Hopefully no more "Deep Sleep" for a while

[Montana]

The question you should have asked is what battery they replaced it with.

It's not very reassuring that a FORD dealer doesn't know what the deep sleep issue is...

I guess I missed this. Which module is that in?

Does that actually work?
"In other words, the parameter being changed from 80 to 95 via Forscan doesn't appear to have any significant observable impact on your State of Charge, (but putting a charger on your battery might)."

Doesn't appear to have any effect. I set it from 80% to 95% in Nov 2023.

I watched the Maverick charge the 12V battery after using it in accessory mode while using Forscan.

At start @1609 on 4-12: 75% SOC, 25 Amps Charging.

When I stopped monitoring @1704 on 4-12: 80% SOC, 2 Amps Charging.

wondering how the up coming battery software recall will effect this condition, if at all.

Maybe this change does not affect the hybrid like the EB. I noticed via ScanGauge, that the alternator would not charge when the SoC was above 80%. When I changed the the charge level to 95%, my alternator immediately started charging my new AGM battery.

Good point.

Charging System - 2.0L EcoBoost (177kW/240PS) – MI4 - System Operation and Component Description

Charging System
The PCM controlled Smart Charge charging system determines the optimal voltage setpoint for the charging system and communicates this information to the voltage regulator.

The smart regenerative charge system primary strategy is stored in the BCM.
The BCM receives information relating to the battery condition from the battery monitoring sensor via a LIN.
The BCM calculates and sends the set value needed for the generator charging voltage via the HS-CAN to the PCM.
The PCM then adjusts the value received (if necessary) and sends it to the generator via a different LIN.
The charging voltage is adjusted depending on various parameters, such as the current level of engine efficiency.
The smallest possible set value for the generator voltage is 12.2 volts, while the maximum charging voltage can be anywhere between 14.5 and 14.9 volts.
However, when the battery is in a refresh phase, the voltage may occasionally reach up to 15.2 volts.
These refresh phases are required when the battery charge status is 80% over long periods of time, which increases the risk of sulfation in the battery cells.

The PCM simultaneously controls and monitors generator output. When the current consumption is high or the battery is discharged, the PCM raises engine speed as needed to increase generator output. The generator charges the battery and at the same time supplies power for all electrical loads. The battery is more effectively charged with a higher voltage when the battery is cold and a lower voltage when the battery is warm.

The PCM turns off the generator during cranking to reduce the generator load and improve cranking speed.
Once the engine starts, the PCM slowly increases generator output to the desired voltage.
The PCM reports any charging system faults and sends a message through the HS-CAN to the BCM.
The BCM then sends a message over the MS-CAN to the IPC , which controls the charging system warning indicator.
If equipped with a charging system warning indicator, the IPC turns the indicator on or off.
If equipped with a message center, the IPC displays the corresponding message to notify the driver of the condition.
Under certain circumstances, the charging system may have a concern but still keeps the battery charged while the vehicle is running.
The LIN is normally used to initiate charging, but with a fault in this circuit the generator self-excites or begins charging on its own.
The charging system warning indicator is illuminated and/or the corresponding message to notify the driver of the condition is displayed and the generator operates in a default mode (approximately 13.8 volts).


Charging System - 2.5L Duratec – Hybrid (121kW/164PS) (S3) - System Operation and Component Description

12V Battery Charging System

The 12V battery is charged by the DC / DC converter control module.
The BMS continuously monitors the battery state of charge condition and provides the BCM with this information.

The BCM communicates this information to the PCM over the HS-CAN1.
The PCM communicates the battery desired setpoint to the DC / DC converter control module which supplies the necessary charge voltage to the 12V battery.

Battery Monitoring Sensor
The BMS continuously monitors the condition and the state of charge of the 12V battery and provides the BCM with this information.
The BMS also estimates losses in the battery capacity over time.

Body Control Module (BCM)
The BCM monitors the BMS and provides the PCM with battery state of charge information.

Powertrain Control Module (PCM)
The PCM provides desired voltage set point to the DC / DC converter control module.

Direct Current/Direct Current (DC/DC) Converter Control Module
The DC / DC converter control module is responsible for maintaining and charging the 12V battery.
It is enabled when the high voltage battery contractor have closed, providing high-voltage power to the DC DC converter control module.

Didn't think to ask about the replacement battery, but I'm willing to bet it wasn't an upgrade. And yeah, the fact that he didn't have a clue to deep sleep is a bit worrisome.
