Hi all, so I picked up my Model S about 1 month ago. I had it in for some service last week and the guy at the service center told me just as I was leaving: "You don't want to supercharge your car all the time. It's really meant only for long trips. Supercharging all the time will degrade your battery" I suspect they logged all my trips to the supercharger (I only charge at the factory or using my chademo adaptor) and maybe they noticed how often I've fast charged. So here's my issue... before I knew that I went ahead and got 3-phase (480V) power at my home (at somewhat great expense) and the only reason I got the chademo adaptor was so I could use it with a chademo station at home. There is a good reason for this, I live up a mountain. It takes about 20% of the battery capacity to get from the bottom of the mountain to my home (3k ft elevation). On top of that, I have a 100 mile/day commute. Sometimes when I get home, I have to leave in only a few hours. I want to charge fast! I've read a few posts on the net, and the general consensus is that in a Nissan Leaf, fast charging *does* degrade the battery, but it doesn't seem like the Model S is affected. It makes sense to me coming from the RC world where you want to stay within LiPo battery "C" ratings. The larger pack should be able to safely charge at a higher rate. The Leaf is 24kWh, and the MS is 85kWh, this explains why the Supercharger can safely charge at the high rate. What do you guys think? Should I abandon my plans for chademo at home and just go with 10kW or 20kW (dual) home charging like everyone else? or will I be fine with a ~50kW chademo charger for home use?
