I'm probably just going to bite the bullet and replace the panel but this is really good to know. | ||

Another option is just stick to a smaller circuit. 80% of 15A x 120V = 1.4 kW 80% of 20A x 240V = 3.8 kW Just going from a standard 15A outlet to a 20A/240V nearly triples the amount of power, and many homes that would need a new panel for a 50A charger have room for one more 20A circuit. Cars typically spend 8-16 hrs per day stationary in their own driveway, so 3.8 kW translates into tons of range. While 40A or 50A is nice to have, it's far from necessary. | ||

How many amps is your current service? I have 200A service where I live, but the house is 100% electric -- water heater, range, heat pump, washer, dryer, etc. All electric. There's even a little medallion on the front of the house about it: https://i.imgur.com/BrHj1XQ.jpeg The 70s were weird. And when you say that your panel is old, just how old are we talking? | ||
