GM unveils long-range battery to power its new electric vehicles
U.S. automaker General Motors Corp. (GM) yesterday unveiled a new long-range battery to power an expanded lineup of electric vehicles.
The heart of GM’s strategy is a modular propulsion system and a highly flexible, third-generation global EV platform powered by proprietary Ultium batteries.
“Our team accepted the challenge to transform product development at GM and position our company for an all-electric future,” said Mary Barra, GM chairman and CEO. “What we have done is build a multi-brand, multi-segment EV strategy with economies of scale that rival our full-size truck business with much less complexity and even more flexibility.”
“Thousands of GM scientists, engineers and designers are working to execute an historic reinvention of the company,” said GM President Mark Reuss. “They are on the cusp of delivering a profitable EV business that can satisfy millions of customers.”
Ultium Batteries and Propulsion System Highlights
- GM’s new Ultium batteries are unique in the industry because the large-format, pouch-style cells can be stacked vertically or horizontally inside the battery pack. This allows engineers to optimize battery energy storage and layout for each vehicle design.
- Ultium energy options range from 50 to 200 kWh, which could enable a GM-estimated range up to 645 kilometres or 400 miles or more on a full charge with 0 to 60 miles per hour (mph) acceleration as low as 3 seconds. Motors designed in-house will support front-wheel drive, rear-wheel drive, all-wheel drive and performance all-wheel drive applications.
- Ultium-powered EVs are designed for Level 2 and DC fast charging. Most will have 400-volt battery packs and up to 200 kW fast-charging capability while its truck platform will have 800-volt battery packs and 350 kW fast-charging capability.
GM’s flexible, modular approach to EV development will drive significant economies of scale and create new revenue opportunities, including:
- Continuous Improvement in Battery Costs: GM’s joint venture with LG Chem will drive battery cell costs below USD100/kWh. The cells use a proprietary low cobalt chemistry and ongoing technological and manufacturing breakthroughs will drive costs even lower.
- Flexibility: GM’s all-new global platform is flexible enough to build a wide range of trucks, SUVs, crossovers, cars and commercial vehicles with outstanding design, performance, packaging, range and affordability.
- Capital Efficiency: GM can spend less capital to scale its EV business because it is able to leverage existing property, including land, buildings, tools and production equipment such as body shops and paint shops.
- Complexity Reduction: The vehicle and propulsion systems were designed together to minimize complexity and part counts beyond today’s EVs, which are less complex than conventional vehicles powered by internal combustion engines. For example, GM plans 19 different battery and drive unit configurations initially, compared with 550 internal combustion powertrain combinations available today.
- Rising Customer Acceptance: Third-party forecasters expect U.S. EV volumes to more than double from 2025 to 2030 to about 3 million units on average. GM believes volumes could be materially higher as more EVs are launched in popular segments, charging networks grow and the total cost of ownership to consumers continues to fall.
- New Sources of Revenue: By vertically integrating the manufacture of battery cells, the company can reach beyond its own fleet and license technology to others.
GM said its first generation of future EV program will be profitable. GM’s technology can be scaled to meet customer demand much higher than the more than 1 million global sales the company expects mid-decade.
Chevrolet, Cadillac, GMC and Buick will all be launching new EVs starting this year. The next new Chevrolet EV will be a new version of the Bolt EV, launching in late 2020, followed by the 2022 Bolt EUV, launching in the Summer of 2021. The Bolt EUV will be the first vehicle outside of the Cadillac brand to feature Super Cruise, the industry’s first true hands-free driving technology for the highway, which GM will expand to 22 vehicles by 2023, including 10 by next year.
The Cruise Origin, a self-driving, electric shared vehicle, shown to the public in January 2020 in San Francisco, California, U.S.A., was the first product revealed using GM’s third generation EV platform and Ultium batteries. Next will be the Cadillac Lyriq luxury SUV in April. Details about its launch will be shared then. The launch of the Ultium-powered GMC HUMMER EV will follow in May.
