With all the talk about cars with SC equipment requiring calibration etc., I wonder whether battery replacement has become more complex. Will battery upgrades now require major car surgery or will quick-swap still be possible?
Well, we don't know what "calibration" consists of. It might be the cables and the battery has nothing to do with it.
As far as quick swapping goes, that was mentioned early in the development cycle and has been downplayed ever since. It's never seemed to me to be viable if for no other reason than the massive amount of capital it would take to have batteries at every location. (There's also the old battery being leased in exchange for your new battery problem.) I really don't understand why people keep bringing it up.
Battery swapping only works if you don't own the battery to start with--and no one has proven yet that it's a viable model. It's being tried in Europe but the distances there are much shorter so the capital investment is much smaller than it would be in North America.
My question isn't really centered around instant swap. It has to do with the ability to easily upgrade the battery some years down the line. Has the SC hardware complicated that in any way?
No. The SC hardware was always on the table, what's changed is the way they are charging for it. It won't make any difference in battery replacement.
mboedigh----suggest that you get all your upgrade questions answered in writing at this point from Tesla. Especially if you are buying the 60Kw equipped S---hoping to upgrade to an 85Kw pack in the future.
Want to make sure the basic Car of the model S for the 60 & 85Kw pack options are the same---for upgrading and supercharging----so you know if you have to do major surgery or not.
It's been said before that upgrading from one battery to another will involve shop time. This has never NOT been the case.
Why do you think Tesla advises people to consider their choice of battery carefully, with an eye towards what ranges they'll want to drive in the future?
Yes, I beleive Tesla reps have said in the past that it's possible to have battery swapping in the Model S, but I believe they were saying that more in the spirit of "Well, we can't rule that out" rather than, "Yes, we have totally designed and planned around that eventuality"
I really think people ought to NOT rely on the possibility that we can swap batteries. Yes, I'm assuming that it is "swappable" in the case of needing a replacement for damage or defect, etc, but not as kind of a standard upgrade.
I am even assuming that the Model S will be "left in the dust" so to speak should a future Tesla car offer battery swapping and/or upgrading, if Tesla decides to go that way. This is the first car that Tesla is building completely, and unless they have kept the plans sort of secret, they are not designing the car, the service of the car, the retailing of the car, etc, with the idea that we can upgrade or swap the batteries as a high priority.
If Tesla thinks that would be a good idea for a future car, then I would really expect some things to be designed differently. Battery tech (and related systems like chargers and cooling/heating) may be significantly different then, and there could even be new industry standards that exist for some or all of these things. Maybe the retail experience will be different too. Maybe you will buy the battery "seperately" with an array of choices from different manufacturer's, for example. Who knows.
I would not expect, nor would I want, Tesla to be hampered by an to arbitrarily desire to make whatever solutions they come up with for new cars to be backwards compatible with their "old" Model S 1.0's.
