First a question, I use level two J1772 a lot at hotels, malls, parking structures, etc and even at airports. They are great for charging up over 5-6 hours. You can usually fill your battery in just a few hours. Here is the question: If a vehicle (let's say another Tesla) has been present for a LONG time on that one J1772 charger, is it against proper etiquette to unplug their power cord so you can use it (obviously keeping the persons adapter locked in their charge port)? Is it dangerous to unplug the cord without officially pushing the "stop charging" button INSIDE the car? Ive seen a Tesla sit at a J1772 charger for 6 or 7 hours (more than enough time to get 200 miles of mileage) and wished they would move their EV and open up the spot for others.
A second observation, As more and more drivers get EVs that use plugs like J1772, it would be nice to see an increase in the NUMBER of J1772 chargers around. In reality, it will take a long time for 100's of J1772 chargers to be placed in lots and airport parking lots. In a long term parking lot where people might plug in for 5-10 days, it would be very nice to unplug them once they have reached a full charge rather than everyone waiting for that one person to return from their vacation to Mexico or Hawaii a week later. Can Tesla allow an update where perhaps knocking on the window (or tripping sentry mode) would bring up the SOC on the big screen of someone's vehicle so that others would be able to check the state of charge, confirm that it was "full" (or whatever the person had set it at) and then we would know we could unplug them and plug in ourselves. You could have 4 spots for one J1772 charging post in the middle and EVs could come in and plug their cars in as necessary. Just an idea.
Another option would be a slower charging "quad" plug at airports. Say, one that splits a normal J1772 charger into 4 trickle chargers charging at 5 mph (again, more than enough to charge a vehicle over 3-7 day trips). Or even regular 110 outlets. Im trying to think of inexpensive electrical solutions that allow EV users to keep their vehicle plugged in to charge while they are out of town.
But certainly, unplugging someone who has been sitting in a level 2 charge spot all day would be a good start to spread the "juice" around more easily.
