Over the weekend, I stopped to charge my Kona at an EA station. Once the session ended, I was surprised to see that I was charged their tier 2 rate of $0.58/min since my "max charging rate" was only 73.68 kW (below the 76-125 kW range for tier 2). I called them today to discuss and request a credit for the difference to which they confirmed that their official policy is the rate is based off the THEORETICAL maximum of the vehicle, not the actual max charging rate used during the session. They seemed to think this is perfectly acceptable. This got me thinking.. Do any local, state, or federal bodies regulate public EV charging stations billing practices? I'd love to follow-up with the regulators, if I could figure out who to file a complaint with.... ?!
