When I talk to the electro-curious, the first question is “What happens if you run out of battery?” The answer is, I don’t know. It hasn’t come up. My relatively old Tesla holds 230 miles of charge. That’s a lot. There’s plenty of superchargers on every highway and anywhere enough humans live. We’ve driven to Detroit, St. Louis, Boston without a sweat. After five years of ownership, I’m not worried.
We were on vacation in Gulf Shores Alabama. The car was down to 40 miles. Not a problem. We would go into town and get charged up while doing other things. We didn’t expect any problem since we had already visited a supercharger nearby, at The Wharf.
And so Mr. and Mrs. Muttrox, their 18-year-old daughter and 3 of her friends went into for lunch in a caravan of the Tesla and a ‘normal’ gas car. After lunch we went to get groceries, while the girls went to charge up the Tesla and hang out at The Wharf. 90 minutes later we got the call. “Dad, I’m down to 8 miles left, all the roads are closed I can’t get to the charger! What do I do!?” Yikes. Hoo boy. We’ve had these cars for five years and have never yet had to deal with being out of energy at the side of the road. Time to enter crisis mode.
- Girls, immediately pull over to the side of the road. Get out of the car. Turn off your Bluetooth. The Tesla needs to be powered off 100% so it doesn’t lose any more electricity.
We were fortunate to have (1) the extra car that could “scout”, and (2) the Tesla app that lets us track everything, notably location.
- We drove to them (with the aid of the app). Some lady there had said there might be a charger at the Target down that way. Mrs. Muttrox stayed with the Tesla in the heat, the rest of us took the Volvo to check it out. There was no charger. Back to the Tesla.
- The app said the very place we had eaten lunch (Lulus) had a supercharger, and it was the closest one. I had noticed that at lunch but hadn’t seen it in the parking lot. Well, maybe I was an idiot and just missed it. Mrs. Muttrox stayed with the Tesla again, the rest of us drove back to Lulus. I asked the parking traffic guy and sure enough there were some chargers. They were practically camouflaged and blocked off (I forgave himself for missing them), but they sure existed.
- Lulus is four miles away from the car. The car now has only four miles of charge. And those miles are an estimate. Brad didn’t think we could get there. We had to try.
- Thank goodness for Mr. Rodriguez in 11th grade AP physics! I knew that wind resistance goes up as the square of speed (because you are hitting more particles and each particle has higher relative velocity), so I had to keep the speed capped at 30 mph even on the highway. I would drive the Tesla with the Volvo behind me with hazard lights on. I couldn’t run the air conditioner (uses energy), I couldn’t have the windows down (adds wind resistance which uses energy). I would just have to bake while driving.
- I did bake. It was awful. It was over 90 degrees in the direct Florida sun and the car was a sauna. Whenever we got to a red light I lowered the windows to get a small breeze then raised them again when the light turned green. I was stressed about the energy being used by lowering and raising the windows, could that be the difference?
- But we made it! I backed into the spot with 0% left on the battery. I’d never seen 0% before. The attendant told me I needed to straighten out the car. I told him I couldn’t until I had charged up some more, wasn’t sure I could get back the five feet into the space.
- It turned out these weren’t Tesla superchargers, that’s why I missed them before – I was looking for the familiar red and white shapes. These were ordinary level 2 chargers like we have at home. Charging up would take 10 hours. 10 hours is not good enough.

- We sent the Volvo off once more to scout “The Wharf”, the only supercharger in the area. Mrs. Muttrox called me and said it was fine, no idea what our daughter was talking about, it’s all fine, come on over. That was 8 miles away. I waited 30 minutes until I was up to 25 miles charge and headed out. I needed that time to cool down. I felt like a boxer, I must have sweated out a few pounds of water while cooking in that car.
- But I couldn’t get to The Wharf! Everytime I tried to get somewhere, there was a road blocked off. I’d circle to the next area and that would be blocked off also. I was using up my precious miles trying to get to the supercharger, but I was just getting farther away. What the hell is going on!?
- After a testy phone call with Erinn (I get tunnel vision under stress – I solve the problem but act like a jerk while I’m doing it) I realized what was up. One whole bridge was under construction. The Tesla navigation system didn’t understand that and kept trying different ways to get over the bridge. In the Volvo we used Google Maps, which correctly knew the bridge was under construction and just sent her to the next bridge. (Navigation is the same 98% of the time between the systems, and most of the 2% is irrelevant differences. This was the big exception.)
- I pulled into the Wharf with 9 miles left. By now, 9 miles felt like 200. We charged up, everything was fine. What an adventure! I got back to the house seven hours after we had left it. The groceries weren’t in great shape.
I discovered that there are services that come out with a battery, the equivalent of calling AAA for a jump start. It’s called Mobile EV Charging, Bee Charged EV seems to be the major player. Or you can get the car towed to a supercharger.
In the end it all worked out. IMO, five years without ever seriously being close to running out of battery is quite good. Consider what it took to have this problem come up. We had a fairly low charge to start. I didn’t notice the charger at the lunch spot. Major roads were closed for construction. My daughter couldn’t get to the supercharger and didn’t call until we were right at the edge of disaster. The Tesla navigation system didn’t do its job. That’s a lot of things that had to go wrong.
I remain confident that electric cars running out of juice is no more common than ICE cars running out of gas.
