I went way down the rabbit hole on chargers. This is what I learned by trial and error, and I am 100% satisfied with this result in light of today's cars and available technology. I love to hear about better solutions if you know any.
I have three chargers in my house. They are all exterior chargers but installed inside. They are a Clipper Creek 100 amp charger, another Clipper Creek 80 amp charger and a Tesla 60 amp unit. I had a 60 amp Chargepoint Home Flex for a while and candidly it did work flawlessly. There is/was a weird glitch with those units. I've seen this mentioned elsewhere and I have zero idea whether ChargePoint has fixed this problem (or disagrees that it is a problem). My electrician pointed out to me that the Home Flex model can be configured for a 60 amp circuit but the power supply terminals are too small to accept the correct gauge wire. That bothered me so much that I removed the charger rather than throttle it back (it is software configurable) to 50 amps. I wanted higher amperage charging capacity (trying to future proof, a bit) and -- no kidding -- the Clipper Creek units are beefy tanks compared to the plasticky Home Flex. If you have or are contemplating a Home Flex, you may want to ask your electrician about this.
The Tesla charger seems to work 100% of the time and the one that we have is factory limited to a 60 amp circuit (48 amp charging). The two Clipper Creek ones work perfectly on a BMW Scooter [also factory limited to 48 amps] and a Mercedes EQS. Interestingly, using any Level 2 charger, the Mercedes charge rate is
limited by the car to 9.6 Kw no matter what. I called Benz to confirm this. The 100 amp Clipper Creek unit on my Lucid is super fast -- 18Kw. However, over the course of a full charge, I always get one or two "charging error" shutdowns. The car will restart charging by itself, but only if it is awake or you wake it up. In other words, if I am in my office and I use the app to check the charging state, as soon as the car wakes up it will resume immediately. The 100 amp charger is amazing in that I can go from essentially empty to 100% in roughly 6 hours (I have not timed it or done the math -- but it is really fast for a home setup). I only charged the Lucid a couple of times on the 80 amp Clipper Creek unit and I seem to recall getting the same charging error. I have no idea whether that is related to the car, the chargers, the charger brand ... . It's not a big enough problem to worry about, especially compared to the Clipper Creek's super-fast charging output.
I will say from bitter experience that -- even with a good electrician -- getting enough power to the house to support three fast chargers, installing another panel, balancing house loads and running lots of thick copper wire is not for the faint of heart. For most houses, I bet installing two chargers will be a PITA. Clipper Creek sells a really nice charger that will split the charge between two vehicles simultaneously and automatically divert power to the car that is consuming it (will 100% switch over when one car is done). Of course, that is at the expense of speed, as each car can only draw a maximum of half the charging wattage if both cars are charging. And, of course, the cars have to be next to each other.
I doubt that I would do this again unless I were building a new house or totally renovating an existing house. It is easy to say "learn to share," except my house has two separate garages with an EV in each. Maybe this long and boring narrative contains some information that you can use

Actually for charge point and using all 50 A, you need to provide for 1.25x more which is 62.5A. Next standard size bresker up is 70A. The charge point has #6 terminals. #6 and 90 deg C rated #6 has 75 A ampacity. Often breakers in a residental panel can do 75 deg C. The ampacity for #6 75 deg C rated is 65 A and next size up breaker is 70 A. All of the aformentiond is allowed per NEC. Thus, the temperature rating of the wire and temperature rating of the terminal of the breaker and corresponding ampacity respectivly comply with NEC. Im doing 70 A 75 degrees rated breaker and #6 90 degrees C rated wire to get ghe full 50 A out of charge point. I do agree though its bare minimum to only have #6 terminals in charge point and #4 is desired.
