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.
