I agree with this is "spirit" and I've been one of the biggest voices about this issue…
but I think we've just lost this one - Porsche has always had a wonky relationship with OBC max charge rate in North America and their lack of engagement and certainty on this issue I've always considered a...
it used to do 11 kW on single phase…it's only recently that North American Taycans have been neutered to 9.6 kW max.

not all Taycan's are bad - it's not a systemic problem - just some cookies out of the oven are bad - if you like the car just get a new cookie from the oven - the likely hood of two bad cookies is rare.
to demystify this stuff - the math is simple
the formula is:
watts = volts * amps
for simplicity sake we'll normalize voltage to 240 volts
that leads to the following table of "common" circuit breaker sizes - and "raw" watts/kW's capacity
Volts
Amps
Watts / (kWs)
240
30
7,200 (7.2)...
historically the Taycan shows the charge rate actually "hitting" the battery not the "raw" power coming from the EVSE - 8.8 kW is about right for a "raw" power feed of 9.6 kW…
this is inline with expected overhead/losses for converting AC/DC power to charge the battery and losses to run the...
yes you need a 48 amp EVSE on a 60 amp breaker in North American to provide 11 kW charge rate - however Porsche has been neutering their EV's to only support 9.6 kW max charge rate in North America…
the Macan EV is max 9.6 kW
Taycan gen-1 is 11 kW - or 9.6 kW depending on software updates...
Lucid owners are a hearty bunch - dealing with way way way more problems than Taycan owners…the software is an utter "sh*t show" - build quality highly variable, service is difficult and slow, and some problems still don't have fixes…
just _ONE_ example - a neighbor of mine owns a lucid air -...

a lot of people optimize for #2 - they end up driving a crappy car because it doesn't ever need to be fixed - never mind that it's a crappy car - I...
that's the problem with this entire thread - the assertion that there is a viable alternative to the Taycan…there simply isn't - there are however acceptable compromise choices, but they are all a compromise - no question…
there is no alternative.
my guess/speculation has to do with MTBF "hours" on the onboard charger (OBC) and other ECU's that are kept awake/running during the charging process…
if you take their battery warranty of 100,000 miles - at 3 miles/kwh that's ~33,000 kWh's to drive 100,000 miles
33,000 kwh @ 1.44 kW charge...
