You mentioned issues with a flat 12v battery before. Did you disclose your Fordpass password to local utility company? Or do they use password to your Juicebox for "smart" charging at cheaper rate? https://www.macheforum.com/site/threads/charge-time-error.33030/

Probably a change in the 2023.5 MME.

Does any other sensor (in All Sensors) show correct battery current?

Nope. Veepeak doesn't seem to have low power standby mode, remove it after use. Octopus has very bad reputation for flattening 12v batteries in many EVs.

Maybe some of your electronic gadgets keep draining the 12v battery: https://www.macheforum.com/site/threads/whats-your-favorite-add-on.29690/page-5#post-747563

Quiescent current average (77mA) is probably measured when car is fully asleep, no modules active at all. But as we know, vehicle electronics keeps waking up periodically or randomly. OBD2 dongle will show number of days since '12V battery reset'...

This looks like a free solution without any additional hardware (haven't tested it yet) - AAMirror allows mirroring of the phone screen, but without touch functions on AA: https://github.com/shmykelsa/AAAD https://github.com/croccio/Android-Auto-Store

Actually, there are over 20 screens preloaded in the Mach-E profile: settings >> Dashboard >> reset dashboard to default (Mach-E should be selected as Connection profile)

You probably need a better dongle: Veepeak, Vgate, etc.

What kind of elm327 adapter are you using?

Wow, what is your parasitic standby drain measured by the vehicle (Quiescent current mA in Car Scanner)? I see values between -20mA and -50 mA.

Even if charger delivers 1.2 kW, what gets into battery is less than 1 kW (vehicle electronics takes circa 0.3 kW), as shown by mkhuffman: https://www.macheforum.com/site/threads/hight-voltage-battery-overheating-during-charging-on-l2-after-ota.32486/page-12#post-735734

MME uses not only battery voltage (at rest), but also coulomb-counting to determine the 12V battery SOC (long term current flows to/from the 12V battery). 14.7V is the charging voltage, when the DC-DC converter is active. Do you remove your obd2 dongle for the night? Any dashcam or other...

Instead of external power backup for the dashcam, you will bear the cost of a new 12V battery, sooner or later. Then again. MME has issues with the 12v battery anyway.

I think there is a occassional desulfation in "Battery mode 4" (higher Aux battery voltage): https://www.macheforum.com/site/threads/dead-car-in-winter.13784/page-5#post-339596

Well, your dashcam on OBD2 port probably takes its toll: https://www.macheforum.com/site/threads/dash-cam-and-obd-cable-is-it-an-option-which-one-to-pick.10066/#post-255789 https://www.macheforum.com/site/threads/dash-cam-and-obd-cable-is-it-an-option-which-one-to-pick.10066/page-2#post-255903

14.4V means the DC-DC converter was charging the 12v battery. Both charts show open circuit /resting/ battery voltage - should be measured 12-24 hours after removing from the vehicle. Fully charged AGM battery will reach 13V, a bit higher than normal lead acid battery.

Quite the opposite. Voltage protection is a cheap trick by dashcam suppliers to sell more. The only real Aux battery protection is an expensive Li-Ion battery pack.

This only prevents the 12v battery from discharging in 1 night. Unlike Li-On cells, the 12v battery rapidly degrades due to frequent cycling, the lead-acid chemistry cannot sustain daily discharging/charging cycle. If you run the dashcam in parking mode, anything over 10 months is a borrowed...

That's too late. The parking mode will brick the 12v battery in 8-11 months.
