A bit of an old topic, but this doesn't happen much here in Florida. (If there is a better place for this please move the reply, I researched and this thread seemed the best, and no I don't have Facebook.)
This happened to my wife, I wasn't there, and we have a bit of a debate here, so I wanted to hear what others think.
Situation, a free EVSE, at Kohl's, who owns the charger and provides it for their customers, and can provide for one 240V charge from two possible parking places. A man in a Volt, sitting in one spot, she parks in the other. The Volt has the ICE running while he is charging
which I didn't know you could do that, so she thought he was ready to leave and went to speak to him. He said, "No, I've got another 40 minutes." There was no indication anybody he knew was in Kohls. He did know that it was a LEAF, and asked what the range was, my wife said "70 miles, but now that we've used it so much the range is less." Which was the first hint. Toward the end of the conversation he asked if she knew about the Volt, and she said it was "a glorified Prius" just with a bigger battery. That is one point of the debate, I consider the Volt an electric vehicle but including an engine, she considers it a hybrid with a big battery. Now, and prior to the "glorified Prius" statement, not once did he ever inquire about the actual state of charge for the LEAF, but he did mention that there was another charger provided by the city about 10 miles away, but there really should be more chargers installed so more people could charge. My wife then informed him that this specific charger was owned by Kohl's, not the city, and it says right on the charger too it is for Kohl's customers (while shopping). He said that there was a 110V outlet too, implying that she could use that, but she told him that didn't work, as it trips a ground fault, and of course he never offered to switch to the 110V either. One other detail was that he had somehow gone into the parking space so that the charge port was on the wrong side, instead of backing in, and had the cord stretched to the maximum almost breaking, so my wife didn't want to ask such a person to just plug it in to the LEAF when he left. I have on a rare occasion left a note even, and the other person did plug it in without incident.
So I think it can be agreed that at the least he should have asked about the amount of charge remaining, as with the Volt it is a choice, but with the LEAF it isn't moving without.
Then the question is does the LEAF have more right to the charger than the Volt? My wife thinks they do, and further that these almost EVs shouldn't even be able to charge there, since the sign says "EV Charging." I look at it more as an electric vs. gasoline debate, and if you're offsetting it is fine. I also think though that if somebody in a true EV is low and needs the charge, they take priority, even over another EV with an adequate charge.
Now, my wife was there for a good amount of time, but we don't know when the Volt left. So if the Volt left, even at 40 minutes, the charger then sat unused until my wife returned.
The final debate is whether he could have made it home on the charge he had already gotten, which was about about 4 kwh as he had been there over an hour, and if he just had 40 minutes to full had an almost fully charged battery and a range of maybe 40 miles? If so, should he have given the charger to her? Now, what if my wife, instead of being low, just needed the same 40 minute charge to full, and even without charging could make it home? In that case is it "first-come, first-served?" I think so. She did make it home, but with just 20 miles on the GOM, so it was closing in on LBW, but never did hit it.
And finally, should it have made a difference, and the man have given up the EVSE to a lady? She said it seemed that he wanted to show her how much he knew about these vehicles, implying that she was a lady who barely knew how to get the charge port door open, but every time he said something she knew the facts and was able to answer.
