Interesting question. Ofcourse, in 3 years we should be able to buy a replacement EVSE and give that back ...

I'm tentatively interested, as long as it's not too expensive. I guess $200 might be the "Well, I'll have to think about it" threshold for me.

I'm on the list for a potential free eTec charger*. If I luck into one those, my interest in this mod will diminish a bit. It won't diminish completely, however, since it sounds like this would make for a very nice universal travel-charger*.

I'd encourage Phil to try to work out some sort of "core charge" arrangement, since that would shorten the turnaround, and let Phil (and the ants) do the work at a more leisurely pace. I don't want him to be hurrying.

* I mean EVSE, of course. 8-)

I can assure you nothing is rushed and if there is enough demand a core program will be in place. You are in the ballpark in pricing that would include return shipping likely. Parts costs add up quickly not to mention time to do it properly. By mid the end of next week there should be some feedback for everyone.

Was the de-potting just to discover the nature of the circuitry? Now that they know, is it necessary to de-pot the thing to do the mod? If so, yeah, that would be labor intensive. I'm hoping that they won't need to, or maybe only selected component...

- AeroVironment's L2 EVSE unit: 240v x 16a = 3840 watts
AV's EVSE is rated for 240v @ 30a, or 7200 watts.

Omkar, if I have my LEAF by the time you decide to have this done to your L1 EVSE, you can borrow mine til yours is done. If you want to do it before I get my LEAF, I bet someone else here in OC will lend you theirs. :)

1. The 2011 LEAF's max charging current draw appears to be just shy of 16 amps. Thus about 3800 watts (not just 3300 watts) when using 240v source.

2. A local loaner L1 EVSE is a good idea to cover the 6 to 14 days (2 to 5 days Ground shipping each way) that your EVSE would be gone, while "getting fixed".

3. Is the non-spec. "item/feature" that was discovered in the L1 EVSE something that we should know about (for safety) in normal, unmodified, 120v operation?

Much appreciated Phil!

I am sure that there would be plenty that would trade your undated unit for a stock unit

This is all very interesting. There have been many comments on new EVSEs to check if they are UL compliant... will the conversion meet UL specs?

I think I still want a permanent cord up on the wall of the garage so I will probably pass on the conversion.
