My Tesla 3 charges at 7kWh at home on Podpoint charger and that is what the car tells me it is doing. On Saturday I went to charge at a Shell Recharge using type two charger rated at 43kwh. My car said it was charging at 12kwh. Then yesterday I stopped at a Tesla supercharger and used the CCS charger rated at 150kwh and car said it was charging at 37kwh (and that is the speed I have been billed at). The car had advised me to stop at the supercharger and said the battery was being prepared for Super chanrging. I am I reading things incorrectly or should I be looking at Amps or something else.
