I logged all my Supercharging sessions of the last months using Teslafi and compared it to Bjorn's recent video of his 90 Supercharging. Instead of using percentages or miles or a constantly changing charge rate I used kWh is a basis to compare. In the end that's what counts. How long does it take to recharge a certain amount of energy. To make it fair and equal, I looked at Supercharging session in my logs that also started at around 10% battery. That is also a very realistic level of battery when you arrive at a Supercharger at a trip. Enegy.......85...........90 32 kWh.....22 min....23 min 35 kWh.....25 min....25 min 40 kWh.....33 min....28 min 46 kWh.....38 min....32 min 52 kWh.....39 min....37 min Of course there are always some variations and rounding errors, but it shows that even so the 90 is peak limited to around 95 kW, overall the charge rate is not worse because it maintains a higher rate over a longer time compared to my old 85. For the most common case (adding around 45 kWh) the 90 is a few minutes faster. I you arrive at almost 0% battery the situation would probably be a little different. The 90 starts to charge slow when the battery is low and only reaches 90 kW when the battery is about at 15%. The old 85 starts with 115 kW and stays above 100 to about 20%. But then the taper kicks in and the rate drops quite a bit. In other words, when arriving really low and only needing let's say half a charge (to reach the next Supercharger) the 85 might have a slight advantage in charging speed, but in the most common situations, the 90 will be faster by a few minutes. If you charge to a higher level the 90 is definitely ahead because it maintains a higher charge rate while the 85 drops significantly. In most of the cases you are charging faster in a 90 even though the peak charge rate never reaches the level it does on the old batteries.
