No doubt negotiating with site hosts is an interesting proposition, but of course the concerns of the host have to be balanced against the interests of the donors. One interesting issue is the mix of users that would be "competing" for the use of the EVSE. For example, there will likely be 10x the number of Leafs or Volts in the wild than say Model Ss. So if I understand correctly for "Universal" EVSEs the donors will be competing with the public who haven't even contributed for the cost of the EVSE. So a Model S donor who really needs the high capacity might find that they are in line behind Leafs or, worse yet Volts who have an alterate fuel, leisurely sipping electrons, and to add insult to injury these Leaf and Volt owners might not have even contributed to the installed EVSE. So a potential Model S donor might be forced to contribute to a more expensive "Universal" EVSE, but might find themselves more likely to be inconvenienced.
It would be interesting to see what the reaction of potential hosts would be if they were offerred a free Tesla HPWC plus installation costs versus no contribution at all, or a contribution limited to only $1,200 toward a "Universal" EVSE. I guess the negotiations will boil down to how badly you and your Model S donors want to install an EVSE at a particular location and how fast the roll-out of the Tesla Supercharger network proceeds.

Best solution would be 1 telsa HPC, and 2 lowcost 30A j1772
total cost 1200$ plus installation-cost
Mixing proprietary and "standard" chargers might have appeal to potential site hosts, but I don't understand your math.
A Tesla HPWC will cost at least $1,200 by itself. Two of ClipperCreeks residential 25 A J1772 chargers list for $795 each and their popular small commerical J1772 chargers start at $1,750 each. More sophisticated smart chargers cost a lot more than that.
Larry
Sorry, thought hearing the Tesla HPWC was around 500$
Cheap 30amp j1772 can be found at homedepot at around 400$ (edit : in britain 399£ this got me confused )
Electric Car Chargers - Alternative Energy Solutions - Electricalat The Home Depot
From your list the least expensive charger goes for $750, but its for indoor use. The least expensive 30 Amp charger suitable for outdoor use is currently on sale for $849 each.

maybe it's a premonition :wink:yes, my numbers are dreams not reality apparently :redface:
IMO you'll have a lot more success if you join with other EV drivers and work together... simply deploy large numbers of low cost Charging Stations that everyone can use... this will give you redundancy and increase the scope and appeal of the project to host locations significantly.If I were a donor, I'd vote for Tesla HPWC or a high power J1772 that is not free to use, with per-hour fee rather than per-kWh to further deter 3.3kW sipping cars from sitting there all day.
Well said, Larry

We will release a ruggedised J1772 version of our 32A Charging Station in the US for sub-$500 later in the year...

Any idea of the schedule for installation? And assume the HPC will provide 40amp (for those with single charger) using the UMC? Looking for help on my return trip from Tucson in early May.Sorry for the slow reply, I've been away from here for a bit. I looked at the Clipper Creek chargers, but since my particular destination was willing to install whatever I gave them, it made sense for me to get the HPC since it is almost half the cost of the clipper creek. Of course, I am lucky to be in the unique position to have someone who is just happy to get a charger of any sort. For a while at least, Teslas will be the only BEVs capable of driving these long distances anyhow.

Installation will happen within a month or so of me receiving the charger, which will probably happen sometime in February. I haven't used an HPC, but my understanding is that it doesn't require the UMC, it just plugs straight into the charge port. I would also assume that it would charge at 40A on a single charger equipped car, but I don't know for sure.
Anything new to report on the Chiraco Summit project?
Is 698 your Sequence number or your VIN?Still waiting on the HPWC, my updated estimate from Tesla is sometime in March at the moment. I'm getting jealous seeing all these HPWCs arrive at their homes!
Is 698 your Sequence number or your VIN?
rumor is that a supercharger will be installed at kingman and blythe!
Good to know...but didn't answer my question...Part of the reason for my delay is that I ordered my HPWC after receiving the car, so there is a bit of a cue ahead of me.
