As an EV owner and advocate, whenever I hear "public EV charging location" the immediate question is what the power level is. An "EV charging location" can literally be just a standard NEMA15 outlet, but what most people imagine when they hear those words is a Tesla supercharger or similar.
So digging into the data;
DC Fast Charge: 42,395 chargers across 10,092 locations
AC, Level 2: 131,755 cables across 55,366 locations
AC, Level 1: 813 cables across 186 locations
So the vast majority of these are Level 2 spots, which supply 208-240 volt single phase AC to the vehicle's on-board charger, with the range currently being 3KW to 19KW (though most cars top out at about 9KW). As a very rough gauge multiply that number by 3 to get miles of driving range added per hour, e.g. a L2 spot will get you 9 to 57 miles driveable range with most vehicles and installations getting you around 25-30.
This is is not what most people think of when you mention public EV charging. DC fast chargers start at 50kw for the older units and the current CCS standard in active deployment goes up to 350KW. DC charging curves are not linear and every vehicle is different but we're usually talking on the order of +150 miles in 15 minutes.
