Lets say I go to the Mall and need to charge while there.
Schedule a charging with the station by phone. When its time, the station sends a signal to the car which in turn wakes up and heads for the station (safety pilot option). It backs up and attaches (like some vacuum cleaners). When the charging is done, it detaches and finds the closest parking space. The car notifies you where its parked via your phone and shuts down after you verify you got the message. Dont have a phone! Do it they way its being done now.
Alternatively, it calls you 10 min before charge is done so you can get to it. If it your looking at a 10 to 20 minutes, then this would not be needed. Just wait.
Its the Jetsons! Ok. ITs not going to happen. But no harm done by asking 😎
