22kw upgrade concern appearing on porsche car configurator.

[tigerbalm]

After limiting my home charger to 6kW (26A), have no choice of taking 7.2kW (32A) when at a hotel. I'm sure infrequent charging at single phase 7.2 kW won't do any harm – but its still frustrating.

Folks like me that ordered the 22kW charger – did so because we value getting the fastest AC charge possible – regardless of phase or amps available.

All hotels where I charged were 3Phases. Perhaps this one is an exception? Or just load balancing across all these devices?

Anyways, I removed the option from my order because the note on the configurator recommends the standard charger in the first place. The suggestion to limit the maximum power appears as a "do it at your own risk" option to me (perhaps is just my english though).

And no mention of these recommendations on the Swedish configurator. Seems only the European English language configurators (UK and Ireland) have this text so far. Anybody else noticed it in a non-English language option description ?

No mention on the italian configurator. It's either lost in translation or translated with a different legal support. Btw, my dealer was strongly suggesting the 22k option (until I asked him to open the uk configurator...)

b) only have single phase (240V) so no need for the 22kW charger

The best use case for this charger is not home charging (7 KW overnight is enough even if you work 14hrs per day ) . It is decent charging speed at AC public spots (in case you do not find DC chargers, or you find them out of order, which is not unlikely). So, if you don't get the charger you double your AC charging time , if you get it, you run the risk mentioned in the configurator.

If I put 22kw charger in the next order,
can i set my mobile charger plus to 11kw with maximum 16amp ?

someone can test this and answer me.

that because I need to charge my Taycan with this spec

thank you

Or, while it's still under warranty, just charge as per spec that you paid for and let Porsche keep on changing out the chargers. Maybe at some point you will end up with a newer, corrected version of the charger (or perhaps software update which will keep it from dying). Sometimes a bunch of warranty bills from dealers is the only thing the corporate bean counters understand in order to get a new/fixed charger design approved (it needs to make FINANCIAL sense).

Read the manual for the device -Google it. You can set it to provide 100% current, 50% etc which will reduce the current to throttle back.

the mobile charger plus is the standard connector. you can select (with a button) either 100% power or 50%. But you need the mobile charger connect if you want the 22k charger, and the mcc can be set at any level you want.

Those of you in Ireland and the UK (where this new language has appeared in the configurator), may I suggest also reaching out to the manufacturers of your respective EVSE’s to enquire if they are aware of Taycan onboard 22kW charger failures in the wild under single phase level 2 charging at the full 22kW? The Porsche PMCC and PWCC units are manufactured by E-Systems MTG. In the UK, I believe Anderson’s beautiful EVSEs have been the Porsche UK recommended home install. While they might immediately redirect you to Porsche, they might also share their awareness of a known issue.

If this was a genuine concern I would expect Porsche to write to all current customers with the option installed and highlight it more prominently in the confuserator to give clearer guidance.

If I had the option I would play dumb and pretend I don't spend my life on the confuserator!

This is not the way to communicate something rather important.

My use case is home charging. I have 3 EVs and a time of use window of only 4 hours. Outside of the window my rate is 3x. On many days the only way for me to fully charge is with 19.2kW charging.

@andrewket Its not clear if the US market 19.2kW charger is one and the same part as the European 22kW charger. Although @daveo4EV has noted in past threads that the US 9.6kW onboard charger is likely the same part as it’s European equivalent due to observed ability to draw 11kW. I’ve not been able to find part number(s) that would answer the question.

(Electrical layperson alert) Also, it’s not clear to me if UK/Irish residential electrical conventions for a single phase circuit supporting 22kW are somehow different to how a US 4-conductor 100A circuit would be set up. Perhaps there is a difference that manifests more stress on the charger (e.g. more current on a single conductor that was inadequately designed with insufficient headroom for that specific use case).

It would be very unusual – to have such a circuit on single phase in Ireland/UK. The maximum the European AC chargers will charge on a single phase circuit regardless of circuit size is 32 Amps per phase or 7.2 kW.

To charge at a higher amount – you need three phase circuits. Then charging with three phases with the standard Taycan AC charger it will charge up to 11 kW. If you have the upgraded charger then you can charge up to 22kW – 3 x 7.2kW (per phase) = 22kW (approximately).

Sorry @tigerbalm - got my wires crossed! Acknowledging that the crux of the concern is 6kW vs 7.2kW on single phase with the 22kW Charger.

100%, the slower charge speed at home is easily worth it for on the move. In the unlikely event a slower home charge rate stops me setting off on a journey I’m, well, home. Being able to get a useful charge rate in remote places, broken DC sites or even when waiting for DC is more important to me.
