EREV Hybrid F-150 Lightning Announced!

[XLT22]

You need enough power for sustained charging under full load, at least close to it. For example when towing a travel trailer up a mountain pass.
Otherwise you risk having to pull over and wait until the battery re-charges with that small engine. Probably not something that Ford would want to see mentioned in the first real life tests and reviews.
(I'd be ok with that though, btw, because you could plan for a case like that and have enough charge on the battery before entering this rare and extreme towing up a mountain scenario. Especially if they provide a manual override to force charging from the generator).

The gas engine doesn’t charge the battery. In an EREV the generator only runs once you’ve used your 100-150 miles of battery range. The generator then holds the battery at a low, steady state of charge and generates electric current to run the traction motor. RPMs do vary a bit based on the Chinese EREVs being tested here in the states. THR vehicle is intended to be used with the battery as the primary source of energy being recharged with either DC fast chargers or Level 2 charging.

Driving a PHEV or EREV and not charging it makes exactly zero sense.

The ICE powerplant is going to be interesting. I doubt it has to be huge.
Would the 2.5 used in the smaller hybrids like Maverick be ok? Would it be the 2.7 V6? Please God NOT the 1.0 Ecoboost three cylinder. Those smaller EcoBoosts have been nothing but trouble.

The battery has to have a much bigger capacity than the powerboost does today. Guess that means the gas tank will be even smaller than the 26 gallon "Standard" gas tank.

Depends on the kW needed from the range extender. Electric traction motors are so efficient I would guess a larger displacement NA 4 cylinder would work fine. Something like 2.5L to 2.8L.

my guess is they have been sand bagging
i say this based on very very limited adverts for the PB and all its glory
they cut way back on lighting as well over last 2 years, with almost none since January
granted ford always fails to advertise like the other guys, but this year the push has been more towards mach e , mav and ranger. ranger is a huge gain in capabilities, looks, etc
super duty has been quietly scooting along , 26s have minimal changes, most just colors and package adjustments. (cuts)
super duty 7.3 and 6.8 and the boss giant tq monster 6.7 are sort of floating along as well
the 6.7 has a few things they can do to drop emissions and boost lower combust temps and gain a few more getty ups
imo 27 my superduty is going to be some big bananas good stuff

he is talking late 26 or early 27 MY.. thats a big push if they are just at the point to let stuff out

What’s coming first is the Ranger sized battery electric truck. IMO that will be the bigger seller. There’s way more interest in that from fleet managers than the full sizers. Of course I say that seeing local GM dealers unable to keep the electric Silverado in stock because they sell quickly.

Why not use their smallest engine? A 1.0l model from Europe perhaps? It’s only to generate power for the battery and doesn’t drive the wheels.

Cannot generate enough kW to sustain the truck towing. Pretty easy to run the math on kW output versus engine displacement. For an F150/F250 size truck you probably need a 3.5 liter engine, minimum.

 

[dadrew]

I wonder if they could use the 3.3L, if I was a betting man id guess the 2.3 or 2.7 turbo

 

[0o7]

I don't think it would make sense for a forced indication engine as a generator. None of the advantages of forced induction make sense for that application IMO.

I don’t think a turbo in this

Agreed. Also I’m not sure how the ICE win operate as in rpm’s. Turbo engines need heat and high revs to help alleviate carbon build up and help with catalyst function. I’m sure if they do put a turbo motor there will certainly be scenarios where engine will idle/rev higher to get the cycles ran properly. Best way to avoid it, but a N.A. in it. They should put the 5.0 so that way when it kicks in you’ll get the best of both worlds.

I am pretty sure that in an EREV, the gas engine / generator is there to charge the battery once it runs low. And the battery then supplies that power to the electric motor(s). What's considered low battery depends on the programming of the BMS. And in many cases the drive mode. For example, when in tow/haul mode, I am sure that the gas engine/generator will kick in earlier.
Look up the Ramcharger driving modes. There is a battery recharge mode. The battery is (a buffer) between the generator and the electric motors, which guarantees a more steady power flow and minimizes energy "loss" to heat.
An EREV works somewhat similar to a Diesel Locomotive.
BTW, "charging the battery" in this case does not necessarily mean that the SOC increases, it will fluctuate somewhat depending on the load on the electric motors and the generator power output.

The 3.3 NA fleet V6 is a pretty good apples/apples to what Stellantis decided on for the Ramcharger.

Just a thought

That sounds like about the right size.

Can you charge a battery while you are discharging it at the same time?
Or is it per cell controlled? Are the cells on seperate bus bars? Or how does it work? (I do not know that is why I am asking )

Current flows through batteries at different rates all the time.

Think alternator charging, then turn up the AC.

I thought the alternator provides the current for the vehicle plus to the battery. Ergo the current only "flows in" to the battery while the alternator is running. And only "flows out" from the battery when the alternator is not running.
I guess I lived my life in a misunderstanding so far but never late to learn

I am not sure how does charging AND discharging a battery works chemically. There are only two poles to use...

ps) I am a SW engineer so my knowledge is not sound about batteries to say the least. Just trying to understand this.

 

[SAAUZ]

My though was using their 2.5 Atkinson Cycle engine

OK, maybe a better example would be solar powered battery bank, powering a travel trailer. Charge comes in to the batts from the PV, while load goes out from them. All there is to think about, is the resultant charge from the PV, a net positive, or negative number but the flow is varying but constant and can be either, depending on the load, or the PV production, multiple times per day.
