Geely unveils ultra-fast charging: 10–70% in 4.5 min
Published Date :
Geely Auto Group introduces new AI-powered Smart Charging technology combines a 2,250 kW charging station with 12C battery capability, reaching 10–70 per cent in 4 minutes 30 seconds and 10–97 per cent in 8 minutes 40 seconds in real-world tests
Chinese automaker Geely Auto Group has unveiled its next-generation Geely Smart Charging technology, combining ultra-high-power charging hardware, artificial intelligence and new battery technology to reduce charging times while managing heat and battery degradation. In what Geely describes as real-world tests, batteries used in the Lynk & Co 10 and Zeekr 001 charged from 10–70 per cent in 4 minutes 30 seconds and from 10–97 per cent in 8 minutes 40 seconds — the company’s fastest production-ready charging performance to date. The Wall Street Journal highlighted the announcement as part of the intensifying ultra-fast charging battle between Chinese automakers, including BYD, as manufacturers compete to reduce charging times.
2,250 kW charging station
The technology debuts alongside Geely’s fifth-generation Smart Charging Station, capable of delivering peak charging power of up to 2,250 kW, as well as a new generation of battery technology.
The 2,250 kW figure refers to the charger’s peak capability rather than the power necessarily accepted continuously by a vehicle.
Geely’s Shendun Golden Battery, developed for ultra-fast charging and high-performance applications, supports a peak charging rate of 12C.
AI predicts battery temperature
At the heart of the system is Xingrui PowerMind, a smart energy AI model jointly developed by Geely Auto Group and StepFun.
The system coordinates the vehicle, battery, charging station, cloud, grid and energy-storage system, allowing charging conditions to be adjusted dynamically.
Algorithms can predict battery-temperature changes up to 30 seconds in advance and adjust charging power accordingly. Geely says the system is designed to keep average battery temperature below 55°C and peak temperature below 65°C during fast charging.
Thermal management is supported by what Geely describes as an industry-first five-point liquid-cooling system, covering the charging-station energy-storage battery, charging pile, cable, charging port and vehicle battery pack.
Designed to reduce fast-charging degradation
Geely is also using AI to address battery degradation associated with repeated ultra-fast charging.
Xingrui PowerMind can tailor charging strategy for each vehicle and battery by adjusting peak current, cooling intensity and charging duration in real time.
Geely has also developed lithium-ion pulse restoration technology, which uses micro-pulse currents to reactivate lithium ions accumulated at the negative electrodes during repeated fast charging.
The company claims combining AI charging management with battery-restoration technology can increase battery cycle life by up to 20 per cent. For home charging, Geely has developed a low-rate charging strategy designed to gradually mitigate degradation from repeated fast charging and protect battery cells over their lifecycle.
New 6C Ultra Short Blade Battery
Alongside its 12C high-performance battery, Geely introduced a next-generation Ultra Short Blade Battery aimed at improving longevity, safety and charging performance.
Geely-developed laser-welding technology for the cell tabs and covers is claimed to reduce heat during charging by 10 per cent, while the battery’s peak charging rate rises to 6C.
China’s ultra-fast charging race intensifies
Geely’s announcement places it firmly in China’s increasingly competitive ultra-fast charging race, with manufacturers including BYD pushing to reduce charging times.
The significance goes beyond the headline 4.5-minute figure. Geely is combining a 2.25 MW charger, 12C battery technology, predictive AI thermal management, five-point liquid cooling and battery-restoration technology in an effort to deliver very high charging rates while managing heat, safety and long-term battery health.
The quoted performance remains dependent on compatible vehicles, batteries and ultra-high-power charging infrastructure, while Geely describes the Lynk & Co 10 and Zeekr 001 results as real-world tests.
