GM simulated 300,000 EV battery designs — using 34,000 years of computer time — before building a single cell. Now comes the physical part
At GM Forward, the automaker showed how much of its next generation of vehicles is now designed and tested in simulation. The real cells come later.
GM just did 34,000 years of battery testing in less than a month. Here’s how
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…
General Motors states that it evaluated more than 300,000 battery designs by simulations before making a single cell. The decisive test, however, is yet to come: its manganese-rich chemistry will have to demonstrate in production that it can combine more energy density with a competitive service life.
