I was dropping off someone at Dulles Airport near DC this morning and decided to check out the "free" chargers on level 3 of the daily parking. There are 8 spots sharing 4 level2 chargers. 7 spots were occupied (one by a MS with the same brown color as mine). I parked in the only available spot next to a Volt that was plugged in. The charger showed that it was finished charging so I unplugged it from the Volt and started charging mine. I came back an hour later and moved the "hose" back to the Volt. This begs several questions/comments:
- Is it considered normal (or just OK) to unplug a car that's finished charging in order to charge one's car?
- The very fact that I hesitated doing so shows that more signage is needed in areas where chargers are shared.
- Dulles Airport, as do other airports I'm sure, will need to add more chargers pretty soon for them to be more that a mere curiosity. As recently as 12 months ago it was rare to see more than one spot out of the 8 occupied. This is obviously a good sign, but it's not scalable...
