Tesla should not sell a performance model that advertises 3 seconds to 60 assuming 90 percent charge and then at the same time sell me a car that will have range degradation accelerate by keeping the soc at 90.
As thread is about how to preserve the battery and what can be expected and how to maintain battery health of course we discuss the degrading mechanisms and how they affect our batteries.
The different tips about the best charging scedule differs as people have different theories and/or knowledge. One thing is common though:
it is not Teslas statements.
This is what Tesla says in my M3P 2021 manual:
If you let the SOC drain to 0% other compoments can get damaged(12V battery). Dont let the battery go down to 0%.
Thats it. Nothing more.
At Teslas homepage, the support site says:
Your daily recommended charging limit will be displayed on the car’s touchscreen. If you need the full range of your battery for a long-distance trip, you can increase the limit to 100% as necessary.
In my M3P, the ”Daily” is up to 90%.
So if you need the power, charge to 90%.
And after reading this thread you know that you probably will have higher degradation if you do that. You follow teslas simple tips and you are guaranteed 70% capacity to the warranty limit.
A little OT: For the ICE cars, the advertised 0-100 performance will be the very best they can do at optimal conditions. For example engine power reduces with higher temperatures due to
warm air is thin air = less power. At 100degrees F most ICE cars produce less power due to this.
The ICE will probably not keep the 0-100 value at 100F but the Tesla probably do.
Also the advertised ICE power is only met at a specific rpm. Same with the torque, its said for example 400Nm(or ft-lbs) but if I rew to 7000rpm I will not get 400Nm. Most people probably accept this as they are used to/did learn about this long time ago.
Changing to EV’s will be a conversion as they is not the same as a ICE car. There will be differences we need to accept.
If you cannot accept the raw physics of the todays batteries you might need to wait until they have fixed the issues you dont accept.
Or buy a Model S Plaid, as it keeps the power very well to lower SOC’s. But of course there will be someone that cannot accept that the Plaid looses performance at really low SOC.
There might be a thread about the physics that cause the performance drops with decreasing battery state of charge, if not it probably could be a good idea to start a thread that can cover the basic principles behind and what to expect about performance.
