According to new rules proposed by the Biden administration, electric vehicle charging stations built with federal dollars should be located along interstates every 50 miles, be able to charge cars quickly and be located no more than a mile from a major highway.

Pete Buttigieg said that EV drivers should be able to find a place to refill their batteries easily.

The proposed regulations are designed to ensure that rural areas and communities with few services have the same access to electric charging stations as more urbanized areas.

The goal of the Biden administration is to have half of all new vehicles sold in the US be electric by the year 2030.

Under the proposed new rule, states would be required to provide at least four of the fastest type of charging ports, known as Direct Current fast charging, at every charging station to allow multiple drivers to plug in at the same time.

Mr. Buttigieg said the plan will send a signal to companies that build charging stations that they should offer a standard facility that can accommodate all models of electric and zero-emissions cars. There are a lot of rest stops in the Northeast that have electric vehicle charging stations.

The bipartisan infrastructure law signed by President Biden gave the government $7.5 billion to build a network of electric vehicle charging stations.

The administration indicated in a notice of proposed rule-making that it would not allow charging stations built with federal dollars to require paid memberships. Real-time information about pricing and availability of ports can be found in mobile apps.

Electric cars are cheaper to operate than vehicles that burn gasoline, which is why the Biden administration believes electric vehicles are an answer to rising gas prices. Electric vehicles are being promoted as a way to reduce the country's dependence on foreign oil.

While sales of electric vehicles are robust, and many manufacturers have waiting lists for new vehicles, the initial sticker price is seen as a barrier to greater consumer acceptance.

The administration believes the charging station hurdle is going to be solved. Mr. Biden wants to build half a million charging stations by the year 2030.

The $7.5 billion in the infrastructure law was enough to meet Mr. Biden's goal, according to an administration official.

Motorists should be reassured that they will be able to charge wherever they are, according to Ms. Granholm.

She said that if we are going to build out infrastructure like we haven't done in a long time, we have to do it right.

It will be difficult for the Biden administration to make electric cars more affordable. Tax credits of up to $12,500 for consumers who buy electric vehicles are in limbo. Senator Joe Manchin III, Democrat of West Virginia, whose vote his party must secure to pass the measure, has called electric vehicle rebates "ludicrous."

In the United States, sales of electric vehicles have increased. Despite supply chain problems and Semiconductor shortages, sales of electric vehicles doubled last year and are on track to double again in 2022.

The G.O.P. believes that the Biden administration is tone deaf when it comes to the issue of electric cars. Republicans pounced when Mr. Buttigieg mentioned the savings on gasoline that can come from driving an electric car.
