Potentially stupid 22kw charger question

[Dabz]

So clearly there are huge issues with the Taycan’s 22kw charger and I don’t particularly want to blow mine up.

I charge using the cable I got with the car often which means only getting 11kw from the 22kw capable chargers I usually use.

if I buy a cable capable of 22kw is that then putting the onboard dodgy charger at risk, or is that something different?

sorry for the newbie question - have had the car 3 years and only charged slower or far faster

Likely zero difference. 22kW cable hooked up to 11kW EVSE will actually heat up slightly less, but the OBC doesn't care. Porsche OBC just sucks. Both 22kW and 11kW die randomly, even when used at 7kW. There was a bulletin out a while back saying that if you have an EU car and charge on single phase AC, to limit it to 6kW (vs. the 7.3kW that the Taycan's OBC will attempt to use) to avoid a known issue that cause the OBC failure, but that applied to both 11kW and 22kW versions.

Both 11kW and 22kW have been reported by this forum members as dying and needing replacement. Porsche streamlined their spare parts supply by consolidating to a single OBC SKU. While some may theorize it was because 22kW dies more than 11kW, my suspicion is that they die just as often, but if you have replace so many of them, with most people only having 11kW OBC, it's cheaper for Porsche to replace every broken OBC with 11kW than to replace every broken OBC with 22kW - keeping only one SKU saves money in parts supply channels.

The 22kw onboard charger on your Taycan's option list?

The cable is a type2 and generally supports unto 22kw. Maybe the outlet is only 11kw, if this is at your home, then I assume you have had 3 phase installed?

The charger I'm using is definitely a 22kw one - we just had 4 of them installed near our other house on the Isle of Wight (where anything above 7kw is hard to come by!).

That said, rookie mistake having just checked my option list - I specced the 150kw DC-DC but there's no mention of 22kw so that may save me the cost of a new cable

So no 22kW AC onboard charger then?

Easy to check from the app if you don't have your original order form or spec. Go to My Porsche App, My Garage (top right hand corner), select your car, More details, Technical Details and there should then be a tile for 'Included Options'.

The DC booster option helps you get the most from a 400V EVSE (up to 150kW) as the car is natively 800v and ultra-rapid EVSEs (300kW+) are all 800v+.

The cable you got with the car is already the correct one for public AC charging - Mode 3, 32A and up to 22kW.

Logically, you should get 11kW from any public AC EVSE or at home (if you have a 3 phase electricity supply and your EVSE cable run (dedicated 32A supply from fuse box) and rating are all 32A and of course your EVSE can provide 11kW).

I think I have exchanged with you before on the OBC issues but just to ask, do you know how and when Porsche ratcheted back the charging capability of the Taycans with an 11 kw OBC?

My '20 Taycan will happily pull 11 kws (based upon information from my charger, and showing at a rate of about 10.5 kws in the car), and despite the quoted specs for my '25 Taycan 4s CT which says it should do the same, it will only pull 9.6 kws (based upon information from my charger, and showing at a rate of about 9.2-9.3 kws in the car).

J1.2 Taycans were the first, so in North America it’s model 2025 and later. Macan EV's were locked down to 9.6kW from the start (even though they also have 11kW OBC, which works at 11kW in 3-phase countries).

Interesting. So it is a software solution that was used. Presumably it would be reversible and could allow the charging at up to the advertised 11 kws?

More than likely yes. I don't own a J1.2 car, but for J1.1 NA cars you can enable a bunch of features only available in other countries (e.g. matrix headlights) using software re-coding.

dark market question: how can one access recoding assuming the dealer is not going to do it?

Yes, you'll need access to PIWIS tool to do it yourself.

I love the transparency and disclosure of Porsche in this:

• $100k Mid sized flagship SUV EV - max charge speed - 9.6 kW - even though it listed 11 kW for MONTHS
• $180k halo sports sedan EV - max charge speed 9.6 kW - oh and we'll nerf your older Taycan if you bring them in for service - the North American website has listed the incorrect stats for years
• $200k halo sports SUV EV - max charge speed "wired" 9.6 kW - max charge speed wireless 11 kw - optional 19.2 kW factory option with no word as to the rest of the EV fleet - we'll see how this plays out - none delivered to customers so far…
  • so my Cayenne will charge faster wirelessly than it can with a hardwired connection?
• $150k Hybrids (Cayenne/Panamera) - small batteries - max charge speed 11 kW - smallest batteries in the fleet get the fastest charging speeds…

Porsche’s disclosure on charging remains at 11kws for all of their BEVs. If you look at the MyPorsche app, in your “garage”, the 11 kws is there. if you look at the new and used inventory for sale of Taycans, Macans, etc., the spec disclosure even emphasizes home charging at 11 kws. i think they succeeded in changing their “configurator” to remove the reference to 11 kws. but thats it.
