Heavy electric trucks are getting closer to multi-megawatt charging
Short note, about 5 minutes to read.
What happened
High-power charging for electric trucks is not new. What is changing is the ability to move from charging at hundreds of kilowatts towards megawatt-scale charging, while research is beginning to test the complete systems needed to go further.
High-power truck charging → megawatt-scale charging → multi-megawatt system testing
Recent demonstrations in Europe have shown Megawatt Charging System infrastructure delivering up to 1.2 megawatts alongside battery-electric long-haul trucks operating in commercial transport conditions. The work forms part of wider research into how megawatt-scale charging can support heavy vehicles without requiring impractically long charging stops.
Independently, researchers at Fraunhofer Institute for Solar Energy Systems ISE, working with Technical University of Munich and other partners through the NEFTON project, have tested the complete charging path for an electric truck at currents of up to 3,000 amperes. The tests covered the system from charging cable and connector through the electrical distribution equipment to the vehicle batteries, under conditions designed to prepare charging systems for power levels beyond today’s roughly one-megawatt state of the art.
Together, these developments suggest that heavy-truck charging is moving beyond individual high-power demonstrations towards megawatt-scale operation and testing of the complete systems required for substantially higher charging power.
Why this matters
Heavy electric trucks need large amounts of energy to travel long distances while carrying substantial loads.
Recharging those batteries can take considerable time. Increasing charging power could allow much more energy to be transferred during the periods when trucks are already stationary, reducing the amount of additional time charging adds to their journeys.
For long-distance freight, this could make it easier to fit electric charging around the operating schedules of trucks and drivers rather than requiring long additional stops simply to replenish energy.
Who should care
- Truck manufacturers and fleet operators
- Logistics and freight companies
- Electric-vehicle charging companies
- Utilities and electricity-network operators
- Motorway and freight-infrastructure providers
- Governments developing heavy-vehicle charging networks
- Investors tracking transport and energy infrastructure
What could change over the next 2 to 3 years
Further testing could show whether charging at these power levels can operate reliably across different truck batteries, charging equipment and repeated charging cycles.
The more important next step will be moving from individual demonstrations and research facilities towards charging systems that can operate routinely at freight depots, motorway charging locations and other places where heavy vehicles already stop.
What might block this
Transferring very large amounts of power in a short period creates substantial engineering challenges, including heat, electrical losses and the need for components capable of safely handling very high currents.
Charging several trucks at these power levels could also create large local demands on electricity networks, requiring substantial grid connections and potentially additional energy infrastructure at charging locations.
Most importantly, demonstrating megawatt-scale charging and testing systems designed for still higher power does not yet show that these charging levels can be delivered economically and reliably across large commercial truck fleets.
Why I am sharing this
Electric-truck charging has been moving towards higher power levels for years. Recent developments are beginning to show megawatt-scale charging in heavy-vehicle environments while researchers test the complete systems needed to move beyond today’s charging levels.
If those systems can eventually operate reliably in everyday freight operations, much larger amounts of energy could be transferred during the periods when trucks are already stopped.
That could make charging time less of a constraint on how some long-distance electric trucks operate.
