    Mine is 96 kW. Haven't seen it ever go higher than that. I have seen users reporting 105 kW charging rate for the 70Ds so I would assume the 75 battery pack should be atleast in par with that (if not better).

    I've had an average voltage of 151 (peaking at 156) with an average amperage of between 132 & 142 (Petaluma & the Fremont Factory, respectively). But that's only 2 data-points, as my other 3 SuperCharger visits don't have stats (one time I went to the Fremont Factory at the end of a quarter, and the Wi-Fi there was so clogged that my logging service didn't get any data!)

    I have 60D and have gotten 295mph.
    Car was driven for 1.5 hrs on hwy before charge. I think low battery temp reduces max charge rate. Not sure about that. Got 85mph charge rate at same place when car was very cold (18 degrees F)

    96kW is the highest my HW2 75D has ever gotten, even with a hot car at 5% charge. From other threads by the battery nerds here, 96kW is the best our battery pack can handle (due to the math around the number of cells).

    I see the same. However, I have seen 70D battery getting a higher charge rate. So I am not sure if Tesla reduced the rate for the 75D for a longer battery life.

    Yesterday was my first SC experience. Charge rate started at 26.9, peaked at 121.6 and ended at 112.2 . 36 minutes for 61% to 90% which I thought was slow.

    My maximum have been 95 kW so far on SuC.
    There is a youtube video with Bjørn where he explains that even though the new 75 (and 60) packs charges at lower kW, they keep the same speed for longer. Taking more time before tapering off.

    So maybe it is a bit of different technology Tesla uses for these packs.

    Also, you will always get a faster charger in the lower end of the battery and if your car is cold it will also go a lot slower. I've been at a SuC here in Sweden where I only had 15 min of driving in a cold car and in the beginning it would only charge at 32 kW.

    I've read somewhere on the forums 96kW is max for a 60D/75D. Which was also confirmed by service.

    Ive never been higher than 96kW myself I SC about once or twice a week.

    From my trip from Seattle to San Diego and back I peaked at 95kw in my 17 75D. Thought about calling service to see what’s up, but now it seems like that’s the norm (I actually asked the service guys while charging at Buena Park SuC that is in their lot and they said that’s normal for 75kw battery). The good thing is every single supercharger along I5 charged at least 90kw at its peak.

    Yes, this is normal. Glad to hear that the Superchargers along your route were operating correctly. Sometimes they don't, and it requires shuffling around to find a better stall, or just some patience.

    Another thing I noticed is when arriving at a SuC with less than 5% SOC, it takes a bit longer to ramp up the charge. I once arrived with 3% in 33 degree outside temp and the charge fluctuated wildly between 0 and 15kw for a good 15 mins before ramping up.

    For the older battery that seems accurate. Some seem to have newer packs that can do more (pack is named 80p).

    Would you provide the video link?
    I'm in China and cannot browse or search youtube but can view if there is a link.

    I have seen over 100kWh at a SC with my 12/17 75D when arrived at 13% SOC. Have only SC a few times but viewed with eyes and data history from TeslaFi @ 295.24 A / 350 V.

    I once got 103 kW at a SC, when my car was a software locked 70D. That was over a year ago, not long after I got it (Early June '16) there was a software update that I'm pretty sure dropped the peak charging and I've never seen over 96 kW since. Not a big deal though, it still charges pretty fast.

    Max I’ve had is 118KW. Had this on multiple occasions. Am I missing something?

    For a short while, Tesla put in software limited 85 kWh batteries in some 75s. Sounds like you have one of those, so congrats on that and enjoy the faster Supercharging :)

    You can check the battery sticker if you’re curious to see if this is the case.

    Sure thing - have the 85kwh pack does that mean I’m only at around 87% at full charge? Can I be less precious around doing 100% charges?

    I should think so. I don't see how this would be different from the software limited 60 that was a 75 kWh battery pack. Still, if you don't need the range, I would probably only go to 90% in day to day and 100% for road trips.

    Edit: You should also be able to see it if you have tapering on your charge from 98-100%. If it takes 20-30 min or so, the battery is acctually at 100%. If it doesn't slow down (AC charge, not supercharger) it is not actually at 100%
