My last employer did a less elegant but functional solution. Put a relay in the 240v circuit feeding each charger and a badge reader on each pedestal tied to the buildings system. You would “badge in” to a normal door reader on each pedestal which closed the relay for X hours.
They weren’t charging for access, just didn’t want it being used by the public.
