If you use the built-in Navigation system, the car will tell you how many Supercharging stops you’ll need to complete and for how long it’ll need to stop for at each Supercharging station, it’ll automatically calculate depending if it’s a V1 - V3 Supercharger station :-)
When Supercharging, you just plug in the cable from the station. Supercharging slows down over time, so you can use the nav to understand the minimum/optimal a amount that you need to charge, though keep in mind the return trip.
Charging slows dramatically as the battery charges, so shorter charges may be more efficient.
If you leave the car at the Supercharger after charging completes or stops, I will be charged idle fees. As such, please plan your charging session so there is no idle time. If needed, you can move the car to a parking spot and then go back to whatever you were doing. Make sure to not idle the car in the Supercharger after charging is complete, or else fees will be assessed by Tesla to me and I will forward them on to you :-)
Please be mindful of the range remaking and don’t run the car until there’s no charge as this will necessitate a flat bed tow to a Tesla service station and this could be very costly.
