Not sure it would matter too much at first in NZ as most EVs are leafs with Chademo, but yeah might help out some of the more modern other cars etc.

Range and battery unknowns have been my main reasons for sticking with ICE. Range is becoming less of an issue, but battery remains. For Tesla:

1. What is the average annual percentage of battery deterioration in NZ conditions? Eg, what % of range deterioration could be expected after 3 years?

2. At what age would battery replacement be likely or required?

3. Is there any information on likely cost to upgrade/replace older batteries?

Or is it too early to answer 2 and 3 yet?

Depends on which vehicle and cells. We have 4 year old model 3's in USA and no problem.

The Panasonic cells are good for 2-3000 charges, but the LFP cells in the new SR+ are 5000 or more, which is stupid amounts of kms

We have model S on 400,000 kms and no problems etc.

I dont expect to ever have to worry about battery replacement on mine

Here's a free piece of advice - there's a website called Google (www.google.co.nz) on which you can search for answers to questions you may have... What will they think of next?!

1. It's hard to say, Tesla doesn't make degradation visible. As a result, people use the "range when charged to 100%" vs rated range when new as an indicator of degradation. However this isn't very accurate as this number will fluctuate, especially if you're always around the same charge level every day. This prevents the BMS from getting a good view of the battery range and it starts to guess. This happened with mine so I did the recommended calibration and I went from looking like I had around 10% degradation to 3%. Had I done the calibration method a few more times it probably would have improved further. The car is now 18 months old.

2. I don't expect to ever have to replace the battery. There are Tesla's in the US and Europe that are well over 500,000km on a single pack and they still have over 90% of their factory capacity. Tesla thermally manages their packs and it has proven to work to minimise wear.

3. Battery packs get cheaper every year. Tesla has a 8 year/162k km (8 year/192k km for the LR/Perf) warranty for the battery so if anything happens to it or it somehow drops below 70% of the factory capacity Tesla will replace it.

Fair point, why not shut down GZ and redirect all questions to Google.

But sometimes it’s nicer to chat with a person, rather than hand over even more data to an algorithm. You know, just like the good old days. This is a discussion forum, why discourage discussion?

is the LFP only on the base model 3?

Yes, its less energy dense so takes up as much room as the 82kwh normal battery (with 55kwh or so).

Tabless cells go in Cybertruck, then Model S/X then Model 3/Y. So that is still years away. As are all those solid state fantasies. They will go into supercars 1st then the top of the line models and sometime 10y from now you might get them in normal cars.

So wouldn't hold my breath and go for LoiFePo which are definitely my favourite batt chemistry.

AFIK the first vehicles supposedly with tabless 4680s are the Berlin model Ys end of the year but at this point who knows.

It's a toss up between the Semi, Cybertruck and Model Y in Berlin for being the first this year to receive the 4680 cells. There was a report yesterday saying that the Semi is about to start limited production so if that's true it may be the winner.
