Frunk Auxiliary Power Tap / Power Feed Specs (48V and 400W)

[scottf200]

Just saw this novel Ford display on FB that lets you monitor Wattage usage in the Frunk and Cabin up to 2.4kW/2400W

400W is not a lot.

I'd assume that the previous indication from the HTML decode, that these were 2.3kW were incorrect. 400W is usable for lights, front fridge and other smaller users, but these aren't significant enough for a decent winch, now to run hydraulic for lifting a front snowplow etc.

Shame.

But it does look like there is a bit if volume to put something flat under the frunk liner. Like another custom battery, a slimline flat winch etc.

Best way forward for these higher power accessories would be installing a dedicated battery and charging it from the frunk power feed connection.

That way you also avoid something nasty shorting the 48V and you losing SbW.

400W is good enough for a hydrauric winch if it has a small pump. Same with winch. A 12 volt system would require more than 33 amps. Do ICE trucks provide that much current without problems?

only enough to power essentials in a house during power outages.

I was just pointing out the Ford frunk and cabin and its UI.

The rear bed has a lot more power for your house. See b)

• a) "Configured with the top-tier Pro Power Onboard system, the F-150 Lightning can deliver up to 9.6 kilowatts. One circuit serves the sockets in the cabin and the frunk, good for 2.4 kW. "
  
  
• b) "Meanwhile, twin inverters in the rear bed deliver 3.6 kW each, and can be ganged up to a single 240V outlet to act as a single 7.2 kW supply if so desired."

Just for reference - a 6000lb electric winch can draw 220amps at 12v and recommend a really thick cable
So 400w doesn't seem like much in that context, so maybe they don't support front winches?
Here is a link to a Warn winch that draws 358A @12V

Oh yeah? Well, the 48V ain’t gonna be enough power for this bad boy! 4ea 280kW motors on top of 2ea 100kW motors, for 1,320kW of power required. Oh sure, you’ll need an aftermarket bumper to mount it on…

The 16,500lb Warn winch pulls 507 amps…

AS far as ICE cars supplying enough current for a winch, my F150 has electric power steering so it has a 250A alternator. Because power steering takes a lot of power. I'm looking for a 120 or 240V winch suitable for a pickup. ~10,000lb would be great and could plug into one of the rear outlets.

Ah yes, the classic model: "YOUR-MOM-HOISTER-5000".

Great product.

How much power does a snow plow blade need? Lights, a hydraulic pump maybe? I don't know, I live in Arkansas. ?

I will mention that I did watch the whole video and saw they have tap to 48v battery. I'm assuming that will be plenty capacity for winch, though a constant load like a snowplow is likely to be a problem depending on what the spare capacity of the dc dc converter they are using is.

It's common for 12V to have several hundred CCA amps for ICE starter motors. Big diesels even more.

A couple of hundred amps is not uncommon on a decent winch, but you obviously need a decent alternator and battery to achieve this. Most cars have over 100A alternators, some several 100A.

As mentioned before, I am not confident that I would want to connect any non-OEM accessory to the 48V battery directly. This is because I wouldn't want a accessory to short and cause a failure of the SbW whilst driving.

Much safer to add another dedicated battery that charges through that 400W frunk connection through some electrical isolation/DC converter that limits the current.

Are you saying you saw in the following video (from the 1st post) that you saw they have to tap the 48v battery? They said that in the video? Can you point to the the MM:SS location of that? I did not hear that.

There is the 400w switched tap. There is also shown two bolts next to the 48v battery which directly tap said battery. I mean, nobody said anything about that being where winch accessory gets its power, but that is 100% where wrench accessory gets its power.

The steering (front and rear) systems have independent harnesses by themselves.
