So what I’m getting is correct? Because Charge Points website says 36 miles at 48 kWh.
Chargepoint has no way of knowing your exact driving efficiency. They are using an algorithm that is assuming higher driving efficiency (3.125 mi/kWh). Lightning is usually an optimistic 2.0-2.2 mi/kWh. It's all math.
Sorry I did mistakenly say amps instead of kw. Just and app setting at time of setup for the kw setting. It asks breaker size wired or plugged and I think that’s it.
#1, I wouldn't worry about the kW difference. I asked you in Post #6 to measure your line voltage to the EVSE. What your chart indicates is probably a line voltage of 208V, a normal voltage for a leg of three phase service. By any chance, is this at a business?
10kW = 10,000 Watts/48 Amps = 208 Volts
Another poster asked about whether the electrician installed 6/3 Romex. If he was following the NEC and using that size of Romex cable, he would have set the EVSE to charge at 40Amps, which yields a more likely scenario of your voltage being in the normal residential range of 220-250V: 250 Volts X 40 Amps = 10,000 Watts or 10 kWh.
Edit: Is the Home Flex wired or plugged into a receptacle? I think many of us may have assumed it is hard-wired being on a 60A breaker. Is the wire installed in conduit?
