General Motors announced September 18 that it has now officially opened up access to more than 17,800 Tesla Superchargers for its customers, with the use of GM approved NACS DC adapters.
With the addition of the Tesla Supercharger Network, GM customers will have access to more than 231,800 public Level 2 and DC fast chargers in North America, GM announced. GM approved NACS DC adapters will first be made available to customers in the United States, followed by availability for Canadian customers later this year.
“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 news release. “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.”
Based on previous reporting, EV Rider expects that the adapters will work at V3 (version 3) and newer Supercharger stations. Older Tesla Superchargers that haven’t been updated yet to the newer equipment are likely to remain incompabile with non-Teslas.
GM and other non-Tesla EV owners should also be aware that many Superchargers have very short cords that will likely require non-Tesla EVs to take up 2 or more spots to position their EVs close enough to plug in.
To access the Tesla Supercharger Network, U.S. customers will be able to purchase a GM approved NACS DC adapter through GM vehicle brand mobile apps for an MSRP of $225. Customers will be able to also use the same apps to locate available Tesla Superchargers, check station status, initiate a charge, and pay for charging sessions.
GM plans on leveraging multiple suppliers to produce approved NACS DC adapters. At the time of this story’s posting GM had not released a list of approved vendors. EV Rider recently reviewed a Lectron adapter at a Tesla Supercharger, which worked as expected on a Ford Mustang Mach-E.
EV Rider has also reviewed a NACS to J-1772 adapter (see second half of story & video) that non-Tesla owners can use at Tesla Level 2 Destination chargers.
