At some point, electric-car charging numbers become difficult to process. Ten minutes sounds fast. Seven minutes sounds very fast. And by now, Geely has demonstrated a system that took a battery from 10 to 70 percent in four minutes and 30 seconds.
That’s roughly enough time to walk into a service station, discover there’s a queue for coffee and return to the car slightly annoyed.
The technology is called Geely Smart Charging, and unlike some laboratory battery announcements, Geely describes this as its fastest production-ready charging performance to date. In real-world testing with the battery technology used in the Lynk & Co 10 and Zeekr 001, 10–97 percent took eight minutes and 40 seconds.
Raw charging power is only half the story.
Geely’s new fifth-generation charging station is capable of a peak 2,250 kW, while its Shendun Golden Battery supports charging rates as high as 12C. Those numbers are enormous, but forcing energy into a battery that quickly creates an equally enormous problem: heat. And Geely’s answer is AI.
The Xingrui PowerMind system predicts battery temperature up to 30 seconds in advance and adjusts charging power before temperatures become problematic rather than simply reacting afterward. The target is to keep average battery temperature below 55°C and peaks below 65°C.
There’s also liquid cooling in five places across the charging chain, including the station’s energy storage, charger, cable, vehicle charging port and battery pack.
That sounds like a lot of engineering just to spend less time beside a charger.
But charging speed has reached the point where thermal management may be more important than the headline kilowatt figure.
Battery degradation is the other obvious concern. Repeated ultra-fast charging isn’t something owners generally associate with extending battery life, so Geely has developed what it calls lithium-ion pulse restoration. Tiny current pulses are intended to reactivate lithium ions accumulated around the negative electrode after repeated fast charging.
Combined with its AI charging management, Geely claims the technology can improve battery cycle life by up to 20 percent.
That’s a manufacturer claim rather than something we can independently verify after ten years of customer use, which is worth keeping in mind.
Geely is also developing a new Ultra Short Blade Battery for less expensive vehicles. It reaches 6C charging and uses revised laser welding that the company says reduces charging heat by 10 percent.
The obvious obstacle isn’t inside the car.
A vehicle capable of accepting extraordinary charging power doesn’t magically create a 2.25-megawatt charger at the motorway services down the road. Grid capacity, charger rollout and cost will determine how often drivers actually experience anything close to these numbers.
Still, the direction is fascinating. For years the EV industry’s answer to range anxiety was simply more battery.
Geely is making a different argument: perhaps the battery doesn’t need to become enormous if stopping to charge it eventually takes little longer than buying that coffee.
