Optimal charging scheme for battery longevity

Before posting I have searched the forums but noe quite found the answer. What's your opinion on optimal charing scheme? I for example plan on getting the 300 mile pack, will mostly though drive daily less than 100 miles and only occasionally long drives. I have the option to charge at home as well as at work. Will it be better for me to charge to full (not range mode) every time I have the chance (i.e. at night + at work) or is there a "magic percentage" to which I should let the battery discharge before charging? Is it good to ever intentionally let the battery become almost completely discharged or is there no point in this? (I have read in a battery app on my IPhone that it is actually recommended to once a month let the battery become 80% discharged but don't know if this is really true?).

So basically my question is: In theory, if you could stop and charge anytime, anyhere, for as long as you wanted, what would be the best scheme for charing for maximum battery life?

Also one more question: If you have an "aggressive" driving style (espes. with the sports version) and often "floor it" thus putting maximum strain on the battery, will this affect battery life?

To address part of your question, if it's anything like the Roadster, the normal charging mode for Model S will be about 80% and you'll be advised to plug it in every night.

As for the aggressive drive, again, with the Roadster as a guide, I don't think there'll be a problem. The reason they're going to require the 300 mile pack is to provide enough juice, quickly enough, for the performance mode drive train.

I'm buying the 300 mile pack for the same reason you are Johan. MORE FREAKING POWER!!! lol

From what I understand the drive train (and hence engine) will be exactly the same for the 160, 230, 300 and 300 sport version but the "300 sport" will have better cooling of the battery which allows it to deliver an even higher current (Amperes) than the standard battery, therebay making the engine/drivetrain even faster. Is this correct?

I found the first page below pretty enlightening.

Note that this commentary is on the Roadster. IMO, they should make an official and updated version for Model S.

Your link is an absolutely amazing post that answers all my questions and some more :) Thanks! Most likely all of the info there goes for the Model S as well.

As one can see from the detailed advice about battery procedures,
this is way too complicated for the average user. A fault of the nature of these types of batteries.

Good thing there's a computer nearby. An app with various options would be close enough. You choose:

  1. Normal (don't know when I'm going to use the car or for what)
  2. Will be going to [Destination] at [HH:MM] [OneWay|RoundTrip]
  3. Big trip at [HH:MM] =} maximum charge
  4. In storage

The computer does the right thing.

I wouldn't characterize it that way.

The original post was directed at helping an OCD consumer in maximizing battery life. It's a deep answer because science is complicated.

For normal folk, just "plug it in every night" and don't choose weird settings should be fine.
