Well I spoke to an electrician today that lives near me and he gave me a deal to install a NEMA 14-50 outlet in my garage I could not pass up. Had some quotes as high as $700 and then $500. When he said he could do it for $300 I said sign me up. He'll be here next Friday to get er done with a 50amp fuse setup for a Clipper Creek HCS-50P which will charge at the 240v. 40amp and 9.6kw which should give me the ability to keep my ID.4 Pro S charged up easily and quickly. I don't drive a ton but do like to keep my charge topped up. I had a nice conversation with VW's Customer Service folks today. I told them I prefer to charge to 90% (never 100%). I also mentioned this to a friend who just happens to be a engineer for Toyota. The VW person said the cautionary recommendations of charging to 80% has almost everything to do with that they wanted to establish a "norm" that would allow for minimal degradation of the battery over time. She said this had to do almost entirely with those that are FAST charging at the 125kw rates. VW wanted to discourage those that use the fast charging often from slamming it with that voltage continually at that maximum rate even though VW has a buffer allocated to the battery system (77kwh vs. 82kwh). I can certainly understand why VW would want to establish a cap on those that would otherwise abuse the most efficient way to preserve the life of the battery. She assured me however that my in home charging at 9.6kw and 240v 40amp rates would not present any issues of longevity to the battery even occasional 100% charges. I prefer to err on the side of reason and stick with 90% which gives me the near maximum mileage without the wear and tear. The charger will be here Wednesday in time for me to look over the paperwork, but it's a near "no brainer" install to begin with and allows me to do all the fancy stuff the other chargers such as the WiFi one's and such do without paying for it. The car and Car-Net have all those features in them anyway. I can easily program my charges in the car's menu, and observe the start and stopping in CarNet. So I'm good to go. The government of course has their 30% tax break on the cost of all this so that's nice on my taxes next year.
