Quick question(s) and hope they're not dumb:

1)
With the Jeep being a hybrid, how does the battery work with regards to any added external or peripheral mods etc.
If I:
Upgrade my stereo?
add a light rack?
run an ARB Compressor?
add and run a Winch?
Where does the power come from for those items to operate?
Is it when its running off the gas engine, or how long would I have with the battery for its charge when stopped / off?
Does it interfere or draw from the overall battery in terms of its overall driving and functionality?
Does it alter the cars performance if it does draw from the main source?
I'm debating a 4XE or 3.6L V6 24V VVT eTorque whereI know that there are (2) batteries. Tying to figure out if what I want to add on will work without any potential charging issues.

2)
How does the max regen function work? Im watching videos and theres (not a lot) but those from other car types show coasting or regen / slowing down to charge. How and when do you use that with regards to the a 4XE? Can you use that while driving long distances, and how long would it take to recharge the jeep if you go below the last 20%?

3)
I there still a Start Stop function with the 4XE or it not included / not needed?

Many thanks for taking the time to read my post. I think I will be looking to test drive one (if i find one in my area) and ask a lot of questions to the dealer / sales team so I can make my decision.

Thank you for any help- responses...

Not a dumb question at all.

So the Wrangler 4XE will not have an alternator. Instead, it has a DC to DC converter between the high voltage battery and the 12 volt system. That's where your 12 volt power comes from. Other than that, you'll have the same capability as any other Wrangler. The converter is rated at 2500 watts so it's capable.

So you'll be feeding off the high voltage battery but you'll still have a 12 volt battery too. Power comes from both the traction battery during regen and the eTorque motor/generator when needed.

As far as performance goes, it pretty much works the same. The more electrical power we pull, the more the system will have to work to keep that 12 volt system charged. Keep in mind, the system works to keep the high voltage battery at about 15% when in hybrid mode. Many people think the high voltage battery will run down and the 4XE just becomes a gas vehicle at that point. But it will do what it has to do to keep the big battery around 15% for the sake of power when it's needed and for the sake of keeping the 12 volt system powered.

I'm going to speculate that max regen will come close to allowing 1 foot driving. But I'm also thinking it might be a high level of deceleration when you lift your foot off the accelerator pedal. It would be unlikely that you could ever completely recharge the vehicle with the max regen. It only kicks in when you are decelerating or going down hill. Esave mode, on the other hand, will keep the battery at whatever level it is. I haven't heard if it can actually recharge the battery completely. If it can, that would use a lot of gas in the process because of the added resistance.

I don't know if I hit every question but I hope that helps.

Here's what Jeep says about the 4xe's regen braking

New Jeep® Wrangler 4xe Joins Renegade and Compass 4xe Models in Brand's Global Electric Vehicle Lineup

/PRNewswire/ -- 4xe electric vehicle technology is the natural evolution of nearly 80 years of Jeep® capability leadership Jeep 4xe vehicles provide new levels...

www.prnewswire.com

The Wrangler 4xe hybrid powertrain has three modes of operation, known as E Selec. The driver can select the desired powertrain mode via buttons mounted on the instrument panel, to the left of the steering wheel. Regardless of the mode selected, the Wrangler 4xe operates as hybrid once the battery nears its minimum state of charge.

• Hybrid: The default mode blends torque from the 2.0-liter engine and electric motor. In this mode, the powertrain will use battery power first, then add in propulsion from the 2.0-liter turbocharged I-4 when the battery reaches minimum state of charge
• Electric: The powertrain operates on zero-emission electric power only until the battery reaches the minimum charge or the driver requests more torque (such as wide-open throttle), which engages the 2.0-liter engine
• eSave: Prioritizes propulsion from the 2.0-liter engine, saving the battery charge for later use, such as EV off-roading or urban areas where internal combustion propulsion is restricted. The driver can also choose between Battery Save and Battery Charge during eSave via the Hybrid Electric Pages in the Uconnect monitor

To help optimize the benefit of the E Selec modes, the Wrangler 4xe driver information display and the Uconnect touchscreen feature Eco Coaching Pages. The Eco Coaching Pages let owners monitor power flow and see the impact of regenerative braking, schedule charging times to take advantage of lower electric rates, and view their driving history with a detail of electric and gasoline usage.

Regenerative braking is a key part of the Wrangler 4xe eco-friendly equation. When the driver steps on the brake pedal, the powertrain control engages the maximum available regenerative braking, up to 0.25 g, from the electric motors to slow the vehicle, augmented with the Wrangler's traditional friction brakes. The regenerative braking feature also extends the replacement period for brake pads.

With 4x4 engaged, all four wheels feed torque for regenerative braking, maximizing the energy recovery. Electricity due to regenerative braking is fed to the battery pack to maintain or increase the state of charge.

The Wrangler 4xe also features the ability to maximize regenerative energy production via a driver-selectable Max Regen feature.

When Max Regen is engaged, a more assertive regenerative braking calibration occurs when the vehicle sees zero throttle input from the driver (coasting). Max Regen can slow the Wrangler 4xe faster than standard regenerative braking and generate more electricity for the battery pack. Once selected, the Max Regen feature remains engaged until driver deselects it.

Thank you- really appreciate your time...

Interesting read here. This prompted a question for me. Seeing as I just placed my order for the a 4XE, did I make a mistake by not opting for the tow package with the larger battery?
I don’t tow anything... but just curious about how the ICE will recharge the batteries while I may be set up on a camp site using the batteries for minor peripheral equipment.

any insight appreciated.

Welcome @Jgriffs, congrats on your order. From my understanding the engine won't recharge the battery. If you're parked at a campsite you'll have to find a way to plug in a charger to recharge the battery.

Just install a bigger (700amp) battery. That’s what you get with the towing package.

Question… looking at replacement 12v battery. Just in case. Do I buy the one with start/stop or the one labeled without start/stop??

EDIT: Is the ESS the system with the little battery as well as the 12v?? Because I know the 4xe doesn’t have that.
So I should buy the battery without Start/Stop. Is this correct??
