The car controls the draw. Unless the 2019 Volt LT was bought with the 7.2kwH option it won't matter that you have a 7.2kwH capable EVSE, the car will only charge at 3.6kwH. the 2019 Premier has the higher rate standard, the LT is 3.6 unless the 7.2 was purchased as an upgrade.

Regen rate is unaffected either way, this option only affects charging time from the wall.

Regardless, get an EVSE with that capability, it'll come in handy for your next EV.
