MAN eTGX bidirectional charging raises fleet energy-design questions

A SPIRIT-E trial demonstrated 350 kW truck-to-grid power export, prompting fleet buyers to assess battery, dwell-time and grid requirements.

TL;DR — three sentences

  • A SPIRIT-E trial exported up to 350 kW from a MAN eTGX with 480 kWh of usable energy to depot and public grids. (S1)
  • Project calculations identified average energy-cost savings of around 10% and savings up to 20% under optimal conditions. (S1)
  • Depot dwell time, annual mileage below 100,000 km and grid-connection capacity influence the economics. (S1)

What happened

The SPIRIT-E research project demonstrated that an electric truck can supply local or public electricity networks while also operating as a mobile energy store.S1 Technical University of Munich led the work with MAN Truck & Bus, Traton R&D and other partners, using a depot operated by Spedition Schmid in Regensburg, Germany.S1

Testing covered the MAN eTGX and mobile and stationary equipment supplied by SBRS, with the partners coordinating links among the vehicle, charger, operator software, site energy manager, electricity trader and grid operator.S1 The implementation used ISO 15118-20 for communication during charging and electricity discharge.S1

An eTGX with 480 kWh of usable battery energy exported electricity through a bidirectional DC charger at rates up to 350 kW, serving both the depot network and public grid.S1 The same truck also charged another vehicle from its battery in a vehicle-to-vehicle configuration.S1 A separate PowerBot test simulated purchasing electricity at lower prices and selling it at higher prices, while the Equigy platform demonstrated grid-balancing support.S1

The source says economics depend on duty cycles, mileage, dwell time, battery capacity, power prices, grid charges, local generation and grid-connection capacity.S1 Project calculations identified regular depot dwell and annual mileage below 100,000 km as favorable conditions, with average energy-cost savings around 10% and savings up to 20% under optimal conditions.S1 MAN Truck & Bus said it is working to bring the capability into series production and is developing customer consulting support.S1

XAIPART take

Technical impact

Design engineers should treat grid export as a site-infrastructure requirement rather than a vehicle-only feature. Charger rating, battery availability, communication compatibility, control software and grid-operator interfaces must be validated together.S1 The demonstrated ISO 15118-20 implementation provides a communications reference, but fleet-specific cybersecurity, dispatch priority and backup-power requirements were not disclosed.

Market impact

For procurement teams, the relevant value is the combination of fleet operation and energy trading rather than a standalone battery product. Site connection capacity, tariff exposure, charger availability and the number of hours a truck remains parked can determine whether the modeled savings translate into a usable business case; the source did not disclose charger pricing or production lead times.S1

Action

Request a site-level feasibility study covering route duty cycles, depot dwell windows, charger architecture, software control and grid limits. Compare the calculated energy savings with added charging hardware, connection work and operational constraints before specifying bidirectional-capable vehicles.S1

XAIPART Forecast

XAIPART expects at least one commercially documented MAN eTGX bidirectional-charging deployment to report grid-export capability of 100 kW or more within 12 months; if no qualified deployment reports at least 100 kW in that period, this forecast is wrong.XAIPART analysis
