I'll just run through the parts involved and mention whether it matters or not.
Breaker--doesn't matter.
Wire--shouldn't matter if it's sized right for the circuit.
Car battery--really doesn't matter. It can take much higher levels of power.
Charging cable--Yeah, this is the one where it might be helpful to lower it some. It is built and rated for 32A maximum, but it gets kind of warm running at maximum level like that, and daily heat cycling of warming up and cooling down does some expanding and contracting of metals and solder joints, so over time, it can just wear out materials faster and may cause your charging cable to have a shorter life. If it's not going to matter if your car takes 5 hours instead of 4 hours to charge while you are sleeping, then I might turn the amps down some into the mid 20's so the heat cycles aren't as big, and it may help it to last a few years longer.
Go ahead and use it at 32A if there's a situation where it's helpful, but for every single day, I would personally keep it a bit less.
