More Evidence Suggests Electric Cars Need Night Time Charging

Washington DC (SPX)

Researchers in America have shown that ozone-a known pollutant at low levels in the earth's atmosphere, causing harmful effects on the respiratory system and sensitive plants-can be reduced, on average, when electric vehicle charging is done at night time.

Ozone forms as hydrocarbons and nitrogen oxides, emitted into the air, react with sunlight. Two of the largest emitters of these pollutants are vehicles and electricity generating units (EGUs) with some of the most densely populated regions in the US still failing to meet the National Ambient Air Quality Standards after 30 years of regulation.
