GM ran over 300,000 simulated EV battery designs, using 300 million CPU hours, before building any physical cells, aiming to slash development time to about two years.
01Summary
- 01GM simulated more than 300,000 battery designs using 300 million CPU hours, equivalent to 34,000 years of computer time.
- 02The battery uses lithium manganese-rich (LMR) chemistry, offering 33% more energy density than LFP at comparable cost.
- 03GM’s self-driving software logs over 3 billion simulated miles per day, versus about 1 million real-world miles a month.
- 04The new central computer, with 40 times today’s processing power, debuts in 2028 on the Cadillac Escalade IQ.
- 05GM plans volume production of the LMR battery by 2028 at its Ultium Cells joint venture in Spring Hill, Tennessee.
02Why it matters
This matters because GM’s simulation-driven approach could halve vehicle development time, accelerating the shift to more efficient, cheaper EVs and challenging China’s dominance in battery technology.
