Starting point – Mobile high-power charging in weak-grid environments
Electrifying heavy-duty operations often requires temporary or mobile energy solutions that can deliver high DC power independently of local grid limitations. These applications place strict requirements on power electronics, control, safety, and system reliability.
For the THOR mobile power unit, the challenge was to ensure predictable high-power performance while maintaining a compact, mobile form factor suitable for harsh operating environments.

Proven delivery track record
Hevtec has delivered 85 CCS charging systems since 2022, when the collaboration with Kverneland Energi began.
Solution – Power and control integration for the THOR mobile energy unit
Hevtec supported the THOR solution by contributing to the power and control system integration of the mobile energy unit.
THOR is a mobile power package featuring:
400 kW DC output
291 kWh battery capacity
Designed for high-power charging where grid access is weak or unavailable
Hevtec’s role focused on system-level integration to ensure that power delivery, control, and operational behavior meet the requirements of demanding heavy-duty charging use cases.
"Working with Hevtec has been a smooth and positive experience. We appreciate the collaborative mindset and the shared focus on quality throughout the process."
