We currently own a model 3 performance (built July 2019) and a brand new model S performance to be delivered early December 2019.
I am on a time of use rate plan with my cheapest rates only from 12am to 6am daily.
That leaves us with only 6 hours to charge 2 Teslas overnight.
We have installed 2 separate dedicated 50amp circuits (one for each car) both with a NEMA 14-50 plug.
When I look at the model 3 charging screen, it shows a max of 32amps when plugged into a 50 amp circuit.
Does the model S also max out at 32 amps when using the included mobile charging connector?
So if both Tesla’s were charging simultaneously, it would be 32a + 32a = 64a total coming off my main circuit, correct?
Am I missing anything here?
I’ve run some rough numbers based on our individual commutes, and 32 Amp charging. Our new model S will need approx 4 hours to recharge each night and my model 3 will only need 2 hours because my commute is only 1/2 as long.
Should I schedule charging so the model S charges from 12am to 4am and the model 3 charges from 4am to 6am?
Or should I just set the model 3 charge speed down to 16amps and let both cars start charging simultaneously at 12am?
Which choice would generate the lowest peak load on my electrical panel?
My goal is to put the lightest load (wear & tear) possible on my electrical panel, while still getting our charging done within the 6 hour “super off peak” window for my electric bill.
32amps charge speed is more than enough to cover the daily use of both our cars. I don’t need to charge them any faster.
I don’t want to have to go out and purchase the Tesla wall connector(s) at $500+ each. I would much rather just use the included connectors that come with each car.
