Yes, a business model with a reasonable return in investment is necessary. It seems most people think a proper system should be a chain of ESVEs along the major highways, enough so you can travel long distances. But does this make sense?
Ultimately, yes. When range matches a tesla or better, i think people would expect to use their ev for 400 mile trips. But if your range is 75 miles, are you truely willing to spend 20 minutes charging for roughly 1 hr of travel? Not me, except for making a point. Instead, a network of ESVEs needs to be based on how people use theorem vehicles. For your ICE (oh, you don't have one?), when do you decide to stop for gas? When you have 1/4 tank left? You know, under normal conditions, you'll find a pump easily within the amount of range left. Now, translate that to EVs. Ideally, you should not need to think about where to charge till you have about 1/4 of your charge left. If along highways, that would mean about an ESVE about every 15 miles. I don't think there would be enough users to support a business model based on this. Of course, as we get more tesla-like range that gap can't grow. I'm going to postulate that a good business model is not based on stringing ESVEs along the highway but instead making sure one is availabe within 5 miles or so along most urban and suburban routes. For now, that's where people use their EVs. With this, you could leave your house or apartment (even with no home ESVE), and be confident of your range. Enough customers: possible viable business model.

EVSE companies just manufacture and sell EVSEs, so why would one expect they determine where EVSEs are installed? I think there needs to be a way for people (besides manufacturers) to make money from EVSEs in order for them to proliferate. Public funding can get it started and demonstrate feasibility, but we can't afford to allot public funding at the level required to build out the entire infrastructure. There has to be a working business model developed. I think we EV drivers should expect to pay an amount for using an EVSE that supplies the owner with a reasonable rate of return. The question of course is always what is "reasonable". The EVSE pays for its capital and installation cost in 5 years, 8 years...? Local government can help by facilitating installation near business owners who are willing to purchase and install EVSEs. And of course there need to be enough EVs on the road in that locale for the owner to recoup her/his investment in an acceptable (to them) period of time. Currently, where I live the owner would starve. :^)) I would pay to install some if I could get even 2% annual ROI. Gas stations started out as "service" stations, usually coupled with mechanics service, permitting them to generate much more revenue than by just selling gas. This model doesn't seem applicable to EVSEs. -- View this message in context: http://electric-vehicle-discussion-list.413529.n4.nabble.com/Re-EVSE-overcrowing-replaces-range-angst-tp4661763p4661777.html Sent from the Electric Vehicle Discussion List mailing list archive at Nabble.com. _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA) -------------- next part -------------- An HTML attachment was scrubbed...
