Let's say I was going out of town for a week or longer, would it be best to leave the MS plugged in while gone (garage 240v outlet) or should the car be left unplugged?
It is the manual. Several times. In bold print. Leave the car plugged in whenever possible. But you don't need to worry about the charge level for a week. The 50% is for long term storage.Plugged in definitely. With charge level set to 50 or 60%. This should be in manual!!!!
As noted many times here, the cars used to come with a card that said "A connected Model S is a happy Model S". With all the times this question gets asked, I don't understand why Tesla stopped including that with the deliveries.
I asked my ownership advisor if there was a manual in PDF form I could review before my car is delivered next month and he said "we do not have an owner's manual in pdf or anything like that" once again this forum has provided better information than I can get from a Tesla employee. Thank you! Now I have a 183 page PDF to read ...Posted page 122 of this manual - https://my.teslamotors.com/sites/de...touchscreen_7.0_das_ap_na_r20151028_en_us.pdf - but im sure i've seen it in the onboard manual as well:
About the Battery
Model S has one of the most sophisticatedbattery systems in the world. The mostimportant way to preserve the Battery is toLEAVE YOUR Model S PLUGGED IN when youare not using it. This is particularly important ifyou are not planning to drive Model S forseveral weeks. When plugged in, Model Swakes up when needed to automaticallymaintain a charge level that maximizes thelifetime of the Battery.There is no advantage to waiting until theBattery’s level is low before charging. In fact,the Battery performs best when chargedregularly.Note: If the Model S Battery becomescompletely discharged in a situation in whichtowing is required, the owner is responsiblefor towing expenses.
