General Motors Co. electric vehicle customers can now purchase a Tesla Inc. Supercharger adapter to give them access to the Texas-based EV maker's vast charging network, the Detroit automaker said Wednesday.

Customers driving a GM EV can purchase the GM-approved North American Charging Standard DC adapter through one of GM's brand mobile apps.

GM announced its charging partnership with Tesla in June 2023 after Ford Motor Co. said it would give its EV customers access to the Tesla network in an effort to help lower concerns about charging access. Automakers, including GM and Ford, have been using the Combined Charging System standard on their EVs, but Tesla's network is known to be more accessible and reliable.

Tesla has about 2,382 fast-charger stations with 27,390 charging ports in the United States, which is more than the 18,330 CCS-capable ports at 8,457 locations, according to data from the U.S. Department of Energy's Alternative Fuels Data Center.

The access to Tesla's network gives GM customers access to more than 231,800 public Level 2 and DC fast chargers in North America, GM said.

“GM’s ongoing efforts to help accelerate the expansion of public charging infrastructure is an integral part of our commitment to an all-electric future,” said Wade Sheffer, vice president of GM Energy, in a statement. “Enabling access to even more publicly available fast chargers represents yet another way GM is focused on further improving the customer experience and making the transition to electric more seamless.”

GM's NACS DC adapters, which are $225, will be made available first to U.S. customers, followed by availability for Canadian customers later this year. The automaker said it plans to use multiple suppliers to make its NACS DC adapters.

GM's announcement came the same day Ford Motor Co. and partners Honda Motor Co. and BMW AG said they began operations for their new joint venture, ChargeScape, a software platform that integrates electric vehicles with the power grid.

Through partnerships with utilities, the ChargeScape technology wirelessly connects to EVs to temporarily reduce demand when the grid is constrained.

Following the official launch of the joint venture, the companies named Joseph Vellone as the first CEO of ChargeScape.

Vellone, who has 15 years of experience in the energy and climate sectors, was recently part of the founding team at software start-up ev.energy.

The companies have also hired Kalidindi Raju as ChargeScape's chief technology officer. Raju has more than 15 years of experience leading high-performing technology organizations, including with Amazon.
