Geely Auto Group has unveiled a new electric-vehicle battery capable of accepting charging power of up to approximately 1,100 kilowatts, alongside the launch of a 2.2-megawatt charger at an event held in the Chinese city of Ningbo. The company says the station can supply two vehicles with megawatt-level power simultaneously, while some vehicles belonging to the group can use peak power of approximately 1,100 kilowatts.
In a test presented by the company, a Lynk & Co 10 was charged from 10% to 97% in 8 minutes and 40 seconds. This result exceeds the stated peak capabilities of vehicles such as the Lucid Gravity and Porsche Cayenne Electric, which stand at 400 kilowatts, while the upcoming Mercedes-AMG GT reaches 600 kilowatts. However, the high speed creates a direct engineering challenge, because heat and lithium accumulation can accelerate cell degradation.
How Is Geely Trying to Protect the Battery?
Geely said the Ultra Short Blade Battery uses cells with two basic lengths, 395 and 370 millimeters, instead of the 580-millimeter cell currently used by the company and the approximately 960-millimeter length it described as common in the industry. According to the company’s explanation, reducing the distance traveled by ions inside the cell lowers internal resistance and the heat generated during charging and discharging.
The company also made modifications to the cathode and anode structure to limit the phenomenon of lithium deposition on the anode surface. This phenomenon can lead to the growth of so-called lithium dendrites, increasing the risk of an electrical short circuit or permanent damage to the cell. It also added a technology called “lithium pulse restoration,” which uses a precise pulse current at a specific frequency to reduce the accumulation of ions on the anode surface.
To manage heat, the battery uses a five-point liquid-cooling system that coordinates the on-site energy-storage battery, the power unit, the charger, the charging port, and the vehicle’s battery. The AI-supported Xingrui PowerMind system predicts the battery temperature 30 seconds in advance and adjusts charging speed in real time. Geely says the design targets an average temperature of 55 degrees Celsius, with a maximum limit of 65 degrees Celsius.
What Changes in Practice?
Geely increased the battery warranty from 8 years or 150,000 kilometers to 8 years or 200,000 kilometers, signaling its confidence in the new design’s ability to withstand use. However, the warranty alone does not prove the battery’s performance over years of repeated charging at megawatt-level power, particularly since this technology began spreading commercially on a broad scale in China only last year.
The article notes that battery degradation does not depend solely on charging power, but is also affected by driving behavior, charging habits, climate, and battery design. An independent test involving a BYD Fangchengbao Tai 3 also recorded a peak temperature of 76.42 degrees Celsius, higher than the reading displayed by the vehicle, illustrating the need for independent and consistent measurements.
Editorial reading: The actual change here is not merely an increase in charging power, but an attempt to redesign the cell, cooling system, and software controls together to address the cost of speed to service life. Nevertheless, Geely’s claims remain based on company data and a single demonstration test, while assessing long-term reliability requires years of use and independent data. The technology therefore appears promising for electric-vehicle users focused on reducing downtime, but its practical limits will not become clear before it is tested under varied driving, climate, and charging conditions.
