Wireless EV Charging Stations To Roll Out On 500 Major Highways

Why Wireless Charging on Highways Matters

Electric vehicles (EVs) are moving from niche to mainstream in India, with sales hitting a record 1.2 million units in 2023. Yet the biggest hurdle for many owners remains the need to pause at a charging point during long drives. Wireless charging eliminates that stop, allowing drivers to keep moving while their battery recharges underneath the road. The recent decision to deploy wireless stations on 500 major highways is a game‑changer for the industry and for commuters alike.

How Wireless Charging Works

At its core, wireless charging uses electromagnetic induction. A transmitter coil embedded in the road sends a magnetic field to a receiver coil inside the vehicle. When the two are aligned, energy flows across the gap without any physical connector. The process is similar to the way a phone charger wirelessly powers a smartphone, but scaled up for the weight and power of a car.

There are two main types of wireless systems used on highways:

• Resonant Inductive Coupling: The transmitter and receiver coils are tuned to the same frequency, allowing efficient power transfer over a few centimeters. This is the technology chosen for most highway projects because it can deliver up to 22 kW per vehicle.
• Power Line Coupling: A less common approach that uses the electrical supply line to feed power directly to the vehicle. It is more complex but can support higher power levels.

Deployment Strategy for 500 Highways

The rollout plan covers 500 major corridors that span from Delhi to Mumbai, Bengaluru to Kolkata, and Chennai to Hyderabad. Each corridor will host a series of charging lanes that run alongside the main carriageway. Drivers can keep their wheels on the road while the system recharges the battery at speeds that match the vehicle’s consumption rate.

Key elements of the deployment include:

• Infrastructure Integration: The transmitter modules are embedded in concrete slabs, protected by layers of reinforced steel and a waterproof sealant to withstand heavy traffic and weather.
• Vehicle Compatibility: Manufacturers such as Tata Motors, Mahindra Electric, and Hyundai have already added receiver modules to their latest models. The system can also be retrofitted to older vehicles with an aftermarket kit.
• Smart Grid Connectivity: Each charging lane connects to the local grid and a central management system that monitors power usage, vehicle detection, and fault conditions in real time.

Benefits for Drivers and the Environment

For a daily commuter on the Mumbai‑Pune corridor, the ability to recharge while driving saves 30–45 minutes that would otherwise be spent at a charging station. This reduces idle times and improves overall fuel efficiency. In rural areas, where charging points are scarce, the wireless lanes will open up new travel routes for EV owners.

From an environmental standpoint, continuous charging means batteries stay within an optimal state of charge, which can extend their lifespan and lower the need for replacements. The reduction in idling also cuts down on local air pollution, a significant benefit in densely populated regions.

Real‑World Pilot in Bengaluru

In 2022, the state of Karnataka launched a pilot on a 3 km stretch of the Outer Ring Road. Over the course of six months, more than 10,000 vehicles used the wireless lanes, with an average charging rate of 15 kW. Drivers reported a noticeable decrease in battery anxiety, and the local transport department noted a 12 % drop in average travel time for EVs on that route.

One resident, Priya, a delivery rider, shared, “Before the pilot, I had to stop at a charging station every 150 km. Now I can keep going, and the battery levels stay steady. It’s a relief.”

Challenges and How They’re Being Addressed

While the benefits are clear, several hurdles remain:

• Initial Cost: Embedding coils into existing roadways requires significant upfront investment. The government is partnering with private firms under a public‑private partnership model to spread costs over the lifespan of the infrastructure.
• Standardisation: With multiple manufacturers, ensuring that all vehicles can communicate with the charging lanes is critical. The Indian Institute of Technology (IIT) Delhi is working on a national standard that aligns with ISO 15118.
• Maintenance: Roadworks and heavy trucks can damage the transmitter modules. A predictive maintenance system using vibration sensors is being trialed to spot wear before it leads to a fault.

Future Outlook: Beyond 500 Highways

The 500‑highway rollout is the first step. The next phase aims to extend wireless charging to urban arterial roads, metro corridors, and even toll plazas. In cities like Delhi and Chennai, plans are underway to embed charging lanes in ring roads that connect multiple city buses and ride‑share fleets.

As battery technology improves, the power required per vehicle will drop, making wireless solutions more economical. Meanwhile, the rise of autonomous vehicles will demand seamless energy delivery, and wireless charging will fit naturally into that ecosystem.

What You Can Do Now

If you own an EV, check whether your model has a built‑in receiver. If not, look into aftermarket kits that can be installed by certified technicians. Keep an eye on the local transport department’s updates—new lanes are announced monthly, and some routes already have temporary test tracks.

For fleet operators, the wireless system offers a way to reduce downtime and improve route efficiency. Investing in compatible vehicles now can pay off once the network expands.
