Hi all,
Since I got my car (Model 3 Long-Range Dual Motor (not Performance)) I've been curious about the math behind the stated range & consumption.
Tesla says the (long range) battery capacity is 75 kWh.
They say the range on a full charge is 310 miles.
If you do that math, 75,000 / 310 = 242 Wh/mi.
So I've always looked at the consumption figure on the screen and thought if my consumption figure was higher than 242 Wh/mi I was getting worse than stated mileage, if the figure was lower I was getting better than stated mileage.
Then this afternoon I looked again at the new-car sticker that came with my car, and the EPA figures on it.
It says a range of 310 miles (cool) and fuel economy of "29 kW-hr per 100 miles," or 290 Wh/mi.
Well, if the range is 310 miles at an economy of 290 Wh/mi, then the battery capacity would be 310 * 290 =
89,900 Wh... or 90 kWh, not 75 kWh.
If the battery is 75 kWh and the economy is 290 Wh/mi then the range is only 259 miles.
So something is not right there.
Anybody have any ideas?
