|Charging in Milford, CT.|
Anyway, back to our first electric car road trip. There's a super-charging station in Milford, CT, twenty minutes from my brother's family, so when we were invited down for my sister's birthday dinner, we knew we had to go and take Tess! It was our first time driving our all electric car out of the state, knowing we'd need to charge it on the road before we came home.
It's 138 miles to my brother's house in CT, making it 276 miles round trip. For environmental and battery life purposes, the Tesla normally charges to about 80% capacity, or about 220 miles. This is more than sufficient for Greg's daily commute and lunchtime excursions. For our road trip, we set it to do a maximum capacity charge the night before, giving us an EPA estimate of 262 miles for a max range. That meant that we'd only have to stop and charge at a super charging station for a little while in order to make it comfortably round trip.
Electric cars are like gas cars in that your estimated mileage is very much impacted by how you're driving, how much is in the car, etc. For our road trip, we knew that we weren't going to be driving at the ideal speed of 55 miles per hour, because that's under the speed limit! With two car seats and kids in the back, two pack and plays, twelve bottles of wine, and some additional toddler gear, we had Tess pretty loaded down. It was also cold, and batteries don't really like cold. I also crank the heat for myself and the kids, reducing our efficiency even more.
That said, we still managed to drive at 75% - 80% of the maximum range. (If it estimated the maximum mileage we could get in ideal circumstances and speeds was 20 miles, we'd go 15, etc).
That was perfectly fine with us, since we only needed to hit 50% in order to make it to the charging station in Milford, CT. We made it there with no issues, and in the time it took us to change two kids' diapers and outfits and grab ourselves some iced teas, Tess had charged enough so that we weren't even sure we needed to stop on the way back. We thought about hanging out for a full charge since it'd only take a few more minutes, but decided that since the charging station is directly off the highway and someone always needs a bathroom break or a diaper, we'd just stop quickly on the way home if we needed to. We did stop, and we made it home and did the math and realized we hadn't needed to.
|This made me feel cool. (It doesn't take much.)|
The charging station at the super-charge is a Tesla specific station, reserved for electric vehicles, and it charges about four times faster than our home! It charged at 364 volts, and you could sit in the car and watch your estimated mileage go up in real time. (Kind of cool.) Also, it was free, which is kind of fun when you think about how much it'd cost you to go 276 miles in a gas powered vehicle. (My car gets about 28 miles per gallon best case, meaning I'd need about ten gallons, which is anywhere from $35-$40 lately.)

The charging station in Milford is right at a big rest stop, so we went inside to change the kids and grab iced teas, and Greg could actually check his phone to see how much Tess had charged before we decided to leave! We didn't even take time to sit down with our drinks. The same iphone ap will let him see exactly where his car is, its temperature, how fast it's going, and its estimated remaining mileage, all with the click of a button. (Maybe we WILL let the kids drive this car...)

The verdict for me? I'd definitely take Tess on a road trip again. I have two small children who don't like being cooped up in a car for more than a couple hours, and definitely need to stop and get changed and fed and stretch their legs. The fact that Tess needed to charge for twenty minutes was practically immaterial. (A full drain to a full charge would mean you'd need to stop for a real lunch - more like an hour.)
I think it'd be tougher if we hadn't had a well placed charging station for our trip, but in general, as more charging stations pop up in places, I don't think it's so bad to plan to have lunch somewhere while the car charges. You can drive three to four hours without stopping, which is probably longer than we're able to with small children. The kids' car seats fit in the back with no trouble, and there was plenty of cargo space, and it was a super comfortable and fun ride.
My only complaint is that it sort of slows you down on the highway when people keep boxing you in to check out your car.
