Imagine a world where electric vehicles don't need to stop to recharge. Where buses, trucks, and cars charge simply by driving over specially equipped roads. This isn't science fiction anymore—it's happening right now on France's A10 highway, and it's reshaping how we think about EV infrastructure.

The Breakthrough: Infineon & Electreon Partnership
On December 3, 2025, Infineon Technologies announced it's supplying customized silicon carbide (SiC) power modules to Electreon, a wireless charging pioneer. Together, they've achieved a major milestone: delivering 200 kilowatts (kW) average power, with peaks exceeding 300 kW through copper coils embedded beneath the road surface.
For context, that's comparable to the fastest DC fast chargers available today—but without drivers needing to stop at a station.

How It Works
The technology is elegantly simple. Copper coils are embedded beneath the road surface at strategic points. As vehicles equipped with receiving coils drive overhead, power transfers wirelessly via electromagnetic induction. The system activates automatically when a vehicle is positioned above the coils. Think of it like an EV charging lane that energizes only when needed.
On the 1.5-kilometer stretch of the A10 highway southwest of Paris, prototype trucks, buses, utility vans, and passenger cars are already charging while driving in live traffic. Early results confirm the system reliably delivers over 300 kW of instantaneous power—a real-world validation that this technology works under real conditions.

The Game-changing Advantage：Smaller Batteries
Here's why this matters for operators and fleet managers: continuous on-route charging means vehicles don't need massive batteries anymore. Smaller battery packs translate to significant advantages:
Lower vehicle costs: Battery packs represent 30-40% of EV purchase price. Smaller batteries reduce that dramatically..
Reduced weight: Lighter vehicles carry more cargo. Delivery companies get more payload per vehicle without exceeding weight limits.
Less grid strain: Fewer oversized batteries charging simultaneously reduces peak demand on electrical grids. It's a win for utilities managing grid capacity.
Lower emissions: Smaller batteries require less rare earth mining and manufacturing energy—reducing the vehicle's entire carbon footprint.
For a delivery company operating 100 trucks, the weight savings and reduced battery costs could translate to millions in operational savings annually.

Global Expansion Already Underway
France's A10 is just the beginning. Electreon has incorporated Infineon's silicon carbide technology into test tracks across nine countries: the USA, Germany, France, Norway, Portugal, Sweden, Italy, Israel, and Japan. The company has 100+ global partners, including Toyota, Ford, IVECO, and Kenworth.
Plans for longer-distance projects are already in motion. If successful at scale, thousands of kilometers of European and North American highways could be transformed into dynamic wireless charging corridors.

The Operator's Perspective
For EV charging companies, this technology represents both opportunity and disruption. Here's what's important to understand.
Complementary, not replacement: Wireless in-road charging won't eliminate stationary fast chargers. Instead, it complements them. The A10 system handles continuous topping-up during highways. Stationary chargers handle quick top-ups in urban areas and at rest stops..
Fleet-focused revenue: The biggest near-term opportunity is commercial fleets—delivery companies, buses, and trucks. These vehicles operate predictable routes on fixed highways. Installing wireless infrastructure on high-traffic corridors serving ports, logistics hubs, and major freight routes creates a captive revenue stream.
Infrastructure investment model: Unlike traditional chargers—which are discrete assets you place at specific locations—wireless highways are linear infrastructure. Operators could partner with toll roads, highway authorities, and logistics companies for shared infrastructure investment and revenue sharing.

The Real Innovation: Silicon Carbide Technology
The secret sauce here is Infineon's silicon carbide (SiC) power modules. SiC semiconductors switch electricity at higher frequencies with lower energy loss than traditional silicon. This means:
• More power transferred with less waste heat
• More compact system design
• Better reliability under extreme conditions
• Faster charging transfer rates

What’s Next
Real-world highway testing is happening now. Scalability is the remaining question—not "if" this works, but "when" and "at what cost" can it be deployed at continental scale.
If the technology proves economically viable at scale, we're looking at a fundamental shift in EV infrastructure. Instead of building thousands of individual charging stations, utilities and operators could retrofit highways with charging lanes. Vehicles could travel farther with smaller batteries. Fleets could eliminate charging downtime entirely.
The future of EV charging isn't about faster plugs or higher power outputs. It's about roads that charge. That future just became real on the A10.
