President Biden visited the Detroit Auto Show Wednesday, using the backdrop to announce $900 million in grants for electric vehicle charging systems distributed to 35 states. The grants from the initial investment in what will become $5 billion allocated as part of last November’s bipartisan infrastructure law.

“You are going to be part of a network of 500,000 charging stations,” Biden said a crowd of union workers at the show. “The great American road trip is going to be fully electrified whether you’re driving along the coast, or on I-75 here in Michigan.”

Upgrading the country’s charging network is critical to Biden’s national goal for electric vehicles to make up 50% of all vehicles sold in the United States by 2030. Per the terms of the next round of EV tax credit in the Inflation Reduction Act, the White House and Congress are attempting to make both new and used EVs affordable, as well as bolstering the auto industry generally.
