Very tired pony

[Gloff]

My car goes into a deep sleep after only a few hours too. I thought this was normal. I agree with what was said earlier in that it's only a nuisance when you look at your Ford Pass to see the level of charge and it says the car has been in a deep sleep and hasn't updated in hours.

Based on the previous posts, some clarification would help. When you use FP, and it says it hasn't been updated in hours, are you able to refresh and see current State of Charge/location, as well as use the remote functionality, or are those things not working?

The FP system is largely the same and operates on the same principles. My understanding of the post is that FP was not responsive after an hour for the OP as the vehicle is going to deep sleep, which would point to a LV problem.

Going to sleep is normal, guess we got make sure if OP is getting Deep Sleep or normal sleep.

The car doesn't sleep when the LVB is low in the MME. It does only on ICE Ford vehicles. On the MME it would engage the DC/DC charger and top off the LVB. At this point you'll also receive a message in FP and in the car that there's an electrical system drain.

Deep Sleep on the MME only engages after consecutive days off charger and not in use.

It *might* engage under 12% HVB if the LVB gets below 9v, but I don't know if anyone has confirmed that. I say might because under 12% the DC/DC will not kick on to maintain the LVB.

Hey…. Ford …. How is that micro size piece of crap 12 volt battery you decided on to save 50 bucks working out for you.

Probably the culprit in many of the bricking situations since it taxes the entire system with its feeble capacity.

That’s why they hid it under all those panels in the Frunk when it’s needed to be accessed almost weekly.

Jes sayin. Big fail ford. Also really hard to find a replacement Fix in 2023 please

What????

The battery size doesn't matter one bit. Even if it was double the size if it wasn't maintained then it would die. This was an issue in 2020 with the MME and hasn't been an issue since. There's nothing wrong with the size of the battery. Same logic applies to the HVB. The HVB is huge, but if you don't ever charge it then it will die...

The battery size is fine, it's only intended to run the 12v accessories (lights, infotainment, etc). The MME doesn't need a huge capacity and high cranking amps because it doesn't have an engine to turn over. As mentioned in this thread, the 12v system is being charged through a DC/DC inverter by the HVB the capacity is fine.

That's a great point, thank you. That would leads us back to the OP, is actual deep sleep being triggered, or, as you said, is FP still operating normally, just not updating (as intended).

FWIW, I am aware that I was fully wrong on the operation. I was under the impression that it operated similarly to the HEV/PHEV products from prior years (Fusion/C-Max) where the DC/DC was only under operation if the contactors on the HVB where closed (ignition on).

Thank you for the insight/knowledge!

Disagree…. The battery although 12 volt is feeble and has a very low cranking ability
Also the connections are also crap when it’s somewhat depleted it’s one of the factors in the whole channel of electronics that cause other failures. It’s inability to pull a strong charge flows throughout the system. Check out the ancillary batteries used in other electric cars and you’ll see why the entire system through Ford is suspect and likely to change very quickly. NTSB is already looking into it

Jes sayin ..stay tuned. Crap components compile on each other to create a channel of horseshit

BTW. Owned two already both bricked. Two more on order but I may delay them till 2023
The lightning system is much better

I don't think the car is in deep sleep. As I posted on page 1 (here) I think there's some misconception about what sleep is.

I think all the service tickets and worry over this might be for nothing and a Ford service department that's woefully uninformed.

It’a very clear if it’s Deep Sleep cause FP says it at the top, but OP has not confirmed if that is what they are seeing.

You're seriously trolling right? What the hell are you "cranking" in the MME? Did you put a 12 stroke diesel in it? Can you explain how the 12v battery causes electronics to fail? That's the first I've heard of that. Batteries are rated in Amp Hours. A bigger battery doesn't give more than a smaller battery in voltage and CCA is irrelevant. It only gives more in time to depletion.

The NTSB? Is there some massive pileup of MME's that we didn't read about? Maybe you're thinking of NHTSA?

I think I have a bit of insight into what Ford is doing, just saying... The battery isn't gonna change, so don't hold your breath.

This is why I stopped coming to the forums...

Settle down sparky. Who’s trolling whom Since you left the forum ?
whatever. They have problems
Have a nice holiday

I think maybe we should go back to step one here ...

What do you think deep sleep is? Are you talking about FordPass saying "Updated XX hours ago"? Or the message that says "You're seeing the last details your vehicle told us before it went to sleep"?

I have a feeling some people may think the regular sleep is deep sleep.

I frequently get “You’re seeing the last details … before it went to sleep”. Is this not normal. This message appears after the car has sat for 1 hour or more.
