: Leviton Evr-Green 160 oddity

The last time I checked Leviton for documentation on their Evr-Green 160 EVSE (which has an option of using a NEMA 6-20P wall plug-in, instead of being hard wired) the user's manual didn't work (downloaded a different document). It works now to download the user's guide (http://www.leviton.com/OA_HTML/ibcGetAttachment.jsp?cItemId=yqKzkUx-sAsAQu7D9A.9.Q&label=IBE&appName=IBE&minisite=10091).

The question? In specs it says 16 amps 240VAC (and 3.8kW, so slightly stronger than the Voltec - I wonder if the Volt will draw 3.8kW so it could feed a full 3.3kW into the battery with power left over for the TMS, but I digress, and let's avoid digressing further by not wondering about 220VAC and 208VAC).

BUT.... The title of the user's guide is:


Level 2 - 160 Home Charging Station
Cat. Nos. EVB22, EVB26 - 16A @ 120/240VAC, 60Hz
User Guide


OK, granted that answers the 208/220VAC question... Does this mean with a NEMA 5-20 to 6-20P adapter could this unit be plugged into 120VAC in a pinch?

Rusty,
Do you know how much this unit costs? I am looking into charging stations for work and am trying to figure out the cheapest Level 2 solution. And would this one work only in the home setting, or could it be mounted on a brick wall or pedestal?

Plug In America (http://www.pluginamerica.org/accessory-tracker) doesn't list a price for it (commonly, as many EVSEs aren't available yet). It does say Leviton is expecting Q1 '11 availability (which would be around now). Given that it's mounted through a back plate, I presume you could use masonry screws or bolts through a pedestal to mount it.

From what I've seen, the SPX Voltec EVSE (https://www.homecharging.spx.com/volt/pdf/SS10-283_VOLTECH.pdf) is the lowest cost unit available. Those who have one, what would it be like to brick or pedestal mount?

Q1: I don't believe the Volt can draw more than 3.3kW through the on-board power converter. The next time I am plugged into a ChargePoint EVSE which is capable of delivering 7.2kW, I will try turning the climate control on at 100% while it is charging. The ChargePoint has a meter so I can see if the Volt will draw more than 3.3kW.

Q2: I don't think it will work at Level 1 (120VAC). The installation instructions say to wire it hot-hot (240) and ground. There is no provision for connecting it to 120VAC.
I think they are just using 120/240VAC as a standard nomenclature for single phase residential service.
Even it the Leviton did work at 120VAC it would not charge any faster than the Level 1 charger that comes with the car.

Agreed. If the plug were converted to a 120VAC service through an adapter, one leg would be neutral. I'm just curious if this EVSE tolerates that sort of thing.

I was plugged into a ChargePoint EVSE this afternoon. Here is the result of my experiments. The highest consumption I saw was a little over 3.3kW (less than 3.4kW). I tried just charging with the car off and charging with everything on and the climate control turned up as high as it would go. The meter on the ChargePoint read between 3.29 and 3.37 kW the whole time.
So, as I suspected, the 240VAC converter in the Volt will not use more than 3.3kW regardless of load. Any load you turn on while charging is reducing the current to the battery.

That's a ridiculously simple and marvelously useful experiment. Thank you adamsocb!

I installed my Voltec EVSE myself to a stucco wall. It would be easy to install to masonry or a wood post, with the right fasteners. With the post, the challenge is getting the wiring to the location (maybe underground conduit?).

as an update I called Leviton today and they say they are now looking to launch in June with pricing announced then. They asked for my details so that they could contact me when they have the specifics. This is a Plug in 240 charger that will apparently be sold in Home depot amongst other places and online. some interesting notes:

The EVB26 model is for hard-wire installations, EVB22 is a plug-in model.

Excessive Cable Strain Detection - On detection of excessive pressure
on Charge Connector cable the EVSE issues a warning and de-energizes
the cable.

Thank you for the follow-up. This is good information.
