The Zhitong Finance App learned that the US Department of Transportation (USDOT) said on Tuesday that it has approved plans to build electric vehicle charging stations in all 50 states of Washington and Puerto Rico, which covers about 75,000 miles (120,700 km) of highways.

According to reports, in November of last year, the US Congress passed the $1 trillion infrastructure bill, of which 5 billion US dollars will be used to help states install electric vehicle charging stations along interstate highways within five years. However, after the US White House announced the approval of plans submitted by 35 states to build electric vehicle charging stations earlier this month, USDOT said that states can now receive more than 1.5 billion US dollars to help build electric vehicle charging stations.

USDOT's Federal Highway Administration did not immediately respond to requests for comment on how many charging stations the funding would support.

Additionally, USDOT said that government-funded electric vehicle charging stations must use DC Fast Chargers chargers. Charging stations should have at least four ports that can charge four electric vehicles at the same time, install electric vehicle charging infrastructure every 50 miles (80.5 km) on interstate highways, and be within 1 mile of the highway.

US federal funds will pay 80% of electric vehicle charging costs, and private or state funds will pay the rest.

According to information, US President Joe Biden has stated that he hopes 50% of all new cars sold in the US will be electric or plug-in hybrid models by 2030, and that 500,000 new electric vehicle charging stations will be built. But he has yet to support phasing out sales of new gasoline-powered cars by 2035.

However, the California Air Resources Board voted in August to require all new cars sold in the state by 2035 to be electric or plug-in hybrids. This landmark move may hasten the end of gasoline-powered cars, but it must still be approved by the US President to take effect.
