The Biden administration is awarding $623 million in grants to help build an electric vehicle charging network across the nation.

Grants being announced Thursday will fund 47 EV charging stations and related projects in 22 states and Puerto Rico, including 7,500 EV charging ports, officials said.

“America led the arrival of the automotive era, and now we have a chance to lead the world in the EV revolution — securing jobs, savings and benefits for Americans in the process,” said Transportation Secretary Pete Buttigieg. The new funding “will help ensure that EV chargers are accessible, reliable and convenient for American drivers, while creating jobs in charger manufacturing, installation and maintenance for American workers.”

Congress approved $7.5 billion in the 2021 infrastructure law to meet President Joe Biden's goal of building out a national network of 500,000 publicly available chargers by 2030. The charging ports are a key part of Biden's effort to encourage drivers to move away from gasoline-powered cars and trucks that contribute to global warming.

But progress on the network has been slow. Ohio and New York are the only states that have opened charging stations under the National Electric Vehicle Infrastructure program. Several other states, including Pennsylvania and Maine, have broken ground on federally funded projects and are expected to open stations early this year. A total of 28 states, plus Puerto Rico, have either awarded contracts to build chargers or have accepted bids to do so.

Since Biden took office in 2021, EV sales have more than quadrupled and reached more than 1 million last year. The number of publicly available charging ports has grown by nearly 70% to 168,426, White House climate adviser Ali Zaidi said.

That number is about one-third of the way to Biden's goal, with six years remaining.

“We are on an accelerating trajectory to meet and exceed the president’s goal to hit 500,000 chargers and build that nationwide backbone,'' Zaidi told reporters Wednesday.

Widespread availability of chargers is crucial to meet another Biden administration goal: ensuring that EVs make up half of all new car sales by 2030. Along with cost, “range anxiety” about a lack of available charging stations is a key impediment to buying an EV. About 80% of respondents cited concerns about a lack of charging stations as a reason not to purchase an electric vehicle, according to an April survey from The Associated Press-NORC Center for Public Affairs Research and the Energy Policy Institute at the University of Chicago.

Seven in 10 respondents said they would not purchase an EV because they take too long to charge and the battery technology isn’t ready.
