it thinks there is 58 kWh in the battery. Now we know there's a buffer on top of this.
As shown in the other thread, actually this number includes the buffer.
so that would put my pack at 61.5 kWh which is about the
62kWh a mid range was reported to have (of course Tesla doesn't publish these numbers, so it's hard to know).
As you have discovered, no, you should not add this 2.5kWh buffer (it’s always around 4.5-4.7% of the full battery size) to this calculation. Your battery has 58kWh capacity,
including the buffer.
. If it only charges to 200 or 210 or whatever when brand new, that makes you a little concerned about what it will charge to when the battery actually starts showing degradation.
Seems like a very reasonable concern. I have a hard time understanding people who say not to worry about the battery gauge number. It really matters! It is much better to have (for an AWD) 310 miles at a full charge than 285 miles! You very very likely have a lot more real-world range because you have more energy available! No one has shown that the cars displaying lower miles actually contain more energy per mile - and they very likely don’t. All else being equal, you want to see a larger number! If I’m stretching for a Supercharger, I definitely would prefer to see 10% projected arrival charge (very safe) over 5% (requires thought)!
Hopefully this is just a screw up with BMS programming from Tesla, but it has been going on since early summer, so at this point it seems like we just have to assume for now it represents true loss of capacity. And hope that we are wrong.
