Yes, I do get that plugged in is the best option, but I am more curious about what the best strategy is when you can't plug in, but at the same time would like to maintain battery health.
I would say to get the battery to around a 90% charge so that it'll have power to keep the battery warm if it gets cold. At the same time parking in a garage or somewhere to keep the temperature consistently warmer would probably help. You could also add a battery tender to the 12V battery if you really wanted.
plug it in to a 110 outletI have also heard that plugging in is always the best way to have a happy Tesla, it is however not always possible.
I don't have a charger where I live, so it is not a option for me. What would people recommend for going away for 7-10 days without the charging option?
I was thinking to aim for ~55% charge when I park at home (heated parking garage) so It would be ~50% after 7-10 days with power saving on and always connected off.
For a week, don't sweat it, just leave it plugged in anywhere in the daily section of the slider. For several weeks, set the slider to the lowest point and leave it plugged in. The only reason to plug it in to a 110V outlet is if you are taking up a shared charging stall, otherwise there is no benefit. When left in, charging will happen about once every two days for a short period of time. Range mode should be turned off in case the weather turns nasty (assumes outside parking).
I was in your situation for nine months. I charged to ~90% before leaving, washed the car, covered the car with the Tesla car cover and left. It was alone in my garage (~70 F mostly) for two to three months. It suffered no damage, and still have the same 100% range that it did when I bought it, 253 miles (P85D) just as originally specified.Well, it's a new garage so it pretty much keep the temperature around 15-20°C (59-68°F) all year round, so I don't think the battery temperature management system will try to adjust the temperature.
I just had it parked for 76 hours for the first time and I only lost 1% on the battery, I guess it would be more significant if the battery needed cooling/heating.
It's just my understanding that I would keep battery in the best condition, when standing still for awhile, if I keep it around 50% and letting it stand with either high or low SOC could be a problem in the long run?
That's no problem unless the weather is very, very cold. Then it can use quite a bit of power keeping the battery warm.I don't have the possibility to plug it into any type of electric outlet whatsoever. But I guess I don't have to be too concerned when it is just for a week or so.
