So I am trying to wrap my head around supercharging. I see pretty much every post discuss how supercharging is bad for the battery. However, I guess I am just lost on that. Why? My understanding is the BMS actively controls charging levels. I also wonder if supercharging issues matter for older Teslas. For example, mine maxes at Superchargers at about 115kw. That charging speed drops of course as the battery fills up and the majority of my fill-up is probably between 60-80kw levels.
My "battery" history [using mile history as indicator for wear on battery and frequency of charges] is as follows:
Produced August, 2016
1st Registration: North Carolina: October 5, 2017: 11,168 miles [on another thread it was pointed out given the 12 month delay from registration and production it was likely a demo/show model]
2nd Carfax update: North Carolina: April 25, 2019: 30, 328 miles
3rd Carfax update: Florida: May 30, 2020: 36, 213 miles [purchased as a fleet vehicle]
4th Carfax update: Florida: June 26, 2023: 94,601 miles [sold to the dealership I bought it from]
My 2016 Model S P100D retailed with a 315 mile range. When I received it with the ~95k miles it has, at 100% charge (per my request to see what its max range is) it had a range of 272 miles. Approximately, 12.7% degradation.
I charge it to 85%, and by the time I get home it is at 80% as I park in my spot so it never sits higher than 80% SOC. I run it down usually to around 35-50% and by then we normally are out shopping and I refill it while we are in the store.
I have no idea what type of charging they used with either the original owner or when it was used as a fleet vehicle. Regardless, with FUSC that I have and the fact that I live in an apartment with no charging stations, I only fill up on superchargers.
I am wondering if anyone can explain if or why supercharging would deteriorate the battery given the advanced BMS system Teslas have that control charge rates--especially given the lower max rate my older model caps at. Or, if it does on newer cars that receive around double the charging speed mine can, are such concerns for my 2016 vehicle are misplaced? Again, I know everyone says supercharges kill batteries but it seems usually that is just stated without any empiracal evidence which takes into account Tesla's incredibly advanced BMS as well as the variations on charging speeds found in older vehicles.
With all that being said, I know zero about this stuff so that's why I am asking all of you to educate me! Thanks!!
