I’ll hazard a guess that you have a new model 3LR, or a new 100D, and live in a warm climate. Consider yourself lucky or at least fortunate enough to have a better car then some. The older batteries, especially smaller ones like the 60s, 70s, and the problematic 90s, charge much slower, especially above 50%. Last week I got 20 KW above 80%, even though I can get 115 KW initially at low SOC. I have a 2015 S70D. Furthermore, colder temperatures can really affect rates. For example, last winter I drove 110 mi from my garage to the SC at 0F. Upon arrival, I charged pretty much like normal summer temperatures because the batteries were relatively warm from the drive (even though I used most of a full charge due to the cold and my excessive heater use
). There was another Tesla trying to charge, also at low SOC, but had spent the night out in the cold, not plugged in and very cold soaked, just a few miles from the SC. Before I had arrived, that owner had been plugged in and waiting an hour for the battery to warm up, and still had another hour to go to get enough charge to continue on his trip. The car limited the charging rate until the battery heater was able to warm the massive battery. Note to all owners: Immediately charge to 90% or so upon arriving at a charging station in the winter. Don’t wait until morning otherwise you may need an extra hour or two.Sorry for the long post. Bottom line: Rates vary due to battery temperature (not necessarily ambient), SOC, size, age, and station (max output, bad nozzle, sharing). People have posted a few graphs showing the rates as a function of SOC and battery size, giving more reasons to buy the larger battery.
