Scania demonstrates vehicle-to-grid through Megawatt Charging System for heavy electric vehicles

Scania has successfully showcased a vehicle-to-grid (V2G) system tailored for heavy electric commercial vehicles, utilising the Megawatt Charging System (MCS). This bidirectional charging technology allows electric truck fleets to not only draw power but also supply electricity back to the grid, supporting services such as peak shaving, grid balancing, and energy storage. The demonstration involved charging heavy vehicles at rates reaching 750 kW, highlighting the system’s capability to handle high power transfer efficiently within depot environments. The implementation of V2G technology is particularly promising for depot operations, where vehicles remain parked for extended periods, allowing charging and discharging to be synchronised with grid demands and renewable energy availability. By integrating local solar power generation and enabling more flexible grid connections, fleets can optimise energy use and contribute to grid stability. Scania’s system facilitates secure, real-time communication between trucks, chargers, and energy management platforms, ensuring dynamic control of energy flows based on transport schedules and grid conditions. Key figures from Scania and its parent company TRATON emphasised the transformative potential of this technology. Tobias Ejderhamn, Scania’s Global Manager of Transformation & New Business, noted that electric trucks could evolve from mere electricity consumers into active participants in the energy system, offering new flexibility services. Yorben Muller, Product Manager of Charging at TRATON, highlighted the significance of combining megawatt charging with intelligent energy management, enabling heavy electric vehicles to become controllable assets that can respond dynamically to energy system needs. The successful demonstration marks a significant step towards integrating heavy electric vehicles into broader energy networks, potentially reshaping the role of fleet operators. By leveraging V2G capabilities, operators could unlock additional value streams beyond transport, contributing to grid resilience and facilitating the uptake of renewable energy. As the technology matures, its deployment in depot settings may pave the way for wider adoption across the commercial transport sector, aligning with broader decarbonisation and energy transition goals.
