Rated miles added in 30 minutes of charging at a Supercharger?

    We see a figure that you can add up to 170 miles in 30 minutes of charging at a Supercharger. Having charged several Tesla cars during the past 15 months, at no time did I ever see 170 miles added in 30 minutes. The figure was 110 miles added in 30 minutes under the best conditions. If you were able to add 170 RM in 30 minutes, what car were you driving and under what conditions did that occur?

    I don’t do rated miles, but have observed that the car charges at a rate close to 1% per minute. Perhaps faster from ~20% to ~80% when unpaired, and for sure slower from 80% to 100%.

    During the few times that it’s been necessary to charge from under 5% to 100%, it’s taken over 1.5 hours.

    Generally speaking during trips, arriving with 15% and charging to, say, 65% is not unusual and at a faster SC is done in less than 40 minutes.

    S90D, max range 294 miles - if you want to convert any of that to rated.

    Converting your figures to rated miles, you added 147 rated miles during that time.

    One can see the Supercharge times of Tesla batteries at Tesla Supercharging Time Calculator. Using that data, a S90D would add 147 rated miles when charging from 15% to 65% in 31 minutes.
    On my Model X P90D I generally add around 115 rated miles in 30 minutes of supercharging. Just wonder where the 170 miles in 30 minutes came from.

    I arrived at a SC with as low as 17%SoC left.
    I charged from 51 mi left to 70% (208mi rated range) in the first 30 min!
    That equals to 157 mi added in 30 min for our Model X 100 D with about 12,600 miles on the odd back then (Feb 10 2018)...

    For Model X 100D with 295 miles range, 170 miles represent 57% of SoC. I don't think anybody can supercharge that fast on existing 120kW superchargers because the fastest charge period is roughly between 5% to 48% SoC.

    However, if the figure is reduced to 2/3, that is, added 113 miles (SoC increase by 38%=113/295) in 20 minute, that will be quite achievable.

    This is one of my actual supercharge record showing that the SoC increased by 38% (from 8% to 46%) in 20 minutes (from 0:03.5 to 0:23.5)

    Great chart, I hadn't seen it before. Model X 75D is listed as a 70. Is this intentional for some reason?

    The X75D could be added to the first chart as we now know it gets 237 miles of rated range, not the guesstimated 10% less than a model S 70D.
