Geely’s AI fast charging ‘heals’ EV batteries for 20% more cycle life

Chinese automaker Geely has unveiled a new fast-charging system it says can actually undo some of the wear that fast charging puts on an EV battery. Its fifth-generation charging station puts out up to 2,250 kW, fast enough to take a battery from 10% to 70% in about 4.5 minutes. But the more interesting part is what Geely calls "pulse restoration" technology, which sends small pulses of current through battery cells to reactivate lithium that has built up on the negative electrode during repeated fast charging. That buildup, called lithium plating, is a major reason batteries lose capacity over time. Geely claims the pulse technology, paired with AI-managed charging, can add up to 20% more cycle life, meaning the battery could last through more charge cycles before it wears out.

Geely also says it has a home-charging strategy that works overnight at a slower rate to gradually repair damage from fast charging, essentially letting home charging clean up after road-trip supercharging. An AI system called Xingrui PowerMind manages this by predicting battery temperature up to 30 seconds ahead and adjusting power and cooling before the pack overheats.

None of this is available in the US yet, and most EVs sold here charge far slower than what Geely is testing in China. Still, the idea that fast charging damage could be partly reversible, rather than something drivers just have to live with, is notable, and it may show up in future EV designs as battery and charging technology keeps advancing.
