Practically a 12 months in the past, GM started promoting an adapter to permit present electrical autos to make use of the North American Charging Normal plugs at Tesla Supercharger stalls. EV homeowners rejoiced of their newfound freedom.
Now, GM is asserting three extra adapters. The extra adapters, which assist GM clients entry EV chargers with totally different charging charges and requirements, is a win for flexibility, however at the price of simplicity. It’s totally attainable that two-EV households may personal 4 totally different adapters.
A number of years in the past, nearly all of EV fashions within the U.S. used the Mixed Charging System (CCS) normal. That’s, except Tesla. In 2022, the automaker opened up the design for its charging connector and cost port — which it now calls the North American Charging Normal (NACS) — in an effort to encourage community operators and automakers to undertake the know-how and assist make it the brand new normal in North America.
And so they did. Right now, almost all automakers are providing adapters to entry Tesla Supercharger stations. They’re even integrating the NACS design into their very own autos.
“GM has already dedicated to basically transitioning our entire EV portfolio over to NACS,” Tim Ash, director of {hardware} merchandise for GM Vitality, informed TechCrunch. “We imagine that shifting to that unified normal simplifies the expertise for our clients.”
However this shift has created an ungainly transition — and an abundance of adapters.
Along with the present NACS-to-CCS adapter for quick charging, GM will promote a NACS-to-J1772 adapter for Stage 2 charging. (J1772 is the a part of the CCS plug that handles slower charging speeds.) For future GM EVs which are constructed with NACS ports, the automaker will make a J1772-to-NACS adapter for Stage 2 charging and a CCS-to-NACS dongle for quick charging.

The brand new adapters “be sure EV drivers — no matter what charging kind they’ve on their car — can entry basically any charging wherever they want it,” Ash stated.
This drawback isn’t GM’s alone. Hyundai, for instance, sells NACS-equipped 2025 Ioniq 5 EVs with two adapters, one every for Stage 2 and quick charging at CCS-equipped chargers. However it’s a signal the transition between EV charging requirements will make public charging extra complicated earlier than it will get higher.
Now, for a majority of charging periods as we speak, the adapters are unlikely to sow confusion. Most EV charging happens at home or work, areas the place the chargers are going to be predictable.
However when charging at giant, it may get difficult shortly. Drivers ought to plan on stashing the adapters of their car so that they’re not left stranded or inconvenienced. For individuals with an incompatible charger at residence, they could wish to purchase duplicates for comfort. Too unhealthy most adapters price greater than $200.
Automakers aren’t totally in charge for the variety of adapters.
CCS and NACS are comparable sufficient that straightforward dongles suffice for every charging velocity, however they differ in necessary ways in which make simplification unlikely. With NACS, electrical energy passes via two giant pins no matter charging velocity. However with CCS, it passes via one set of pins for Stage 2 speeds and one other for quick charging. Merging Stage 2 and fast-charging functionality right into a single charger would doubtless require energy electronics that may elevate the value significantly.
Controversies over new plug requirements aren’t something new. Apple has offered iPhones with three totally different connector varieties, and the product hasn’t but celebrated its 20th birthday.
However the cadence in client electronics is far sooner than in automotive, and the prices are rather a lot decrease. The everyday smartphone proprietor pays $500 to $1,000 and buys a brand new machine every two to three years. Dongles price about $30. That 30-pin dock cable out of your 12-year-old iPhone 4? It’s lengthy forgotten.
The typical automobile or gentle truck isn’t so simply traded. Costs have soared to close $50,000 for a brand new car, a part of the explanation why the typical automobile or truck on the street within the U.S. is over 12 years old.
Automakers have began the transition, however they don’t look like dashing to complete it. To date, GM has introduced two EVs that may use the NACS charging normal: the 2026 Cadillac Optiq and the 2027 Chevrolet Bolt. The automaker hasn’t put a timeline on when it would migrate its remaining 12 EV fashions to the brand new normal.
In different phrases, get comfy with the dongles. The transition, Ash admitted, “will take a while.”
