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.

• Lack of charging access is one of the biggest hurdles to EV adoption right now.

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.
