially for the small cars that have moderate range and target the lowest possible price point.” Aluminum is the dominant material for electric vehicle (EV) battery enclosures for one simple but significant factor: lightweighting capability.

Are aluminum battery enclosures a good choice?

Aluminum battery enclosures or other platform parts typically provide a weight savings of 40% compared to an equivalent steel design. The most-used and best-suited alloys for battery enclosures are of the 6000-series Al-Si-Mg-Cu family, Afseth shared, noting that these alloys are “very well compatible” with end-of-life recycling.

What material is used for a battery enclosure?

The majority of long-range BEVs in production use aluminum as the main material for the battery enclosure. (Constellium) Mass reduction is the main driver behind aluminum battery enclosures, but thermal requirements prove challenging for the lightweight material.

Are aluminum battery enclosures recyclable?

Aluminum battery enclosures or other platform parts typically gives a weight saving of 40% compared to an equivalent steel design. Aluminum is infinitely recyclable with zero loss of properties. At end of life 96% of automotive aluminum content is recycled. Recycling aluminum only requires 5% of the energy needed for primary production.

What is the best material for a BEV battery enclosure?

Aluminum as sheet and extruded profiles is the preferred material for BEV body structure, closures and battery enclosures. Aluminum battery enclosures or other platform parts typically gives a weight saving of 40% compared to an equivalent steel design. Aluminum is infinitely recyclable with zero loss of properties.

Can aluminum battery enclosures be used for small cars?

(Constellium) Mass reduction is the main driver behind aluminum battery enclosures, but thermal requirements prove challenging for the lightweight material. Soon, it may no longer be economically beneficial to use aluminum, especially for the small cars that have moderate range and target the lowest possible price point.”
