Hi,
This is my first post, so sorry if I'm doubling up. I have looked for an answer to this question for awhile, and I haven't found much discussion on the issue.
I'm currently waiting for the Tesla S price to be announced in Australia. Unfortunately we don't get any govt incentive, so tossing up between the 60 and the 85kwh battery bank is going to be part of the equation unless the govt comes to the party soon.
What I'm interested to know is whether or not anyone else has bought the 85kwh battery, with the view of increasing the time before the bank is to be replaced. My thinking is that if the 85kwh battery will loose about 20% (or so) of its charge at about 8-10 years, then that puts it around the 60kwh level. I could then continue driving the car for another year or so, before it possibly went down to 40kwh, thereby giving several more years of serviceable life to the bank, and effectively meaning a substantial chunk of the upfront cost has been paid for by the fuel savings.
I currently use a stand alone home solar power system (with 1500AH battery banks). My understanding is that towards the end of their serviceable life, they'll gradually stop holding as much charge, but will still be good for years as I only tend to use about the first 10-15% of their capacity. I'm assuming that the tesla battery bank will be much the same.
Does anyone have any thoughts on this? I'm tempted to push out to the 85kwh battery bank on this basis alone, although the 60kwh battery is probably in the sweet spot for my usual holiday driving range and affordability.
Thanks very much.
regards,
craby
