New Battery monitoring software update?

[GTSS]

We already have J1.2 battery problems mentioned on this very forum. Still too early to tell if they are more reliable.

Porsche have gone further by redesigning the battery for J1.2 and then making it backwardly compatible. That's a good bit of engineering insurance.

It's just a new chemistry, same design, still made by LG poland. They updated because they had to, lg is no longer manufacturing the chemistry used in taycan my21-24.

It doesn't require so much "new" engineering for backards compatibility, as my20 already had older chemistry (albeit barely changed) than my21, while having same design, and newer modules have been already used in my20 for repairs and recalls for years - my my20 got 3 my23 modules in december.

So with all this being said, lg batteries made in poland have failed in preatty much ANY ev that has used them. It's why they did not use them for the macan EV and why they won't be using them for the 718 ev.

And likely when a real taycan 2 comes out, and not just a facelift, which will bring a new battery design, it will also not use LG anymore.

That's disappointing. Missed opportunity.

Ah. Bad news. Hadn't seen that.

I just brought my car in for a change to summer tires (expecting a major snowstorm in the next few weeks...?), and I got the WRW1 battery monitor installed along with a recommendation not to charge the battery to over 80%. I received a new battery in June 2024.

I just can't believe a major car company has an EV with a recall covering every single car they've sold in the first four years and I'm just getting this recommendation now, after driving the car for 48K miles and 4-1/2 years. Of course, there is no remedy other than 'just don't charge your car to over 80%. I know this affects us all, but I am just gobsmacked by the absolute incompetence of Porsche and how they are completely disregarding their customers. What exactly am I supposed to do if I continue to charge my car to 85%, as I've been doing for the last 4-1/2 years. I should reduce my daily charge to 80%, and if I'm going on a trip - don't charge above 80%? Certainly the 'recall' covers Porsche in case I have a fire. I just can't believe how badly they have messed this up. Taycan sales are down 40-50% and Porsche is completely deserving of this massive rejection of their product. Idiots.

Sorry about the rant, but I am quite intolerant of Porsche apologists who defend the brand pretty much regardless of how badly they perform. I'm a firm believer in a demanding customer driving excellence in products, and this is a prime example. OK, a few deep breaths and I'm good...?

How did you get this recommendation? Official recall, something on paper, a casual mention by the advisor when checking out, email, app notification, other? How was it worded? Did they say what would happen (or risk to happen) if you charge 80%?

Basically just a casual mention by the advisor - with rolled eyes. The dealer has been exemplary, and they are quite sympathetic with the situation I’ve had with my car (almost 160 days of ‘shop time’). I declined the other recalls for the cable and charger - I no longer use the Porsche piece of crap charger.

So nothing official, could be a rumor. Or it might have applied to one car they saw, and they recommend the limit to everyone? If talking to them again, ask if they have an official bulletin suggesting it, or is this a word-of-mouth spread message, or perhaps their own speculation.

It's been around four and a half months since the ARB6/7 recall began. Isn’t that enough time to develop software that can detect battery anomalies? In case that is even possible, of course.

Especially considering that LG, the battery manufacturer with years of experience, is likely involved. GM and Jaguar previously attempted similar software-based solutions—probably also with LG's support—and those efforts ultimately failed.

So the question is: did Porsche bring this situation upon itself, or was it pushed into it by someone else?

My Taycan received the WRW1 (improve external communications/online diagnostic capabilities) software update OTA today. 35 minutes.

It's to cover their warranty obligations, and a way to meet regulatory requirements. Warranty on Taycan batteries is 8 years, they don't want to continue to manufacture old batteries for warranty replacements. As for regulatory requirements, some countries require spare car parts to be available for a decade or longer, so they are covered if the new batteries fir old cars.

I got mine a few days ago. It was the very first OTA update for my car, outside of apps like weather. or calendar (which I never use, so don't even know what changed).

Oh yes I understand that.

Warranty is scary when dead product racks up like so much cordwood.

Been there.

This is actually quite confusing. My REPAIR ORDER cites BEV RECALL/CAMPAIGN WRW1, which I can't find anywhere searching the internet. I had a discussion with my SA and he said Porsche was recommending not to charge over 80%, but this may only be in the case if their newly installed software (which I declined) shows a problem. I didn't want them putting software in my car to cripple my charging to 80%, and at this point I really don't trust Porsche to do what's in my best interests. It's also possible that the software simply monitors your battery, and if there is a potential problem, they simply inform you. Not sure.

Did that, and maybe I'm stupid, but I still can't find a complete description of exactly what 'WRW1' is. It is some type of 'monitoring software', but I don't see a detailed description anywhere.
