I hope this isn't a parallel to what's happening here... In 2019 Tesla issued a software update that significantly reduced the DC charge rate for all 85 kWh packs. Without saying anything in the release notes. The truth only came out after a number of owners noticed reduced charge rate and other odd behaviors.

In my case, no: I’m at 2500 miles (new car as of 2/1/25) and typically DC Fast Charge once every week or two weeks. Once I’ve used up my 2-yr-or-1000kW-hr free EE DC FC, I’ll use my AC charger at home.

Thank you, that disqualifies my hypothesis as a possibility.

Go ahead and just use your L2 home charger for a week or two exclusively and then see if your initial charge rate at your local EA station will start at 195kWhr assuming the ambient temp isn’t cool and you’ve pre-conditioned the battery.

The question is not about the actual/initial charging rate in warm weather at low SOC. It's about the max DC charging rate shown in the charging meter.

No, I have about 7000 miles and DC fast charge no more often than once a week. I wonder if Ricerboi will read this and chime in about his max DC charge rate since he has high mileage and has done a "crap ton" of DC charging.

I was introduced to the Texan euphamism "shit ton" recently. I thought it was too crude to use, so opted for a more family friendly usage.

These terms are not casually interchangeable terms. They are an independent system of metrics that have a defined order of escalation. These are the relative sizes of magnitude, in order.

1. Ass-ton ≡butt-ton
2. Crap-ton
3. S*-ton
4. F*-ton

As a modifier, you can substitute "-load" for "-ton" to account for regional language differences.

I've used "shit ton" a shit ton my whole life and I'm from the midwest lol. But I will also sometimes let slip a "y'all" so maybe I have some Texan in me somewhere (being married to a Texan has probably increased my "y'all" usage). But I definitely do a lot of midwestern "ope" and "yeah no, no yeah"

No yeah, some of y'all do a shit ton of fast charging though.

Sorry for the late response. Ok so quick recap you guys know that I milked free EA DCFC the first 2 years/62k miles. Focusing on max DCFC charge rate, I would max out at 186-195kW+ during that time (usually charger limited. To be completely honest, the difference between 185kW and 195kW max for all of…the first 5-6 min of a charge is relatively negligible, but to answer your question, my cap number on the dash stayed at 195.

Fast forward where I’m 95% L2 charging and only DCFC for very few road trips, I charged at Baker EA last night and still saw the 195 number on dash and started the charge around 192kW.

The battery health/charging system is VERY temperamental. I will be at 89% SoH one day and 98% another. The range SEEMS to be better with L2 charging as the car probably uses less energy cooling the battery from DCFC.

You can see from my SoH chart what that dispersion looks like the last 30k miles.

Thanks ricerboi for the info. Wow, 62K miles in two years. Assuming you exclusively used EA, around 280 miles average range at 100% SOC, an average battery capacity of 105 kWh, and $0.56 per kWh (a before tax non-member price in my area), you milked EA for around $13,000!

Also, the max DC charging rate displayed in the DC charging meter doesn’t seem to be dependent on the battery age/health. My only guess is that it somehow dependent on a particular DC fast charger being used. However, I got the same 185 kW max using an EA and Tesla Supercharger - both were right next to each other. So, may be it’s dependent on a charging location.

Am I figuring this out wrong?

In my case, I’m limited to 2 years or 1,000 kWh of complimentary EA DC Fast Charging (whichever comes first), which I figure is roughly:

$0.56 $/kWhr * 1,000 kWhr = $560

Contract itemization highlighted below.

(Will find my iX contract line item and update, but it matches the i5 line item listed below… sorry about that &#128515
(Finally found / added the EA registration confirmation email with the details of the complimentary offer 😅- right one this time!)

[NomoTesla]

Yes, that is the new benefit. 1,000 kWh is equivalent to about 3,000 miles.

Yes but prior to MY25 you would get 2 years of free unlimited 30 minute charging sessions.
