Only getting 100kw/hr charge rate at EA Stations

[ForeverWild]

I’m new to Porsche Taycan. Been using Electrify America 350 KW rapid chargers and only getting about 100-130 KW/hr rate. I’ve tried several stations at different locations. Same result. I’ve also tried the lower rated 150kw/hr stations with same 100-130 KW/Hr result. Is there a setting in my car I have to adjust ?

What % do you have when you start charging? Those high charging speeds are between 10-60%, outside that range it goes down to 100-130 like u get

Do you use PCM navigation to the fast charger, so the battery preconditions?

Common if you do not preheat the battery to the right temp, SoC is too high, and if you have Battery Friendly setting ON.

Therefore, I would try to make the charging station as destination from the Nav -> Charging tab and observe your battery heat up to at least 95F when you arrive. I am of a strong opinion to NOT EVER use Battery Friendly in OFF setting as it cooks the battery for ZERO benefit. However, for your test, keep it OFF to see if you can get your speed close to 270kW with 296kW not uncommon when everything is working properly from the car and charger side.

You’re charging consistently that fast at EA stations?
If they’re in the northeast, lmk which ones so that I can use them.

It is common for me to be able to charge faster at 150 than 350..plus 350 seem to be out of order more...don't be afraid of using the 150! I even see the 150 hit 170 + sometimes.

That brings up a good point, why does EA derate the chargers in the NE more than the rest of the US?
I've only ever seen triple digits for the first few minutes, then it's down to around 85 kW, and that's with preconditioning the battery.

If you are getting 100-130 on 150KW and 350KW chargers, then I'd suspect that the car is limiting the charge rate.

Try this as a test:
1) Deplete the battery so that you arrive at a charger at under say 25% SOC. The highest charge rate happens when the battery is at a relatively low state of charge. Google "Taycan charge curve" for more info.
2) Turn off battery care mode.
3) WIth preconditioning on, use the PCM to navigate to a known-good EA 350KW charger that's around 30 minutes away, and/or lead-foot it before getting there - anything to increase the battery temperature to 90F or so. Battery temp in the Gen1 strongly influences the maximum charge rate.
4) If you can, arriving at the charger, follow someone who saw a high charge rate - to verify that the particular charger is working well - and of course try to pick a charger that is not power sharing at the time.

While you certainly won't be able to to do the above every time you charge, and you would not want to, those conditions will give you a decent idea of your maximum charge rate, which should be above 270KW if only for a few minutes, and above 200KW for quite some time. If you are STILL getting only 130KW, then perhaps there is something wrong with the car.

also to add, it takes a while to preheat the battery. It depends on the ambient temperatures and whether your car has been in operations. From a cold battery at about 50 degrees, it can take at least 30-45 minutes to preheat. Best way to monitor is to have the battery temperature gauge toggled in the 3rd instrument pipe. As others said, ideal SoC needs to be around 10%-20% to hit 250kw+.

Lastly, I wouldn't get too caught up on hitting 270kw. It's cool to see it, but you'll notice the charge session speed ramps up and then slows down based on SoC and temperature. But for the j1.1. the AVERAGE speed for a session in the 10%-80% should be 200kw.

Also helpful is setting the drive mode to Sport Plus (or at least just the powertrain to Sport Plus in Individual model).

How long does it take to precondition the battery. I’m starting at about 40% SOC.

yes. I’m in Arizona. What do you average ?

I thought in doing so, it's to prevent the battery from overheating? Sport Plus turns on the battery fans

I ask and answer: Why won't my Taycan Charge as fast as I want it to?

Time to precondition depends on the starting temp.
But recently on a day with air temps in 40s F, I started off by navigating to a station ~27 miles away.
Within about 12 miles of the station, the battery temp started climbing noticeable, and hit 81F by the time I reached the station.
Otherwise I probably would have stayed in the low 50s F.

As for typical speeds, I have yet to visit an EA station with the new Gen 3 stations.
But in our household's prior EA experience, arriving at an EA station with an available working charging that gets anywhere in the low triple digits is a major victory.
(Ironically, the fastest speed we've ever received at EA has in the low 180s at an ostensible 150kW unit with my wife's 400v i4. Those 150 labels are uniformly applied to a wide variety of chargers, so the 150 units are often faster than far less reliable 350 units.)

Generally, the further north you go in New England, the worse the chargers (excepting Tesla of course).
For example, that preconditioning experiments of sorts was to check out a new station built with $2.46 million of funding from CFI (sibling of NEVI).
The station comprises four L2 plus and four CCS1 plugs at two chargers, each capable if unshared of 640kW. (Yes, 640, not 64.)
I was at 49% SoC so should have been about 225kW.
Instead, the charger quickly ramped up to ~110kW, then dropped below 100kW, then never got back into the triple digits (let alone anywhere even close to 225kW).

That charger is the same brand (Autel) as the new installations at Massachusetts Turnpike rest area plazas that when shared are reported to deliver only in the 20s kW.

It could also be due to the grid, with the power supplier employing peak shaving to reduce peak load or demand, which in turn lowers the charging rate. To compensate, fast chargers have backup battery systems and, in some cases, ancillary solar panels (though not all do). These help offset the reduced grid power, allowing you to still get a decent kWh output. So, depending on the time of day and overall demand, this could be why you’re seeing slower charging.

^ Does anyone in the U.S have battery backup at DCFC stations besides Tesla? As for solar to provide a megawatt of backup power, I found an estimate online of six to eight acres of total size for a solar farm including equipment etc.
