- At the charging stations, daily concentrations of dangerous air particles, known as PM2.5, ranged from 7.3 to 39.0 micrograms per cubic meter.
- Urban sites without fast-charging stations had concentrations of PM2.5 ranging from only 3.6 to 12.4 micrograms per cubic meter.
- The tiny particles likely come from particle resuspension around Direct Current Fast Charging power cabinets. Cooling fans designed to prevent the electronics from overheating can also stir up dust and particles from internal surfaces.
a) that doesn’t really sound like the fault of EVs or the charging stations themselves. Any sort of very moderate air current would cause the same problem.
b) that sounds pretty easy to fix with some filters simple pleated filters, and that would leave the surrounding environment cleaner than they used to be.
From the people who think windmills cause cancer?
Also they’re likely in more densely populated areas which already have lower air quality.
This seems accounted for since the comparative samples are from “similarly urban areas”
