And having it upgraded.

No it is far more involved than just putting a plug on it.davidh said:Are they just putting a new plug on it? Plug and throwing a switch? What modification needs to be made? Can I DIY it? The specs don't look that hard.

By the time you do it all yourself you will wish you had just sent it in.
There is an "open evse" thread (use the search) with details to make your own. You might be able to adapt that to the oem evse.
In addition to this...fooljoe said:http://evseupgrade.com/?main_page=faq_info&fcPath=4&faqs_id=24
There are quite a few changes that must be made to ensure the unit will safely operate on 240V. In addition, you would need to spend many hundreds of hours reverse-engineering the unit and developing new firmware from the ground-up to get anything other than a 12 amp pilot out of the unit. (We have, and it's not easy!)davidh said:Are they just putting a new plug on it? Plug and throwing a switch? What modification needs to be made? Can I DIY it? The specs don't look that hard.

Once upgraded, the EVSE is then capable of 4 times the power output, and there simply is no way to do this without writing lots of new software, no matter how many components you attempt to change.
There have been a few people that have spent the time to gut the 1st generation EVSE's (2011-2012) and install an open EVSE board inside, but this is a waste of money, when you can sell the intact unit for way more than an open EVSE will cost you to build from scratch. It would be even worse money-wise, and also extremely difficult to do this on a 2nd generation (2013) EVSE, as the PCB is potted into the bottom housing (difficult to gut) and the size of the housing doesn't leave much room to work with.
If you must DIY; Sell your unit, take the $ and build your own open EVSE. You'll have more fun, and save a lot of hassle and a wad of money!

Listen to Phil, a fair honest answer.
From the questions you've asked, you clearly have no where near the knowledge or background to safely modify the OEM 120V EVSE.
I kind of doubt whether going the open EVSE route is suitable, but you'll have to make that choice. I don't think it is for +95% of people.

TomT said:If such is the case, I would have hoped that you know there is much more to it than that... Alas, clearly you do not.
Regardless, your banal, insulting and arrogant response has likely insured that you will get no further response or help from anyone on this forum so good luck on your own.

You can't even get the quotes right in your post, and you think you can design and build an EVSE?davidh said:No reverse-engineering needed, all someone would have to do is open one of yours and copy(start there own business) or publish the changes. I doubt this patented.
So great a response. Especially love the last sentence. Have fun, davidh.planet4ever said:Good bye, davidh. As someone who claims EE knowledge but doesn't know the difference between firmware and a printed circuit while insulting someone who is an expert in both, you just landed on my foes list. May you put a new plug on your 120v EVSE and reap your just rewards.
