There are 3,056 public charging stations in the city of Chicago. There are 25,604 electric vehicles registered in Cook County.
Chicago is on the top ten list of cities to charge an EV in North America. You will find a Level 2 or 3 charger – also known as lightning chargers – within ten miles of any major attraction or tourist site
That number of chargers is for the entire region, all the way out to Remington, INDIANA that's 96 miles away from Chicago. See here, where that number presumably came from when you googled "how many EV chargers in Chicago?"
Looking for EV Charging Stations in Chicago-Naperville-Elgin? PlugShare's map has 746 Free EV Charging Stations, 535 Tesla Superchargers, with 3,063 total EV Charging Stations in Chicago-Naperville-Elgin, Illinois.
You're comparing apples to turtles by just googling stuff that sounds kinda plausible but is actually not meaningful.
And no, "Level 3" chargers are not called "Lightning Chargers". You're just making stuff up with that one or you got some weird google results. No one who knows anything about EVs would claim that.
Furthermore, Level 2 chargers in an entire REGION doesn't really matter for people who are traveling along a main route or doing rideshare or even who don't have charging at home, in many cases. The number of DC Fast Chargers (not called Lightning chargers) are FAR smaller. If I'm traveling through Chicago and need to charge (at ~150-250kW), then telling me there's a Level 2 charger in Remington, Indiana, 96 miles away, that charges at 6kW (only 2% of the charge rate of the DC Fast Charger) is completely irrelevant.
For *actual* DC Fast Chargers offering speeds of 150kW+, which someone would want for travel or ride share or home charging replacement, there are about 70 sites in Chicago (both Tesla and non-Tesla). Assuming ~6 chargers per site, that's 420 chargers. A notable number of those chargers are probably broken. Now there are probably 350 left. Pretty huge difference from 3,056 claimed. And not all of those are reasonably close or accessible where the issues happened. As usual, these types of issues tend to be very isolated to a handful of charging sites because of a lot of factors happening simultaneously to cause it.
This is an excellent example of how people who don't really know about EVs can google a couple numbers to rile people up despite providing no practical meaning or analysis.
