Infineon boosts Electreon’s in-road charging performance with high-power SiC modules

A new step forward for dynamic charging infrastructure
Electreon’s wireless electric road system (wERS) has integrated customized silicon carbide (SiC) power modules from Infineon Technologies to enhance the performance and efficiency of inductive in-road charging for buses, trucks and other electric vehicles. The system embeds copper coils beneath the road surface, transferring energy from the grid to EVs while they drive, eliminating dependence on stationary charging stops.

The Infineon modules convert grid power into the high-frequency energy required for inductive transfer, enabling continuous charging along highways, toll corridors, ports and mobility hubs where heavy-duty transport operates at high duty cycles.

Higher power transfer through tailored SiC modules
The latest system generation increases average power transfer to around 200 kW, with peak values above 300 kW, using Infineon’s EasyPACK 3B CoolSiC 2000 V modules developed specifically for Electreon’s operating conditions.

This performance was demonstrated on France’s A10 motorway, the first highway where medium- and heavy-duty trucks, buses, vans and passenger vehicles can recharge while in motion. The ability to maintain state of charge during operation enables vehicles to use smaller battery packs, reducing acquisition cost, total weight and associated cargo limitations.

Electreon has already deployed Infineon’s customized SiC modules at test tracks in the U.S., Germany, France, Norway, Portugal, Sweden, Italy, Israel and Japan, with further integration planned for extended-distance projects.

SiC technology supports continuous high-power operation
Silicon carbide power semiconductors are widely used in high-power applications due to their ability to switch at higher frequencies with lower losses compared to silicon. Their thermal efficiency, robustness and ability to withstand high voltage levels make them suited to dynamic charging systems operating in harsh roadway environments.

In Electreon’s wireless-road architecture, Infineon’s SiC technology supports efficient energy transfer, minimizes conversion losses and contributes to compact power-electronics design along the roadside infrastructure.

Toward scalable adoption of wireless road charging
Dynamic charging solutions, particularly for commercial vehicles with high utilization rates, address operational constraints typical of freight and transit fleets. By reducing reliance on stationary charging stations, the system supports 24-hour operation and simplifies route planning, especially for logistics corridors or airport-to-depot shuttles.

Electreon’s deployment strategy focuses on regions with heavy traffic density, where continuous on-route charging can reduce energy downtime and accelerate the shift from diesel to electric drivelines. The combination of inductive charging infrastructure and high-performance SiC power modules represents a step toward scalable, grid-integrated EV energy ecosystems.
