DC Fast Charging is always a disappointment.

Whats weird is, I end up seeing better recharge speeds or at least more consistency with the 150kWh when charging with EA. I don't know if it has something to do with the cooling of the cable or what, but generally speaking the 150s for me have been rock solid with EA, past that everyone else is better above the 150s.

on our recent trip to Utah and back we logged 2115 total miles and charged at 6 EA chargers and 4 ChargePoint chargers. With repeats going and coming at the same charger we charged a total of 13 times. Our charges were very consistent. We would start at 160 kWh on 350 kWh chargers and 140 on 150 kWh chargers. We would stay there for about 2 minutes and then go down to 110 kWh until around 60% SOC, then to 75 kWh till 80% SOC. After that around 35 kWh.
I thought the car could charge a bit quicker but realized this is just what the car is going to do. It probably added a few minutes to the charge over what a bigger capacity car would charge at, but you just accept the capabilities of the car. I didn’t mind the charging times and usually had a nice chat with another EV person or someone that would wander over and ask about the car.
while we had a couple of glitches at EA, they proved pretty reliable. All the ChargePoint chargers worked fine.

I had to stop in Lacy washington to charge at an EA. I tried multiple chargers and couldn't get faster than 35KW. I ended up getting enough to go to the next DCFC which was an EVGo, There I was able to get 130. EA is the worst...

Mid-30s on an EA station almost always means the temperature sensor in the cable has failed. Very common issue with their hardware.

In France last month this is what i got (chargingcurve) measured by the OBD adapter. This was charging from 22% - 60%. My GT can handle the peak quite a long time, but averages around 100 kW. This is a 300 kW charger.

I have had the "exact" same experience as AdamSNP.
"almost always get between 45-77. I few times I’ve gotten 120kW for the first minute but then it slows down significantly and it doesn’t matter" what Electrify America (EA) charger used.

I find really frustrating, as my Audi e-tron used to charge 150-160KW all the time using EA. Least when they worked. Now, I am lucky if I get a charger rate over 75KW on the MME. And at lest 40-50% of the time, I need to switch chargers. Because the first one is around 30KWH or doesn't work
I used to think it was the EA chargers. Maybe not. BtW, I travel between Gilbert, Arizona and Carlsbad, Ca fairly frequently. I typically use EA chargers at DateLand, Az, Yuma, Az, and El Centro, Ca..

To bad there is no insight if it's the EA charger or if the MME that is limiting the charge. Would also like the MME to tell me the KWs being delivered, rather than having to get our of the MME and check the EA display (assuming it works).

Fingers crossed that TESLA works well, I can stop using EA. And I can charge at least faster than 100 Kwh.

Not really that long. My SR battery usually charges between 60-80 kw at a steady state, and my 10-80% time is usually around 35-40 minutes.

Headed out for a relatively short 250 mile round trip from Boca Raton to Naples to have lunch with a friend.

left a bit early to charge at a FPL charging site close to the restaurant. I checked in the morning and all 4 chargers were working and PlugShare had a rating of about 9.3

about 30 minutes out I checked the FPL site and 2 chargers were out of commission but the other 2 were ok.

max 180kw chargers.

when I got there on women in a polestar was downloading the FPL app. I plugged into 1 station and maxed out at 64. I only charged for 20 minutes as I figured that was sufficient.

luckily all 4 chargers weren’t down. 1 large Tesla bank was in same vicinity and I can’t wait for our adapters to be available.

on another not the best I could do today was 3.1 both ways, temp was high 80’s and very humid, minimal wind. I never went above 70 mph.

At home in NY this summer I was able to make it to cape cod without charging (245 miles) getting 3.5. Maybe the humidity is a factor And I did drive a bit slower but not much.

I am glad the stations worked as I didn’t want to hear from my wife, Why did you buy this car! EVs are not for her.

The Mach E will not sustain 150-160 for more than about 3-4 minutes. It will then drop to 300A, which is around 110kW, for another 5-7 minutes before slowly going to about 80kW and then tanking at 80% SOC.

I think I've just been fortunate with my routes. Been on tons of drives between Ohio and NY and this has been my typical charging experience with my GTPE over the last year. Knocking on wood now.

You are right. Some EA stations here have stalls giving out 20-30kW instead of 150kW. I always had to move to another stall when that happened. That added about 5 minutes to the pit stop.

My ER AWD Premium peak rate was 157kW when I picked the right stall.

When you only get ~31kw, that's usually a cable cooling failure, or often just a failed temp sensor that fools the charger into thinking there's a cable cooling failure. Sometimes you can just switch to the other cable on the same charger and it works fine. That's worked a few times for me, although usually it's the whole charger. Worth trying anyway, especially if there's no other open chargers.

Mid-30s on an EA station almost always means the temperature sensor in the cable has failed. Very common issue with their hardware.

And with the brand new EA units, they will start out high (>200kw for my Rvian), then after a few minutes over heat the cable/connector and drop to 44kw. I have even seen them oscillate between the two values during a session. The Rivian tells you that the charger is limiting the power. GM has a feature in the Ultium vehicles for this too.

I have never seen an EVGO station do this. I have seen broken ones with error messages on the screen, but have never seen one output low power like EA does. EVGO is now using Delta as their supplier, they have a 350kw power shared CCS unit and a 100kw unit with CCS/Chademo/Tesla connectors. The 100kw unit is limited to 200A, and the MME gets 75kw on that one.

Thank you for the insight. It is good to know the reason.

How long does preconditioning last at 0 Fahrenheit? I preconditioned via the Ford nav and when I got to the charging station I had to wait over 1/2 hour for the only available charger. So I wasn’t sure if preconditioning helped or not but it would have used up some juice to do so.

Did a bunch of DCFC on my 22 SR battery this last week, best o saw was 108kw on a Charge point outside of Augusta Ga. Most of the time I pull mid to high 80s. And any time I get over 84kw from an EA I call it a win.

There is a Shell Recharge unit (pretty new < 1 year) in Fountain Inn that I have found to be good (better than the EA at Woodruff). Other than that I-85 is pretty weak. I live in Brevard, work in Charlotte and go to Columbia frequently so I have experienced your pain.

Lol, got stuck in Columbia Sunday, Showed up at the EA charger and the line was 5 deep of irate customers waiting on a stall. For my mental health I chose to just stay at the Hilton and lvl 2 it.

I thought I read somewhere that the new EA station tells you how much the car is requesting. Can you confirm?
