GM revealed their new EV platform and their new Ultium batteries for EV Day.

GM's Ultium batteries will cost less than $100 per kilowatt-hour and allow for a driving range of up to 400 miles on a full charge, GM said. That's about 50 percent more than the 259-mile range for the 2020 Chevrolet Bolt.

GMC Hummer EV, expected to go into production in fall 2021, will be the first vehicle to use the new battery technology, GM said

There will be 10 new EVs from GM including a Hummer SUV, a midsize Chevy SUV, a Buick SUV and crossover and three Cadillacs.

GM will design the electric motors in-house. The vehicle systems and propulsion systems are much less complex than traditional internal-combustion powertrain combinations, GM said. The automaker plans 19 different battery and drive-unit configurations to start, compared with 550 internal-combustion powertrain options available today.

The Ultium batteries have 60 percent more power than the batteries in the current Bolt, GM said. They have large-format, stackable pouch-style cells for more flexibility and optimal battery energy storage.

GM is nowhere near the bottom of the battery-cost curve, engineer Andy Oury said.

The automaker aims to manufacture the batteries through its $2.3 billion joint venture with LG Chem in Ohio and could license the technology to other companies.

The Ohio battery plant will have an annual capacity of more than 30 gigawatt-hours, making it among the largest in the world, with potential for expansion, GM has said.

The automaker has said it plans to build 20 EVs globally by 2023 and is converting its Detroit-Hamtramck Assembly plant that was slated for closure into an EV manufacturing hub with a $3 billion investment.
