My first time charging in King of Prussia wasn't super fast, as detailed here.

Today I visited Cabela's in Hamburg, PA and hit the Allentown, PA Electrify America charger on the way home. My battery was pretty toasty (about 18*C) from some spirited highway driving on the way there. I arrived at EA with 24% SoC and found 7 of the 8 spots (4 "pumps") taken up by big construction trucks and guys with fluorescent blazers. Uh-oh, I asked if the chargers were working and they said probably, they were just doing roadwork nearby and parked their trucks there. Anyway, they were nice enough and offered to move but I was able to back into a spot adjacent to one of the 150kW chargers (there are also 350kW on site) so I just asked they not back up into me.

Unlike last time where one charger didn't work correctly, in this case I plugged in, entered the location in the EA app and heard whirring and clicking a short while later. I was very pleased to see a peak of 94kW that slowly tapered down:

2256

The amused road crew guys had lots of questions:

2257

I didn't really intend to charge to 100% but it was humming along nicely and I figured why not see how long it takes. Fully charged and ready to head home:

2258


The spot is a strip mall with a Chipotle's and a Giant grocery store and I was the only one charging. Other than the road crew, a friendly guy in a recent VERY BLUE Acura RDX pulled up and asked about the ID4, charging rates, stuff like that. I encouraged him to test drive one.

BTW, EA never took the $10 for escrow the first time I charged, but this time they did. I also got emailed a receipt, which didn't happen the first time.

Here's geeky details from the specific charger I used:

2259


I logged the session with VCDS and will upload a link to the spreadsheet later.

How long did it take to get there from Cabela's? The Allentown and KOP ones seem to be the only ones close to me so the free EA charging might mean very little to me. I feel like I'm pretty near the middle of them, one being northeast of me and the other, southeast.

Edit: Just looked it up. It is literally an hour ride to either one from my house...

I had the same issue.. On my first 5 DC charges it didnt hit the maximum charging curve. Im suspecting there is is a limit before full charging power gets unlocked. It could be the amount of driven miles or the amount you tried to fast charge. Beside that you start the charging with a high SoC%, you wont come near the charge potential this way, go to the lower 10's before charging next time ;)

There was a bit of road construction and it looks like it took 35 minutes to get from Cabela's to the EA charger. My battery heated up from 16*C to 19*C on the trip (it was still warm from my earlier drive TO Cabela's, I didn't spend much time in there, maybe 20 minutes.

That seems lower than I would have expected. Here is what Kyle had in his review:

View attachment 2260
I agree, I was hoping to see the same speeds Kyle saw, but if the starting temperature of my battery was lower than his, then the double whammy of slower possible charging speeds, plus some of the electricity getting used to heat the battery to optimal temp, would apply. The Porsche Taycan has a battery temperature display and since the ID.4 obviously knows its battery temperature, it would be nice to have that displayed as well. FYI, here are the charging stats I recorded, taken from photos of the EA charger at mostly 5% increments:

oooh..


If I've got Hex-Net and VCDS beta 21.2 how do I do that?
Make sure to update VCDS (currently Release 21.3) and update the firmware on your HEX-NET. Next, go into Select then under the Installed 2 tab you will find 8C Hybrid Battery. Click on Adv Meas Values and you will have a list of items in the popup dialog. You can choose up to 12 items but choosing less will result in faster logging. I selected these items (there are tons to choose from including individual cell voltages and temperatures):

IDE00021 Engine RPM
IDE00075 Vehicle speed
IDE01021 Current of H-V / hybrid battery
IDE06346 H-V battery voltage
IDE08217-MAS02985 maximum voltage for battery cells-Value
IDE08218-MAS02985 minimum voltage for battery cells-Value
MAS02199-MAS02985 Lowest measured temperature-Value
MAS02200-MAS02985 Highest measured temperature-Value

You can right click on the selection box and pick "Save selection to file" to save that list for future use, and retrieve it by picking "Load selection from file". Make sure to pick Group UDS Requests for faster logging. You can pick Graph to pull up a graph and gauges, and click on Log then Start to record the datalog. When you are done click Stop and then Done, Close:


Also it's a good idea to run channel maps to grab a snapshot of all possible values in a single module like 8C-Battery. I like to do that before and after each charging session. Interestingly the 8C Module showed "IDE01839,Battery charge level,29.600, %" when the display in the dash said 24% SoC and " IDE01839,Battery charge level,96.000, %" when the display in the dash said 100% SoC.

Thanks for your experiences (and I appreciate your Youtube videos too!) . Have you found any way to get the battery completely warmed up before charging? Mine went from 18.5*C to 30.0*C during this second session. If I could start it at 30*C that would be superb. I guess one way is to charge when it's about 90*F outside. :unsure: I live far enough away from fast chargers and have enough suspicion about them working that I'm not sure I would be comfortable getting down to 10% or less but maybe on a day when I have unlimited time and a lifeline to call.

Doesn't the car keep the batteries at a constant 77 degrees?

Not that I have found. 77*F would be 25*C. On my 58 mile, 52 mph avg, 1h7min, 2.4 mi/kWh minute drive to Cabelas yesterday in mid 40's weather, the temp got from 10*C to 17*C.

The battery just needs 2 things to hit that sweet 125kw charging curve..
1. 20℃/68℉ battery temp
and the most important thing
just a low SOC% <15%. thats it.

10℃/50℉ is also fine, but takes 5-10 %'s to hit 125kw, so thats not a problem at all if you start low enough

And to keep you not stressed. you have another 3% REAL charge under 0%. so worst case you have another 8 miles (at -5C/23F) you can drive the 0%. How warmer the climate the further you can drive that 0% ;)

With a Kona/Niro it just dies at 2/3% charge so thats not great.

Nope, BMS stops heating them up when it hits 10℃/50℉, after that it depends how fast you are driving how warm the batteries will be. It will even starts to cool them when it goes higher then 25C/77F

This morning I checked the Electrify America app that still showed nothing under charging history. I decided to check under payment history and under transaction history it shows the most recent $10 balance deposit and $0 transaction for charging. Going back to the charging history screen it now shows all three “sessions”, the first 1min, 1kWh fail at KoP, the successful but slow-ish 33kWh charge at KoP and this most recent 59kWh charge in Allentown.

I kind of like ChargePoint's app a little better - that one shows you an actual graph of power delivered as a function of time.

Ooh, that would be handy ... instead of me taking a couple dozen pictures of the charger to track its progress. :unsure:

The downside is that every ChargePoint DCFC that I have used is only 50kW. I think they have models that are more than this, but I have never encountered them.

Keep telling ya all. Start at a lower SoC (at least below 18%). Go to 5!% Yer gonna see those kW in those 125kW ranges advertised.

After 140 miles I went from 24% to 80% in 36min with peak of 104kw and total 41 delivered.

The car was ready before we had finished lunch and done family pit stop things.

Seemed great to me! App did take a few tries to connect and start session.

Also, the rain sensing windshield wipers are amazing! I've never had such a luxury.
