I initially looked at the site right after midnight. The next morning I had some further data download and more mileage. The kwh usage went to 13.1. I was averaging 3.9 miles/kwh. If I remember right the mileage was down in the 20s. Does that seem accurate?.
As others have said, CarWings is suspect. But no one seems to have pointed to the elephant in the room. When you say "mileage was down in the 20s," and earlier "the car said I had 101 miles with the ac on," You are talking about that big lying number on the dash. Accurate?? NO WAY! That number is never accurate. We call it the GuessOMeter (or GOM) because the car's computer is just making some wild guesses about what you are going to do based on what it has seen in the recent past. In general (though not always) it is way optimistic when the battery is full. In general (and almost always) it is somewhat pessimistic when the battery is getting low. Most of the time you will be far better off ignoring that number and watching the bars around it.
As TomT said, the usable capacity is about 21kWh, not 24kWh. It's sometimes even less than that, depending on battery temperature, age, and how nice you have been to it. But let's assume you used 13.1/21 = 62% of what you can use.
Tony's chart says you probably had four bars still showing, and if you kept driving at 3.9 m/kWh you could have gone more than 30 miles farther. Actually, you could have gone farther than that, because what the car's computer doesn't understand, but you know, is that you will become more cautious when you see those last few bars disappearing. You will slow down, accelerate more gently, go lighter on the brakes, turn off the heater and AC, and probably end up getting more like 4.5 or 5.0 m/kWh the rest of the way. And that, Tony's chart says, means you can still go up to 40 miles.
