So so so many power bars

[Kevin P]

I get the reduced power bars at cold start (not as many as in your picture), but they go away after a few minutes. At approaching ~80 I will see three or four bars, but they go away almost immediately when I slow down (unless the battery is at low SOC, like 30% or below). No bars at all under perhaps 70mph until battery charge drops off. I don't think I have ever seen as many bars as in your picture, and certainly not for very long if so. I would guess it would run something like 5 seconds 0-60 when I see a restricted power issue on cold start. Its still pretty quick. Similar to a Premium AWDX.

Somewhat related... For the first time I got the car into a power-reduced mode due to aggressive driving a couple of days ago. I did repeated full-throttle runs (probably 6) from 20-60+ while showing the car off for a friend. After the last one, I saw three or four bars, but they disappeared in about 20 seconds or so. I don't believe I have ever triggered that in my normal driving.

All of the above are in ~40-60 degree weather. Hasn't been really warm here since I owned the car.

My general sense is that Ford relies on the pack to moderate it’s temps as passively as possible. Ie: there is no proactive management of temps to ensure sustained peak performance (with the exception of Unbridled extend mode).

Instead they use the current in/out algorithm that is A: software and B: by all accounts extremely conservative.

I did a 17% to 81% DCFC charge at EA this morning and saw a significant number of bars for about 5 minutes.

GTs have a tiny "power bar" in the lower left corner (the fact that it's tiny and in the lower left corner is another issue) and when the GT lowers the power output of the motors due to being too hot or you going too fast or you having recently fast charged it grays out part of the bar which if you look closely you can see on the right side of the power bar. The green circled part is where it shows if you're regenning, the blue part is available power, the red part shows how much power isn't available.

It really irks me that they made it so tiny. It's the equivalent of putting a 1 inch tachometer for a manual ICE Mustang down by the light switch.

Oooh I see it now. My Tesla model 3 did the same thing, although apparently never this severe (and I never owned it in winter).

Yeah it seems like that 5 minutes turns into perpetuity if you're doing ~80 mph and then takes quite a while to fall off after you slow down. low 50s temps I guess could make it worse but it seems weird that batteries can be too cold and too hot at the same time.

 

[Frankie]

Could be worse. I haven’t seen any indication that Ford plans to add it to non-GT models at all. We currently can’t even tell if the car is consuming power or generating power. I’d be thrilled to get the tiny power meter at this point.

They could also make the seating surfaces out of cactus but I'm not going to thank my lucky stars that they didn't.

If other people’s MMEs had seating surfaces made out of cactus, I would absolutely thank my lucky stars that mine didn’t.

Has anyone ever seen this many? What the hell? Forget about being slower than a 2.0T Accord with this many bars, I'm pretty sure the thing was slower than a Prius. I took a video of 0-60 which seemed like it was 8 seconds or so but need to figure out if I can edit a timer into it to see for sure.

The formula is pretty straightforward at this point. No clue why you haven’t figured it out yet.

The car is equipped with infrared cameras to monitor your eyes during Bluecruise.

The car is equipped with Bluetooth and Wi-Fi to monitor your social media posts. Every time you talk shiz about your car it adds a grey bar.

To answer your question, that is why no one else has seen this many.

Or you could say "Hey maybe don't make anyone's seats out of cactus because it's dumb."

It absolutely sucks and is stupid that regular Machs don't have the gauge but it also sucks and is stupid that the GTs gauge is so tiny.

My 2014 Accord Hybrid has a huge power/regen gauge what's Ford's excuse for not having one at all on most of their Machs and having a tiny stupid one on the GTs. People need to stop making excuses for Ford's poor engineering.

We can agree on that.

Agreed. We were going 80-90 to Cincinnati yesterday. That plus DCFC made them pretty persistent.

Your picture shows 65% SOC (meaning this point is irrelevant for why you had bars in this moment), but also important to remember that as your pack SOC gets low (below 30%) those bars get larger and larger as voltage starts to significantly suffer. At 7% SOC I had half (maybe less) power as the pack voltage was toast. This is normal. Polestar can’t even maintain highway speeds below ~5%.

It was after DCFC but it stayed that way the rest of the day basically. They never went away (until I stopped for the day). I understand if it happened for like 30 minutes after DCFC but they stayed for hours. I guess its normal for the car but I'd never seen anyone mention anything this bad with other EV's and I didn't really expect the bars to stay around all day.

And the amount of the loss of power was surprising. I got beat to 0-40 mph by an F-150. An F-150 that wasn't racing. Literally ~8.2 seconds to 60. I kinda would expect 5 or 6 seconds but 8? Jeezum crow that's slow.

Just sell your MME PE and leave this forum already. You're obviously very unhappy. Good luck.

I believe a bit of black electrical tape over the offending display would solve this problem.

All the MME's have limited power after certain things like hard acceleration or DCFC. With the GT models there's a power bar that illustrates this. On the Non-GT models it still happens but it's not illustrated in the cluster.

If you look at his picture under the % of charge you'll see a lightning bolt. To the very far right there's bars that show limited power. It's very hard to see in his example, but they are there.

Here's the other post reporting the same issue and an example of a single power limit bar that's more visible: https://www.macheforum.com/site/threads/cold-weather-acceleration.12228/post-299021

Here's a video I took of the limiter in action: https://www.macheforum.com/site/thr...tery-power-to-limit-heating.10416/post-261084

Thanks for sharing these and your earlier video post.

So is there a way to fix this software wise? Just a cooling issue with the battery or is the management of it to be extra safe? I'm all for extra safety personally, but they should have resolved this probably before launch. It'd be nice if there was a roadmap to fix this for GT versions of the car.

I suppose with me having no plans to be a speed demon and never having any plans neither to really do much sporty driving myself, this issue will probably never affect me, but sorta annoying even though it seems EVs have to do this if you were to track one of these cars.

I think if I were to ever do launches (like never) or track an EV, I'd probably lean towards a future Porsche instead or even a Tesla (gasp).

This is only the second time I've seen someone who has a constant number of high bars. That's not normal...

I wouldn't worry about it unless you're experiencing the same issue as the OP.

0-60 in 8 seconds, now that's funny right there!
