Hello MME owners,

Brief review from our roadtrip (AWD + big HV pack) and some 'good to knows'.
Left Orange County CA Sunday morning 12/19. Relied on the Ford App to schedule chargers (Electrify America), also downloaded the ABRP app (very useful even in 'free' format) and the Electrify America app. Drove about 5 over the speed limit the whole way (this is 85 mph in Texas LOL).
Used just under 500kWh on Electrify America super chargers (12 stops). Arrived Wednesday morning 12/22 with the big U-Haul behind us.

1. Our MME uses way more electricity that the planned trip from Ford. Very scary first stop in El Centro. We continued to push forward even though the vehicle started stating, "turn around you won't make it". We did reach El Centro with more than 10% charge left. Not a comfortable feeling.

LEARNING | Do not rely on the Ford app to advise you where and how much to charge. Reality will always be different than the theoretical distance/State of Charge algorithm. Going uphill towards El Centro threw the algorithm in trouble as on the other side of the mountains you are super efficient and actually gain some charge.

2. Stopping every 110-150 miles is actually quite nice. 30 minutes charge, kids can run around for a bit and we get a coffee. Doing 600 miles a day never felt so relaxed.

LEARNING | Relax and always keep the charger running to 80% SoC. The drop off in charging speed starts to kick in at 75% SoC and halves again at 80%.
Best we saw was 124kW charging. At 75% it is generally still around 90kW and at 80% its drops to about 38kW.

3. Electrify America was really the only choice on this trip. We are definitely in a DCDC charger desert between CA and TX. Major differences in charge speed even in the same charging plaza.

LEARNING | The charging poles are generally 150kW or 350kW with 2 connectors. Check the initial chargeing speed. If less than 120kW+, try another connector or charging pole. We have seen between 35kW an 124kW on the same charging plaza between different poles. Even on the same pole, there can be a substantial difference between the left and the right cable. Check and if you don't like the number, change. And yes, all these charging cables are basically 1 to 2 feet too short.

4. We used the Ford Blue Oval Charge Network to take benefit of the free 250kW charging you get when you purchase your MME. Worked flawless with Electrify America. Just drive up, plug in (have patience), it will find the vehicle info eventually and it starts charging. You get a message on your app when you've reached 80% SoC and how many kW was deducted from your balance. Once you are out, it will start charging at the regular non-member rates from Electrify America.

LEARNING | Use the freebies from Ford. Immediately cancel your Ford Blue Oval Charge Network as it offers zero benefits to you as a consumer. You pay regular non-member rates. The features like warnings about 80% charge etc. are all available in the apps from every charge provider (Electrify America, ChargePoint, EVGO, Blink etc.). Buy a membership from a charge provider that you'll use mostly. We're stuck with Electrify America in San Antonio TX, and for $4 per month we get a 25% discount on the per kW rate. Good deal as we always charge at public places.

Hope that was usefull.

Nice write up!

Sounds like you've got the new charging profile on your 4X. I'm curious about the time it takes to go from 10% to 80% and if it's any quicker on your 4X vs your original CA Route 1?

Were you towing a trailer? How heavy? Towing really decreases range.

our first MME was a California 1. The OBCM is basically the same so there was no difference we saw between our old MME and the new one we just got with AWD and the big HV pack. The pack between these models is the same.

the time from 10% to 80% is mainly charger dependent plus other factors like ambient and HV pack temperature. We saw 40+ minutes charging for that scenario. Had to change charging poles once though as they also differ in how fast they taper down. Was not bad at all with a good charge pole.

no towing !! Impossible to charge between chargers as the range degradation is insane. There are simply not enough DCDC chargers along the I10 to accommodate for a 50%+ range degradation. We already lost 30 miles between the California 1 version and the current AWD version we have now. Plus the AWD is less efficient per mile driving (drives nicer though). Same as a roof rack. Thule has some decent aero options but I’d stay away from it. Eats up too much range.

I wouldn‘t cancel the Blue Oval network. I’ve made several road trips and used the EA Pass+ membership activated for the trip and deactivated when done. when I need to just make a short trip where I know I might charge just once or twice, I just use P&C. It’s easy and fast.

Ok, so it sounds like you're saying the 10% - 80% time on the new profile is the same as the old one. It's only the 80-90% part of the profile that has improved.

Thanks for the write up, very helpful. Could you share which EA stations you stopped at? I’ll be driving somewhat regularly between SoCal and San Antonio so I’m curious how the roadtrips would look like. I’m pretty bummed that SA only has one EA station and it’s on the far side of the city from where I usually stay at… better than nothing I suppose.

I think that's correct. I recently got the 21p22 update and the 0%-80% curve seems about the same (hopefully that will be improved, though :)). The higher charging speed goes beyond 90%. I got 40+ kW north of 80%, and I've seen others get higher charging speeds as high as 95%...I believe the 'cliff' is now around 95%, and the charging speed between 80% - 95% tapers from the low 40s to around 30 kW.

Hello roz. Sorry for the late response. Been busy building a new startup in Texas :). We charged at the following Electrify America stations, always up to 80% SOC max.

- left Lake Forest CA at 100% SOC
- charged at El Centro CA for an additional 69% SOC, 172 miles, 82 minutes (changed poles)
- charged at Dateland, AZ for an additional 44% SOC, 117 miles, 25 minutes
- charged at Casa Grande, AZ for an additional 51%, 132 miles, 30 minutes
- charged at Benson, AZ for an additional 55%, 141 miles, 38 minutes
- charged at Lordsburg, NM for an additional 35%, 101 miles, 27 minutes (changed poles)
- charged at Deming, NM for an additional 22%, 55 miles, 22 minutes (changed poles)
- charged at El Paso, TX for an additional 38%, 102 miles, 27 minutes
- charged at Van Horn, TX for an additional 32%, 86 miles, 19 minutes
- charged at Fort Stockton, TX for an additional 33%, 92 miles,. 19 minutes
- charged at Ozona, TX for an additional 46%, 128 miles, 30 minutes
- charged at Junction, TX for an additional 40%, 118 miles, 26 minutes

Arrived San Antonio with 34% SOC

Hello all, see the same. It tapers down to 40-43kW from 80% to 93% on my MME, then down to 26kW. Again lots of environmental parameters will affect this. Ambient temp., HV pack temp., charge pole itself. No 'one size fits all', every charge experience will be different. Updated the charging stops on this trip with % SOC added, miles added and time to charge and you already see big differences between speed of charge between charging stops.

Thanks, hope the startup is going well so far :) this is super helpful, did you encounter any EA stations that were completely down?

Hello roz. All stations had at least a few fully functional poles. All good there.

Thanks Jasmin, for a very nice writeup. And it's partic helpful to my wife and I (we're older) as we're close to ordering a MME. I'm all for stopping every 110-150 miles, for lots of reasons. :) It sounds like EA chargers were dominant on your trip. Can you comment on whether these were associated with restaurants, walmarts, hotels, etc? In other words, what did you do (besides let your kids blow off some steam) during charging breaks? You mention coffee, but were these thermos breaks, or individual purchases at shops like the Blessed St. Arbucks?

I did a similar trip, north Orange County instead of south. Went out on the 10 instead of 8. All the way to Fort Worth, it was EA. Mirrored the list above from Casa Grande to San Antonio for most of the return trip. Most were Walmart's, but Van Horn, Ozona and Junction were all hotel parking lots. Actually stayed at Junction, nice to plug-in and relax in the room while it crept to 100%.

I had my 80+ year old mother and at each stop she needed to use the facilities. The only places she didn't were the shopping mall ones in Arizona. Pretty much taking her in, waiting and heading back used up most of the charge time. Got snacks at the service stations, I'd often find a drive-through near the charger and get some food to eat in the car while charging for the lunch time stop. Lean the seat back, relax and listen to the radio.
