Taycan Charging / EA 150kw vs 350kw

[snydema1]

so firstly - I'll apologize in advance if this question has been beaten to death - but I'm having trouble figuring something out.

I bought a 2022 Taycan (regular) about a year ago. not our first Porsche, but our first Taycan.

we've been pretty happy with it so far. it's my wife's car - and she really never drives more than 200 miles on a trip - so some 240v/50amp charging at home has worked out well so far.

we bought the car off the lot - as far as charging / battery tech - I see:

Performance Battery Plus (93.4kWh)
and
19.2kW On-Board Charger
and
On-Board 150kW/400V DC Charger

we're thinking of taking her car on a long trip in a few months. I did integrate Apple Maps with the car - which has been working great.

when plotting out my trip - I see that there were some filters for EA charging stations that did 350Kw, 150Kw, etc.

as I'll be stopping to kind of top off the battery while driving - and am fine with spending 20-25 minutes per stop - would it make a significant difference based on the car / my options to only stop at 350kw stations?

or in my situation - would the 150kw work great, and just be slightly slower than the 350kw?

The difference between charging from say 20% to 80% at 150 kW compared with 350 kW will be like ordering and drinking a second coffee! Time is about 7 to 8 minutes extra if even that. All comparisons with a properly preheated battery.

At least here in Europe and assuming the charging stations deliver the power stated. In North America there seems to be a lot varied experience on 350 kW chargers.

thanks @Scandinavian - that's what I was reading - but not all of the reading I did pointed to the same conclusion - and then there were lots of conditions based on the equipment in the car.

huge thanks for responding - and giving me some great real world advice.

so I think I'll likely filter by 150kw or better - and if I happen to come across 350kw, great - and if not - I'll stop at the required stations even if they're 150kw.

thanks again!

150 will be fine - maximum difference to 95% is about 8 minutes - both get the car to 85% in 25 min or less

If you use a 400 volt 150 kW charger they should give you about 130 - 140 kW in my experience! And you have that installed so you should be fine.

In case you haven't seen this thread: I ask and answer: Why won't my Taycan Charge as fast as I want it to?

Be forewarned that many EA chargers, even if not broken outright , are charging at nowhere near their stated ratings.
Right now on the East Coast, many EA stations are actually running at max 50kW!

Same here in Houston for months, until just a couple of weeks ago. This week, I was getting 168 kW from a 150 kW station. Hopefully, it'll stay this way for a while.

I did integrate Apple Maps with the car - which has been working great.

If you use Apple Maps on your trip instead of the built in nav, then the battery will not precondition and charging will be slow. Use the built in Porsche nav with charging planner for your trip.

ah, that’s a great point @Hirschaj - ty! Great info before I start taking some longer trips.

i really don’t like (kind of hate) the built in nav app.

I’ll have to give it a go and check things out. Luckily we’re usually not in a rush so if the first couple of charges take a bit longer it won’t be the end of the world.

Much appreciated!

My experience with "not navigaing" to a DCFC in the list using the built in Nav is the charging speed on a 350kW charger can be rather dismal, as mentioned. Thus the time difference between a 350kW charger and 150kW charger may not be much. I have seen up to 170kW using a 150kW charger if the charger can supply 425 amps.

If you use the Battery Saving option in the charging menu there may not be any difference at all.

In regards to your 19.2kW On-Board Charger...That (as I understand it) will only help you when charging AC or at home (or other level 2 chargers running up to 100A fuses but most run at 50, so won't help).

Most level 2 chargers at home run a 50A fuse in their box (40A to you) (Tesla Gen 3 can get 48A off a 60A installed) and deliver up to about 9.4kW charge. (Porsche's Mobile Charger Connect demands you detune their 40A to 20A unapologetically...so don't buy/use this!) If you install a 100A fuse in your panel then make sure you get a charger box that can handle it and then you should be able to take advantage of your 19.2kW On-Board Charger. If you don't have this on board charger you're capped at 40A (9.6kW).

Before doing all this, make sure your panel has capacity to add and distribute 100A based on the total load it is already carrying. (If you are already using 250A on a 300A box...you can't just pop in a 100A fuse without likely problems)

Note: I am not an electrician and may stand corrected.

^ In addition to all that, you need to buy a different type of charger to take advantage of the 19.2 kW option at home.

question: is it not possible to use both? input destination in both PMC and Apple Maps? does one cancel the other out? i haven't tried it, curious if it's possible, so theoretically the car will precondition (if you select the same charger in both apps) the battery and you can navigate via apple maps.. ?

You’ll be lucky if you get 100kWh at either of them, so I wouldn’t worry about seeking out 350s.
