One of the few drawbacks of an EV is still the time you spend charging when taking longer road trips. I've driven about 50k miles on Superchargers doing longer road trips and thanks to Teslafi.com I was able to keep track of drive time vs charge time on a recent 4000 mile road trip. Adding up the numbers it shows the ratio between driving and charging was almost exactly 1:2. In other words, for every hour of driving I spent 30 min charging. The average leg between Superchargers was 117 miles The average drive time on each leg was 1h 32min The average charge time at each SuC was 45 minutes. The average charge speed was 158 mph (car: Model S 85) My average drive speed was 78 mph. It was cold, so the heater used up additional energy. I think the average energy consumption was around 380 Wh/mile. Driving in warmer weather would give slightly slower energy consumption and save some time charging. Driving slower would change the ratio. Slower driving uses less energy and causes shorter charge times, but it also causes longer drive times. While driving slower makes the ratio between charging and driving look 'better', it doesn't help with the overall time. I found that 70-80 mph is roughly the sweet spot to get the overall fastest trip time. At first, the charge speed seems rather low considering that the Supercharger tells you you are charging at 300 mph when you plug in. That's only the charge speed at the beginning when the Supercharger charges at full speed. Over the charge session is slows down quite a bit. It also used 'rated miles' which is unrealistic, especially when you drive faster on freeways. Bottom line is actually sobering. That's a lot of time charging! Trying to replicate the trip in EVTripplanner.com to match my driving speed and temperature I get a ratio of 2.4. So why is it off? I noticed that the EVTripplanner calculated the drive time and energy consumption pretty accurately. The charge times were off, though. That's something I also noticed with the car's trip planner. It always underestimates the time it takes to charge. I always have to charge longer than what the car tells me and that means I spend more time charging at a lower rate. Also the low temperatures eat up energy that cause longer charge times. Doing the exact same trip in warm weather would use 10-20% less energy thus saving time on charging while keeping the same drive speed. One way or another, I think for road trips the charge times are a big time killer. Hopefully Supercharger 3.0 and better batteries will help.
