Huawei unveiled a new fully liquid-cooled supercharger with a peak power output of 1.5 megawatts, as competition escalates among Chinese companies to develop ultra-fast charging solutions for electric vehicles (EVs).
The new charger, introduced in Shanghai, is designed primarily for heavy-duty electric trucks, though Huawei said it is also compatible with passenger vehicles. The company claims the unit is the industry’s first MW-class supercharging solution with full liquid-cooling capabilities.

According to Huawei, the charger can deliver up to 2,400A of current when using two charging guns simultaneously. In a demonstration, the system charged a heavy-duty electric truck from 10% to 90% in just 15 minutes, delivering approximately 300 kilowatt-hours—almost four times faster than conventional fast chargers.
The supercharger utilizes immersion liquid-cooling technology, offering a projected service life of 10 years and stable performance in temperatures ranging from -30°C to 60°C. Huawei said the system supports 99% of existing EV models and can increase charging efficiency by 30% while reducing operating costs by 20% in practical applications.

As part of its rollout, Huawei has entered into strategic agreements with logistics firms SF Express and JD.com to deploy 5,000 electric heavy trucks compatible with its MW-class charging system. The company also announced partnerships with 11 automakers to co-develop more than 30 truck models with 4C supercharging capability, targeting operations in ports, mines, and other high-demand environments.
The launch comes amid a broader industry push in China to boost EV charging speeds. On Thursday, battery giant CATL revealed its second-generation Shenxing Superfast Charging Battery, capable of peak charging power up to 1.3 MW and a charging rate equivalent to 2.5 kilometers of range per second.

Earlier this year, Zeekr announced plans to release a 1.2 MW fully liquid-cooled charger in the second quarter, while BYD unveiled a 1 MW supercharger in March that can add 400 kilometers of range in five minutes.
Huawei’s entry into the ultra-fast charging space underscores the intensifying arms race among Chinese tech and auto firms seeking to alleviate charging bottlenecks and enhance the usability of electric vehicles for both commercial and private use.
