Sorry if this has been covered, but I couldn't see a specific reference to this. With more and more EVs on the road, I envision a scenario where I show up, but the charger is in use. What I'm wondering is if I can put the J1772 adapter into the car, lock it then leave a note on the other guy's car asking if he'd kindly plug my car in when he leaves. (assuming it is not a for-pay charger, of course). Would the car begin to charge in this scenario, or does some addition step have to be performed to initiate charging? For example, does the car have to be unlocked to initiate, then locked?
