Aftermarket 800V battery?

[SergeyIndy]

Assuming not too much changed platform wise, best you could get is battery from the 2025 facelift.

I am pretty sure that 2025 battery is not compatible with earlier models as you need more than just a battery, that is different chemistry, with all the components around it to manage it.

The best case I see long term is that we can replace the modules with compatible ones (not entire battery) that will cost less in time. However, I do not see Porsche spending resources to say develop better modules and then provide a software update to go along with them and offer it as an upgrade service to keep our original cars on the road longer with same or better range.

If I find myself in the unfortunate position of needing a battery outside of warranty, I'll probably get one off eBay from a wreck.

Because as others noted, a new battery will cost more than the car is worth.

Or, you will buy your third Taycan.

Ha! No way. I’m really hoping the E-Boxster is good.

I am looking forward to the Cayman E being offered in the upcoming year, but I hope it looks better than the test mule I have seen of late lapping the Ring.

This is what I hope for as well. Would love to buy 120kWh aftermarket battery for 20k USD in 10 years. In terms of effeciency and power there is not much more significants improvements you can do in EVs anyways. Taycan 3 will be pretty much same as this one except software, self driving and battery stuff.

My hopes too. As long as the battery does not completely fail after the 8 year warranty then I’m good. It would be nice to know I have the option to replace the battery for $20K or less to get the same or better range.
I would guess if the next generation battery chemistry/design doubles the range then you could be given the option of a more efficient smaller kWh battery 1/2 the size & weight @ 1/2 the price with the same range or a full size battery at the same size & weight with double the range at double the price as long as it’s less than $20K for either I’d be happy. For my 2021 Taycan, in Southern California, cars last forever. No rust unless you live by the ocean. I hand wash it every 2-3 weeks just to clean the light film of dust on it. I plan to baby her for the next 10-20 years until I can no longer drive or die…

I can’t find it right now, but on the other forum I’ve read of cases of mixed chemistry batteries already being put in taycans, directly by porsche. So I don’t think the chemistry would be a problem, but you would obviously not get all much more from it, beside the actual increased capacity - if that. As far as I know the actual battery enclosure & shape is all the same, layout and battery cells too

I am with you...I tend to seep my cars for at least 10 years/250k miles....I hope my 2020 4S willl break the record.

Do you have any credible sources confirming a J1.2 battery can fit into a J1.1 car? Or just wishful thinking?

That's even further delayed as Porsche's intended battery manufacturer just folded its tents.

As far as I've seen at dealers in Switzerland, battery enclosure is exactly the same minus the protection shield. And I highly doubt they invented a brand new electricity delivery method / interface / plugs.

And as mentioned above, according to people one the other forum, Porsche already puts new chemistry modules in old taycans, that have the old chemistry, resulting in "mixed" batteries.

So realistically, all you'd have to do is replace all the modules 1 by 1.

But as you've said previously, people actually doing this would be non-existent, as taycan is not a high volume car.

If the battery is in fact a replacement, someone would pay Porsche for a new battery to get more range (J1.2 has a large capacity battery). Perhaps when they need to get a new battery anyways (like there is a >3mm dent in it), the customer would be offered a choice to pay an extra grand or a few to upgrade to more range. Only once that is done, can we know that the new battery would "just work".

My Taycan has about 3 years of life, 86.000km and I truly love it. It's hard to think of another car to replace mine and I'll certainly won't buy the same car again. So far winter time is the enemy since I've never seen ranges above 360km on normal driving, and really fast driving is gets down to 300km. From 100%.

My question is..

Do you think there are going to be aftermarket companies who will create more efficient and lighter 800V batteries? It's a dream to have 200kg less, more efficient, 600km range on an older Taycan. Batteries are not writen in any official document, only engine code, so fitting a new battery can't be that hard. Any opinions?

I think probably, yes.
More likely to be either lighter for same capacity or bigger capacity at the same weight but I see no reason why it would not be a possibility. It may even be cheaper.

I am more concerned about digital electronics not being repairable myself.

I have traditional HiFi equipment still working well after decades but my high tech DSP controlled wide frequency response but small speakers stopped being hardware compatible with the latest firmware at 5 years old.
They still work fine with the old firmware, so aren't broken, but if something does fail I doubt spares will be available in the way they used to be.

In fact my view is that any modern electronic item has such a short life it needs to be much, much cheaper than equivalent traditional items were to be considered reasonable value for money.

This means modern high tech cars are pretty well all poor value IMO.

I don't either, I expect this sort of thing to come in the future from specialist tuning firms which will develop older cars in the way they always have.
Given my experience in racing nowadays good hands on mechanics are hard to find whereas young clever and enthusiastic computer modellers are two a penny so the software will probably be easier than the hardware but using the same enclosure etc may well be feasible.

I do hope that EVs don't end up killing the classic car future.

The way to look at EVs is how you look at phones. Consumables, you have them 1-3 years, and replace it. Hence leasing is the best way going forward.

Not at Porsche prices.
