US President Joe Biden’s administration has released an ambitious federal strategy to build 500,000 charging stations for electric vehicles across the country and bring down the cost of electric cars with the goal of transforming the US car industry.

“The future of transportation in our nation and around the world is electric,” Vice President Kamala Harris said at an EV charging facility in suburban Maryland.

The $US1 trillion ($A1.4 trillion) infrastructure law Biden signed last month authorises a country-wide network of charging stations and sets aside $US5 billion for states to build them, including $US63 million for Maryland.

The law also provides an additional $US2.5 billion for local grants to support charging stations in rural areas and in disadvantaged communities.

Biden’s $US2 trillion social and environmental policy bill, now pending in the Senate, includes a $US7500 tax credit to lower the cost of electric vehicles.

The administration wants “to make electric vehicles accessible for everyone,” Harris said.

“Absolutely make it accessible for everyone and easy. Just like filling up your car with gas.”

Harris visited a maintenance facility in Brandywine, just outside Washington DC, where she received a demonstration of how chargers work and learned about a plan to electrify the government fleet in Maryland’s Prince George’s County.

“There’s no sound or fume!” Harris exclaimed as a local worker demonstrated the charger.

“How do I know it’s actually working?”

The car is fully charged when it’s blinking green, the worker told her.

Accelerated adoption of electric vehicles for personal cars and commercial fleets would help achieve Biden’s goal of net-zero greenhouse gas emission by 2050 while creating thousands of jobs, the White House said.

The effort also is intended to help the US leapfrog China in the plug-in EV market.

Currently, the US market share of plug-in electric vehicle sales is one-third the size of the Chinese EV market.

Biden has set a goal that electric cars and trucks account for half of new vehicles sold by 2030.
