Tesla - Always be aware of where your electric car is and what its condition is! Before traveling, even if the Tesla was in the garage, it must be warmed up before the trip, check the amount of charging, update the software. If your car has an autopilot function and it is difficult for you to get to it, turn it on and wait for the car to drive up by itself. Even at a distance, you can always connect to the Powerewall to check the charge from solar energy, as well as find the car on the map wherever it is. And many other useful functions in the application.
