In the light of Jerome's recent remarks about feature requests coming from owners that actually set Tesla's development priorities, I humbly submitted this feature request and I hope all of you with TOU rates do the same. I would like to be able to prevent the Model S from using shore power during they day for chargers on TOU rates: At my house, I have a dedicated EV meter with time of use rates. Which means I almost never want to pay the highest day rate. I pay 3x during the day and the costs for just the little bit of usage during the day means that my electric bill is 30% peak day usage and 70% night super off peak usage in terms of actual cost even though the energy usage is vastly different. I would like to be able to select the charger at my house and choose to have it almost never be used during the day. In other words, when I choose to turn on the climate controls, it doesn't use "shore power." Similarly, when I plug in at the end of the day, it starts using "shore power" sometimes to check the charger and/or power the climate controls. I want it to not do that. On the other hand, if I manually start charging, then it is free to use shore power during the day. Also, I can't use smart preconditioning as a result since it uses shore power at 3x the rate.
