Deep Sleep Poll Hybrid Owners

[Tom201326]

The starter battery in a traditional car needs lots of "cranking amps". Lots of current.

Computers and relays need very little current. A camera battery at proper voltage would probably get the Maverick Hybrid started, since very little 12v current is needed.

IF THE VOLTAGE is too low, correct. The truck will not start. Due to the sensitivity of the electronics, the hybrid may be even more susceptible to a deficit of voltage, while a traditional car is more affected by lack of current.

Appreciate the info, GPSMan. I always thought that the 12v battery would act as the starter battery, while the main battery would act as a "drive" battery.

Speaking of voltage, that's what I'm afraid of right now, especially because I came into the Mav today and my cigarette extension reads 11.6v, which is pretty low. I might go ahead and pull the trigger on a new battery.

I'm going to get a new battery the first time mine does not start. When I went on my long road trip, I carried a second battery. Turned out, the five 10 hour drives in a row charged the battery to the highest point it had been in a year.

This thing acts like the only charge is trickle charge.

Today:

Above : Low (ish) HV battery, just 1 amp going to the 12 volt.


Below : High HV battery, just 1 amp going to the 12 v

Bottom: 3 minutes later, zero amps going to the 12v battery.

The HV battery is only allowed to be 28% to 72% in special conditions. 30% to 70% in normal conditions. But typical operating strategy keeps the battery about 40% to 60%. I wondered if keeping the HV battery lower reduces 12 volt charging. I've found no such correlation.

My issue is getting more frequent. At least once a week I get the notification. It doesn’t make sense that an app is killing the battery at this rate. I’ve noticed my mileage is going down: from 42 to 37 to 34 on my recent tank of 100 miles. Is the engine kicking in more to charge the 12v batt? I always lock my doors but in less than a minute the truck is clicking and popping like a Star Wars droid.

Very very HIGHLY unlikely the engine is running more because of the 12v battery.

Lower MPG comes with lower temperatures; always, and it is a significant hit. In any vehicle. Just us Hybrid owners tend to measure more closely.

Peak MPG is at about 75 to 80°F.

I'll get measurably lower MPG at 65°F than 75°F.

I'm not to the point where I'm worrying about it too much yet. I'll start worrying as soon as it needs jumped.

I forget the details , but service manual outlines a relatively simple way of measuring parasitic draw. Think initial test can be done at the battery inside cab. Max spec is 0.025A. Should be easy to measure unless that draw comes at random spikes.

Lastly, I think many modern cars do have a battery saver mode, but it's not as obvious as Ford makes it from my research online. Also Many have reported numerous deep sleeps with truck starting no problem

If Ford didn't offer remote start via app but kept all other connectivity features AND was able to keep domw lights / key remote unlock during deep sleep - without a dumb app notification then 99% of people would never know.

Yes these battery saver modes do trigger in many vehicles and like you said if the lights stayed on and the vehicle starts nobody would notice.

Thanks for sharing this data with us. How is your system measuring state of charge and charging current for the 12V battery?

Did you install an aftermarket sensor to monitor current flow in and out of the battery, or do you just have some type of computer that’s pulling this information from the OBD port?

It is a ScanGaugeIII (version 3) in this image above.

It pulls data from the OBDII port.

i just got my first deep sleep message last night. but i didn’t see it until i had already done a remote start. so i guess it wasn’t really asleep?

Interesting nore about batteries.
Johnson controls sold off battery business to clarios in 2019. Unclear if it was just a rename and all manufacturing remained unchanged or not.

https://batteryquery.com/who-makes-motorcraft-batteries/

On that page there is mention of a speciality clarios battery

"The Clarios XEV, on the other hand, is the best option for EV and Hybrid cars.If your car is an EV and a modern one with technologies like Lidar and radar, you need smart AGM intelligent batteries"

Diehard also has EV batteries and they are AGM as well.... Maybe, current battery choice is not the best decision Ford made ?

I found something very interesting in FORScan with how my truck is configured. I've dealt with "Deep Sleep" and no start issues frequently in the year that I've owned the truck.

My truck's unmodified Bdycm module information is attached. FORScan reports the Bdycm thinks the factory installed battery in my hybrid is AGM, and reports an incorrectly configured battery type. The battery SOC is also being limited to 80%. The stock battery in the hybrid is a BXT99RT4A, which is FLA.

Is there anyone here with a Maverick hybrid, FORScan, and not having deep sleep issues? Would they be able to check their battery settings in FORscan?

It's more likely that you have a regular battery (non AGM) but setting in forescan is incorrect. Seen that mention couple times before.

Heck, do us a favor and lift the rear seat..take a pic.

Edit: misread your post. Yes, someone else with a hybrid needs to confirm forescan setting. If I had a way, I'd do it now.

This is the one I installed. Haven't had any deep sleep since, but it's only been a few months. My stock battery didn't start giving me deep sleep issues until about 8-9 months after buying the truck.

I did start locking my truck while in the garage, maybe that helps.

I'm not going to disable Ford pass, that's how I get notifications if my Perimeter Plus alarm has been set.

Just checked, 2022 Hybrid, and it shows AGM. I dont have an AGM battery.

Not sure if anyone with a Hybrid has changed this?
If I start getting deep sleep messages again I will definitely change it.

Crazy that this is still an issue two and a half years later.
