Anyone else think the “charge” mode in e-select is a joke??

I’m a few weeks in now and can honestly say there is NO WAY that battery will get charged on battery save mode with “charge” selected in e-select and max Regen turned on. I’ve tested this over and over - stop and go traffic, highway, around town, whatever - I barely gain a single mile, once I got 3 miles over a fair amount of driving. What are others experiences? Was really hoping that it would at least keep enough in reserve just from normal driving to give it consistent performance.

Still love it, but underwhelmed on the range.

I believe it is an emission issue. They have to throttle the charging not to exceed them.

Just got my Jeep yesterday so I haven't tested much.

I have a 20 mile mostly highway speed commute to work and switched to E-Save half way. In 10 miles the battery % increased by 3-4% and the battery range stayed right about the same.

Mine is only 4 days old but I found that city driving around 35 45 seems to yield a few miles. Highway not so much.

Thermodynamics dictate ICE recharging is just a bad idea. Only reason I would use it is if I needed extra electricity to use for an inverter.

The 15% reserve that we don't see is a different story. It's a highly efficient range to recharge, it almost comes for free. That's what allows hybrid vehicles to do their thing without depleting.

I've tried it a bunch and while it lets it get down to 95%, it seems to keep it at 95% after that.

Yes, in my testing at 75mph I went from 1% to 18% in 2 hours.

"Charge" is meant for long highway trips/steady low load on the powertrain. At least in my experience with other PHEVs.

Example:
  • You use EV mode down to 30% in the city
  • Get on the highway to go somewhere, will probably be 1hr, turn on Charge mode
  • Get off the highway, battery charge should be increased, let's say 60%
  • Change back to EV mode for going around the city
EV mode is the most effective for stop & go/city driving.

Also remember: The lower your battery percentage, the slower the initial charge rate is. Charging a battery from 5% takes longer for a 10% increase, versus a battery at 70%.
The exact opposite is true. Lithium Ion charges much faster when it is at lower voltage, then slows down at the end as it nears capacity.

Woops that's my bad. I was thinking of my old Outlander PHEV - software limited the low end charge rate "to preserve the battery" and yes you are correct, that last stretch of 90% onward, it slows down too. The "middle" is where you get the highest charge rates.

Also from my understanding the 4XE powertrain differs from other PHEVs. Other PHEVs use their ICE as a generator and only creates electricity for the battery and electric motors, while the 4XE's ICE is actually part of the powertrain.

I have found that esave/Charge is really only effective in town, I can gain percentage pretty quickly in town, but on the highway it wakes 5-10 miles to gain 1%. At freeway speeds there's no extra energy to be directed towards the battery, its all towards propulsion.

I made a couple quick videos about it.
