Long Range Battery - $9,000
- Range: 310 miles
- Supercharging rate: 170 miles of range per 30 minutes
- Home charging rate: 37 miles of range per hour (240V outlet, 40A)

Ok, calculation time:
- Supercharging rate: 170 miles of range per 30 minutes: 170miles/30minutes = 340mph (avg rate during a typical 30 minute interval) (as a rate; not actually 340 miles in an hour)
- Home charging rate: 37 miles of range per hour (240V outlet, 40A): 240V*40A=9,600W = 9.6kW; (340mph/37mph)*9.6kW = 88.2kW
So,
roughly speaking, the
Long Range Battery SuperCharges at an advertised
average of ~88kW, for half an hour, to get 170 miles of (average rated) range. That could mean that it ramps at different rates during that 30 minutes, so that "88kW" doesn't mean it's any type of maximum; it could be well over 88kW as a max. I think the max rate is above 88kW, in my uninformed rough opinion.
The idea, though, is that you pull up to a SuperCharger during a long distance trip, and it gets approximately 170 miles in half an hour, give or take variances due to conditions. That means get out, plug in the car, stretch, get your stuff, take a walk, do stuff, come back, and it should have about 170 miles in it, enough to go to the next hop. If you want a longer hop, wait a bit longer.
It seems very reasonable to me. Remember: I came from a 75D Model S with software limitation to 60D. That means that I could charge up in my Model S at 99kW, but the ramp left me in sub-99kW for a great deal of a SuperCharge session. It meant I could stop at a SuperCharger with good amenities and basically come back to a full enough car to zip off to the next stop, and that at SuperChargers with bad amenities, I was stuck waiting there for the SuperCharge to get to a good level; often, I'd read a book, or use the computer, and the time would fly away. The biggest problem was how much time it added to trips; it could eat up a day if I'm not careful and I while away too much time at stops. That's why I prefer stops with good amenities; I don't get engrossed in a side task while sitting in my car. Sitting in the car is bad for exercise and all sorts of other things; I'd often leave SuperChargers with bad amenities wanting to pull over and stretch my legs.
What about the standard range battery Supercharging speed?
One thing stayed kind of constant in most Model S and Model X's: if all of the various battery sizes pulled up all depleted to a SuperCharger and plugged in at the same time, they would all get to around 80% state of charge at about the same time, on average (but due to specific conditions it would vary greatly). The only big difference, of course, is that 80% meant more range on some vehicles than others.
