During a trip from Long Island to Rochester, NY, I had to stop to charge at a supercharger on the NY Thruway. Unfortunately, it was in the middle of a driving rainstorm. I got out of the car, plugged in the charger cord, got back into the car and started the charge. It started and stopped several times, and then quit altogether. The error signal said something about an intermittent charge signal. After several tries with the same results,, I grabbed a hand towel and draped it over the end of the charge cable plug. This time time, everything work fine, and I completed the charge. This result gave me the feeling that the interconnect between the car and the charge cable is well designed, electrically secure and safe.
