April 11, 2025 | Beijing — Chinese energy technology company Sunwoda has introduced the world’s first 10-meter-class, 2MWh liquid-cooled mobile energy storage vehicle at ESIE 2025.
The new vehicle features 314Ah high-energy-density battery cells, providing a total storage capacity of 2MWh, which is three times the capacity of traditional mobile energy storage systems. It is also equipped with an 800kW power conversion system (PCS), offering a power output increase of 220%.
The system uses liquid cooling technology for the first time in a mobile energy storage vehicle. By employing glycol coolant and an optimized thermal pipeline layout, it ensures precise temperature control for individual battery cells, enhancing charging/discharging efficiency and extending the lifespan of the system.
In terms of safety, the vehicle includes a six-layer protection system, covering the battery cells, modules, system, and vehicle as a whole, ensuring safety during operation.
The vehicle has already completed a 5,000-kilometer endurance test, covering over 20 cities and various terrains across China. After passing extensive testing and receiving certification, mass production is planned to begin in May 2025.
This mobile energy storage system is expected to be used in a variety of scenarios, including grid maintenance without power outages, emergency power supply for disaster relief, power assurance for large events, highway rescue, and charging services.
