Sunwoda, the Chinese energy company, has showcased a new mobile energy storage system (MESS) which can be fitted into vehicles.
The ESS was revealed at the 13th Energy Storage International Summit & Exhibition (ESIE 2025) and is said to start being mass produced in May 2025.
The MESS vehicle is claimed to have a capacity of 2MWh, and to be the first 10-metre-long vehicle of its kind with an ethylene glycol-based liquid cooling system, it said.
Its MESS vehicle solution is aimed for usage in a diverse range of scenarios, including:
- Power grid maintenance
- Disaster relief and rescue
- Power assurance for events
- Mobile changing scenarios
- Temporary power for construction
The vehicle has reportedly been tested over 5000km according to the firm.
The vehicle will be made up of 40 smaller batteries in the cargo box of the vehicle, which will consist of Sunwoda’s self-developed 314Ah lithium-ion battery.
This battery is said to have three times the capacity of other MESS’ like it.
It is claimed to be able to reach a lifespan of 6000 cycles whilst lowering the total operational costs by 15-20% compared to conventional diesel generators, according to ESS News.
The MESS is claimed to have the capability of switching between being grid-connected and off-grid in under 20 milliseconds. This is to ensure seamless delivery of electricity.
The firm has told ESS News that it has already received some potential orders but has not disclosed further details yet.
