GM’s New EV Batteries Boast Some Trick Tech

General Motors says the Ultium battery packs powering its future electric vehicles, including the upcoming GMC Hummer, boast stackable internal cells allowing for enhanced flexibility in how engineers can incorporate them into a vehicle’s structure.

The stackable, pouch-like cells can be configured to fit several body styles, and they make up a major part of why GM can stretch the same tech between a small model such as the next version of the compact Bolt EV hatchback and a much larger rugged vehicle like the GMC Hummer EV pickup.

The batteries are also particularly power-dense, meaning they are optimized for quick charging and long range (an impressive 300 miles in the Hummer EV, which will weigh a staggering 9,000 pounds). GM says bigger vehicles like pickups and SUVs feature stacked cells. In contrast, upcoming sportier models will feature cells placed horizontally to keep ride height and the center of gravity ultra-low. They’re also part of a distinct drivetrain that includes a single-speed transmission and can be incorporated into various platforms.

For now, the Ultium tech is too costly for an inexpensive model like the recently-redesigned Bolt EV, which rides on a version of its predecessor’s platform.

GM unveiled the batteries in detail last year, and the automaker is ramping up production as it anticipates the arrival of the GMC Hummer EV Pickup by the end of 2021. A slightly shorter Hummer EV with an SUV body is due in showrooms by early 2023, too. See electric car models for sale
