Hey Stew, what’s the code on SC for the 3 years free supercharging? I bought a 21 with free SC with code SC05, but I know there were no promos going on then, so I wonder if the free SC is limited time.E90alex - thanks for your reply.
We have 2 TESLAS. 1 with 3 yr free Supercharging and the other is charged @ home.
The free supercharge car goes to the supercharger about once a week and charges to 80%. The home charging car gets plugged in when my wife gets home after her day and is generally down to 30-40% SOC and gets charged back to 80%. The home charging happens about 2-3 times per week. Our rate is about 0.16 cents per kw which includes generation and delivery charges.
We are lucky here in PA. We get to shop for our electric provider so we can go with the lowest bidder and depending on the plan, switch without penalty whenever we like. It just takes a bit of time to evaluate all your options and clicking to switch.
Over the years we have saved over $3k in electric charges by switching to a cheaper supplier.
Let me throw the question back to you E90alex. What do u do and pay for electric?

Hopefully they bring it back@SoManyM3s I don't know any code on SC that your referring to.
The 3 year free Supercharging is from the end-of-2nd-quarter sales promo on the S and the X.
Would 55% on a daily basis be enough?personally I set my charge to 60% and i plug it in every night. But for rare long trips i always charge to 100% and i lowerer the chargin ammps and i time it so that it finishes charging to 100% right before the time i'm about to leave. reason for this is to cut down the supercharger stops plus i pay 14 cents per kw/h at home vs close to 50 cents at super chargers. Plus its good to charge to 100% every once in a while go the battery gets a good full balance charge.
1. Pick a number. Personally I charge to 75%. It hardly ever happens, but I want to be covered for those unscheduled longer-ish local trips.I am picking up a MXLR this week and do not want to repeat the mistakes. Does this make sense?
1. Keep charged to 50% for daily commutes (rarely exceeds 40 miles/day)
2. For shorter round trips (100mi - 180mi) charge 80% or below to avoid supercharging (my FUSC will transfer, but I want to avoid stopping to charge)
3. For longer round trips (200m or more), charge 100% when leaving home.
4. If supercharging cannot be avoided, arrive at the supercharger with 10-20%
I also saw comments that said it is preferrable to leave as soon as 100% is reached (when charging at home), what is the rationale behind this?
PS: I get that convenience trumps everything else, at the same time if I can make the charging fit my convenience and not sacrifice on battery life, I would take it.
No. If you need 90%, charge to 90%.The information here is useful, I wish there is a sticky thread for 'Best practices' on charging at home and supercharging.
On My 2016 Model S (75), I had been charging at 80% all along when I would likely have been OK with just 50%. But when I needed to make trips and did not want to trip to supercharge, I typically charge 100%.
My range when charged 100% had stayed at 232miles for the past couple of years.
Recently, I had to travel almost daily for couple of weeks (~130 miles) and so as not to hurt battery life, I started charging 90% instead of 100% but after the end of two weeks the range dropped by 10 miles! And based on the data provided by @AAKEE I think I made a mistake by charging to 90% for two weeks!(?).
Yes, and if possible charge late (next morning before the next drive) Not very important if you charge to 55% or less.I am picking up a MXLR this week and do not want to repeat the mistakes. Does this make sense?

No there is not. In normal temperatures 100% wear about the same as 80-90% or so.I also saw comments that said it is preferrable to leave as soon as 100% is reached (when charging at home), what is the rationale behind this?
Thats exactly what I recommend.PS: I get that convenience trumps everything else, at the same time if I can make the charging fit my convenience and not sacrifice on battery life, I would take it.
