Option for a second hybrid battery

[Bj517]

I noticed it says "DUMMY ARRAY" on side showing, so does that mean it takes up room but does not function so maybe a non-dummy array can be installed for double the power. Or is it a dummy array for safety demonstration purposes since the cover is off. My guess is the latter.

Yeah why would they design, build and install a fake battery pack that does nothing but take up room and weight? "Dummy array" has to mean it's just a demo unit.

A quick google search of the photo shows it is a picture of the inside of the Escape Hybrid battery which the Maverick also uses. Here's more info on the battery in the article from Forbes:

Doubling the existing battery capacity wouldn't be worth the money as in it wouldn't pay for itself before most people have gotten another vehicle.

I always wondered why all four wheels are not also alternators that generate power to extend an EV's range.

It seems that the hub could be an alternator that the wheel bolts to and when the car is moving it is generating electricity. Wouldn't that solve the loss in friction problem that a belt driven alternator has?

What you are describing is a perpetual motion machine. Which is impossible, and ignores losses through friction, heat and efficiency.

Yup, you'll use more energy spinning those alternators than you'll get out of them. Net loss

It would be nice to have double the storage capacity, i get going up a hill and i end up saying if i only had a little more range out of the vehicle, i could make that hill and extend my e mode..i know i could break 60mpg with just a little bit bigger battery..

Of course this is all dependent that the HVB could get topped off by regen braking. I have alot of hills here in the Hill country of Central Texas. Depends on driver style as well.

I have considered visiting the salvage yard and picking up one, the cooling line routing would be the most difficult part of the modification.

Yup, although that's still not all that much battery. The current is a meager 1.1KWH, if you double it that's 2.2KWH so still nothing compared to the 14.4KWH battery in the plugin Escape, which would be adding 12 more of that size battery pack around the vehicle, lol! And even that comparatively huge 14.4KWH battery only gives the Escape Plugin a 30mile electric range, so imagine how useless an EV range a 2.2KWH battery would provide. Not really worth plugging in.

So it may not be a plugin at all, it may just be for a slightly higher performance regular hybrid AWD version. The current 190hp power figure doesn't make sense considering how much horsepower the electric motor is rated for, unless of course the power the electric motor can generate is limited by the current the tiny hybrid battery can provide.

Doubling the tiny battery wouldn't give you any plugin range really to be worthwhile, but it could allow higher currents so that it might be a 225hp AWD hybrid instead. I'd actually prefer that, because if you put heavy batteries on a Maverick chassis, you're decreasing its payload, all else equal. I rather it remain light and just have more power and on-demand AWD.

I believe that the second battery would be for AWD version to allow for the additional Regen amperage and FURTHERMORE the AWD hybrid was cancelled due to anticipated constraint being THE SECOND BATTERY!

Has anyone looked to see if settings can be activated for a second battery? Like maybe hybrid AWD = active or inactive or hybrid HVB #2 active or inactive???

So here's the thing....

Right now I can drive 75% in electric mode. I can drive 9 miles out of 12 on electricity. From the battery I have now.
You can too with technique and practice under 55 MPH.

I do it by a quarter mile with gas engine on, followed by three-quarters of a mile gas engine off. Repeat to infinity. This nets me 57.7 MPG and nearly 800 miles on one tank.

With two battery packs, I'd be able to drive 75% of my miles in electric mode.
It would look like this:

Half a mile with gas engine on, followed by 1.5 mile of gas engine off.

Doubling the battery will NOT double the efficiency. If going downhill, sure, you can capture more regen. But that's about it. So maybe double the battery and get 1% more efficiency? Not worth it MOST of the time. Unless batteries were light weight and cheap.

There are times I too wish for a larger battery. But there's diminishing returns in a hybrid without a plug. A plug-in is a whole different ball game.

The problem with your post is, not taking into consideration of where others live. I live in PHX, you know "Valley Of the Sun" we use the AC a lot, which eats into your MPG, and also eats into battery performance.

Everyone lives in different terrain too, hilly, higher altitude last but not least driving styles. Not everyone want to drive like Grandma....

I don't understand your point. Was there one?
You're in the valley of the sun. Fine.
You get 28 MPG. Fine.
Double your battery and you won't get much above 28 MPG either is the point I made.

The efficiency comes from the system, not from the battery, as without a plug-in the energy, all the energy has to come from
Gasoline. Hybrids are great.
The same kWh of battery storage can help 100 hybrid drivers or 1 EV driver is my point.

Heat has everything to do with the efficiency of the battery. EVERYTHING.

I'm noticing hotter the better.
As long as the human occupants can keep the A/C off. These batteries thrive in heat and abhor cold.
Within reason.

Maybe mines broke but it's brand new so I doubt it. I've noted the battery cooling system does not actively cool until 110'F internal battery temperature.

Ford says the HV battery can tolerate paint curing booths up to 140'F. "Anything hotter and the HV battery needs to be removed."

Via 30 second online search Looking at a GENERAL BMS for this type (not the one specifically in the Maverick) the BMS is set to turn off the battery if temperature exceeds 65'C (149'F) and turn the device back on after cooling to 45'C (113'F).

Thermal runaway (aka "fire") begins at 195'C (383'F).

Just some baseline info.
I also know electric drag racers HEAT their batteries before a race. I'm 100% sure this shortens life; but hey, gives you more performance in the short term.

So I guess in AZ you are saying you want two batteries so you can sit in the car and run the Air Conditioning twice as long between engine starts?

THis is just one video, there are many more that will say the heat isn't the battery's friend.
