NACS

As GM prepares to switch its EVs to NACS, it has some new adapters

The first adapter that GM released, which cost $225, allowed CCS1-equipped EVs to connect to a NACS charger. But now, GM will have a range of adapters so that any of its EV customers can charge anywhere, as long as they have the right dongle.

For existing GM EVs with CCS1, there is a GM NACS DC adapter, just for fast charging. And for level 2 (AC) charging, there’s a GM NACS level 2 adapter.

For the NACS-equipped GM EVs (which, again, have yet to hit the showrooms), there’s a GM CCS1 DC adapter that will let those EVs use existing non-Tesla DC charging infrastructure, like Electrify America’s 350 kW chargers. There is also a GM J1772 AC adapter, which will let a GM NACS EV slow-charge from the ubiquitous J1772 port. And a pair of adapters will be compatible with GM’s Energy Powershift home charger, which lets an EV use its battery to power the house if necessary, also known as vehicle-to-home or V2H.

Although we don’t have exact prices for each adapter, GM told Ars the range costs between $67 and $195.

Hyundai’s NACS adapter for EVs will be free to all existing owners

Hyundai Ioniq 5s with NACS (J3400) ports, as opposed to the CCS1 style, are starting to roll out of its factory in Savannah, Georgia. It’s the first manufacturer to sell electric vehicles with native NACS ports—other than Tesla, that is, and you’ll be able to read about our first drive in the model year 2025 Ioniq 5, as well as the new, off-roady Ioniq 5 XRT next week. But we’ve got some good news for owners of any existing Hyundai EVs out there—if your car has a CCS1 port, then next month, you’re eligible for a free CCS1-NACS adapter.

Hyundai wasn’t the first OEM to ink a deal with Tesla to gain access to the Supercharger network, but it is ahead of Ford, General Motors, and Rivian in swapping to the Tesla-style charge ports. Existing owners get access to the large charging network, too, but they’ll need an adapter to make use of the smaller NACS plugs.

And those will be available next month, Hyundai told us. What’s more, they’re going to be gratis, or free as in beer. As long as you have a VIN, the automaker will send you the adapter, which you’ll be able to order once the website goes live in March.

Ford briefly showed similar generosity to its EV owners last year, offering its NACS adapters for free—at least until late June, at which point it started charging $200 for them. GM never even bothered with the free giveaway; instead it asks $225 for the NACS adapter.
