With the car indicating 40/40 amps I am only getting 32 mi/hr, not the 37 indicated on Tesla's Chart. My wall connector at home delivers exactly what the chart says. I also saw a YouTube video where the car got lower than expected mi/hr for the amperage drawn when connected to a public EVSE using the adapter. Does anyone know why that is? It seams to deify science. If you have the same volts and amps with the wall connector and J1772 you have the same power coming in. So where the rest go: nothing is hot.
