Retrofit 22KW charger

[mpaulus007]

Anyone knows if J1.2 allows for retrofitting 22KW charger? Using retrofit from J1.1?

unbelievable that this car is so slow on AC!!

IIRC, it used to be search results on the Tequipment website. I just performed the search for a j1.1, and it's no longer there as an option to purchase on the US site, but found it on the UK site: https://tequipment-finder.porsche.com/uk/J1/Taycan/&ac=product&pr=8C5870F2F0E23241C125885C002F6766

Best manner is to ask the dealership. 19.2/22kw onboard upgrade may be different on the j1.2 as Porsche repackaged AC-DC equipment. There was discussion on the forum that it may become available later (as an upgrade or as a new build option)

Use case is low in the USA, but I know in EU, there are a lot of 22kw AC chargers in parking garages.

In europe, porsche discontinued it.

All existing inventory is for warranty work. They advise against the "upgrade" at my dealer, even though it would be extra money for them. I may be wrong, but I believe the website doesn't list it anymore as a paid upgrade even for j1.1 - i can't find it.

The 22 kw onboard charger caused a lot of issues and therefore is no longer available.
I had twice problems to charge in AC and it came because I have this option on my j1.1
It’s a pity because it’s useful in a lot of public places in France.

Very much doubt it given the reliability issues besides there is no need these days for 22kW AC given the amount of DC out there.

I can not confirm any reliability issues with/ J1.1 22KW-charger.

My use-case: Arriving home late with low battery and need to be on the road early morning. Don't want to use an extra DC-stop.

2nd use-case: Hotels / Parking garages w/ 22KW charger. Top up before blocking fee kicks in.

I have the standard 11kW onboard AC charger and charge with my PMCC (with a max of 7.4kW supply). Charging from 25% to 85% overnight (ready by 08:30) is never an issue.

Some folk on the forum (search for it) have had 4 - 5 22kW replacements and most fewer than that. It was an outrageously expensive option (£1,800) hence why the take up was low for little advantage and certainly not needed for overnight home charging. Better to invest in a 3 phase electrical supply at home to max out the 11kW onboard unit which would obviously reduce overnight charging times by 50%.

22KW = 4 hours from 0-100%
11KW =8 hours from 0-100%
My night does not have 8 hours

I agree that they need to bring this option back for future Taycan's. I recall reading that there were some reliability issues with 19.2kW onboard charger on the J1.1 vehicles, but this is just technology and it's possible to fix and improve any part of the product.

I'd buy this upgrade in a heartbeat. I can't imagine the world sticking with 11kW forever.

Nor do you charge from 0% or likely need 100% every day.

for the J1 dealer install pricing was north of $5k including the "kit" from Porsche - not sure it's worth $5k for North America where there is very very very little 19.2/22 kW infrastructure to leverage.

it's worth considering as a $1800 factory option (but still pretty limited use).

Use case 1: Approximate math is using your standard 11kw speed, you can charge about 63 KWs in 8 hours, or about 75% of the battery. So even if you arrive empty at home at midnight, you'll have 75% by 8:00 am. You'll have a full charge from 0-100% in about 10 hours.

The 22kw use case is limited. Probably your use case 2 is more likely as you're looking for a "top off", but IMO that's what DCFCs are for. Even if you DCFC with no preconditioning, you'll still be charging at at least 3x - 7x the speeds of a 22kw AC charger.

I think the only use case for 22kw is probably for hotel valet or a car repair shop/dealership, whereby there's a lot of EVs to rotate and charge.

I initially thought that a 22kw at home's use case would be whereby you arrive at low SoC, midday and maybe you have just 2 hours at home, and you need 50% (about 40 kws) of charge/energy when you depart. But again, that's what DCFC is for.

I retrofitted the 22kW on my J1.1 - it did help a little but not as much as I has expected. I enquired on this option for my new J1.2 and was told "not available" as it was "not needed due to all the battery/powertrain improvements in the new model".

This is an incorrect comment from your dealer. A 19.2kW charger in your car is twice as fast as 9.6kW, assuming your EVSE supports 19.2kW charging. Those who have it notice the faster charging speed, and I'd get the upgrade if it were available.

My experience is that dealers still don't have much EV experience, so they say stuff....

My experience is: haste makes waste.
The 22kW AC-DC onboard charger (OBC) tends to run into issues, often preventing the car from charging properly.
Sometimes, after plugging in the charging gun, it throws a charging error (with a red warning) just 30 minutes later.
You go to bed thinking you'll wake up to a full battery… but surprise — it's barely even 5%.

I believe the main issue lies in the overheating of the OBC caused by high power output, which then forces the entire charging process to stop.
Every time an error message pops up, the charging gun and cable are noticeably hot to the touch — and that’s just with an 11kW load.

However, I’ve discovered that as long as I reduce the charging station’s output to below 10kW, say around 9kW, the charging process can be completed smoothly without any interruptions.
