Has anyone noticed supercharging changes with 2020.48.37?

    I've got a pre-facelift 90D; over the past couple months or longer, I rarely see over 100kw charge rates, or if I do I see them for a few moments at the start of the session.

    I updated to 2020.48.37 over the weekend and on my way home (after a "full to 30%" highway drive) and got this:

    It stayed at this rate (or at least well above 100) for a good long time too.

    Others have reported that the 2020.48 firmwares have increased supercharging speeds.

    well, when I went to supercharge at a 250kW charger, all I got was 68kW....I now have 2021.4.3...Next time I need to supercharge, I will up to 90% from around 30%....we'll see what happens

    I posted this in the throttling thread but thought putting it here also was appropriate:

    I finally received the 2020.48.37 update in my 2016 S-75 and supercharged for the first time this morning starting with a warm battery and 18% left. Before throttling, the peak charge was in the 97kW range, and after throttling, it would very briefly touch 82kW just below 50%. Today the car reached a peak charge rate of 108kW, so that’s quite a bit higher than when it was new. It tapered to the former max of 82kW at just before 50% and seemed to taper from there at the same rate as it had before the update. This is a significant improvement that will make long distance traveling much easier especially as more superchargers come online and the “splash and dash” method in the low end of the range can be used. As a heavy supercharger user, I’m very excited with this update.

    This doesn't apply to the 85 kWh packs, right?

    Not sure about everyone but I have a Jan 2020 Model S and have notice a very sharp throttling in the last three revisions....I am currently on 2021.4.3 and will charge later this week....I think the key to charging maybe making sure you have a warn battery....I tell my wife who gets less than 100% efficiency while charging at home to use the conditioning mode and warm the battery prior to charging.....since doing that, she get 100% efficiency while charging at home at 40a, 9kW and 240v.....And when she does this, her range is improved and battery capacity goes up a couple of percent...She has a Jun 2019 Model 3 AWD LR.....she has never seen more than 301 miles range and is at 285 now....have not been able to figure out what is happening....she has 10,230 miles...

    I'm definitely noticing some algorithm changes, unfortunately for the worse.

    My high mileage (115k) S75 is peaking around 110kw near 20% SoC but tapering very aggressively, like under ~40kw near 70%. About 70kw at 50%.

    That's a bummer. Also quite a bit off the prior peak speeds I was seeing last summer where I'd briefly get ~140kw near 20%. Guess they decided that's no bueno.

    I don't supercharge that much, I'd guess less than 10% of my miles are DCFC.

    Same. 17’ S75D, was hit with the throttle permanerf before the 350V packs were sped up a bit. Been stuck at 82kW for the the last two years.

    Very pleased to see peak charge rates exceeding 100kW.

    2020.48.37.1

    Yes, got it last week.
    But I have not supercharged so no idea if anything has changed.

    I have the 37.1 software on my 2013 S85, just completed a roadtrip from CO to FL.

    My charge experience may not be applicable to most cars of this vintage as my HV pack was replaced with a new 350v remanufactured pack that I have now put 2k miles on, this trip I saw over 100kw charge rate all the way up to just over 50% charge then tapered from there.

    Trip started about 24%, drove until 9%. 30°F. Regen limit resolved but power limit decreased only slightly so battery was still cold. Targeted nearby Supercharger after errand but battery did not preheat. (Why not?)
    Started charging at 7% 64kW but slowly rose to 109kW by 27%. At about 40% power started to drop and fans became loud.
    This car started with 132kW when new but until today I’d not seen higher than 92kW for some time.
    At 50% after 20 minutes the power was still 91kW. This is an improvement in front loaded supercharging compared to what I’ve seen for a couple of years.
    Gained 60% after 33 min.
    73kW at 67%, this would have been about 50kW before this last update.
    50kW at 80%, this would have been 30’s before. 38 minutes. Usually I would continue a trip when charging has dropped to 50kW. This is now ~185 rated miles but only ~160 practical miles.

    After reading this, was very anxious to see if the update would improve supercharger experience so that trips would be feasible in the future. Very disappointed in data.
    2015 S85D with 2020.48.37.1 air temp 67. I was not sharing SC with anyone else.
    Tracked battery charge percentage and level. Started at 29%, only saw 37 KW, slowly ramped up to 47 KW and plateaued there. Stopped charging at 50%. 6 months ago, was seeing around 58 KW at the same location.
