Eradicating Range Anxiety Forever
The Indian tech capital of Bengaluru has added another feather to its cap by inaugurating the world’s first fully operational wireless EV charging highway. The 50-kilometer stretch, connecting the city center to the international airport, utilizes revolutionary inductive charging technology embedded directly beneath the asphalt. This infrastructure allows electric vehicles (EVs) to charge their batteries continuously while cruising at highway speeds.
The Technology Beneath the Tarmac
The project, a joint venture between the Ministry of Road Transport and several deep-tech startups, relies on magnetic resonance induction. Specially designed copper coils are laid under the road surface, transmitting electricity seamlessly to receiver pads installed on the undercarriage of compatible EVs.
Impact on Logistics and Daily Commutes
- Continuous Power: Vehicles equipped with the receiver pads can theoretically drive indefinitely on this stretch without ever stopping at a plug-in charging station.
- Smaller Batteries: Automakers are excited because this technology means future EVs can be manufactured with much smaller, lighter battery packs, significantly reducing the initial purchase price of the cars.
- Commercial Viability: The highway is expected to revolutionize urban logistics, allowing electric delivery trucks and public transport buses to operate 24/7 without downtime for recharging.
To use the infrastructure, vehicle owners must subscribe to a digital tolling system that calculates the exact amount of kilowatt-hours consumed during the drive, billing them automatically via their connected Fastag accounts. Several other metro cities are already drawing up blueprints to replicate this success.
