Does that mean I should hold off getting a 50A charger (Chargepoint) installed in anticipation of the SUV? I'm a novice on these points but vaguely recall Tom explaining at one point that most folks home charging capabilities would be limited by current infrastructure.
If you have the ChargePoint Home Flex, thats a great unit, and should work fine for you, if its the 9.6 kW version, have your electrician hard wire for 11.5kW, or 19.2kW so you can upgrade later without rewiring the circuit. Likely the 40 amp charging will work fine for you, but if it doesn't satisfy your needs you can sell that wallbox and upgrade to a bigger one. We have 2 EV's living off a single 9.6 kW juicebox, and get by just fine, never needed more. I have a Charge Point Home Flex, and the HummerEV Clipper Creek unit on a shelf in the garage I might install someday, but too lazy when the system we have has worked well for us.
Before installing a 19.2kW wallbox you need to access both your electric service capability and also the utility side capability. Many times the utility cannot provide the amperage to the capacity of your service, do simple math in many places in the USA utilities will supply 4 to 8 homes with a single 25 kW transformer, which if you have a 19.2 kW charger, that does not leave much margin for your other electrical needs , and your neighbors. If you start causing voltage drop in your neighbors homes they will not be happy, especially not in the day and age of LED lightbulbs that are very voltage sensitive.
