Hello All - In an attempt to wrap my head around I Pace’s miles verses kw, I decided to take another short “Test-Ride” this morning to check some usage and charging numbers since the temperature was near 70 today.
I live in North Georgia where our terrain is somewhat hilly, so I selected low regen to avoid regen (braking) on the downgrades to enable the car to coast freely. I also used the throttle to keep the needle centered on downgrades so the car would accelerate freely. There were no pre-heating prior to the trip and no accessories or heat was used. The car is Pre-H244.
The car & battery temperature (garaged) this morning was about 69 degrees. I drove a total of 52 miles, 25 miles at 55-60 mph on a 4 lane, and 27 miles at 35-45 mph on a 2 lane. The car was running a total of 91 minutes.
After a full charge the night before, the GOM showed 275 miles when I first opened the door. As usual, by the time I got down my driveway, I started the trip with 265 miles showing.
I drove about half way and had breakfast, then drove to a park then traveled home (3 legs). The trip totaled 52 miles total. The trip decreased my 265 miles, to only 159 miles. This means it required 106 miles of GOM to travel only 52 miles, or about 2 miles of GOM for each 1 mile traveled.
- After being parked for an hour, I plugged in my Level 2 JuiceBox to top off the battery.
WattCat showed the battery capacity at 51 kw when I began charging. After a full charge, it showed 81.75 kw, or 30.75 kw to fully charge. This figure is not correct since the JuiceBox showed it only delivered 21 kw to fully charge. (with loses)
In retrospect, the IPace showed the battery at 64% w/ 159 miles remaining. After a full charge, JuiceBox shows it delivered 21kw. When I take the 21 kw and divide it by the 52 miles traveled, it shows my consumption at 2.47 miles per Kw. Even more confusing, my IPace journeys logged the 52 miles on three legs @ 3.21/2.58/ 3.72 mi/kw average, far from my true milage.
In conclusion - nothing makes any sense or coincides with any other measurements. The cars actual mileage, GOM, I Pace journeys, WattCatt, are all totally off from each other. Of all the many electric cars I’ve owned, my I Pace is by far the most unpredictable when it comes to achieving projected milage and re-charging.
