Peer-to-peer highway EV charging would use telescoping cables between moving cars

Imagine a future where your EV was getting low on charge ­on a highway road trip – so you deploy a telescoping charging cable to another EV and borrow a few kilowatt-hours. An engineering professor at the University of Florida believes it’s not far-fetched.

We’ve seen a host of mobile EV charging van concepts. And there are proposed solutions for stationary robots to connect a vehicle to a charger, like what Kuka Robotics demonstrated last year (shown above).

The new idea is to merge the two so EVs on the move can connect with one another and with mobile charging stations. (Apple filed a patent for something similar in 2018.)

A few weeks ago, Swarup Bhunia and his colleagues at UoF’s electrical and computer engineering department posted a paper explaining how it would work. Here’s part of the Abstract:

We propose Peer-to-Peer Car Charging (P2C2), a highly scalable novel technique for charging EVs on the go with minimal cost overhead. We allow EVs to share charge among each other based on the instructions from a cloud-based control system.
