@W8MM I expect it will work just fine - with no changes.

Mike, did you Panamera came with the 675B or 675C version of the Porsche charger? 675B is the 16A one and it's the same one as the one that came with the 918.

Porsche switched to shipping e-Hyrbid models with the 675C charger, that one is a 40A charger. My Panamera Turbo S came with the 675C. Porsche uses that in their Taycan press photos and also in their display cars.

They also have a newer version of the 40A charger, in a smaller plastic housing and without the LCD screen, my e-Tron came with the Audi branded one. But this new charger is actually bugged and can't go full speed.

The question will be whether Porsche will ship their car with the old style charger or fix the bugs and ship with the new style VAG corporate charger.

@Whoopsy thanks for this 1st hand porsche/audi charger info - it's great!

question is 675B charge rate 16 amps (20 amp breaker) - or is it's breaker size 16 amps (meaning a charge rate of 12 amps)?

16 amps * 240 volts = 3.84 kW
12 amps * 240 volts = 2.88 kW

full charge time for Taycan would then be with a 675B charger would therefore be (depending on answer above)

93.4 kWh / 3.84 = 24.32 hours (26 hours likely)
93.4 kWh / 2.88 = 32.43 hours (35 hours likely)

a daily drive of 60 miles = 20 kWh consumed
20 kWh / 3.84 = 5.2 hours (6 hours)
20 kWh / 2.88 = 6.9 hours (7 1/2 hours)

I think we can all see why Porsche is including 675C/40 amp charges for 9.6 kW - it's the only charge with a decent enough charge rate to keep full battery change times reasonable.

Sorry my mistake, I had mixed up a little bit of the specs.

Here is a pic of the 675C, it's is actually rated for 30A.


This is the 675B 16A charger.

The newest charger is 40A and is actually called the 675AB



Same charger in Audi guise.

ok 30 amp Charger would require a 40 amp breaker (actually slightly less but 40 is the closest and will more than cover the 20% continuous load requirement)

240 * 30 = 7.2 kW

93.4 / 7.2 = 12.97 - (14 hours to fully charge a Taycan with a 30 amp charger on a 40 amp breaker).

Being pedantic as I am, it is a misnomer to call them "chargers". They are technically called Electric Vehicle Service Equipment (EVSEs). The real charger, for Level 1 and Level 2 AC charging, is a box buried somewhere inside the car. The charger converts AC to high voltage DC at amperage levels that are deemed safe by the engineers who designed the battery pack. A EVSE is basically a fancy extension cord. It does some checks (e.g., ground faults and such) for safety, tells the car what the maximum amperage it can support is, and turns the power on and off as the charger in the car desires. Some manufacturers call the portable EVSE they supply a "charge cord".

Level 3 DC fast charging is different. The charging equipment is in a huge box somewhere on-site - typically fed here in U.S. with a 480V 3-phase feed. The charger box buried in the car is bypassed. The car must then communicate with the external charger in real-time its needs for voltage and current to properly charge the battery pack in a safe manner.
