- Thanx a lot for this Bruce, it did help. :-)
Yes, normal over-night charging at home = not a problem at all, even here in Sweden @6 - 10Amps (230Vac) we just use normal wall-plug or engineheater-plugs at home, at work etc. No "stations". it is probably the long trips that Im most interested in now with high c-rate cells, so..how to communicate with the level3 DC station if I need fast Juice? Is it possible to set both the current and voltage levels when you start tho up a charge with them? We have for example 96Cell LiFePO4 in some cars, (also someting like 30-40 cells in some vehicles, but that seems to be unsupported in the future, as it seems to be only 200-600VDC & up to 400Amp in "level 3" DC ) (BTW, I think Volvo now have 20+ kW onboard AC chargers) /John ---------------------------------------- > Date: Tue, 3 Sep 2013 04:42:05 -0700 > From: [email protected] > To: [email protected] > Subject: Re: [EVDL] EVLN: SMUD installing Efacec's Dual-Standard > CHAdeMO+Combo L3 EVSE > > > [ref > http://electric-vehicle-discussion-list.413529.n4.nabble.com/EVLN-SMUD-installing-Efacec-s-Dual-Standard-CHAdeMO-Combo-L3-EVSE-tp4664949.html > ] > > > -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.).
