Here’s a not-so-rosy experience on a road trip… It’s unusual and should not give you the impression that this happens all the time. I would equate it to pulling into a gas station late at night to find that all the pumps are out of order, which I’ve experienced quite a lot in my road tripping with a gas vehicle.
I’d been in Altadena helping a family member with health problems. Someone came out to give me a break and so I headed home. I decided to leave the LA valley in the evening to avoid most of the traffic. I hit traffic on the 210 anyway, so that kept my speed relatively low, but I managed to avoid too much stop-and-go. I still made better time than I would have in the morning or midday. I was also getting much better efficiency than I normally get, so when I got to Barstow, I decided not to stop and kept on toward Needles. I don’t usually like to sit for more than a few hours at a time, but I was feeling good.
I made it to Needles with 51 miles on the guess-o-meter, but an efficiency of 2.5 miles/kWh and 20% remaining charge. A state of charge of 20% on 131 kWh battery is 26 kWh and with 2.5 miles/kWh the range is more like 65 miles, not 51. This was climbing the Cajon Pass, which is well-known for beating down vehicle efficiency. Note: The EPA range estimate for the Lightning is 320 miles, and 2.5 miles/kWh * 131 kWh battery is 328 miles. Freeway-speed (70 mph speed limit) driving for most of it.

I stopped at the Electrify America charging station with the intent of charging to about 50% on the DCFC and then napping while charging on the slower chargers. But the DCFC were stupid slow: 37 kW charge rate is unacceptably slow. I was tired and annoyed.
I had lots of options:
- I could suck it up and go grab a hotel room while the charger dragged on and get a good night’s sleep
- I could move over to the slower chargers and grab a hotel room and get a good night’s sleep and then probably charge a bit more the next morning
- I could go backwards about 3 miles to a brand-T supercharger, which has often had its own problems
- I could go forwards about 3 miles to a brand-T supercharger which has always had its own problems
- I could go forwards another 45 miles to a new EV-Go charging station at a Flying-J truck stop.
I chose option number 5. No I wasn’t worried about the range. I did want to get another hour down the road. I’ve been away from home for 17 of the past 20 days.
So I got back on the road. The truck navigation took on the role of being anxious about my range so I could enjoy the podcast I was listening to. I made it with 7% state of charge and plugged in. Went into the truck stop, used the restroom, washed up a bit, washed the truck’s windows and mirrors, and laid back in the driver’s seat for a nap. The charger was doing great at 165 kW.
I woke up with the battery at 97%. I didn’t need 97%. I needed about 80%. But it was done. And I didn’t set the charge limit on the truck because this charger has an idle fee.
I re-parked away from the chargers, laid out some blankets and a pillow in the bed, crawled in under the tonneau cover, and got a good three or four hours of sleep.
Woke up in the early morning, hit the road, and made it home with 25% remaining charge.
I think I told someone earlier that my regular trip between Northern Arizona and the LA Valley requires two stops. Well, I now know for certain that I only need one stop to climb from sea level back up the mountain on a 473 mile one-way trip. And I only need to get back to about 80% state of charge at that one stop.
