-First let's discuss 'levels' in the U.S. sae.org would like you to think it is the following: http://www.sae.org/smartgrid/chargingspeeds.pdf and wiki has their own views http://en.wikipedia.org/wiki/SAE_J1772 http://en.wikipedia.org/wiki/Charging_station but the realities of implementation translates to: Production plugins (EV and pih/phev) are designed to only draw 12A when charging on level-1 (L1, 120VAC * 12A = ) 1.44 kW Some public L1 EVSE have circuitry that limits/gets-goofy if more than 12A is being drawn (reports of conversion drivers having difficulty with columb ct2100 (L2 & L1) EVSE when plugged into its level-1 5-20 outlet, power shutting off, etc. Meaning a 20A outlet that only supplies 12A without issues). Home EVSE is powered from 240VAC, and is usually 3 to 6kW level-2. Public L2 EVSE's power source can range from 208 to 240VAC (depending on the electrical source, 3 phase/single phase, old-wiring, etc.). Public EVSE can supply 6kW (208VAC 32A off a 40A breaker. In the beginning, most automakers went cheap, and only offered a half-powered 3kW on-board charger in Production Plugins. Now some automakers offer an option to purchase a 6kW on-board charger capability. Recently ecotality/blink detuned/turned-down its public L2 EVSE power output: http://www.plugincars.com/blink-charging-stations-get-current-turned-down-128028.html Level-3 kW levels are a moving target. Because different manufacturers offer different kW capabilities. But what has been most implemented as public L3 is Blink's CHAdeMO https://www.blinknetwork.com/brochures/dc-fast-charger/index.html Blink DC Fast Charger SpecificationsMaximum Output Power 60 kW Max (Setting Adjustable 30kW - 60 kW) Maximum Output Current 200 Amps Minimum Output Current 5 Amps Output Voltage 200 VDC - 450 VDC Input Voltage 208/380/400/480/575 VAC 3-Phase Frequency 50/60 Hz Input Current 200 Amps at 208 VAC 89 Amps at 480 VAC 74 Amps at 575 VAC ... In the NW coast, a network of aerovironment 50kW L3 was installed https://insideevs.com/current-cost-of-50-kw-chademo-dc-quick-charger-around-16500/ from the Canadian board down to the California boarder through Washington state and Oregon as the 'Electric highway' consisting of both L3 and L2 EVSE http://www.westcoastgreenhighway.com/electrichighways.htm http://www.westcoastgreenhighway.com/WAelectrichighways.htm http://www.foxnews.com/leisure/2012/03/19/electric-highway-opens-in-oregon/ What type of L3 a host may want to purchase can vary too. Lower powered L3 EVSE are cheaper to purchase, wire-for, and draw less electricity (more efficient? or perhaps some drivers would leave early in frustration?) -While the above can seem confusing/a-bit-much to the non-techie-types, I will generalize and say: the majority of plugins on U.S. roads draw 3kW level-2 at home and off public 6kW L2 EVSE. And to a lesser degree use L3 at a 50kW level. {brucedp.150m.com} - On Tue, Sep 3, 2013, at 12:40 AM, Hoegberg . wrote: > Hi, > What is "average" ? 15 or ..60kWh ? > What is "level":s of kW in usa ? > John - -- View this message in context: http://electric-vehicle-discussion-list.413529.n4.nabble.com/EVLN-SMUD-installing-Efacec-s-Dual-Standard-CHAdeMO-Combo-L3-EVSE-tp4664949p4664981.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)
