Scania Pioneers World’s First V2G Through MCS for Heavy Electric Transport

On May 26, 2026, Scania announced the successful demonstration of one of the world’s first vehicle-to-grid (V2G) implementations for heavy-duty commercial vehicles using Megawatt Charging System (MCS) technology. The milestone highlights how battery-electric trucks can serve not only as transportation assets but also as valuable resources for the broader energy grid.

The demonstration showcased bi-directional charging, enabling electricity to flow both into and out of a truck’s battery. This capability allows electric trucks to provide energy flexibility services such as peak shaving, grid balancing, energy storage, and support for renewable energy integration.

As heavy-duty transportation continues to electrify, the demand placed on local power grids is expected to increase. At the same time, electric trucks represent substantial mobile battery capacity that often remains unused while vehicles are parked. Vehicle-to-grid technology creates an opportunity to leverage that stored energy, helping utilities and fleet operators better manage electricity demand.

“Electric trucks will not only consume electricity, they can also become an active resource in the energy system,” says 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.”

“What makes this significant is not only the bi-directional energy flow itself, but the ability to combine megawatt charging with intelligent energy management,” says Yorben Muller, Product Manager Charging, TRATON. “To our knowledge, this is one of the world’s first demonstrations of vehicle-to-grid functionality using MCS for heavy commercial vehicles. The truck, charger and energy system can communicate with each other in real time, creating the foundation for heavy electric vehicles to become active and controllable assets in the energy system.”

Scania’s demonstration utilized the Megawatt Charging System, a new ultra-fast charging standard designed specifically for heavy commercial vehicles. MCS is expected to play a critical role in enabling long-haul electric trucking while supporting future energy services.

The system incorporates secure, real-time communication between the vehicle, charger, and energy management platform, allowing charging and discharging to be dynamically adjusted based on fleet requirements and grid conditions. The demonstration included bi-directional charging through MCS, backend-controlled energy management, integration with external charging and energy systems, and two-way energy transfer through the charging equipment.

“The ability to combine high-power charging with intelligent and secure energy management could also strengthen the business case for battery electric trucks by creating new ways for fleet operators to optimise energy usage and lower their operational costs,” adds Ejderhamn.

For fleet operators, the technology could lower energy costs, improve depot energy management, maximize the use of locally generated renewable electricity, and create opportunities to participate in emerging energy flexibility and grid-balancing markets. Charge point operators and energy providers may also benefit through improved utilization of charging infrastructure and available grid capacity.

The demonstration achieved charging and discharging rates of up to 1,000 amps and 750 kilowatts. According to Scania, it represents one of the first known demonstrations of bi-directional power transfer through MCS for heavy-duty electric trucks. Initially, the technology is expected to be most valuable in depot environments, where vehicles remain parked for extended periods and energy usage can be optimized around grid demand.
