Taycan charges faster than Tesla V3 - but we all knew that.

We suspect the Taycan's primary reason for being able to charge so much more quickly is its 800-volt electrical architecture, which is twice the EV norm. The 350-kW Electrify America stations also operate at 800 volts, and the fact that the voltage is twice as high means that half the current is required to achieve a given rate of charge. We're interested to see if the Porsche's advantage erodes if instead using lesser, and far more common, 400-volt charging equipment, an experiment we plan to undertake at a later date.

Our charging session cost $43, which is more than five times the going rate in California for the amount of energy we consumed, and more than double what Supercharging costs.

However, you'll pay for it, as the Electrify America chargers are far more expensive to use.
If the "journalist" did the least bit of journalizing, they would have mentioned that the first 3 years of EA charging is free for Taycan owners.

in the journalist defense Porsche has done a **** poor job promoting that particular aspect of Taycan Ownership

I've encountered dealers that don't know about it.

Besides, in terms of marketing priorities, IMHOI, there is a lot about the Taycan that is a bit more important than whether a person buying a 150k+ car gets a couple hundred dollars of free charging.

personally I doubt 800 volts has a lot to do with it - rather if Porsche is _NOT_ charging to a "true" 100% SOC - and they are holding back - they can keep the charge rate relatively high all the way to the BMS (Battery Management Software's) consumer 100% - you have to taper the charge rate as you get closer to true 100% of the LiON cell - but if you don't charge the LiON cells to an actual 100% you can charge them at a higher rate until you decide to stop below the maximum…800v contributes, but BMS programming is probably the bigger factor here…

In fairness: It appears this Charging Speed article came, originally from Car and Driver (as they release info from their H2H testing, as with the consumption data) which I can see in the upper left hand corner of my browswer:

the required Ahrs for that battery system is halved. Since the Ahrs are halved, the time required to charge the battery is halved, assuming the same charging current.

The Taycan is the first production vehicle with a system voltage of 800 volts instead of the usual 400 volts for electric cars.
This enables consistent high performance, reduces the charging time and decreases the weight and installation space of the cabling.
