I have a Chargepoint home Flex and am currently getting quotes to move from the 14-50 NEMA plug to hardwire (going to keep the plug for backup). But the J1772 standard seems to allow up to a maximum 80 amps charging. However, with maybe the exception of Lucid and whatever Ford is doing, most EV's are not going much higher than the 50 amps my Chargepoint "can" support. I'm having a hard time getting the Rivian charged overnight with the current setup.
Chargepoint has a limitation in that the largest wire it can support is 6AWS THHN 90 degree rating. But going up to 80 would require a larger wire, so I can't really future proof by just sticking a 100 amp breaker in there with the supporting wire. I can only go up to 70 amps.
I can't seem to find good information if the industry "thinking" that 48,50 amps is going to continue to be enough for charging EV's going into the future. I don't want to continue paying for upgrading the electrical system as new EVSE's and EV's come out. but right now even the EVSE's are limiting me to 6AWG it seems like.
Thoughts?
