Dissapointing tacan DC charging

[ZenicaNC]

Personally I have (factory) InnoDrive but don't use it after initially playing with it.

No RAS on the wish list? While I am sure it's helping on highways, it's definitely useful when navigating parking lots of having to do tight turns, or u-turns.

Taycan is probably one of the most customizable cars you can get nowadays. I don't envy you having to wade through available inventory, as there are probably no two identically speced Taycans out there. The number of possible combinations outnumbers lifetime production numbers of all Porsches to-date and into the future. The more flexible you are on options, the more possible cars you will find. That said, it's probably a good time to buy a used Taycan - now that the new ones are no longer impossible to get, used prices came down almost to pre-pandemic levels (in terms of % depreciation).

Thanks for this info, now knowing that FOD is an available option, I will look to add InnoDrive and ALK via FOD. I'll probably also add PIRM and Power Steering Plus. Does anyone that has done this have any idea what the costs are for these FOD enhancements? At the end of the day, cost will probably not dissuade me but I am curious.

Check that your selected car doesn't already have PSP (Power Steering Plus - speed sensitive, power steering in general is of course standard) as I think it was standard for NA.

PIRM should be available at the Porsche Connect Store but wait until you have your car and Porsche Connect services established before you purchase anything. This will be tied to your VIN and Porsche Connect store will only list those items that are available for your specific vehicle. Your Porsche Connect contract should list all of your entitlements if your dealer can't advise in advance (they ought to be able to do this).

InnoDrive comes for free for the first month (or used to) and as long as you have Adaptive Cruise Control (ACC) then it should be available via FOD (note that it may not have the full factory fit functionality as others have mentioned - depends on whether all sensors were installed especially side ones used for kerbside parking), chances are it won't. No great shakes as InnoDrive probably isn't worth the investment but try it out. Suspect it will be around $90 / month or $900 one off payment.

I just checked, you're right, the 4S has the Power Steering Plus as a base option.

The car is out of state so I'm making plans now to go see it.

those were interesting graphs. How did you produce them? Presumably you have a device connected to the OBD port?

i’d be interested to see a graph like this which shows a cold battery in an average ambient temoerature. What I don’t understand, is how quickly the battery heats itself up. If it is not preheated what is the real penalty of using a cold battery? We fuss a lot in this forum about preheating, but if it only adds a few minutes until the battery warms itself up during charging, then who cares? Or does it stay cold/slow for a long time?

I can now bring some info on the influence of preheating or not on the charging speed and battery temperature.

For sure I can’t certify that the charging conditions, ie technical equipment, did not influence the charging speed. However I was the only one charging, so I could assume to a certain degree that these values depend on the car and not on the network.


I did two similar trips of 720 km/ 450 miles requiring 3 charging stops. In one I did not use the NAV (no preheating), in the other one I used it (preheating). In both trips the car stayed outside the day before, and T batt. was equal to the T outside (about 10° / 12°C).

I was driving on the highway, at a constant speed of about 130 km/h / 80 mph.


From start to 1st stop:

No preheating : heater was not active, and it took about 2hrs to raise from 11° to 24°. At that time, about 50 km / 30 mi from 1st charging stop, I switched from Range to Sport Plus, keeping the same average speed. As a result, the Heater fluid temp. … sharply decreased and T batt. stalled at 24° !
Driving at 240km/h / 150mph on the Nürburgring might show a different behavior, but I was on public highways…

Conclusions: first, it takes time (a lot…) to increase batt. temp and you won’t reach the desired temp. for fast charging (about 35°) before you have to stop. Second, switching to Sport Plus mode does not help.


Preheating: I have two sets of data here.
A: exact same trip. Battery has plenty of time to raise to 33°, heater starting about 1h before 1st charging stop.

B : in that one, 1st charging stop was quite close from start (about 50km / 30 mi). Batt. temp increased from 11° to 31° in 30mn (6 times faster than without preheating). Heater was working full speed, more than 10A. I don’t think it could deliver more.

Conclusion: you need at least 30mn to reach the best conditions for fast charging. That would double if you start from -10°, or divide by two if you start from 20°. That’s a rough estimation.



1st charging stop:

Unfortunately we have now another important parameter to consider: the initial SoC. Difficult to control in real life, so whatever follows may strongly depends on it. There was not much difference in the two trips however.

No preheating: starting from 20%, charging speed was about 150 kW until 55%, then went down to 100 kW until 80% (I stopped charging soon after). Decent average value overall : it took 26mn to go from 20 to 80%

Preheating: exact same trip (trip A - ie driving for more than 2hrs before charging – same outside temperature) but with preheating, this time charging with an initial SoC of 16% : charging curve was a bit better (up to 200 kW) at the beginning, but worse at the end (reaching 80%). It took 25mn from 20 to 80% …. 1 mn less than the no preheating trip

In trip B, where I started from a higher SoC(30%), charging speed went briefly to 200 kW, then slowing down to 150 and 100, similarly to the no preheating trip, at about the same SoC values.

Conclusion: the difference between the two is almost insignificant. In real life (I don’t live in ideal conditions like Porsche: With the Performance Battery, the charging time for 5 to 80 per cent SoC (state of charge) is also 22.5 minutes in ideal conditions at an 800-volt charging station, with a maximum charging capacity (peak) of up to 225 kW), for outside temperatures at or above 10C / 50F, it makes almost no difference if you preheat or not when your 1st charging stop is about 2hrs after departure.


More later on the subsequent stops …. and faster charging speeds
