Geely announced an AI-powered fast-charging system that it says not only reduces the effects of high-power charging, but may also reverse some of the degradation associated with it and increase operational battery life by up to 20%. The announcement comes as the ultra-fast-charging race expands in China, where companies are increasing power levels that could place thermal and chemical stress on lithium-ion cells.
Charging from 10% to 97% in Less Than Nine Minutes
The fifth-generation Geely Smart Charging Station delivers a maximum output of 2,250 kilowatts. In tests presented by the company, a battery used in the Lynk & Co 10 and Zeekr 001 went from 10% to 70% in 4 minutes and 30 seconds, and from 10% to 97% in 8 minutes and 40 seconds.
According to the comparison provided in the source, these figures surpass the performance of BYD’s 1,500-kilowatt network, which takes the Blade Battery 2.0 from 10% to 70% in five minutes, and from 10% to 97% in nine minutes.
Precise Pulses to Counter Lithium Plating
Geely links some battery degradation to repeated fast charging, as lithium ions can accumulate on the surface of the negative electrode instead of entering its structure. This phenomenon, known as lithium plating, gradually reduces usable capacity.
The company says its lithium-ion recovery through pulses technology sends precise currents through the cells to reactivate the accumulated ions. It has also developed a slow-charging strategy for nighttime home use, claiming that it gradually helps address some of the degradation caused by fast charging.
However, the 20% figure is not a guaranteed result for every vehicle; Geely’s own wording says “up to 20%,” making it a maximum result tied to test conditions, not a general promise of a fixed additional lifespan.
Predicting Heat Before It Occurs
The system uses the Xingrui PowerMind model, which Geely developed in cooperation with the Chinese artificial-intelligence startup StepFun. The model coordinates the vehicle, battery, charger, cloud, grid, and energy-storage system at the station.
Instead of reducing power after the battery temperature rises, Geely says the model predicts the temperature trend approximately 30 seconds in advance, then adjusts the current, cooling, and charging-session duration for each vehicle and battery. The company targets an average temperature of 55 degrees Celsius during charging, with a peak below 65 degrees.
To achieve this at 2,250 kilowatts, the station uses a five-point liquid-cooling system covering the energy-storage battery, charging unit, cable, charging port, and vehicle battery pack.
6C Battery for Lower-Priced Vehicles
The Shendun Golden Battery used in tests of the Lynk & Co 10 and Zeekr 001 supports a maximum charging rate of 12C. The Next-Gen Ultra Short Blade Battery intended for lower-priced models reaches 6C, and Geely says laser welding of the tabs and cell covers reduces the heat generated during charging by 10%.
Why Does This Matter?
The most important value in the announcement is not the power figure alone, but the attempt to address the trade-off between charging speed and battery degradation. If the results of the precise pulses are confirmed in independent, long-term tests, they could enable higher speeds without relying solely on reducing power to protect the battery. For now, however, the claims of extended lifespan remain tied to the company’s data, and the source has not provided sufficient details about the number of test cycles, measurement conditions, or how widely the results apply to different models.
