Of course they do. When Tesla started selling cars the oil interests launched a big campaign to try to suppress sales. Range anxiety, charging time, lack of charging infrastructure, cost and safety (battery fires) were the subjects of much of the disinformation they spread. While most of the "FUD" has been forgotten at this point some of it is still around. And FUD or no there are situations where people don't want to spend more than a couple of minutes refueling their vehicles. The average Super Charger visit seems to be 20 - 30 minutes. Getting that down to 10 - 20 minutes would clearly be to any BEV maker's advantage and 5 - 10 would be even better. This can be done but there are engineering challenges as mundane as the size of the conductors required in the charging cable and as subtle as the effects of high charging rates on battery longevity, The manufacturer has to decide where he wants to be in this trade space.Tesla does "advertise" fast charging capabilities and "range" to enhance sales and image.
Yes, they have. I even got a warning on the screen (2018 X) to the effect that I had charged to 90% (L 2) several times in a row and advising me that if I didn't tone it down the car would,I have read of owners having their SC experience throttled.
Tesla used to sell EVSE which could be connected to circuits up to 100 A. EVSE must be derated to 80% of circuit capacity so that meant maximum charging at 80 A and some old Model S could accept charge at that rate. Newer TESLA EVSE (and it seems that of other manufacturers too) is limited to 60 A circuits, Derated that's 48 A which gives the 11.52 kW number which is the number Rivian publishes.I am aware that they reduced the L2 capacity to 11.3kW(is that the number a 60 amp, 240V line can create?) from some higher number.
Within the fleet. The car calculates its estimated full charge range at the end of each charge. This information is made available through the API. We do not know for certain that Rivian will do the same but assume they will. There are a couple of third party applications that collect this data from your car and others in the fleet. This data gets published from time to time in various places resulting in plots like the one at https://www.teslarati.com/tesla-bat.../tesla-battery-degradation-data-points-chart/.I'm not positive that I am reading significant degradation of their battery packs (-20%) over time but where is the data for this?
At least 2 applications I know of will plot the data for your car and one also plots the 'fleet' data for your model with the caveat being that the 'fleet' is others who own your model and subscribe to this app's service.
Note that in this case the 'fleet' is only 19 other cars.
