Nice job with the testing. Something definitely seems wrong and I donāt think 35ā tires are to blame.Just finished another test run with lots more data collected. Any other similar results from this group?
TLDR: Results - My 4xe only goes 14.5 miles on the battery at 60 mph in Electric Mode. After a certain amount of time or miles operating the ICE in Hybrid Mode, I am able to turn Electric Mode back on and able to do this multiple times if I wait long enough for what I am assuming is the battery system to cool down. Caution - Regenerative braking (not just Max Regen) may not always be operational.
8/10/21 ā 2021 Jeep Wrangler 4xe Rubicon Electric Mode Test
Attempted a test drive in Electric Mode only to see how close this vehicle can get to the dash display prediction of 21 battery miles.
Results from two tests conclude this vehicle is only able to go 14.5 miles on battery despite the 21 mile prediction.
Contributing factors: 35ā Tires, AC ON, 94F/87F ambient, two previous failures of the battery coolant pump (prior to new tires).
Test #1 ā 94F ambient, light breeze, flat road, 60 mph using cruise control, Max Regen ON, Electric Mode selected
0-1.3 miles ā Vehicle operated normally on battery.
1.3 miles ā ICE kicked on for approximately 10 seconds then shut off. Remained in Electric Mode.
Traveled 13.3 miles on battery.
At 14.6 miles ā āElectric Mode Unavailableā, ICE turns on and defaults to Hybrid Mode.
Drove 10.3 miles back home on ICE in Hybrid Mode
Test #2 ā 81F ambient, no wind, flat road, 60 mph set using cruise control, Max Regen ON, Electric Mode selected.
0-6.3 miles ā Vehicle operated normally on battery at 60 mph. Average Battery Load 43kW
At 6.4 miles ā āElectric Mode Unavailableā, ICE turns on and defaults to Hybrid Mode.
Engine Load 8kW, Battery Load 30kW.
After 1 minute ā Engine 22kW / Battery 10kW
After 2 minutes ā Engine 21kW / Battery 8kW
After 3 minutes / 8.4 miles combined (6.4 battery / 2.0 ICE) operating in Hybrid Mode, Electric Mode becomes available again and is selected.
Traveled 5.6 miles on battery only. Battery Load 42kW
At 14 miles combined (12 battery / 2 ICE) End of road, must now turn around.
Experienced a Total Loss of all regenerative braking. Only the vehicle brakes are slowing the vehicle down and bringing it to a stop. Charge % needle remains at 0. Accelerated conservatively after turning around and immediately āElectric Mode Unavailableā, ICE turns on and defaults to Hybrid Mode.
Traveled 2.4 miles / 2 minutes 30 seconds on ICE in Hybrid Mode
Engine 21kW / Battery 12kW
At 16.4 miles combined (12 battery / 4.4 ICE) ā Electric Mode becomes available again and is selected
16% life / 4 miles range of battery remaining per the display
Traveled 2 miles on battery only. Battery Load 43kW
At 18.4 miles combined (14 battery / 4.4 ICE) ā āElectric Mode Unavailableā, ICE turns on, and defaults to Hybrid Mode.
Traveled 4 miles / 4 minutes on ICE in Hybrid Mode. Engine 23kW / Battery 11kW
At 22.4 miles combined (14 battery / 8.4 ICE) ā Electric Mode becomes available again.
Traveled .4 mile / 30 seconds on battery only
At 22.8 miles combined (14.4 battery / 8.4 ICE) ā āElectric Mode Unavailableā, ICE turns on and defaults to Hybrid Mode.
Traveled 1.4 miles / 1 minute 10 seconds on ICE in Hybrid Mode. Loads not recorded.
1% life / 1 mile range of battery remaining per the display
At 24.2 miles combined (14.4 battery / 9.8 ICE) ā Electric Mode becomes available again and is selected.
Traveled .1 miles on battery only
At 24.4 miles combined (14.5 battery / 9.8 ICE) ā āElectric Mode Unavailableā, ICE turns on and defaults to Hybrid Mode
After 1.5 miles on ICE in Hybrid Mode, <1% life / 0 miles of battery range remaining per the display.
Electric Mode Unavailable Battery Level Too Low and vehicle is driven 7.4 miles back home on ICE in Hybrid Mode.
