Charging Speed Reduced on Level 2 Public Chargers

jpwe10 · May 6, 2014

I've charged twice at two different public charging stations, one Chargepoint and another at a BP. Both times the car gave me a message that the charge speed was reduced because of "faulty wiring or extension cord". I was getting about 13-16 miles of range per hour versus the 30 or so I should be getting from a level 2.

Is this normal?

Normal if the wiring is bad. Some think the Tesla software is overly cautious but I have not noticed this. 30mph is pretty optimistic for a standard level 2 public charger. That is what I get at home with 40 amps and 240 volts. I usually only get 17-18 mph at public chargers. Most I use are 30 amp, 195 volts.

I'm personally in the boat that says Tesla's software is VERY overly cautious.

I own a chargepoint station. I've always seen 19-20 miles per hour across all the recent software releases. So I'm guessing a wiring issue as well.

We have a Chargepoint Level 2 at my office, and I am charging at 18-19 miles/hour at 30A.
