Repurpusing into a pusher trailer, for long trips.
New EVE Cell at RE+ 2023: LF 560K (628Ah Cell)

Sir, you need a lighter pusher trailer. Please, let me help you by taking some of that “weight” off your hands

Catch, make or grow everything you can.
Better put that on a concrete floor! - And attach it to a solid wall!Five 48V packs of the 624Ah cells would fit on here (barely within the weight limit):
Closed Industrial Steel Shelving - 48 x 18 x 75
Enclosed heavy-duty shelves firmly hold gear and supplies in place. 24-gauge steel side and back panels eliminate product roll-off. 20-gauge steel shelves. Welded box beams, front and rear. Holds up to 550 lbs. per shelf. Adjustable in 1 1/2" increments with shelf clips.ULINE offers over 41,000...www.uline.com
Pretty small footprint for 159kWh

That is an awesome idea! a trailer that connects to and EV truck, with more batteries in the trailer to extend range. Damn to many interesting projects to do, to few hours in a day!

Diesel pusher trailer.
Will run on used motor oil.

yeah but I like my idea better!
EV conversion truck,
Removable aux battery pack that fits the bed of the truck, takes up 8" of the bed, but allows for loading above the aux battery,
then a trailer with more cargo space, one level of batteries under the raised floor level plugs into the EV for extra range,
fold-up PV array on each long side of the trailer to feed an inverter inside the trailer for charging upon arrival at destination...guy's gotta have a dream...

You REALLY don’t want to be like the ford guys with the generator and propane tank on their tailgate huh

I started with that plan. But since I already own everything for the diesel version. It made more sense to my wallet.
And it's only going to get used a few times a year.
And also doubles as a power unit for a very large generator.

No range anxiety, it's a diesel electric plug-in hybrid.
I've thought about a self-propelled electric trailer, less invasive implementation of same concept.
But electric around town without trailer in tow would be preferred.

107kWh base EV conversion - 120 280Ah cell battery (384v) between the frames after removal of the engine, trani, transfer case, diffs weight = net zero change.
Aux battery for the truck bed, 6 -48v packs of 280Ah cells for additional 86kWh range extension,
Trailer under-floor cells another 120 280Ah cell battery = 107kWh
Total ESS 300kWh total. Wow, just imagine.
I think a battery pack that fits a truck bed for extended range, only when needed, just makes perfect sense.
Don't haul the battery-weight of an 'extended range' EV all the time, have a normal range -around -town EV with an aux removable battery that exactly fits the truck bed and locks down in place. plugs into the truck to supplement the battery for long range or running tools all day.
Stealing Tim's trailer idea, put another 107kWh battery under a raised trailer floor (low centre of gravity) mount 5.28kW PV on the roof and one side that can be tilted up when at destination, mount an inverter to the inside of the trailer wall...300kWh total ESS and available 5.28kW PV will collect maybe another 25kWh/day, can be stored in just the trailer alone if the truck is out doing truck things all day.

yeah just need to put aside $250k and a 1000 hours or so of 'spare' time. (since there is so much of that - not)
Leads back to: what will these new 628Ah cells cost...and can they send me 120 or so to "test" for them?

At $200 they'd sell decently. The LF304 will probably be down to $115-120/cell next year sale price so that would be a moderate discount per Ah.

$200 per cell, plus shipping, x 120 cells, about $30K for a 241 kWh pack. Would need a REC BMS system to control this - that will be another $10K.
Then there is the job of building a solid case to hold the cells, proper interconnections, yikes, the work this would take. When can we get started?

I believe RAM announced a gas range extender per your design for their upcoming EV truck.

Damn, still going to be buying gasoline,. okay maybe not as much gasoline.
I can tell you guys, I can hardly wait for an EV Truck, with 300+mile range, V2L option, extended range options (bed battery even if I have to build it myself!) and I will no-doubt in my mind about it build the Tim-inspired EV Trailer Range and load extender. Wow we should get that product to market FAST - don't worry that pulling a trailer will cut your range with your new EV Truck, the trailer has it's own battery and will connect to your truck battery to maintain the same range while you pull a trailer!

Put an electric motor for one of the trailer axles and then if the ev fails the trailer can take over

Lightship electric trailer self-propels on the road, self-powers camp
The self-propelled camping trailer has been a near-future-previewing concept explored 'round the world for roughly half a decade now. Silicon Valley startup Lightship has become the latest outfit to throw its hat in that particular ring, and it's assembled a team of Tesla, Rivian, Lucid, Proterra…

from the cell dimensions, 72 thick by 203 tall - about the same as the 280/304's in these directions
but the width 350mm about 14 inches - putting 16 in rows, the double row would be 28 inches wide.
edit: You have to wonder about bloating with the cells this wide, I wonder if compression will be a requirement?
For server rack installations I expect the 280/304's will remain popular. For open shelf install, these new cells may work out lower cost per kWh -yet to see the price for them.
