As the number of Tesla vehicles starts increasing significantly over the next year, we'll likely see more public charger contention - at both the destination chargers and superchargers. Tesla could help considerably in managing this through new features added to the Tesla smartphone app (and the console display?). Based on location, Tesla knows that a vehicle is currently charging and at the specific charging location. While they may not be able to tell a specific station or charger, they have enough data to know that the vehicle is connected to and currently using one of the chargers located there. With destination chargers, the location may have a combination of HPWC, J1772 and/or 14-50 charging spots. Superchargers have multiple chargers and A/B charging spots. When a driver approaches a charging location and discovers all usable chargers are currently being used by Tesla vehicles, they could bring up the app, indicate they need charging and ask to be notified when a charger becomes available. When someone is waiting, and one of the vehicles currently charging at the location is finished, that owner would then be notified via smartphone that their charging session has finished and that someone is waiting to use a charger, recommending they move their vehicle to free up their charging spot. And when one of the vehicles that was charging is disconnected and moved, anyone waiting at that location would then be notified a charging spot may be available. This would have helped us considerably last weekend. We selected a hotel on our trip specifically because they had two Tesla-capable charging spots (HPWC and J1772). When we arrived at the hotel late, with less than 20% of charge, we found that both spots were taken by Tesla cars. We had assumed we'd be able to fully recharge overnight - which didn't appear likely because there wasn't any way to notify the drivers/owners of those two cars that someone was waiting for their chargers. In the morning, both of those cars were fully charged, and I was able to disconnect the J1772 adapter from one of the cars and get an hour's worth of charging (20 miles) before we had to leave the hotel. If Tesla had provided some support with the app or smartphone, and notified both of the drivers/owners of the cars that were charging - that someone was waiting for the charger, it's possible one of those drivers might have disconnected earlier - and allowed us to get more of a charge. This is going to happen more frequently - and Tesla could help considerably by adding this small feature to their smartphone app, and possibly also into the car's charging app. We're planning to visit the same hotel next weekend on another road trip, and we'll plan to stay longer at the last supercharger to have enough charge to ensure we can reach the next supercharger, even if we can't recharge at the hotel overnight. Though if we're doing that, it someone defeats the entire reason for staying at a destination charger hotel! Can Tesla help us and other Tesla owners by adding this feature???
