Now that I can charge at 240V (US) I have the option to do so at 100% or 50%, presumably about 4.5 hours on 50%. Are there any battery life improvements when using the lower charging level? My neighbor with a Tesla S says he was told by the dealer that their fast charge was useful when traveling, but there is a battery life hit for doing so.
I do wish I could change the Audi's charging level from the Etron App, and as a parameter in the car's charging timers, rather than only from the Bosch charging unit itself. In a perfect world I'd have the charging timer set to 50% on weekdays, and 100% on weekends. Given my utility's EV electric rate, I will only charge up overnight on weekdays, but I'd like to use the 100% charge to top-off on the weekends as we come and go, since the cheapest TOU electric rate applies all weekend. While I may well manually change the charger between 100 and 50% my wife will never do so.
