I don't know of any company that offeres free electrons per month, etc. Right now each network is trying to grow as fast as possible (most of them expecting to be bought up at a good markup from their current stock prices). Eventually there will be one or two national systems in the US with pretty similar payment methods (credit card) and the price will vary with location and possibly time of day or maybe regional networks some dozen or so.

As more EVs are on the roads there will be more pressure for user convenience. The first company who accepts credit cards without a subscription will have an advantage gathering the opportunistic chargees. The only reason this won't happen is if there is a significant advantage in operation by having "subscribers" rather than customers. Costs are highly dependent on peaks and demand. So there may be a way to moderate that through subscriptions that isn't applicable to allowing roaming users. At this time I don't see that happening since peak costs can be mitigated by passing on those costs to the user. If there is useful feedback provided users will develop charging habits that minimize their costs and system costs. I've seen charging stations on the web that have solar panels built in along with batteries as self contained units requiring no outside electrical connection. Plop it in a parking lot and it makes money. I can see that happening in work parking lots. When your car is about fully charged you can walk out to move it and another can take it's place. That might work much better with subscribers. You get a bit of exercise as well. -- Rick C. +++ Get 1,000 miles of free Supercharging +++ Tesla referral code - https://ts.la/richard11209

When done with one car, it moves itself back to the base stations to recharge, then move to the next car in the queue. It would be a lot cheaper than having fixed charging stand in every space and no need to remind drivers to MOVE YOUR CAR when done.

I am entitled to good and bad ideas once in a while.Actually, my original thinking is flying drones. The chargee attach to a stationary buffer battery. The drones shuttle electrons back and forth from the base station. The transfer voltage can be in the 10,000 volts, 10 feet up in the air, without human intervention.

I don't know of any company that offeres free electrons per month, etc. Right now each network is trying to grow as fast as possible (most of them expecting to be bought up at a good markup from their current stock prices). Eventually there will be one or two national systems in the US with pretty similar payment methods (credit card) and the price will vary with location and possibly time of day or maybe regional networks some dozen or so.

Most of the current networks will be bought up by the larger ones. As more EVs are on the roads there will be more pressure for user convenience. The first company who accepts credit cards without a subscription will have an advantage gathering the opportunistic chargees. > > > > > > > > The only reason this won't happen is if there is a significant advantage in operation by having "subscribers" rather than customers. Costs are highly dependent on peaks and demand. So there may be a way to moderate that through subscriptions that isn't applicable to allowing roaming users. At this time I don't see that happening since peak costs can be mitigated by passing on those costs to the user. If there is useful feedback provided users will develop charging habits that minimize their costs and system costs. > > > > > > > > I've seen charging stations on the web that have solar panels built in along with batteries as self contained units requiring no outside electrical connection. Plop it in a parking lot and it makes money. I can see that happening in work parking lots. When your car is about fully charged you can walk out to move it and another can take it's place. That might work much better with subscribers. You get a bit of exercise as well. > > > Another option is a self-driving charger. User just sign up in a waiting queue. When done with one car, it moves itself back to the base stations to recharge, then move to the next car in the queue. It would be a lot cheaper than having fixed charging stand in every space and no need to remind drivers to MOVE YOUR CAR when done. > > great idea, just need to have an onboard generator run it on diesel or better yet coal or firewood to make it perfect.. > > > > would make Rube Goldberg proud > How about Nuclear? But no need to have it mobile, running in base station is good enough.Alternatively, solar during the day and hydro at night and bio-diesel backup. The site i am thinking about is next to a body of water and plenty of land for solar. Just pump water up the hill with the sun and hydro-electric when the sun is resting.
