Google’s self-driving cars could feature wireless charging

Google may be playing with wireless charging for its self-driving cars, suggest newly uncovered documents.

The documents, filed with the US Federal Communications Commission (FCC) last year and spotted by IEEE Spectrum, reveal applications and permissions for the installation of wireless chargers from Hevo Power and Momentum Dynamics at locations where Google is testing its driverless cars.

The wireless charging systems from both companies use a receiver attached to the vehicle to charge it as it goes over plates placed on a driveway or road. Essentially, the system works similar to a phone or wearable wireless charger, just on a much larger scale.

Hands-free charging

Wireless charging systems for vehicles are usually set up in driveways at the home or office so cars can charge over a period of time. More recently, however, there trials are being conducted where the charging plates are embedded into roads or highways so electric vehicles can charge wirelessly while you drive.

In addition to being incredibly novel, wireless charging might be the perfect system for Google’s self-driving cars: the vehicles may end up intended not as purchases for individuals but rather a public transport or fleet-type solution, and wireless charging could them on the road without having to stop for a person to plug them into a charging station.

Still, it’s unclear if Google is testing Hevo Power and Momentum Dynamics as an on-road wireless charging solution or if the cars would need to parked in order to be charged. Either way, it’s clear that Google wants to make driving as much of a hands- and wire-free experience as it can.
