Sounds like a good way to drain your 12v battery

I’m still tearing through FORScan to find the right module strategy for this.

It’s a capability on other Ford vehicles.

You could just leave the car running and lock it using the keypad on the door. I think there is an option to remove the setting that automatically turns off the vehicle after 30-minutes. This will drain your HVB though.

What are you using that needs these powered all the time?

The BCM controls it. I'm not sure of the coding, or if the plain english section will let you do it. Keyword might be powerpoint timeout. It's been tried in different fords, but never with repeatable results. Most people resort to just rewiring it to a constant 12v source.

I haven't been able to figure it out either. Our Wrangler 4xe has two under hood fuse positions for that outlet. One is full time power while the other slot only powers that outlet when the Jeep is turned on. Pretty handy when I have our 12v refrigerator in the back....

I want to use it for a fridgebox, with a 100kwh battery it should be able to run at least a day without trouble

You will have to leave the ignition ON (not ACC) and disable auto shutdown. Take the key with you obviously and lock the doors.

Leaving the car ignition "on" and disabling the auto off timers seems to do the job.



Does this 12v outlet drain the big main battery or some other battery in dont know about?

There is a small 12V battery under the hood in addition to the main high voltage battery. When the car is on, a DC/DC converter produces 12V from the high voltage battery (works like an alternator on a car). Just like a regular car you have to have the ignition ON to provide charging voltage and prevent the 12V battery from running dead when using larger 12V accessories.

Necro, but... I want the 12v to turn off. When I plugging in a test device (120V adapter) in the trunk it seemed to stay on even after I shut the car, locked, and walked the key away from the car (and then walked back). Am I just impatient and needed to wait longer? My use-case is getting some rear seat heaters so the kiddo doesn't complain when he's in the back carpooling to school. I figure he's a teen he'll leave it on and while I can find some that have an auto-off, that auto-off is still 30 minutes.
