Charging a Porsche Taycan @ 350 kw

[DP30]

Hi All,

I am right around the corner from one of Ionity 350KW and I am wondering if the Taycan is capable of fully utilising this or would it only go to a max under the 350kw figure?

The car can max at 270kw. However to achieve that it depends on your state of charge, battery temp and outside ambient temp

Thanks for this, so if I plugged it into a 350kw charger would it not work at all or would it work but only draw 270kw or depending on the conditions you mentioned above the max it could?

It will work, but just up to 270kW currently. Still really fast! If conditions are ideal, you should go from 5-80% in about 23 minutes.

the Taycan will draw the maximum amoutn of power appropriate for the circumstances up to a maximum of 270 kW

270 kW charging requires a number of “ideal” circumstances be present at the time of charging - not all of these are realistic - even in less than ideal circumstances the Taycan charges really really really fast - and even 150 kW gets you to 80 or 90% in about 30 minutes or less

one should not focus on the maximum charge rate, but rather the sustained average rate of charge, and the Taycan is the leading EV in production at this time...

on a recent california road trip I sustained an average charge rate of 130 kW during a 31 minute charging session at a 350 kW charger - this “slow” charge rate still provided me with a charge from 18% battery level to 88% battery in 31 minutes - one of the fastest charging sessions in my 7 years of EV experience...

I briefly obtained 254 kW charge rate, but by 40% battery I was down to 153 kW charge rate, but that rate held until nearly then end of the entire session - knowing what i know about EV and the LiON fast charging taper that is an impressive performance

if you are at a 350 kW charger you’ll be done in about 30 minutes - that’s what you need to know - anything else is details that honestly don’t matter in common usage scenarios.

Agreed, 270 is a bit theoretical. If I get 150-180 at Ionity it is still plenty fast enough. I actually prefer it to be slower and kinder on the battery. A coffee and a comfort break and it’s done anyway

here is that charging session…

the session was 67 kWh in 31 minutes - if you break that down…and I left with 88% battery - and my wife and I felt a bit rushed to get back to the vehicle to avoid idle fees…

67 / 31 = 2.16 kWh per min of charge
2.16 * 60 minutes = 129.6 kWh per hour of charge

for an average charge rate of 129.6 kW - rounded to 130 - now this rate was not continuous because the car started at charging at 254 kW, but ended up somewhere around 90 kW at the end of the session

however at the 31 minute mark I was at 88% battery and had more than enough charge to finish my trip home for the that day.

the simple fact of the matter is that at a 350 kW charger you can’t spend much more than 45 minutes because frankly the battery isn’t big enough to hold enough kWh for 350/250 kW charge rate for 45 minutes, and once the battery hits about 92-93% SOC the charge rate drops off to be very very slow to keep from damanging the LiON battery - so the time you spend to get that last 6-8% battery simply isn’t worth your time or cost…

a sustained 120-150 kW charge rate will get you to 90% SOC is about 30 minutes - and given that the last 10 % is sooo slow you’re better off to unplug and move along to the next charger rather than wait for that last 10%…

in the real world I don’t see much difference between 22 minutes and 30 minutes and both feel a bit rushed if you take a break, go to the rest room, and grab a snack or beverage while you’re charging....
