Developing new EV battery technology takes years of research. General Motors, for example, says it’s put a decade of effort into lithium manganese-rich, or LMR, batteries, which aren’t yet in any of their vehicles on the road.

But recently, the automaker says it made a big leap in that work. Using computer modeling, GM was able to virtually test more than 300,000 LMR battery pack configurations, advancing from first concept to formal approval in under a month.

That represents more than 300 million CPU hours, which would take a typical computer 34,000 years, while running 24 hours a day, to complete, according to GM.

GM is leaning into artificial intelligence and virtual simulations to develop its vehicles.…
