I took my first road trip with a 2023 Bolt EUV over the weekend and wanted to share my experience.
Basics
Northeast USA
Around 100mi (160km) each way
Overnight stay with charging at destination
Since getting my car, I've been limiting its max charge to around 80%, as I usually don't drive more than 50mi (80km) in a day. Of course the night before this trip, I let it charge to 100% at home.
About 2/3 miles were on the interstate, so traveling around 70-75mph (120 km/h). My main curiosity was around efficiency loss at those speeds. I knew we'd have plenty of range buffer, but I was treating this trip as a trial run before we go for longer distances. We arrived at our destination with about 50% charge remaining, so there was definitely some efficiency loss, but nothing too drastic – my friend has a Nissan Leaf and warned me about highway speeds, but her experience seems more negative than mine was.
We arrived at our museum/destination with several Chargepoint stations, and my inconsiderate/oblivious self picked a bay that already had a car charging at it. As a result, I was charging at half speed for a while (and affect the other driver's charge speed). After about 2 hours, they topped off and my car switched to faster charging. Total cost to charge back to 100% was about $10 - this included energy costs and parking time.
Overall, it was a very stress-free trip, and gave me confidence to try something longer. I also learned a few things for next time (especially about being a good EV citizen). For longer trips, I know that the Bolt has slow DC Fast Charging, so I'm hesitant to rely on that too much (also, the non-Tesla network is sparse), but I might try a few Fast Chargers just to test them out.
Thats excellent news and thank you for the in-depth write-up! It is good that you are mindful about the charging speeds and all that. I'm going to be going in my EV6 soon on a 400 mile road trip *(round trip) soon and I am excited for the headaches!
