I verified the default 8A and the optional 12A on my Mercedes B EV Lear L1 EVSE. It was spot on. OpenEVSE's are correct in current but the frequency is 998 HZ instead of 1000HZ. It falls within tolerance though.
I use a clamp on Fluke ammeter which I figure is pretty much spot on. All my adjustable EVSEs draw an actual 1a less than they say so maybe it's my vehicle? In the case of the Zencar EVSE for example it shows it's set for 20a but the actual draw is a tad under 19a, same thing with my EVSEupgrade EVSE, when it blinks 20 times(meaning it's set for 20a) the actual draw is more like 19a. Again I think it's more of a safety thing than anything else, you wouldn't want it the other way around, that is drawing more than set for.
Webeleafowners, no you can go up to at least 27.5a @ 120v with a 6.6kw Leaf charger, 12a is the max for the 3.6kw charger and my Juicebox has no problem outputting the full 27.5a @ 120v on my '13 Leaf with the 6.6kw charger package.
Hmmm. I'll have to check it out again. We have a Nema 14-50 240 volt circuit in the garage at home so no problem getting the full 27 amp on the Leaf at home. But when we are on the road with the motorhome with the smart ED (which has a 3.3 KW charger) we only have access to a TT30 plug on our property down south. I can not get it to go over 12 amps when it is on this circuit and when I asked Juicebox about this they said it couldn't be done because of the J1772 format. Maybe I misunderstood but either way I can not get the Juice box above that on a 120 volt 30 amp circuit. When it is on the 240 volt circuit it charges at the 33 KW rate. Any thoughts. Thanks in advance.
Yes I assume the Smart ED's 3.3kw charger is like Nissans in that it stops at 12a @ 120v, but again with the 6.6kw Leaf charger it can go to 27.5a on either 120v or 240v, assuming your EVSE can output that high on 120v . I just checked and even the current Juicebox's can, from emotorwerks site about the Juicebox:
" 100-250 VAC, single phase" note on my Juicebox it has separate memories for 120 and 240v, that is you can have L2(240v) set for 20a and L1(120v) set for 27a, which I find handy. My Zencar EVSE doesn't have separate memories so whenever you change one voltage it changes the other.
I think you'll find lots of mis
information about whether a particular L2 EVSE also works on L1, it's my belief it's more of a CYA thing, since L2 EVSEs often times go to 20 or even 30a they don't want JSP plugging his 20 or 30a L2 EVSE into a standard 15 or 20a receptacle. It's like they don't seem to even know of the existence of 30a 120v outlets(TT-30 being a prime example and at most campgrounds). Of course 240v is better(twice as fast) but 24a @ 120v is still twice as fast as a OEM Leaf EVSE and equal to 12a @ 240v.
