Possible to add 240V plug to my condo electric outside?
You can tee off it, with 100A rated wire (3Cu/1Al).

Also, the run to the apartment will have to be upgraded to that.  It is no longer entitled to the 83% "whole service" derate, since it's no longer carrying tge whole service. 

And then, carry it over to a 100A subpanel.  There, you have appropriate breakers for your charger.
