Lighter Weight Battery Enclosure

By on September 30, 2019 in IN THE NEWS

Novelis Inc., a world leader in aluminum rolling and recycling, has developed the first aluminum sheet battery enclosure solution to address customers’ needs in the rapidly growing electric vehicle and battery markets. This innovative design for next generation automobiles provides a more sustainable mobility solution in battery electric vehicles, a market that is expected to more than triple globally by 2025.

Built with Novelis Advanz™ aluminum products and part of the Novelis Alumineering™ Solution portfolio, a collection of design solutions for the automotive industry, the enclosure is up to 50-percent lighter than an equivalent steel design. As a result, it matches the best energy density in the industry by enabling more than 160 watt-hours per kilogram, an extremely efficient design for OEMs and Tier 1 battery-pack manufacturers. It also can accommodate all battery cell types and is designed particularly for battery electric vehicles with larger power packs such as pickup trucks, sport utility vehicles and crossovers.

For mass-production electric vehicles, Novelis’ aluminum sheet design is a cost-effective solution when compared to aluminum extrusion and casting intense designs, and has low $/kg saved premiums compared to equivalent steel designs at substantially lower weight.

“Novelis’ approach to the battery enclosure opportunity focuses on smartly balancing lightweighting with production cost, structural and thermal efficiency, and crash management, which we believe are the key drivers for adopting an aluminum-intensive solution for the marketplace,” said Kai-Uwe Salzmann, vice president and CTO, EDAG Inc.
