IMO: public L3 located every ~50 miles is important. Please sign to support this. ] Peri, Your last statement that says you have used public L3, answers your last question. You live in an area that already has an established public L3 & L2 network along two major highways. Consider us other poor slobs that don't. First, lets show what is out there. See http://www.afdc.energy.gov/locator/stations/results?utf8=%E2%9C%93&location=98642&filtered=true&fuel=ELEC&owner=all&payment=all&ev_dc_fast=true&radius=true&radius_miles=200 Shows public L3 from the Canadian border down to California where public L3 EVSE stops, until along I-5 you reach Sacramento. Then see http://www.afdc.energy.gov/locator/stations/results?utf8=%E2%9C%93&location=94002&filtered=true&fuel=ELEC&owner=all&payment=all&ev_dc_fast=true&radius=true&radius_miles=200 Shows public L3 from Sacramento over to the San Francisco Bay area. Then no public L3 until you reach Los Angeles, CA. See http://www.afdc.energy.gov/locator/stations/results?utf8=%E2%9C%93&location=+90021&filtered=true&fuel=ELEC&owner=all&payment=all&ev_dc_fast=true&radius=true&radius_miles=200 Shows public L3 from Los Angeles to the Mexican border. It quite an oddity to have all the best planned and laid out public L3 & L2 up in WA and OR, when the highest population of Production EV drivers are down in CA. Also notice that in the SF Bay area the L3 are clustered too closely, and installed with no contiguous planned-use in mind (higgledy-piggledy, each Hi-Tech company dropping a boat-load of ca$h so they have the bragging-rights to encourage the best talent to come and stay with them). Having a National effort to plan and lay out public L3 and L2 as well as you have it up in WA and OR is what this petition is mainly for: - Production EV drivers could get from point A to B and back easily - no wasted time, effort, and money on dis-contiguous Fed-funded installations Tesla is doing there own thing and are IMO not part of this initiative. Though it is possible Tesla could be invited to put their superchargers at a public L3 site. As I see it, this petition would public interest, and Fed efforts would be mainly focused on the ~$20+k Production EVs which use CHAdeMO (Leaf, iMiev, +) or Combo (GM, BMW, +). Those Production EVs' measured range vary. The shortest range being the lowest common denominator (the iMiev). A ~50 mile distance between public L3 sites would be prudent. WA state, and OR 's public L3 is a shining example for others to draw from. The Dutch are working on establishing what you already have in WA and OR http://electric-vehicle-discussion-list.413529.n4.nabble.com/EVLN-Cannabis-Sex-Cheese-amp-soon-EVSE-every-31-miles-in-Holland-td4664162.html This petition could see the same great L3 & L2 EVSE network established across the U.S. connecting East to West and Canada to Mexico. The BC2BC EVent http://electric-vehicle-discussion-list.413529.n4.nabble.com/EVent-BC2BC-2013-Canada2Mexico-EV-Rally-Sat-6-29-10a-Blaine-WA-td4663909.html#a4664078 showed the weaknesses of having a lack of a public L3 infrastructure as soon as they left WA and OR and crossed the CA border. Once a public L3 & L2 EVSE network is established along major highways, I do not envisioned an individual driver using L3 on a regular basis (if you are going to drive that much get a Tesla-S EV or high highway-mpge ice). Mostly, I envisioned them using L2 (3 or 6kW) or L1 at home or work. But when push comes to shove to get a somewhere, or they decide to take that rare weekend trip, having an established public infrastructure will pay off. With the numbers of Production EV drivers growing, the amount of those more rare uses of L3 would make those public stations well-enough to justify their installation cost. As I have posted before, while what AeroVironment installed (one L3 and one L2 at a site) is a good beginning, later as use grows, it would be wise to install three L2 for every one L3, and the L3 should the dual coupler type that has both a CHAdeMO coupler and a Combo coupler (probably each L3 would only charge on EV at a time like what Blink does with their CHAdeMO L3 EVSE). The L2 would be for those wanting that rare charge from 80 to 100%SOC, and those in a waiting queue to use the L3 EVSE. Please support letting us other poor slobs have it as good as WA and OR by signing the petition (URL at the top). {brucedp.150m.com} ... http://www.merriam-webster.com/dictionary/higgledy-piggledy ... http://www.collinsdictionary.com/dictionary/english/when-push-comes-to-shove - On Sun, Aug 11, 2013, at 07:00 AM, Peri Hartman wrote: > ... what is the purpose of having fast charging every 50 miles? > ... if you plan to travel several hundred miles, plan on > stopping every 45-60 minutes and spend another 20-30 charging ... > > So that leaves people making 50-100 mile trips.

That works pretty well.) - -- http://www.fastmail.fm - The professional email service _______________________________________________ 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)
