I've tried looking around, but cant really find what I'm needing. I just got a 2018 chevy volt (love it) and I can charge at home at 8 or 12 amps (which takes forever, but I still love it) The question is by my work we have a free 240 charger. I figured it would be fast. I plugged it in this morning with about 10 miles of ev left and it says it will be done around 12:30. If it just takes that long its fine, I just want to make sure its not a setting or something I'm doing weird. Thanks in advance for any help.
