Incorrect assumptions that manually update

How about use the max amount of change the car can accept vs the charging station when figuring charging times? You make an assumption of 350 or 400 for a car with a theoretical max of 120 and a real world of 50 to 60 and give no way for us to update. You app designers felt something like choosing the color of your car is more important than the actual accurate number needed to figure out the trip. Seriously this should be basic stuff. Give me the option to put my vehicle accepts not what The charging station potentially theoretically might give me.
