Hi just wondered if anyone can help me with this issue , I have had the CCS retrofit completed on my model S and now when I try and charge on a 50kw fast charger sometimes it will charge and sometimes it will start charging then fault. As I do work on these chargers ( IT wise ) I know it is an over Voltage error . How ever an i3 can charge just fine so I know it is not the charger itself. Sometimes it will charge fine it depends on charger to charger. Note all the fast chargers are the same type on the same network.
