I'll just add another point for people new to the EV game. Almost all Teslas will not meet their claimed performance specs unless they are close to fully charged. Let's say 95% or better. If you want to minimize battery degradation, you'll want to be around a 50% average state of charge (SoC) if you have a long range or P version (non-LFP battery).
So maybe you charged up to 60% for the day, return home about 40%, your avg SoC will be about 50%. No point charging up to 80-90% if you are only going to drive 50 miles for the day. Extra wear and tear on your battery for nothing. High states of charge, in high temps, cause very rapid battery degradation so don't charge up the car to 90% and let it set for days in hot weather. Never good to do in general, but hot weather is very detrimental to battery health.
Keeping your battery avg SoC lower, your degradation will be less. My M3 and MS LR, had less than 1% degradation in 15 months of ownership and about 9k miles. My MY LR which is about 30 months old, 55k miles now, has 6% degradation. Most of its degradation occurred before I had good charging hygiene. It has also seen a lot of supercharger use. All cars are in a very hot climate Texas. If you want to know more, search for posts by AAKEE. He has done more research on this than me. I read some posts by him a few years ago and altered my charging habits and the results are obvious.
The downside to a lower SoC is the power output is reduced and your acceleration times are impacted. At about 50% SoC, on my MY LR with boost, I had lost about 0.4-0.5 seconds off the 0-60 time. Basically with boost, at 50% SoC, it was a little quicker than stock at 100% SoC and no boost. The impact on the 0-60 times is less however than the impact on acceleration at higher speeds.
The only car so far I didn't see this happen to, was my 2022 MS LR. It didn't really care what the SoC was as the battery pack was built for the Plaid with about 50% more power so no problem keeping the LR going even at a reduced SoC. I don't have enough data on my Plaid to say and it is quick as hell regardless so less of a concern anyway.
That was one of the biggest benefits of boost on my 3 and Y is that even at low SoC, they were better than stock every was fresh off the charge. The MYP and M3P start quicker but even at 50%, they are still fun to drive. All the 3's and Y's at about 60-70 mph are going to definitely feel more sluggish accelerating when at a 50% charge. The MS LR again was almost the same as 100% charge. Not enough data on my Plaid to draw any inclusions. I can saw that even at a 30% charge, it is faster than my MS LR ever was at any speed range.
. When bring that much doe to the table, might as well call, and bring home the prize.
