I dont see 150 electrical charging stations in Manhattan, unless you include gas stations that have electrical charging and parking lots that offer electrical charging. But even that, I doubt there are 150.

From the article, "They plan on having 105 stations up and running by March 31."
Maybe the OP meant 105, because I didn't see 150 mentioned in that article.
There must be a large number of all electric vehicles in NYC to have that many charging stations. What is the driver supposed to do while waiting for the car to charge? Do they have a lounge with a TV and magazines where people can just sit. Or do they sit in the car and listen to the radio. I can't believe any New Yorker would sit around for an hour or 4 hours while their car charges.
I ran the numbers about 10 yrs ago when The NE US was getting half its juice from coal-- don't know if that's changed at all since then.
My point is that electric cars are not nearly as "good for the environment" as they're cracked up to be by the naive press. The Tesla, a high performance car, is a particularly good example of how the people who would buy it are not particularly well informed but just want to show off. The way to preserve the environment is, by definition, to conserve. Going 0-60 in 4.5sec and traveling at 100mph is not conserving.
One must keep in mind that, while the ICE is only ~10% efficient at turning chemical energy into mechanical energy, gasoline is a remarkably powerful fuel (more punch than an equal amount of TNT), very inexpensive and very portable. A 50cc scooter will get you where you want to go @30mph getting 100mpg. Compare the energy expenditure & poor convenience of the Tesla to that. And what happens to all those spent batteries? Environmental concerns?
All engineering solutions represent compromises between conflicting factors. For most of us, an electric vehicle provides limited benefit, introduces other problems and is very inconvenient.
edited to add: As I recall, my original "Fermi Calculation" involved determining how much co2 was produced to run a conventional gasoline powered car a given distance vs an electric car. Tesla was not available then. I don't recall which electric I used for the calc. A I remember, the electric was a loser if all power came from coal, and you had to get less than half from coal for it to have the advantage in co2 production.

Walk a block or two and shop or eat, have coffee. Get a cab somewhere and go back in a few hours. It's Manhattan.

General Trend Line on Coal is Down. WAY DOWN.
Nobody cares about Olde Coal. Coal is bad enough in the daytime, but the real losses are Overnight, when no one even wants the Power.
Most NEW Generation being built is Renewable (Solar PV and Wind), and Natural Gas is eating Coal's Lunch.

Actually turns out they are MUCH better.
It is you who are out of date.
Good News is YOU . . . . CAN Fix that.

Outta date on that part, too.
There is SOOO much Surplus Electricity Generation at this point -- instead of Conserving, the Edison Institute (Big Electricity Generation Advocacy and Think-Tank) is hoping that Electric Cars may save the Generation Industry from its own Surplus.

[yawn on the Miracles of Oil and ICEs]
Batteries are just a Stop-Gap.
Even Tesla is lagging behind where things are heading.

. . . . He said having NEVER sat in one, let alone driving one . . . Am I right? Huh? Am I Right?

Less than half of US Generation is now Coal, and as noted -- dropping fast.
It will take a few years to get them all off-line.
If they shut Coal down too fast it will all end with Bankruptcy and no one to clean up the Huge Coal Mess (other than All of US and EPA).
