Hello: Brand new Tesla S owner here. The most fun I have had since I brought my first car (67 GTO convertible) in 1968. I have a question about the charger. In my case, I am using the travel charger with a 6-50 adapter (there are superchargers within 4 miles if I choose to use them). I noticed that when the charger is plugged in but not in use, the lights are on and the charger is warm denoting some "vampire" power usage. I assume the wall charger acts the same. The question is, how much power is being used in the idle state, and why not have an internal shut off switch to completely cut off power use when not charging? Seems like a good idea as Tesla is all about overall energy savings. I don't want to keep plugging/unplugging the charger or flipping off the circuit breaker if the idle current is significant.
