Pro power and AC on at start

[Mal106]

This seems off track. I am asking if there is a way to start the truck and NOT have ANY pro power or AC come on. It seems turning the fan off does the trick as far as the AC is concerned. Haven't figured out the pro power yet. Thanks for all the inputs.

If you open the window for Climate, you'll see OFF.

As to Pro Power, there is no Pro Power on except the in-cab outlets, and they're using no power. If the limit warning bothers you, LOWER it.

The Pro Power On Board involves a DC to AC conversion, and when the process is on, some energy is used even when there is no load on the AC outlets.

That is, there will necessarily be some energy/power used by the circuitry used for the conversion process to put the 120VAC at the outlet, even without a load.

Why?

There is always some so-called idle or quiescent current in the components used to convert from the HV battery DC to the outlet's 120VAC when they (the converter circuitry) are on, load or not.

Yes, even though this is a relatively small amount of energy/power, over time it can add up and is taking energy from the battery, which is why the OP sees the warning about it.

This is different from say your house outlets (in a way) - with no load the house system is not using any energy/power - but of course some energy/power is being expended by the utility to provide your house with energy, for example in the step-down transformers humming up on the pole, the humming means current is flowing through them - transformers are coils of wire and wire has resistance and resistance time current squared means some power lost to heat as well as magnetic fields - the utility also loses some energy/power through the distribution system from generator to transformer.

I use "energy/power" because power is the rate at which energy is used/transferred, and in common usage they are used interchangeably..

Well described chl, thanks. The small amount used when I don't need or want it is, no doubt, negligible. It's the geek in me.

and why we are on that question..... has anyone figured out the timeout for ACC NOT full start... when U use ACC the dc to dc still keeps the 12v battery going BUT it does not spin up the power steering pump and AC compressor tho the fan still comes on in the cab I use pro power quite a bit on a 23 platinum.... but it times out in 30 mins... I know U can override it in drive condition but want to find where in forscan to disable that 30 min timer... for ACC position as well.

If this statement is in fact true, then yes, why wouldn't Pro Power On Board default to off or at least have a setting to make it default to off? Earlier forums here have stated PPoB uses no power if nothing is plugged in.

Ha, me too.

I have an MS in Computers and Electrical Engineering as well as a JD (I work in patents) so I can be really really geeky about stuff...probably annoys people sometimes, I can live with that.

Have to ask Ford about the default but...according to the Ford video about the Lightning PPOB I just watched at the link below, for what it is worth, there will only be 200W of power available to the six outlets in the circuit (cabin and Frunk circuits) when the truck is on "if the system is not turned on."

So the video seems to be saying that PPOB defaults to 'mostly' OFF until you turn it on?

Where does the 200W come from before the PPOB is on? It has to be coming from a battery and a DC-AC inverter somewhere in the truck. The only inverters I am aware of are the 2.4kW and the 7.2kW ones.

Maybe the 2.4kW inverter has a low level (200W) mode when the truck is ON and the PPOB system is at a low level idle and hasn't been fully "turned on" via the menu?

The only other alternative would be that the 12V battery is being used for that 200W, but that would require another inverter and I am unaware of one.

I don't know what other forum posts you mentioned say about it, or how they came up with that conclusion that ZERO energy is used unless something is plugged in. Link to the posts in your reply and I'll read them.

Maybe because 200W is such a low level, the idle power required for that low output was not detected?

From an electrical engineers prespective, if a DC-AC inverter is on (when the truck is on) then it will be using some small amount of energy idling, like the utility generator and pole transformer when you aren't using your toaster.

You may think don't get charged for the idling by the utility (no use indicated by the energy meter at your service entrance) but since some energy IS being used to provide the instant power at your outlets at the expense of the utility, and the utility is a business...so....that idling power is one reason there is a charge for "distribution" on your electric bill above and beyond the charge for what is measured by your meter.

No such thing as a free lunch.

With the Lightning, the battery and DC-AC inverter is the utility generator and transformer equivalent, and to be on when you start the truck an inverter has to be using some energy idling.

BTW, apparently the PPOB system has a "utility idle mode:"

"Help keep your equipment safe and charging while your pickup is parked. You can remove your key, lock your truck, and idle while running Pro Power Onboard in Utility Idle mode. Go to Pro Power on your touchscreen and select Utility Idle. Pro Power will continue to be a power source until fuel or battery power is fully exhausted."

I'm sure they don't mean to suggest running down the HV battery to zero, omg.
