You can use the Tessie app without without waking up the car.I understand this and intentionally open the app to wake it up. Loosing some SoC is not a big deal for me.
2) keep the main battery charged around 50%-60% is best for its longevity while it's in storage
Generally lower state-of-charge (but not below 0%) is better in terms of avoiding battery degradation over time. For NCA batteries, it is best to minimize time over 55%. For LFP batteries, it is best to minimize time over 70%, although it may matter less than with NCA batteries.keep the main battery charged around 50%-60% is best for its longevity while it's in storage
I also have a Model 3 RWD with the LFP battery. I've had the car a little over 1 year and its my first EV so I'm still learning. I tend to over analyze things, but I think your strategy looks good to me.I believe the important part is to really understand what's good for the main battery when it's in storage for sometimes.
My understanding are:
1) do not let the main battery goes down to 0% as it will also stop charging the LV battery. If the LV battery is dead, you cannot even open its door, trunk, etc....
2) keep the main battery charged around 50%-60% is best for its longevity while it's in storage
3) charge it to 100% for the BMS to re calibrate for accurate assessment of battery SoC before one resumes driving the car.
With these understandings:
1) I will leave home with SoC around 50% or higher (whatever SoC is at that time).
2) Set charge limit to 50%, leave the car plugged in. Charging may NEVER happen if SoC did not go below 50% limit during vacation.
3) A day before going home, set charge limit to 100% to get full charge and BMS calibration.
The Long Range (and Performance) has another battery.Um, I have a 2022 M3 LR. This is the first I'm hearing about needing to charge to 100% on a weekly (or other regular basis). I was told by the agent who did our sale that we should charge only to 80%. Have I been doing it wrong?
It's the M3 RWD (with LFP battery) that Tesla recommends charging to 100% at least weekly. Your car's charge screen will show the recommended daily charge level.Um, I have a 2022 M3 LR.
