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.

I think you meant that jokingly, but it is definitely true. More and more vehicles offer V2H (vehicle-to-home) power flow. Power companies have already proposed this as a solution to the storage problem. All those people with 70kwh batteries in their garages - why not use them for load smoothing?
The problem, of course, is that those batteries are mostly connected overnight, whereas the load peaks generally occur during the day. Still, it is one potential factor to consider.
Everyone is somebody else's weirdo.

I'm not joking. What will be a joke is the inadequate compensation offered by the power company for charge/discharge cycling of your batteries. They could offer more than fair compensation and it would still be a profitable thing for them to do (compared with idle generation capacity) but most people won't understand how cycling reduces the remaining life, and value, in their expensive battery.
For people who commute to work, they could plug in at work and just reserve 200% of the capacity they require after work before the evening charge. If they arrive home during high demand hours, they could continue to discharge into the grid down to a threshold and wait to recharge during lower demand hours. If the power company offers one free Starbucks latte per day in exchange, they will sign up at least 50% of EV owners for no additional compensation.

Powering the "house" with your car battery will decrease the life
of your battery. I hope the power company offers incentives to
to offset this. Not sure it makes sense otherwise.
