15% Charge Loss

[Jon Chow]

I charged my new Model 3 using a 110v outlet for 15 hours last night from midnight to 3pm (which qualified for the lowest rate of $0.27/kwh) and got 80 miles or 18 kwh in the car. Can I expect this 5 miles per hour charge rate when the weather gets colder?

I noticed that the electricity used for just charging the car was about 21kwh--3kwh more than the car received? Would I experience similar percentage loss using a 220v outlet?

Sorry, I don't have a good answer for you, but is $.27/kwh a typo? I'm in Phoenix and pay $.08/kwh off peak. If it's accurate, HOLY CRAP!

I pay $0.36/kwh average. SDGE are legit criminal.

There is no you will experience less loss at 240v. At the same time there is some question, IMHO, as to if there is a sweet spot or not vis a vis current. This doubtless gated by each persons unique circuit and environment. But the voltage increase, in this case, should not carry a heat (loss) component.

i’m testing various charging amperage’s now, so we’ll see in the course of time
