How big a deal is it?

[Midlifecrisis]

I am considering buying a Taycan (test drive next week) and have been doing a bit of research on the forum. The biggest concern I found was buried in the posts from a few months ago. It seems that (in common with all EVs - apparently) that as the level of charge drops below 50% the available power drops as well. If charging to 85% then you only get 35% of battery at full power before it drops. As far as I could tell it falls as the voltage from the battery drops as the charge is depleted.
So how big a deal is it? Do you notice it? How much slower is the 4S or the Turbo at 30% charge? Can you no longer reliably overtake things?
This is an aspect of EVs that I had not heard about but it seems that it probably applies to all EVs.
I would be interested to hear the real world view.
Thanks.

I don’t notice anything in day to day driving.

the only time a low SOC would have "visible" impact is if you were doing launches at a low SOC, driving shouldn't see any impacts. when you reach a very low SOC it would be wise to slow it down in order to reach a charger.

I have had my Taycan for a year and have never noticed a performance drop at less than 50% SOC. If there is a drop, I haven't noticed.

I agree with others - never observed any drop in performance (has it down to 5% on one occasion)

There are gray bars at the outer ring of the speedometer indicating how much power is available. The Taycan RWD and Taycan 4S are less effected by battery condition, but both battery temperature and SoC affect maximum performance, where ideal temperature is around 86F (30C).

The reason why the 'less powerful' models are less effected is because the motor's maximum consumption is lower, so the batteries are more freely available to be able to supply 100% of those model's power requests (versus say a Turbo or Turbo S model who need more juice). This is also another reason why the 'performance battery' upgrade is more useful than just the 30 extra miles of extra range, as it improves power availability.

this is the reason the Taycan is different than 'other EV cars' and why a 2min comparison video does not do it justice in the 'real world'. There are many videos out there (some may be nice and post then here) were the Taycan competes against the Tesla and after about 5-launches, the Tesla will never be able to compete for the reason of your OP. However, until about 5% (I saw one video where it was below 5% and launch control was slower), Taycan's performance is repeatable, time and time again.
I only think it limits it below 5% to ensure that you have juice to get to a charger. Other than that, you have the other 95% to use with continuous power and performance and not worry about a vehicle that only performs 'as tested' when it is fully charged or over 80%. This is one of its claim to fame, reliable, repeatable and consistent from beginning to end.
Hopefully as you dig in more you will realize that the Taycan is 'not like other EV's' and despite (perhaps) not being the king of the hill on 0-60, it is king of the hill with repeatability and drivability and all-around daily performance.....just like all other Porsche's.

My Turbo S is faster than 99.9% of vehicles on the road at 100% state of charge and faster than 99.8% of vehicles on the road at 20% state of charge.

In all seriousness I haven’t noticed a difference.

Turbo S here as well and same experience. I pay attention to the gray bar and it always shows full power available, even below 50% charge. I sometimes press the go pedal hard just to make sure. ?

My understanding is the battery bank is built around lithium cells and the voltage varies from 3.1 (0%) to 4.2 (100% charge) from each cell. For information the average voltage per cell is 3.7v

I believe this is a 198S2P configuration. 198 cells in series with 2 banks in parallel.

198 Cells multiply by 4.2 is around 830 Volts at full charge, Once the battery depletes it can go down to 613 Volts. It is about 200 Volts less than a full charge. To get the same power the number of Amps needs to increase if the voltage goes down.

I believe in normal condition the system adjusts the AMP delivered but you should see the a drastic difference in launch control mode. Actually Carwow did some test with a Turbo (or turbo S) that was at 20% and the 0 - 60 was over 4 S if I recall properly.



For information the non performance battery is a 168S2P configuration which is only 705 Volt at full charge and this is why the performance is lower than the big battery.

There is a noticable power drop at low SOC and/or low battery temp. It is much more obvious in winter, if the battery temperature goes down below 4C.

But even with the reduced power output, it remains nimble enough to easily overtake and accelerate.

So in my turbo below 30% state of charge it feels like the 620hp becomes 480hp. Still rapido

IMHO, “the biggest” deal is that one can’t buy Taycan at all….i mean, delivery dates are postoponed, or orders even being cancelled…

I don't speak Slovenian, but I see 2 Porsche approved used Taycans available: https://finder.porsche.com/si/sl_SI...eFilterType=PREOWNED_PORSCHEAPPROVED,PREOWNED Maybe that's an option ? It was for me in the Netherlands.

Never noticed it, so there is no issue here - maybe in very cold winter days. My 4S+ is always fast enough in every road situation at any SoC.

When you are at the very last few miles of range you most likely treat the go pedal like a raw egg, so that you reach your charger...
