Since you can get a 60A single-phase 240V breaker, I’d say yes. The question is if your service panel can handle it. Wiring a circuit that size will need thick cables.
Why go for 50A, though? For most people, 30-40A at 240V is more than enough. I drive about 100km daily, and my car only needs a couple of hours to recharge each night.

I read that most single-phase setups top out at 9.2kW. Is that true?

Check out some basic info on EV charging. Not sure where you read that, but it’s not exactly right—unless there’s some context missing. Got a link?

Here’s the article where I saw that info: EV Blog - Understanding single & 3 phase EV charging

Ah, that makes sense now. That info is from the UK, where they usually switch to three-phase sooner. In North America, we use single-phase for higher power levels—typically up to 48kW for residential service, and up to 19.2kW for EV charging if your car can handle it. Most EVs support 11kW, but going beyond 5kW isn’t necessary for a lot of people.

Got it. My hybrid has a small battery and charges slowly, but I make frequent trips, so I thought a faster charger might help.

Makes sense. Next step is to find out your car’s max charging rate, then figure out what setup will work safely with your home’s electrical system. You could post a photo of your electrical panel for more specific advice.
