Scania demonstrates vehicle-to-grid with Megawatt Charging System for heavy transport

Scania has successfully demonstrated one of the world's first vehicle-to-grid (V2G) implementations for heavy commercial vehicles utilizing the Megawatt Charging System (MCS). This marks a significant step toward integrating heavy electric transport into the broader energy system, enabling battery-electric trucks to support the power grid.

The V2G demonstration showcased how trucks can serve as a flexible resource for the grid, offering services such as peak shaving, grid balancing, and energy storage when parked. As the electrification of heavy transport accelerates, the need for grid flexibility increases. Large-scale charging of electric trucks presents new demands on local grids, but also represents substantial mobile battery capacity.

"Electric trucks will not only consume electricity, they can also become an active resource in the energy system," said Tobias Ejderhamn, Global Manager, Transformation & New Business, Scania. "This shift transforms the fleet operator’s role from solely providing transport services to also offering energy flexibility." The demonstration utilized MCS, the next generation of ultra-fast charging technology, which is expected to be crucial for enabling long-distance electric transport and future energy services like V2G.

The system facilitates real-time communication between the truck, charger, and energy management systems, allowing for dynamic control of charging and discharging based on transport needs and grid conditions. Yorben Muller, Product Manager Charging for TRATON, highlighted the significance of combining megawatt charging with intelligent energy management. "To our knowledge, this is one of the world’s first demonstrations of vehicle-to-grid functionality using MCS for heavy commercial vehicles," Muller stated. The technology is seen as a way to enhance the business case for electric trucks by creating new revenue streams and improving asset utilization.
