Today, Huawei advanced the state of electric vehicle infrastructure, unveiling what it describes as the industry’s first fully liquid-cooled megawatt fast-charging solution at its “2025 Huawei Intelligent Electric & Intelligent Charging Network Launch Conference.”
The new charger boasts impressive specifications, including a peak power output of 1.5 megawatts and the ability to add 20 kWh of energy per minute. It can sustain a maximum charging current of 2400 amps for a continuous 15 minutes, enabling a 300 kWh battery pack, typical for heavy-duty applications, to achieve a full charge cycle in just a quarter of an hour. Huawei claims this represents a nearly fourfold improvement in replenishment efficiency compared to traditional fast-charging stations.
A key technological innovation is the charger’s immersive liquid cooling system. This design tackles the critical challenge of thermal runaway often associated with high-power charging, ensuring stable operation across a wide temperature range from -30°C to 60°C. Huawei states this enhances reliability, reducing the failure rate by 50% and extending the operational lifespan of the equipment to 15 years. The system incorporates Huawei’s self-developed Silicon Carbide (SiC) chips, which offer triple the energy density of conventional silicon-based components.
Intelligent features are also integrated, including an innovative power allocation algorithm that dynamically adjusts the output power, mitigating potential impacts on the electrical grid. The system supports Vehicle-to-Grid (V2G) interaction, allowing bidirectional energy flow. In collaboration with the State Grid, Huawei has developed an intelligent scheduling system to dynamically manage charging power and reduce peak grid load by up to 40%.
While developed with heavy-duty electric trucks in mind for high-frequency scenarios like ports and mines, Huawei has already collaborated with 11 automakers on over 30 compatible 4c ultra-fast charging truck models. The megawatt charger is compatible with passenger cars and construction machinery, offering plug-and-play functionality for an estimated 99% of existing EV models.
Real-world validation comes from a pilot project at Shenzhen’s Yantian Port, where electric heavy-duty trucks have successfully implemented a “charge 15 minutes, operate 4 hours” work cycle. This has reportedly led to a 35% reduction in operating costs compared to traditional diesel trucks.
Looking ahead, Huawei has forged strategic partnerships with major logistics players like SF Express and JD Logistics, planning an initial deployment of 5,000 electric heavy-duty trucks compatible with the new megawatt charging system. Furthermore, the company is actively participating in the development and refinement of megawatt-level charging protocols to help establish industry standards.
