We had a sub panel installed to be able to charge my Chevy Volt at 240v back in 2011. When we got the Teslas in 2020, we had our electrician put in two chargers in the garage and split the power between, so neither pulls more than 32 amp when charging and they charge at different times. Then last summer we had him come back and redo the whole panel from 100amp to 300amp panel for $800. He's done everything in this house since 1992 and I know he gave me a deal. He said he'd have charged others about $1200 or so. Still only 80A for the garage, but I'm running another line out there myself this summer (50' garage away from house) and I'll have him create two 80amp charger loads. Not sure if I'll get a Lucid charger or just stick with the Tesla wall charger. NACS so the Gravity should be just fine, unless there is some protocol that will be different within, though I doubt as Tesla shared the tech with Lucid via the NACS standard, so all should be good.
