Narratives, Photos, and Movies

We took this 3-day roadtrip to Salt Lake City, the city where I was born and raised —ages ago! Tamara had scheduled a doctor’s appointment with her endocrinologist at the University of Utah medical center, so we decided to make a reservation for two nights at a motel near the campus. Like I have done previously with our roadtrips to California in September, and my trip to Texas last June, I decided to break this post into three parts which you can open via these links:


EV Data Summary

Here are the basic EV stats from driving our Hyundai Ioniq 5 “Rocinante” on this roadtrip:

Miles Driven: 747
kWh Used: 223.3 kWh
Average Mi/kWh: 3.34
DC Fast Charges: 6
Average Minutes per Charge: 00:14:35
Total Cost: $0.00


Detailed Breakdown of the EV Data

If readers are want to see more specifics about the miles, charges, and efficiency in Rocinante on this roadtrip, the following table might help fill in those blanks:



There are only a couple of oddities that I should explain in the table. First, when we plugged in at the Electrify America chargers in Salt Lake City on the way home, even though the unit was a 350 kW “Hyper” model, it started charging Rocinante at only 134 kW, and when the session ended it had dropped to 94 kW. I have no idea why that charger was so slow. It wasn’t cold that day. Indeed, our battery’s heater hadn’t turned on to warm it en route to the charger. I can only surmise that the charger was simply faulty.

You will also note in the table that our energy efficiency on the return trip was only 2.6 mi/kWh when we arrived in Scipio, and then 2.5 mi/kWh in Beaver, much lower than on the outbound trip to these same locations. I attribute this to the very strong headwinds we were facing that afternoon. Goes to show what a big difference wind resistence can make when driving an EV!

Finally, as the last columns in the table show, if we’d had to pay for charging at the current Electrify America rate of 56¢ per kWh in Utah, the “fuel” cost would have been higher than if we’d driven our old Subaru Outback, and much higher than in a fuel efficient Honda Civic. I am not looking forward to when our 2 years of free 30-minute sessions runs out in two more months.
