I had this exact issue now at 3 different chargers. One was Syosset about 2 weeks ago and yesterday I had it at two different chargers in Connecticut (Milford and Darien). One I think was due to a pair issue (Milford) but the other two were empty. I call the number and they told me everything was fine with my car and told me to move to another stall. That fixed it, but what if the other stall was not available? They said they would send someone to look at the chargers.
You mention the percent plus the kWs should be between 120 and 130. It does not display the kWs, does it? I know it is just Amps times Volts divided by 1000.
