Last weekend we stopped at a supercharger with 10 stalls that has been mostly empty during previous visits.
This time, after we plugged in - all 10 stalls were in use, with most used by Model 3's.
As the stalls started emptying, one of the Model 3's tried to switch stalls in order to get faster charger, unaware of what the A/B labels meant - and ended up moving from one stall sharing a charger to another stall also being shared.
This experience highlights the need for Tesla to do more with the onboard software to help owners in using the superchargers.
Some specific suggestions:
1. When at or getting close to a supercharger location, the console should recommend which stalls are the best choice, based on current usage
2. A reminder should be displayed on the console recommending the car be moved when it has completed charging
3. The smartphone app should provide the same type of information - recommended stall(s) to use, and also help with reminding owners to move their cars
Tesla has huge advantages over the other manufacturers because they control the onboard/smartphone app software and the charging stations - and could do more to help more efficiently use and share the superchargers, helping Tesla owners to charge more effectively and helping Tesla to stretch the limited supercharger resources further.
