What Happened
MAN Truck & Bus, together with partners in the NEFTON project, has successfully operated a high-current vehicle charging path at 3,000 amperes on a test bench. This achievement marks a step toward megawatt charging, potentially enabling charging powers of up to three megawatts. The tests at TU Munich and Fraunhofer ISE provided data on thermal behavior, cooling, and safety for future charging systems.
MAN eTGX demonstrated with 1 MW charging power.
3,000 amperes achieved on test bench, paving way for 3 MW charging.
The high current requires optimized components with minimal electrical resistance and liquid cooling for cables, connectors, and distributors. However, achieving over 1 MW in practice will require a new generation of battery systems designed for high charging rates. The TRATON Group will continue the work after the project, focusing on series-ready high-current paths and bidirectional charging.
Why this matters
This breakthrough could cut charging time for eTrucks to 10-15 minutes for 400 km range, making electric long-haul transport more viable.
