Well, here's a first for me. In over three years of driving electric (Roadster and Model S), I have never come close to exhausting the battery pack except on road trips. The other day I actually managed to use up the pack (well 90% of the pack... I didn't realize I needed full range!). So first I gave some friends a ride out to the Carp airport (with the car chock full of luggage, including the frunk), then in to work. Then I was asked to go across the river into Quebec to demonstrate the Model S to some bigwigs. It was freezing cold and I had the doors open most of the time, and the heat on full blast, plus some joy rides (including getting lost once!) and going to lunch. Then my friends have to turn their plane around due to bad weather, and I had to go back out to Carp to retrieve them, and then drop them at my house so they'd have some place to stay for the day. Then back to work. I took that opportunity to plug the car in for 45 minutes, but then a customer arrived for a meeting driving an EV (!) and I gave him the plug. Then I had to run my customer out to the main Ottawa airport (someone else was picking up his EV) and then back to the office again. Then home to pick up my friends and ferry them to the same airport for a commercial flight. Then back home again. Puff Puff Puff. Wow, I spent most of the day in the car! Thanks to the 45 minutes of 70A charging at the office, I had a nice reserve buffer. Although I did need to top up a little, the car handled everything I threw at it. It really goes to show just how capable the Model S is.
