No, that's not how the current ratings work. The amp ratings in the ampacity tables are for the circuit rating. So if you want a 60A circuit, you need to use a gauge that says it can support at least 60A. That wire only goes to 55A, so you can't use it for a 60A rated circuit.
Circuit ratings are normally for intermittent temporary use up to their full ratings. So things like ovens and clothes dryers have heating elements that cycle on and off for several minutes at a time. The wires get time to cool down, so they can run at full 100% capacity for short bursts. But electric code requires that for permanent loads (several hours), they can only run at 80% of the circuit's rated capacity. So that's where the 48A for many continuous hours on a 60A circuit comes in.
But you don't get to evaluate whether you think your charging is going to be short term or long term. Code was modified a few years ago to just define all EV charging as permanent loads.
