GM battery laboratory, MIUS – The vehicle-maker will upgrade its facilities at the Detroit-Hamtramck Assembly and Brownstown Battery Assembly plants in Michigan in preparation for the next generation of electric vehicles and advanced battery technologies.

The investment is the largest GM has made to date at the two facilities, with the majority ($384m) heading to Detroit-Hamtramck for new bodyshop tooling, equipment and other upgrades to support manufacture of the next generation of Chevrolet Volt, plus two future products. The remaining $65m will be spent at Brownstown on next-generation lithium-ion (Li-ion) battery production and future battery systems.

Detroit-Hamtramck currently mass-produces extended-range electric vehicles including the Volt, Cadillac ELR and Opel Ampera for 33 markets worldwide; Brownstown makes the Li-ion battery packs for these vehicles.
