Re: Nissan L1 EVSE third-party upgrade to both 120V and 240V

Core swap would definitely be the way to go -- order with $deposit, refunded after L1 received in good condition. No downtime.

The picture shows a great solution.. auto-switching, multiple adapters. This is awesome.

I can imagine many folks would get by with this alone, and no home L2 EVSE.

Re: Nissan L1 EVSE third-party upgrade to both 120V and 240V

got an email from Phil. thank you Phil for the very quick response quoted below
Hi Dave,

We aren't offering anything just yet, but considering offering an upgrade to your EVSE. You send us your EVSE, we upgrade it, include plug adaptors to allow 120V or 240V use, and send it back. We should be able to turn these around within a business day.

We are in Berkeley, CA.

No costs have been determined yet, we would need to source parts still. We had not planned on extending the length of any cables, though if you use a proper wire size, there is no technical reason why it can't be extended. Say if you needed an extra 50 feet, that could be done with #12 cable, and 2 L6-20 ends. However, Due to safety concerns, you generally don't want to run unprotected 240V cabling outdoors. Everything past the EVSE box is "safe" for use outside, but anything before it is not. One simple way you could make it safe is to have a 240V GFCI put in where you plug in the EVSE.

I suppose we could upgrade your cable length from the EVSE box to the J1772 connector, which would be safe to use outside. If you wanted to pay for the cable (not exactly cheap), we could likely do this for you, then it would be a safe way to have a long reach.

If we are able to offer this service I will be sure to let you know. It will involve sending us your EVSE and we will then send it back with the upgrade complete. We will warranty the upgrade for at least a year. It will then still work as before on 120V, but you then can also use it on 240V at your discretion. The unit will auto-configure for each voltage.

Also note that "110 volt" hasn't been available in this country since before WW2. The proper voltage is 120V. =)

I've also been in contact with Phil and he seems like a really nice guy. Long time EV enthusiast. We work a few blocks apart and I'll be visiting him in a few days to see what he's up to. It sounds like he really wants to make this upgrade accessible to EVers. I'll keep the forum posted,

Glenn

This is all fantastic news! Since the charger in the current Leaf is 3.3 kilowatt max and this modification will allow for 2.88 kilowatt charging with the included EVSE I personally don't see the need to get another EVSE just for the extra 420 watts.

It still boggles my mind why this functionality is not already built into the included EVSE.

Has anyone tested the unit on a leaf at 240v?

What is the charge time?

240v 16a

2800 watts?

Can't believe this wouldn't be an option from. Nissan

Course not many appliances run on 240v in the us

Definitely interested as well. This will make charging on the go a lot easier, and the Nissan 120V L1 EVSE is very compact.

Combine this with a quick220 adapter and a couple heavy duty extension cords and you can charge at 75% normal L2 charge rate just about anywhere.

Bonus points if Phil can build a quick220 type adapter for less than what they charge ($160 for a 15A quick220)...

My math comes up with about 87% of "normal" L2 :)

Has anyone tried to purchase an extra L1 EVSE from Nissan? I'd be interested in purchasing an extra if Nissan has them available. It will be my only means of charging so I want a backup.
