Infineon Technologies recently announce that it will supply customized silicon-carbide (SiC) power modules to Electreon, a provider of wireless charging solutions for electric vehicles (EVs), for use in Electreon’s dynamic in-road charging systems. The technology enables EVs to charge wirelessly through inductive power transfer from copper coils embedded beneath the road surface. As vehicles travel over the coils, power is transferred from the grid to the vehicle without physical connectors.
Infineon’s SiC power modules are used to convert grid-supplied electrical energy for wireless battery charging in Electreon’s wireless electric road system (wERS). The system is designed for applications involving high-utilization vehicles, including buses, trucks, and other fleet EVs operating on highways, toll roads, ports, and transportation hubs such as airports.
Power transfer in the system reaches an average of approximately 200 kW, with peak levels exceeding 300 kW, using Infineon EasyPACK 3B CoolSiC 2000 V modules developed to meet Electreon’s system requirements. This performance was demonstrated during a recent deployment on France’s A10 highway, where dynamic wireless charging was tested with heavy and medium-duty trucks, buses, vans, and passenger vehicles while in motion.
By enabling continuous charging during operation, the system allows vehicles to maintain battery charge levels without relying solely on stationary charging infrastructure. This approach can support the use of smaller battery packs, reducing vehicle mass and increasing available payload capacity, which is a key consideration for commercial and fleet EVs.
Electreon has deployed systems incorporating Infineon’s customized SiC modules at test sites in the U.S., Germany, France, Norway, Portugal, Sweden, Italy, Israel, and Japan, with additional long-distance projects currently planned.
Silicon carbide–based power semiconductors are increasingly used in high-power EV charging and energy conversion systems due to their ability to operate at higher switching frequencies with lower losses than conventional silicon devices. These characteristics support higher efficiency, compact system design, and improved thermal performance in demanding transportation environments.
