How Many MPH Will Model 3 Charge From 110V?

[MorrisonHiker]

I see 12/12 A and 112v.

Hmm. With those numbers, I would expect you to see 4 or 5 mph. Did you wait to let it "ramp up" and check the average rate and how many miles were added after several hours as @ivan801 suggested?

I see 12/12 A and 112v.

That’s a significant voltage drop from 120V (note that what people are calling “110V” hasn’t been 110V for many decades now— it’s 120V.). Is there something else on that circuit? Is it a long run from the panel?

I just plugged at the office to a 10-15 outlet and I'm reading 4 miles per hour (1KW), 12/12A and 110V.

I will check again tonight from my home. It's a short run from the panel so I shouldn't have too much voltage drop despite being a very old home.

12 * 110 = 1.3 kW which is equivalent to 4+ mph

when you get home do the math yourself and divide by your average Wh/mi to calculate how fast you're charging.

With nothing on in the car, I get 5mph on the 5-15 120v connector. in my garage.

In the spring I plan a road trip across North Dakota. No Superchargers!. So the plan is to use Plugshare to find 240v locations where possible. Mostly, motels have 120v in the parking lot for ICE block heaters, but few have 240v. I plan to check into the Motel then go to a KOA or other RV park to get most of my charge, and walk back to the motel for the evening. When I have enough charge to get to my next destination. I will walk back and get the car. I will then park it at the motel and plug it into 120v for the rest of the night.

I do plan to get a 15-20 and hope to get 7mph with that. 7mph for a 16hr night is well over 100 miles.

I hope you post about your adventure. It will be interesting to see how things work out for you.

At home I can also charge at 12/12A - 114V = 4 miles per hour. I guess I must have the HVAC on yesterday....

I've read what ~ model S charges at, not sure if the new batteries would affect this. For 75 kwh battery plugged into standard 110 V outlet, would it be around 3 mph?

Yes - when I first got my M3 a few days before I had the 220 V installed, I used a 110V outlet and noted about 3 mph charge rate.

I’m getting 5 mph at 117V 12/12A in my garage.

I calculated from an overnight charge (109-110 volts/12A):

4.6 miles/hour
1112 watts/hour actual charge to 75 KW pack
84% efficiency
