It’s to warm the cabin. The battery may be minimally warmed more as a side benefit but it’s not the primary purpose of departure preconditioning.Departure time is to warm battery so we get better performance right? If one drives the car when it's cold does it add to degradation?
The car doesnt warm the battery unless its sbout freezing, and in that case only to about 5C above freezing.Departure time is to warm battery so we get better performance right?
Nope.If one drives the car when it's cold does it add to degradation?
So warm battery is only beneficial for performance and we want the charging to end around the same or before we start driving?The car doesnt warm the battery unless its sbout freezing, and in that case only to about 5C above freezing.
Warm battery is performed by charging late with max available power.
If your TOU window ends much before you leave then just charge when it’s cheapest. But if you leave at a consistent time everyday then consider changing to departure off peak charging instead of having it start charging at 12 am.So warm battery is only beneficial for performance and we want the charging to end around the same or before we start driving?
I start charging at 12AM for rates at home and it would be done much earlier than I hot the road. Also I might never hit the road the day after.
Should I try to start charging even later than 12AM to synchronize with departure?
And if I cannot do this and keep doing 12 AM and somedays even not charging at all, it won't hurt since this is only for performance not for battery degradation anyway?
Ok, now that we have our car back from Tesla warranty service, it seems I was confused by our charge screen. As others have suggested, it only says "80% recommended for daily driving" when I move setting for "charge from solar" above 80%. We never set the normal charge that high, and for two years we kept our 2021 Model 3 at 70% except when leaving for a road trip. So, we'll just go back to a similar regimen, and won't set the opportunistic "charge on solar" feature above 80%. Mystery resolved.Could you post a picture of that?
When not driving, the colder the better fit the battery.So warm battery is only beneficial for performance and we want the charging to end around the same or before we start driving?
For low rates and stuff you need to figure it out for your self. The compromise between cheap and low degradation can only you weigh.I start charging at 12AM for rates at home and it would be done much earlier than I hot the road. Also I might never hit the road the day after.

How do you see it? I do see it in 17 but in the new car that meter is gone.In -20C after a Supercharging I drove highway AP speed at about 185 Wh/km in one direction. On the return the battery was cold. Still same temperature, same speed and road at sea level, and absolutely no wind I had 260Wh/km on the other way.
These values was from my M3P. You can use ”cards” or look at the ”trips” or what it would be called in english. Shows all consumption and ODO.How do you see it? I do see it in 17 but in the new car that meter is gone.
This is a shame that app is gone.These values was from my M3P. You can use ”cards” or look at the ”trips” or what it would be called in english. Shows all consumption and ODO.
In the Model S Plaid, its ”trips” only.
Nope, not helping the battery with that.BTW should I ever charge to high percentages for the health?
The only thing charging to 100% does is calibrate your BMS. It does not magically make your car drive farther. Maybe once a year I go on a long enough roadtrip to really do a proper calibration. To really get clean numbers ideally you would get to 100%, then drive it down to ~10% (or lower) and then charge it back up to 100%, then back down again. As mentioned I can only justify doing this on road trips. Some say just put it up to 100%, let it sit for a hour or so to really balance the cells, then drive it down under 90% and you're fine. I don't often deep cycle the battery, but when I do its only to get a good battery calibration. 2 passes of 100% charge back down to single digit % and back to 100% is enough to get the BMS adjusted.Also once a while should I charge to 100%? (or anything between 100 and 55, if I keep doing 55%)Is there any benefit?
I am in Canada and during the winter I want my charging to end at 7 am as that is when my electricity low price ends and that is a bit before I leave home. When the ambient temperature is low it is better to have a nice warm battery so you don't have limited regen. But I don't imagine that is an issue in San Diego very often, Toronto is a different story.So warm battery is only beneficial for performance and we want the charging to end around the same or before we start driving?

For a classic Tesla (pre-2019 or so) or any with the same lithium ion battery, keeping the battery between 70% and 20% for daily use (or maybe a bit less on the top end if your daily mileage can support that) is best.Hi, sorry to bump this up, but after reading many pages I am not clear -- so many different recommendations. for an original P85 (battery replaced with a new one 5-6 years ago), what is the best method to prolong the battery?
I see references to 50-55%, but that means charge to that as max and how low is too low?
If anyone can summarize the current thinking I would greatly appreciate it.
