Had just about enough of battery saver and deep sleep

[icegradner]

Wasn't everyone praising the the maverick hybrid is based on those 500k mile NY taxis escape hybrids....bulletproof...bull$hit.

It must be a modern Ford thing, something is terribly wrong with battery management on these Maverick Hybrids. My 14 Camry Hybrid had the original 12v battery. My sisters family just replaced the 12v battery on their 16 year old Prius. Both used high quality Panasonic AGM batteries, these Mavericks must be using the cheapest junk lead acid batteries known to man.

If I'm not going to drive it for several days, I put it on a battery tender. I've not had any battery issues so far in ~6k miles.

I have 2022 first edition lariat almost 25k miles 22 months. Never had deep sleep but have had no dome lights on occasion maybe 4 times. After TSB 23E07 and 23E09 at about 22.5k miles truck seems to charge and run better 1-2 mpg better (maybe?). Also had TSB for engine fire holes in air dam and removal of two of radiator air slats. Have not had the yet undetermined solution for engine fire done. Did also have the positive overlay cable TSB performed. Also had the side curtain air bag replacement done which resulted in the exposed edge of headliner. Dealer has one on order and has been great with service some of which has been remote in my driveway and some with pickup my truck at home and return it after service call or TSB. Just had truck sit 4 nights 2 less than 15°F and it started right up. Note: startup was in am temp at 21°F PowerPoint monitor showed 12v bus at 15.5 volts heating everything including wheel and drivers seat. Only placed maintainer on battery once at about 20 months for six days (should have done so sooner but never did). I will use a maintainer about every three months going forward.

I have a 2010 Prius on it's second 12v battery. Car is driven once every 3-4 days. Absolutely zero issue with no starts etc ever in it's lifetime.

This is a Ford Maverick issue (and possibly other models as well) and they need to get on this. I have kept my Mav in my garage for the past week (not driven) hooked up to a 600mah battery tender and it's still in battery saver mode.

You buy a brand new car you should never, ever have to worry about it starting. I drive a 28 year old car 200+ miles each way to work a few times a month because I don't worry about being stranded in it, meanwhile the Mav sits in the garage.

It's still in battery saver mode because the majority if not all the 600mah is going to support the phantom draw. I suggest at least a 2amp maintainer. I have a noco genius 5 which can take 3-4 days depending on soc. It drops into stand by mode since it adjusts for ambient temp so it may top it off if temp changes plus it reactivates charging every day or two to top off that used by the over night discharging.

Engineering = likely fixed by software update
Stock battery crap = with work, Ford could remedy with some increased cost
Loose connections = where is the question. That we will never know
BMS = did the legendary escape hybrid have these issues ?
FordPass \ overall data collection = possibly as these are the first things to get disabled once in saver mode

Deep sleep is the dumbest thing Ford could have made customers aware of. Gives people ZERO confidence.

You’re not wrong.

Yes the original Hybrid Escape was bulletproof. Fewer bells and whistles. But solid.

For those with a fob remote start...doesn't that work even of it's in deep sleep ?

I bet complete removal of the TCU / pulling fuse / disabling all FordPass related features along with WIFI will solve these issues for 97.5% of people. Of course get a fresh battery with it for a fresh start.

Maybe Ford severely failed with trying to make these things severely connected.

I had a tech out for my recall (turn signal). Guy showed me their system (forget what it's called) but he said they can see remotely everything that FordPass can see at any time.

Yes, as long as the battery isn't super low (well be low normal deep sleep).

Truck goes 2 days without driving into battery saver and less than a week for deep sleep, all updates done dealer bench tested battery twice and it has passed.
Fist 6 months it took 2 weeks to go to deep sleep ( sometime I travel on business and drive other vehicle)
Not sure if this is what you guys are seeing but it's super annoying

Hey Ford forum monitoring person: How about you get in touch with your crack engineers and ask WTF is going on with this deep sleep issue? When you get it figured out, post a solution. I, for one am sick of dealing with it. It's a new truck. I shouldn't have to charge the frickin battery.

Yep I'm aware. 600mah is very little. Just a little infuriating. That's a pretty big draw for a new vehicle.

I'm looking hard at getting a new charger for it, we just shouldn't have to. I love the vehicle but this is BS.

I know shouldn't have to but with all the electronic NON airgap switches and relays there is bound to be more problems with all manufacturers. I think possibly Ford has not balanced recharging and battery size. I just came out of a 2012 Honda crv which would eat a battery in 26-32 months if it was not put on maintainer every 3-4 months also to get voltage up to 14.4v on bus had to keep cabin fan on level 2 and DLR on. Time will reveal actual issues. My brother in law has a 2018 GM SUV that has essentially the same issues without the big sleep shutdown just check engine lights and random things (it is not a hybrid).

Fix it yourself and be done.......

Good luck
.

Still haven’t had a deep sleep since you changed? That’s great news.

Try the Battery Management System reset. This solved my deep sleep issues :

1. Turn the key to the ON position
2. Pull the High Beam lever 5 times
3. Step on the brake pedal 3 times
4. Turn the key to OFF
5. Turn the key back to ON
6. Look for the RED Battery Icon to flash 4 times. (three plus a short 4th)
You should be good to go.

Temp fix, longest it fixed mine was about 5 months.

So far so good. Best I’ve experienced thus far.

I have the specs. They are also buried in these threads somewhere but I find the search function not very helpful usually.

The value is 265 amps at 15v.
4,000 watts at 15 volts.

However, it’s really 32,000 watts capable at 220 volts.

Your 12 volt charging: 25 watts to 100 watts typically.

What is your precise question?

The amount of power needed to recharge a 12 volt battery is trivial.

Trivial.

If it’s not doing it well, someone in engineering messed up, or the stock battery is crap. Or both. There’s also loose or intermittent connectors possible.

Thanks for the numbers but I'm just a little confused. Are these numbers for the starter/generator motor? I had the understanding that this motor only supplied dc power to the internal car 12vdc battery, ICE, and all onboard electrical modules but does not convert any power to the hybrid drive battery.

Also when taking an inventory of all the components and features on my Lariat hybrid 265 amps at 15v is quickly taken up with the power consumption. Yea we like are heated seats, steering wheel, mirrors and heated wipers here in Michigan. I ran through the fuses in the owners manual and took 50% of fuse rating for possible power consumption.

As I understand, the generator does turn unless the vehicle is moving (not sure if starter/generator runs if ICE is running or vise-versa). Short trips in my town 5 to 10 miles every 2-3 days don't give enough charge for the constant battery drain at night.

I have located a voltage data logger and should have it by next week and will install for bench mark then multitude of variable test. The guy at the dealership is going to hate me when I show up with a folder filled with data and graphs. But I did warn him I was a retired engineer..

Power (example “wattage”) is not an issue.

Time is the issue.
People have issues (primarily) with short time run cycles.

Your amperage consumption estimate is way way off.

Heated seats and heated steering, radio, lights take next to nothing current wise compared to moving the vehicle. A few amps. Not a few hundred.

You have two MG’s.
Two motor generators.
The first smaller motor/generator is spinning any time the gas engine is spinning (1% exceptions). The second larger motor generator also called traction motor is spinning any time the wheels are turning.

The electronics can add or subtract load at any time.

Both MG’s can be spun (generate) which is negative torque or drag in the transmission .

Both MG’s can spin (consume power) which is positive torque or power into the transmission.

Going down a hill the traction motor is recharging all batteries from the spinning wheels if you are coasting or braking.

Standing still at a stoplight with engine running the generator is charging all batteries from the engine’s spin.

If the batteries are full, there is no where to send power and the MG’s freewheel.

Even if he agrees with you whether he admits or does not admit you are right there is nothing he can do without reproducing your findings on Fords equipment.
The starter generator operates independently of vehicle movement. It can start the ice and then generate electricity with vehicle in park, neutral or any gear. The ice will run at an efficient rpm with the generator converting surplus torque if needed to furnish the dcdc convertor which can balance current needs with the HVB.

I’ve charged my battery to 100% multiple times and followed this. Still get deep sleep. My biggest peeve with my hybrid.

BMS reset is only for when you put a new battery in.
