2024 Nautilus software and battery issues

There is no auto start/ stop on the hybrids. The 12v system is charged using a battery management system powered by the high voltage system. the high voltage system is provided power from the smaller electric motor in the eCVT as you suspected. So basically it charges the high voltage system and the high voltage system charges the low voltage system.
Thank you Jacte...I'm an old-school gear-head and just learning the complexities of the eCVT and hybrid. Your explanation makes a lot of sense.
 
So I am perplexed as to how the system continuously charges the 12 volt battery while Electric Driving (at speed or stopped or when auto-start kicks in when driving or stopped)? I have monitored the system real-time while driving and it maintains a constant 14.5 volt charge to the 12 volt battery (just during some recent short trips). I suspect it has to do with the eCVT and/or power from the hybrid drive battery. Can anyone here explain how this works?
I too have been curious as to how/what charges the 12v battery … I have not (yet) found how the 2024 Nautilus handles this, but seems some have an ICE driven alternator and others use a (hi voltage) DC to (12 volt) DC circuit to charge it from the hi voltage battery pack.
 
I just found this on eCVTs!
Back in the day, I worked on a number of standard and automatic transmissions...but this eCVT is unbelievably complex.
Hats off to today's techs that have to turn more brain cells than wrenches!

No problem. I am too, graduated from auto tech school a few decades back and moved on mechanical engineering. The eCVT was so foreign to me i almost dismissed the nautilus. Decided to research it a bit and was very surprised how elegant and robust the system is. These things are more software than hardware. Its just a pair of planetary gearsets with a fixed ratio with 2 electric motors that can slow, hold and even reverse the gearset by manipulating the ring and sun gear speeds/directions. Simple but super complex control and timing.

I don't want to hi-jack this incredibly good thread on the battery issues to the eCVT!
I am just now beginning to understand the relationships between the 12 volt battery, engine, high voltage battery, electric motors and the eCVT and Jacte did a good job of explaining that.

No alternator in the hybrid. Just the generator in the eCVT. Only belt driven accessory is the water pump. the inverter is on top of the transmission and includes a 12v step down.
 
On the hybrid the engine is started using one of the 2 electric motors in the eCVT. There is no traditional starter. It uses the generator motor that also recharges the high voltage battery to start the gas engine using the high voltage battery only. The 12v system is reserved for accessory systems and system computers.
So, when the car dies due to 12V battery no longer supplying the power for the computers, due to parasitic drains, is the jump starter package (like the various ones talked about here) really just providing enough power to get the 12V battery (and therefore the computers) up to a usable voltage, with the hybrid battery pack then doing the main job of starting the car and charging the 12V battery?

Said another way, "A jump start battery for a '24 Nautilus could be trivial size from a CCA perspective, as the 12V battery doesn't do any classic, short duration but high amps, engine starting - it just needs to supply enough power to the 12V battery/computers so there's a usable "12V" voltage, relatively small current, so that the computers can then have the hybrid battery pack supply power to one of the eCVT motors to actually start the ICE. Once everything is up, engine running, the hybrid battery pack then takes care of charging the 12V battery via the BMS."
 
I recently purchased a 2024 Lincoln Nautilis the dealer told me I was the first one in the state of Florida to take possession of the car. Within a few days they called me back to update the software for no particular reason and then within a week of that my battery went dead. I took it in for service, and it went dead again, I took it in for service another time and it continued to drain after they replaced it with a brand new battery now they’re trying to load software to monitor what’s happening to the car and the car won’t accept the software they’re trying to download into my new vehicle my car is only six weeks old I haven’t been able to drive it for three weeks. Has anybody else been having similar software and battery issues?
I am having a similar problem. My gas-powered Nautilus only had 1500 miles on it when the battery died last week and I was locked out. I had driven it the day before. In the two weeks prior to the dead/drained battery, I also received a brief warning on the dashboard, but it didn't show up on my Lincoln Way app. After reading posts here, I'm concerned that my battery is going to drain again. I've also had problems with the software. Since the new battery was installed, the Android Auto app is not working. Settings will not appear, and I have to unlock my phone with each trip. The weather information also blanks out on the dash with each trip. The service department or Lincoln Roadside Assistance were no help. I think the the service staff knows there's major problems with the 2024 Nautilus but have been instructed not to acknowledge this to customers. I sent an email to my salesman who's on vacation until August 11. I have been a satisfied Ford/Lincoln customer for over 40 years, but no more. I'm thinking this vehicle is a lemon.

Yes. As long as there is no high amp load caused by accessory/fans you technically could jump it with a few Duracell 21/23 batteries. Would have to pull all interior light fuses and door chimes but it COULD do it.

4*21700 lithium in series, 3 sets of those in parallel :)
 
I think we need to differentiate between a “dead battery” and a battery depleted just enough to go into “deep sleep mode”

I’ve only experienced the latter last week, and a quick jump brought it to life. Though my wife says she lost some settings. Seat doesn’t go back upon entry and she lost voice command for phone calls. I’ll dig into it tonight to see what we can restore.

So are some of you saying the battery was so dead, it bypassed “sleep mode” and wouldn’t take a jump? Sleep mode is supposed to save the battery from going to dead mode, so is “Sleep Mode” failing as well?

(For reference, we don’t have the hybrid)

I got the jump starter pack today. It’s lead acid, and built like a tank. I decided not to go with the lithium pack. It has a lot of features, but I’m not going to store a 5000Mah lipo in a hot car. I have many lipos for RC planes and cars, and know enough about them to know what they like and don’t like.

I was told by my dealer's service representative that the battery was "drained" (or depleted as you mentioned) and wouldn't hold a charge. I had it jumped three times before taking it to the dealer and the vehicle wouldn't start afterwards.

Great data. You're definitely more ambitious as me as I piddle with the BM300 Pro at home. Our Nautilus is at the dealer service shop. I'll likely install when we get it back.

My only question is whether the app allows you to select AGM vs a standard lead-acid? I ask because I didn't see AGM specifically mentioned in the specs and if it's using a standard lead-acid curve, it's SoC estimates may be slightly off.
Yes...there is a specific AGM selection using the Antigravity Gravity Battery Tracker Plus (virtually identical to the BM300 Pro).

My understanding is there is only one planetary gear assembly in the e-cvt.

How about we start an eCVT thread. Jacyte, what do you think...starting with the video I just sent you, or something else?

I’m down. Let’s collect all the info we have come across. I’ll have to dig back, I found a ton of good info a year or so ago during the wait for order banks to open.

OK, then it just seems a random series of issues, that are loosely connected to each other, but yet still have different outcomes.

Today I can confirm we got the driver seat to retract again. The sleep mode toggled it off (random) and had to reset the feature where it can call someone from voice command…seems the sleep mode deleted the entire contact list (random). Also it now is able to voice text when it couldn’t before. (Bonus random event)

A couple weeks ago I deleted “Phone as a Key” to eliminate any controllable battery usages. I did it in Total Accessory mode (not starting vehicle), all screens immediately went totally blank for 10-15 seconds (oh crap) then one by one came back up. I let settle in for a couple minutes and turned it off, exited and locked the car. About a half hour later, I tried to access the car but the door switches wouldn’t recognize the Key Fob (had to use the fob unlock button). I entered car and did a BMS (Battery Management System) reset…headlights turned to off, car on Total Accessory mode (no foot on brake), wait a minute or so and within 10 seconds…flash high- beams 5 times and step on brakes 3 times (foot off between steps). Within a few seconds, the Battery Light on the dash should flash 3 times (wait for it), if it doesn’t…repeat. I turned the car off and locked the doors. I came back in about an hour, and the door switches still did not recognize the Key Fobs…bummer. Car sat overnight (about 8 hours) and to my surprise, the door switches recognized the Key Fobs in the morning per normal. She’s temperamental!!!
