First, having a hybrid Jeep has been awesome for the first month and we love being able to drive electric-only around town! However, like many here, I feel that the range limitations are pretty serious.

Since the Jeep community seems to be able to build everything bigger and better, why not add range-extending batteries! Yes, warranty issues. Yes, big amps are scary. However, the floor in the rear covered with a shelf to make it flat when the seats are down is quite manageable (most batteries are less than 25 mm high). And the factory power packs are right there so wiring would be minimal!

So who has the electrical engineering background to figure out how that could be configured to get to 160 km (100 miles)? 320 km (200 miles)?

All you need is a flux capacitor to generate the power. If lucky you can find them at O'reilly Auto Parts.
You do however need to get your vehicle to 88 MPH to generate power, up to 121 Gigawatts
  • Working Speed (mph): 88
  • Maximum Power: 121 Gigawatts

A little math..... a 17.3kW battery gets you 21 miles Of range. 17.3/21= .82miles per kW.
so you want to go 100 miles, That’ll take .82*100=82kW battery. So 82/17.3=4.7 batteries
So now, all you need to do is find 4 wrecked 4xe Jeep’s, take out their batteries, take out your backseats and stack them on top of each other, hook them up to the car. Presto, 100 mile range.
OR You could go out and buy Tesla power walls, at 14kW, each. Install five Tesla Power Walls in your cargo area. Presto, 100 mile range. Better get bigger springs and axles....
If you want 200m range, better get a strong roof rack, or a small trailer to pull behind you with the batteries....Please send pictures....

Nothing for a stepper.....Please post pictures of the build and as soon as you have it working....please post more pictures.

Jeep should have purchased the Chevy patent on their 'range extender'. Same as the Chevy Volt.

As noted already the getting the correct qty of batteries will not be an issue BUT all the supporting hardware suspension, charging system, frame, brakes etc... to offset the additional 1,000+lbs of batteries will be the hard part. Let alone reprogramming the entire drivetrain to know that there is 1000 extra lbs and another 100KW of power to be utilized I think will be beyond most peoples skill sets.

That's exactly why I suggested the Chevy Volt 'range extender' concept.
Who cares if you have 300 miles of battery range. If his vehicle is an everyday driver the 40 mile range will be sufficient for your daily commute and when you take off to the middle of nowhere the range extender motor will give you up to 500 miles of range. It's a gasoline generator that will power your Jeep at highway speeds all day long if needed.

I know you guys are laughing at this in 2021 but I think come 2025, 2026. Batteries will be cheaper and more Jeep's and Overlander's in general will have a big battery. I think it is highly likely we will see a pack you can add to the trunk space to increase range. I think it's crazy to think this would not be the case.

I wonder if the same people who are negative about the ideas of implementing technolgy here today, were the same people poohooing a hybrid jeep for the past decade?

I'm surprised none of the manufactures have produced a battery "trailer". a tote that would pull behind and for extra storage as well. Would have no effect on suspension or load and within towing capacity. Hook to the hitch when looking for extended range and disconnect when not needed.

Based on the history and rate of change in battery tech is not going to change so quickly, unfortunately. And, yes, i understand history can't predict the future but it's generally a pretty good indicator.

I dunno, would the juice be worth the squeeze(no pun intended).

I know when we pull anything behind the Jeep it's mpg sucks. I truly wonder if you were to pull a trailer with even 500 lbs of battery, 500 lbs of trailer, how much that would affect mpg? Would it be worth it?

As far as I know our biggest problem is aero.

there are already or you can do one fairly easy. Waste of money tough. Biggest cost are the batteries, you can't compete with big companies getting them at a better price, might as well buy straight a vehicle with the appropriate range. There are already on the market. You have the Rivian, it can off road and haul stuff around, same the F150 Lightning.
What I can see, down the road in 5-8 10 years, when the pack is starting to degrade significantly, to have a DIY kit to replace damaged cells, and they might even be lighter or same weight with a bit more power at a very reasonable cost, like it is now for older hybrids like Prius.

I've been pondering lately... what's the setup for the Jeep solar level 2 chargers at like Moab and Rubicon? How many panels, what kind of storage, how heavy is it?

I'm really curious about a power caddy. Image a trailer with a solar array that puts somewhat of a draw on while going down the road, then truly unfolds at the destination for 3x the generation, or more.

Hate to be negative but I'm pretty sure it wouldn't be worth it unless you were staying in the middle of nowhere for a long time. Solar still doesn't generate a lot of power relative to what it takes to propel a flying brick. Under perfect conditions you could probably get a few hundred watts while in motion but the weight and added drag of a trailer will probably consume much more than that at high speeds (at low speeds it might be net positive). Add in the expense of the batteries required and it becomes cost prohibitive for shorter trips. I could see it being great if you were camping for days at a time and could unfold enough panels to generate 1kw/hr or more.

That's kinda what I'm getting at. Anything generated on the road is better than nothing at all, especially if you're already pulling a teardrop. Imagine a Jeep roof rack, on a TT, that when you get to wherever fold out like a Jeep charging station.

Those solar charging stations are self-sufficient. That means the array and storage is enough, why can't that be mobilized?

If you're already pulling it then absolutely! BUT, how will you get it into the HVB while driving? Or are you already pulling storage batteries?

The Jeep charging stations I've seen marketing photos of make me wonder if there are solar fields being utilized outside of the picture... or maybe utility power? But there remote locations makes that seem unlikely. The amount of power they can generate on the solar array is nowhere near adequate to charge a vehicle let alone two. So I'm guessing they're going to use batteries also. And maybe the assumption that there won't be continuous demand so the batteries will be able to charge up more than they're used??? I haven't been able to find specific details or numbers so at this point I'm guessing it's more of a marketing stunt than a practical charging solution, unfortunately.

Oh there HAS to be batteries loaded in that thing.
