While getting estimates for adapting our household electrical panel to handle additional breakers and considering the cost differences between the HPWC and NEMA 14-50 or 30 outlets we have been successfully charging using only the 110V 15A outlet in the garage.
Our house has the breaker box on the side opposite the garage, about 100 feet away. The estimates we have gotten include the Tesla site survey design. The gentleman doing the actual survey was knowledgeable and thorough. The designs coming back from Palo Alto, CA are unnecessarily expensive.
A local electrical contractor has been much more specific about the costs of components affecting the overall price of each option. The HPWC would need a much larger gauge wire, where a NEMA wall outlet requires smaller wires, due to the smaller current.
Bottom line: for the past month we have been using the MS85 every day for all our normal errands and commute. For trips beyond 30 miles away we stop by to grab a 20 minute charge since the SuCs surrounding Pittsburgh, PA are on the way and never crowded.
From research here on TMC data shows that a 240V, 25A charge rate is the most efficient. When finding that data it opened up the door to considering the NEMA 30A outlet, which will charge at a max continuous rate of 24A (80% rated capacity). I am usually one to overbuild things to prevent overheating and provide for expansion in the future. Since we're not certain of how much longer we will be in our current house, spending thousands on electrical upgrades isn't making sense. Realtors we've consulted have said that sadly electric car friendly or adding solar are not reasons our house will increase in value where we live North of Pittsburgh. In fact, we were told our house could be harder to sell with these modifications.
Any one else using only the UMC to charge from a 15A outlet only? I get about 3 mi per hour rate of charge on 110V-15A. The car is plugged in between 14 and 16 hours a night. We do not have tiered rates for electricity unfortunately. 42 miles is enough for the daily commute and a little driving around town.
I find that I'm only taking the UMC with me on longer trips when I travel in the MS every other month or so. Most days it remains in the garage, coiled up and ready for the car to arrive and be plugged back in.
