I did not find this discussed, please direct me to threads if it's already done. I have the option of how to pay for my residential electricity, one option is based on Peak Demand (just like our office commercial supply). With electric kitchen and dryer, demand is already reasonably high - add a MS and not manage them and this might be a bad idea. However, if I could manage the car, to ensure it was smart enough not to try to charge when demand was already X, or was only allowed to charge at a rate which would make a total demand of Y - it might work well. There are various tools which would allow me to measure demand and consumption, question is - can MS be externally driven to either stop charging until it gets another signal or even better drop it's demand to a specific level?
