Hi Tesla fans,
I've convinced my wife that this is the year to trade in her gas guzzling ginormous SUV for a Model S. As part of my research I have a question I was hoping someone might be able to answer.
My current utility bill is based on two components; usage and peak demand. During the summer time (I'm in Phoenix) the peak cost jumps from ~$.05/kwh to almost $.09/kwh. More importantly the demand 'penalty' component to my utility plan takes my single highest on peak hour over the month and charges me $13.50 per kwh for that single hour.
So my question is this: Is the car capable of not charging itself, even if plugged in, based on time of day?
I realize I could just leave it unplugged during peak hours but beyond the inconvenience, no doubt mishaps will occur where we forget to charge it overnight, or we forget to unplug it and I watch the money fly out of my wallet to the electric company. Given the structure of the utility plan it would only take a single mistake during a month to send my bill sky high.
