I question the OP's and his electrician's competence as electrical engineers and their knowledge of the J1772 standard.kubel wrote:I'm surprised people here are discouraging open mods. I think we should be saying "YES!" when people ask questions like this.
If one is a competent EE and has digested the J1772 standard, proposed modifications and their consequences, go right ahead.
I was a computer science major and barely know the basics re: circuits from college physics classes (for engineering and physics majors) and don't know the details of the J1772 standard at all. I also had to take some digital logic classes and worked w/breadboards, SSI and MSI chips w/gates, flip-flops, inverters and FPGAs, but that's all digital stuff.
I certainly wouldn't want to muck w/my stock EVSE using plans of questionable origin, even w/a competent electrician making the mods, unless that electrician also meets the above criteria.
Re: opening up the EVSE and modifying it, if the EVSE fails for whatever reason, after the modification, I'm quite confident that they'll tell you to take a hike and not repair it under warranty. After all, you've mucked with it and it's been modified from its original design.kubel wrote:You realize you are perpetuating a myth, right?cwerdna wrote:You realize that opening your EVSE voids its warranty, right?
They can only refuse to repair damages that you cause to the product, or that are caused as a result of the modification. Opening the EVSE alone will not void the warranty on the EVSE or the car. Using a modified EVSE does not void the warranty on the car either (unless of course it blows up and destroys something on your car, then they will refuse to repair THAT part).
If someone's crap modified EVSE design (not Ingineer's) causes damage to the OBC or some other part of the car via shortcuts like those of BareEVSE, who will go to bat for the Leaf owner/lessee in the event a warranty claim is denied?
