Tesla adds General Motors to growing list of companies that will use its Superchargers

• GM cars will be able to use Tesla's Supercharger network.
• Ford and Tesla announced a similar partnership announcement in May.

General Motors vehicles will soon be able to charge at a large swath of Tesla's vast Supercharger network starting in 2024, the two companies announced Thursday.

GM vehicles will have access to 12,000 Superchargers next year, the company said, with the automaker adopting the North American Charging Standard (NACS) in 2025. It effectively doubles the number of chargers GM drivers have access to, CEO Mary Barra said.

It's part of a growing cooperation between Elon Musk and legacy automakers that will help bring them all to "equal footing" when it comes to charging, easily one of the biggest hurdles to mass EV adoption in the United States. Having most, if not all, automakers on one charging standard — with a universal connector — could be huge for driving sales.

"Consumers won't have to worry about what plug, what socket, which charging station," Tesla CEO Elon Musk said. "This is a huge advancement for electric vehicles in North America."

Tesla announced a similar partnership with Ford in May. Tesla has also opened parts of its European charging network to other cars.

Tesla has more than 20,700 Supercharger plugs in North America, according to the Department of Energy, making it easily the largest charging network. While other stations struggle to keep chargers working and online, Tesla's are known for reliability — and the huge network is a massive selling point for its cars.

Shares of GM jumped nearly 4% in late trading Thursday following the announcement.
