Super-Fast Electric Car Charging, with a Tailor-Made Touch
Scientists report that they’ve designed superfast charging methods tailored to power different types of electric vehicle batteries in 10 minutes or less without harm.
The researchers will present their results today at the fall meeting of the American Chemical Society . ACS Fall 2022 is a hybrid meeting being held virtually and in-person Aug. 21–25, with on-demand access available Aug. 26–Sept. 9. The meeting features nearly 11,000 presentations on a wide range of science topics.
One solution to this conundrum is to tailor the charging protocol in a way that optimizes speed while avoiding damage for the many different types of battery designs currently used in vehicles. But developing optimal protocols requires a huge amount of data on how various methods affect these devices’ lifetimes, efficiencies and safety.
“We’ve significantly increased the amount of energy that can go into a battery cell in a short amount of time,” says Dufek. “Currently, we’re seeing batteries charge to over 90% in 10 minutes without lithium plating or cathode cracking.”
