Hundreds of high-speed electric vehicle (EV) charging stations across the U.S. are producing small but notable levels of air pollution, according to a recent study by ScienceDirect, raising concerns as EV infrastructure rapidly expands.
The study, conducted at 50 direct current fast-charging stations in Los Angeles County, California, including many Tesla Superchargers, found that fine particulate matter levels averaged 15.2 micrograms per cubic meter, slightly higher than at gas stations and above World Health Organization air quality guidelines at nearly half of the sites. Researchers attribute the pollution to fans in the charging equipment that disperse dust, tire particles, and brake debris into the air.
