Porsche Ordered to Buy Back Taycan That Charged at 9.6 kW, Not 11 kW

[Briguy]

10.2 - 10.4 kW is the effective charge rate at the battery (including overhead losses) when being fed a "raw" 11 kW (240V @ 48 amps) - the 9.6 cap is actually misleading - it's not 9.6 kw - it's a limit of 40 amps @ 240V - which ideally is 9.6 kW "raw" - this in practice shows up at the battery somewhere around 8.6-8.8 kW effective charge rate.

Yes the car could and did request 48 amps - you can see this in the 10.2 kW - and on some EVSE's they show the raw power "feed" at the EVSE which is 48 amps...

updated Taycan's (and the Macan EV) no longer request more than 40 amps in North American region because of an OTA update.

there is no question Taycan's used to allow 48 amps - there also is no question that Porsche for undisclosed reasons is capping North American charging at 40 amps…

the Cayenne EV is specified to be a 40 amp EV in north america, but porsche has repeated stated that it can charge wirelessly at 11 kW (48 amps) - it would be a sad joke in the Cayenne Ev can charge faster from it's wireless charging pad than it can plugged into a wall…but my guess is Porsche is as confused about those stats as they have always been about the Taycan's charging limits…

I documented the Taycan's original North American charging limits as 48 amps in Aug. of 2020 with this posting…it's taken 5+ years for Porsche to finally achieve clarity on the Taycan's North American charging rate/limiites - up until now it's been both 11 kW and 9.5 kW depending on the phase of the moon and who last updated the website…

here is my thread from Aug. of 2020 noting the 11 kW charge rate for my 2020 Taycan Turbo.

https://www.taycanforum.com/forum/threads/factual-report-just-data-11-kw-charge-rate.2220/

i collected relevant documentation that was submitted in my arbitration proceeding which pulled together the range of disclosures that i received and reviewed which supported the 11 kw specification.

It was not fuzzy or inconsistent. Porsche communicated the 11 kw home charging specifications very consistently. Happy to upload this package if there is interest.

the original US website (screen shots included in my original thread) had teh taycan's maximum charge rate specified as 9.6 kW…the US website has at various times listed int he OBC as both 9.6 and 11 kW - there has been no consistency

however what has been clear from the start is the Porsche never shipped a Taycan that was limited to 9.6 kW in North America until recently…

there is ample evidence and screen shots across many threads in this forum where Porsche is/was confused about the maximum charge rate of the Taycan - but the documentation often times was different that the actual product/vehicle/OBC behavior…

it was not unilt the 2022 Website that Porsche documented the US Taycan's as having a 11 kW OBC…prior to that they listed it as 9.6 on the technical specifications website for US products…

you can see it clearly in post #4 of this thread with forum date/time being Aug. of 2020

https://www.taycanforum.com/forum/t...-just-data-11-kw-charge-rate.2220/#post-30269

or this post from July of 2020 where 9.6 is featured in screen shots from Porsche's US website…

in the US at various times the Taycan has been listed as either having 9.6 OBC or an 11 kW OBC - but Porsche never shipped a product that limited the Taycan to 9.6 kW (until recent OTA and MY'2025 Taycan's)…

congrats on you getting Porsche to buy back your car and yes they ahve been confused and misleading - but they have never had a clear story based on ample evidence with date/time stamps in the this particluar history…

for better or worse Porsche Canada took the lead on this consistent 11 kw messaging. at least in Canada.

May of 2023 was the first time US Porsche websites listed Taycan as 11 kW OBC - until then it was always listed as 9.6 kW…

see screen shots w/date-time stamps in the original thread…

but the car alwasy behaved/allowed 11 kW regardless of the spec's published on the website…

Here are the 11 kW documents forming the core of the evidence for the arbitration

 

[Horizontally Opposed]

Hair splitting. You got rid of a great car. I’ve never had level 2 chg any faster than 8.9. Makes no daily difference.

 

[snstevens]

So I parted with my 2025 Taycan 4S Cross Turismo today, selling it back to Porsche as a result of an arbitration award issued under a system that operates in most Canadian provinces called CAMVAP (the Canadian Motor Vehicle Arbitration Plan).

For those unfamiliar with CAMVAP, it is an independent arbitration program that allows consumers who have experienced defects in their vehicles to seek an order requiring the manufacturer to repair the vehicle or, in appropriate circumstances, repurchase it.

The central issue in my case was not whether 9.6 kW charging is "good enough." Rather, it was whether Porsche represented the vehicle as having an 11 kW onboard charger while delivering a vehicle that could only charge at 9.6 kW. After months of discussions with Porsche, the company ultimately acknowledged in December 2025 that my vehicle could not achieve the published 11 kW specification and would charge only at 9.6 kW.

I entered the CAMVAP process only after many months of trying to find a solution that would allow the vehicle to meet the charging specifications under which it had been marketed and sold.

I took delivery of the car in August 2024. The buyback occurred on June 3, 2026.

For those interested in the financial side of the result, a CAMVAP buyback is not a refund of the original purchase price. The repurchase amount is determined by a formula based on the actual purchase price paid by the consumer (including taxes, freight, PDI and similar charges), reduced by a mileage deduction calculated as of the date of the arbitration hearing. In my case, with approximately 21,000 km on the vehicle, the buyback amount was roughly 90% of the original purchase price.

I will miss my 2025 Taycan despite the challenges I experienced during ownership. It is a beautiful car in many respects, and pursuing a buyback was never my preferred outcome. However, I was not prepared to accept a vehicle that could not meet the specifications under which it was represented and sold.

I am attaching a lightly redacted copy of the arbitration award. I have redacted only the names of individual participants and certain identifying information, as those individuals did not sign up for public disclosure.

I am happy to try to answer any questions fellow forum members may have about the process, the evidence, or the decision.

I feel two completely different ways about this post.

On the one hand I want to congratulate you on an outcome that is so clearly in your favor. Given your stated desires (i.e., 11 kW OBC or take the car back) it appears you got exactly the outcome you desired. Of course, the reason you could not get 11 kW OBC is that Porsche does not have an 11 kW OBC available at this time.

On the other hand, I don't see how the lack of an 11 kW OBC is meaningfully impacting you, me, or in fact any of us. Even if you had to charge 70 kW every day (you never really stated your use case so this is a wild guess), the difference in charge time between 9.6 kW and 11 kW is ~54 min (7.3 hours vs. 6.4 hours). We're still talking about a reasonable overnight charge. Since most of us don't charge 70 kW every night, the charge time difference is actually quite minimal (<20-30 min).

I would feel differently if you had purchased the 19.2 kW OBC which could deliver 70 kW in 3.6 hours vs. 7.3 hrs - 50% less time. I understand it wasn't available in the 2025 model year, but I'm using it as an example since some on this forum did purchase that OBC.

What I'm getting at is that I'm missing the compelling rationale for your decision to take a buyback. Speaking personally, I would NOT have wanted a buyback. My Taycan 4s is the best handling, best driving experience, and best looking car I've ever owned. In your shoes I would have asked for a financial accommodation of some sort, not a repurchase. But that's me.

 

[ItsNot AboutTheMoney]

@Briguy I was wondering what replacement vehicle did you come out with?
Also, I’m curious whether or not you were blacklisted by Porsche.

 

[whitex]

it's not 9.6 kw - it's a limit of 40 amps @ 240V - which ideally is 9.6 kW "raw" - this in practice shows up at the battery somewhere around 8.6-8.8 kW effective charge rate.

To be more precise, it's a 40 amps limit, even at lower voltage (so for example at 208V which is a valid Level 2 voltage often present at industrial/business sites, you will only get 8.32kW from the EVSE, so 7.5kW effective charge rate.

But that's me.

I completely understand your observations about the virtues of the Taycan. I share many of those same thoughts. And after all, I still own a 2020 Taycan 4s, which Porsche has now downgraded the charging abilities of.

I will not try and persuade anyone else of the wisdom of my choice. Financial compensation, rather than a buyback, was not among the range of choices available to the arbitrator. Once Porsche said that they could not repair the vehicle and cure the defect (ie., that the vehicle could not perform to specifications) the arbitrator could only reject my claim or order a buyback.

The issue was not whether the charging rate of 9.6 kW is good enough (which appears to be your view) but rather should Porsche be able to sell a vehicle with one set of specs and leave the consumer with a lesser performing one. My value set says “no”.

I do not know whether Porsche has added me to the “no fly list”. I still own two of them—a 2020 Taycan 4s and a retro-mod ‘73 911. And the dealership where i have gone, which has sold me over 10 Porsches over the years, still seems happy to see me.

I have added a ‘25 Mercedes AMG SL63 Roadster to my driveway.

While I don't know the OP's usecase, I can share a real usecase my wife has encountered where 11kW charging allowed for some buffer charge in a Tesla Model S60D during winter driving. My wife used to drive about 150 miles in the morning to help out a family member, then got home, charged for a 2-3 hours, then drove kids to their activities, then got home again, charged for another 2-3 hours, the went to pick up the kids again. At that time I invested in an 11kW charger (the most that S60D would accept) as that provided my wife some buffer in the winter - without it, she'd arrive with very low SoC when it got freezing out, so any accident or delay along the way could result in her getting stuck. 4-6hrs of extra 20% charge speed gave her an extra buffer by end of day. This is also when I decided all our future cars should have higher speed on-board-chargers and invested in a triple 19.2kW setup in the garage. Even though my wife no longer has this demanding driving schedule, I still utilize the 19.2kW 1-4 times a year (usually also in the winter). Could I do without it, sure, I could switch cars, or take Lift or Uber, or borrow a car from a friend or family member, but hey, I bought a $200K Porsche so that I can drive a luxury vehicle and not my kid's Toyota Corolla because Porsche decided to lower the charge speed limit.

When it comes time for Porsche to refuse replacing my next OBC with 19.2kW charger, I will also fight for a buyback (heck, I'm willing to take it as a trade-in price towards a Cayenne EV which will come with 19.2kW charger). Alternative solutions that would work for me is a higher capacity battery swap (from J1.2, but not software limited) and replacement of my triple, load-balancing 19.2kW EVSE with triple, load balancing 19.2kW DC chargers in my garage. I've been thinking, once Porsche refuses, I can just buy a Cayenne EV Turbo, and then they can choose which one they want to buy back (buy back Taycan if unwilling to replace the 19.2kW OBC, buy back the Cayenne because I only bought it because Porsche initially refused to repair the Taycan).

As for buyback value, my state (Washington) has a very clear depreciation table which they use for tax purposes, so might as well use it for buyback price too.

Unfortunately Porsche can claim the 48A draw was a bug, which they eventually fixed for all cars from before May or 2023 and after whatever date they went back to 9.6kW spec. That would leave a small delivery time window of Taycans which could sue in a class action. I think in Canada that window may be a little longer, as Porsche has not updated the Canadian site till later.

Would you feel differently if you spec'd deviated stiching for additional $$ and your car was delivered without it. However, it was not removed from the price of the vehicle.
PAG has a habit of hiding defects by mandating change to customer behavior. They have limited: the EVSE charger's output, told us not to charge indoors, and don't charge past 80%-85%. There many cars riding around with defective batteries. PAG won't fix them until they present as failed.

They changed the charging on ALL Taycans (J1.1 with a silent software change) and new ones (J1.2) in summer 2025 (probably also with the same type of software change). On the specification of my new Taycans 2026 it is stated that the charging in AC is at 9.6KW max. It seems to have been done to merge the charging in KW with their charger sold with the car which is not able to do more than 9.6KW. If it was done for other reasons, they never published anyhow why they did it. This was done across all North Americas including Canada

I would not have got rid of my car for just that reason frankly but this was your choice obviously
