Quick question, I started charging at a new station recently. I plugged my car in, went to grab a coffee and sit in starbucks for about 45 min to let my i3 charge (since we are having a heatwave right now)and when I get back find my car unplugged and another car next to me charging their car on the charger i was using and my car only partly charged. I thought that if a charger was plugged into our cars and we locked our doors that it would lock the charger in our ports until we unlocked our i3. Is that not the case?
