Study shows electric vehicles could be charged on the go via peer-to-peer system

Every day, Americans see more battery-electric vehicles (BEVs) on the road. According to Fortune Business Insights, the market for electric vehicles in the U.S. is expected to grow from $28.24 billion in 2021 to $137.43 billion in 2028. [...]

However, one drawback has made some consumers wary of purchasing a BEV — limited range. Unlike those plentiful gas stations, charging stations for EVs still can be few and far in between, and recharging a BEV's lithium-ion battery might take hours, making EVs impractical for some long-range road trips.

Now, a researcher at the University of Kansas School of Engineering has co-written a study in Scientific Reports proposing a peer-to-peer system for BEVs to share charge among each other while driving down the road by being matched-up with a cloud-based control system.

[...] A cloud-based system would match the two BEVs in the same vicinity, likely along major interstates. Like bicyclists in a Peloton, the two matched cars could travel close together, sharing charge en route with no need to stop for hours at a charging station. The cars would drive at the same locked speed while charging cables would link the vehicles automatically.

[...] "We'd have a complete cloud-based framework that analyzes the charging state of all participating vehicles in the network, and based on that the cloud tells you, 'Hey, you can actually pair up with this car which is nearby and share charge,'" Hoque said. "All of this has to be controlled by cloud infrastructure, which has algorithms to efficiently charge all the different BEVs."

[...] Hoque said the initial setup of a peer-to-peer charging infrastructure likely would require support from a major manufacturer of BEVs but then could expand organically.

"People who have electric vehicles will have this incentive of selling charge and earning extra money — these two things will work in parallel to grow this idea," he said.

    Sure, we all want a car that we can hop in in Miami and drive to Vancouver non-stop on a single charge

    We do? What kind of stimulants are you taking that you're okay with 52 hours straight of driving, and where can I get some?

    I drove Manhattan (New York)->Coral Gables (Miami) in 22.5 hours once... didn't intend to initially, but around Myrtle Beach I changed my mind about stopping for the night. Somewhere around Jupiter, FL I started seriously regretting the decision, but by then it was too late - too close to the goal to quit then.

    Of course, in the brave new world of self-driving cars, we'll just lay the seats flat for the night shifts.

      You probably made pit stops in amongst those 22.5 hours though, right? I know I couldn't drive more than 6 hours at a time without getting out to stretch my legs and wake up.

        Took a 45 minute meal break somewhere in the afternoon, obviously stopped for gas more than once, mostly just snacked on the road otherwise, but the last hour into Miami I did stop a few times to get out and jog around the car to make sure I wasn't falling asleep.
