Add STOP TIME to charging (not just start time) and add Charge Scheduling to Tesla app.
In the Model 3, you can currently set a START TIME for charging. It would be nice to be able to add a STOP TIME as well, to prevent your car from charging when electricity rates may be higher. Also build this charge scheduling feature into the app.
Being able to set a charge START time in the car is useful as it allows you to start charging your car during off-peak hours where you electricity rate may be lower. But for those who charge from a standard 120V plug at 3-4 miles/hour, a single 8-hour or 10-hour charging session may not be long enough to fully charge your car. Currently if you want your car to STOP charging, you have to remember to stop charging either in the car or in the Tesla app.
On more than one occasion, I've forgotten to manually stop charging, which led to my Model 3 charging all day during peak hours. <Insert sad face emoticon here>. Also, the current feature to set a start time for charging is only in the car's control screen, not in the Tesla app.
The new feature I'm proposing is to enable real charge scheduling in both the car and in the Tesla app. It would be done with check-boxes and adjustable times via a scroll-type time adjustment. Example:
Day | Stop Charging | Start Charging
Sunday | all day
Monday | 10:00 AM | 10:00 PM
Tuesday | 10:00 AM | 10:00 PM
Wednesday | 10:00 AM | 10:00 PM
Thursday | 10:00 AM | 10:00 PM
Friday | 10:00 AM | 10:00 PM
Saturday | All Day
