Is the gt ever going to get a charging curve update?

[benk016]

I was hoping that eventually they would make a shift to the charge curve overall. More time at 150kw would make a huge difference.

My wife's Id4 claims 5 to 80 percent in 38 minutes. Only 135 kw charging

Id4 has a smaller battery so it doesn't take as long to charge.

This is true. It's only 6 kwh smaller.

I'm not gonna pretend I'm an engineer. Just seems crazy hers can go from 5 to 80% with 130 kwh max charging

I have a 6 extra kwh and can go from 10 to 80% in 40 minutes with 150 kwh max charging.


Granted the Porsche is still the fastest charging 300 kwh car so maybe vw has some tech too.

Either way none of it ultimately matters.

You're really only getting 75-100kw charging for the bulk of the charging on the MME. The 150kw will never go longer than 2 minutes, if you get that high at all.

I did get the extra 3 kWh added to the battery capacity at the same time the charging curve was improved, but the range didn't increase. From what some forum members have been told unofficially by Ford, the 3 kWh was added below 0%.

So while you could run your car down to let's say 7% instead of 10% on a trip, which gives you more range, the GOM didn't change. After my updates the GOM was still consistent with before the updates. Some people have seen driving history get reset, but that didn't appear to happen to me.

And to clarify, I did not receive any of these updates via OTA. The dealer did it with FDRS.

Here's one for the gtpe record charging to 100 pct. Highest miles so far at 298....all season tires are Michelin sport pilot a/s 5 which are very quiet and very good in snow and rain.

Looks like you drive your car like a little girl. So cute.

No offense intended!

I spin my tires whenever I get the chance. Which is whenever I am not with my wife. So my range is consistently 220 - 240. I am OK with that.

Hahahahahahahhaa truth. Drives like my grandma did slow. Prob drives 55 on highway ?. This is what 80 on highway and WOT stop light to stop light does ?‍?

GT OR GTPE was made for fun not Milage

Most of my miles are highway and I set my cruise at 80. Of course sometimes traffic interferes, but 80 definitely puts a hit in the old GOM.

I had my 9/21 build GTPE updated about a month ago with 21P22 and 22S41, took a ~830 mile road trip recently. Here are the charge curves for the three DCFC we did. The first one is the only where I took it over 80% (unfortunately that doesn't display well because of downsampling to 60s), was doing ~40kW where before it was ~10kW (IIRC). Blue line is SOC, orange is charge rate.

I’m really curious if anyone has done a comparison between 350kW and 150kW chargers? I can’t say for sure, but my hunch is that it has a higher average charge rate for 20-30 mins on the 150kW.

I've done those 350kw chargers. I will say it does technically get to 152 -155 kw for a bit but i don't think that's going to make that drastic of a change

The 350 is faster than the 150, as has been reported by others in this forum. The MME can exceed 150 kW on a 350, but it isn't for long. I would guess at best you save 5 minutes on a 10% to 80% charge.

i think the 10-80% is the same for 150kW vs 350kW charger, 41 mins. However, the profiles of the two charging sessions are different.

I’m wondering if the MME holds a higher average kW for 20+ mins on the 150 than the 350.

Bjorn talks about the revised charging curve on the MME using the GTPE as a test vehicle.

@DevSecOps, @benk016, @breeves002, @scoopman, maybe you guys would know better than most.

if the MME ER packs are only hitting 33-35C temps while charging, then it seems to me there’s a decent amount of room for increasing the charging power?

There's a lot of people more versed in battery chemistry than myself so they can feel free to correct me. The 95F temperature has been discussed by myself many times on this forum. Yes, the MME likes to keep temps at a max of 95F.

My understanding is that as temperatures increase above about 77F charging speed is actually reduced. So I assume you are asking why can't the MME let the pack get hotter? Based on my understanding that would actually slow things down. There's a crossroad where it's more beneficial to expend energy in cooling than increase temperatures at a slower rate. <-- wrong battery chemistry
