I drove to the Kentucky State Fair to work the Kentucky’s Touchstone Energy booth (see next blog post for details). The weather was warm and clear, typical for a Kentucky summer day.
START – 100% charge, 283 mile range. Odometer: 1030.1
I needed to charge my phone on the way, so in addition to the A/C, I was using a USB phone charger roundtrip.
The trip to Louisville: 45 miles of charge used to travel 47 actual miles (average 1.04 actual mile traveled per mile of charge)
Return trip to E’town: 51 miles of charge used to travel 54.2 actual miles (average 1.06 mile traveled per mile of charge)
Compare this to the trip I took to Winchester on 8/17 when I used the A/C but did not charge my phone…
Trip to Winchester: 116 miles of charge used to travel 106 actual miles (average .91 actual mile traveled per mile of charge)
Return trip to E’town: 97 miles of charge used to travel 102.7 miles (average 1.06 mile traveled per mile of charge)
In this limited example, the use of the phone charger didn’t seem to make a difference in how much energy was used per driving segment. If anything, the segment from E’town to Winchester used the most energy/mile and I was not using a charger at the time. Both roundtrips involved using the A/C so I will be interested to compare a trip when the A/C is not in use.
