Miles Per Hour Of Charge?

[Pantera Dude]

Somewhere I thought I saw a chart with the miles per hour of charge time? Can someone direct me to it?

I am not sure what 19 hours at 120V means. The Tesla MS take 70-80 hrs at 120V, not 19 hours?????

The first row is 240V, 15A = 12A continuous. 240 * 12 = 2880W. 53 kWh / 2.88 kW = 18 hours. Close enough.

NEMA 5-15 is 120V, 12 amps continuous = 1440W. 53 kWh / 1.44 kW = 36 hours. There will be some efficiency loss due to battery temperature management, especially with such a slow charge rate... that's how they got 48 hours (which is conservative in my experience).

Fortunately the Roadster is more efficient than the Model S. It charges at a slightly faster 15 amps and it goes a little farther per KW due to its smaller size.

I don't have my logs with me but...

At 70/208 - I got 48 Ideal Miles per hour (McDonald's in Barstow)
At 40/240 - I get about 30 Ideal Miles per hour (at home)
At 12/120 - I get about 3+ Ideal Miles Per hour (at home)

Also, I've tracked Kwh from the grid versus what gets in the battery and I lose on average 25%. I read somewhere the Model S claims 93% effeciency rate but my Roadster is about 75%.

Thanks guys! I'm pretty sure what I saw showed 55 miles per hour of charge at 70 amps, 3 point something miles per hour of charge for 120V at 12 amps and everything in between? I don't think it was in a dream?
