Standardizing Adapters for the Transition from CCS to NACS J3400

Watch this video to get an overview of the benefits of standardizing adapters for the transition from CCS to NACS J3400. Specifically, SAE J3400/1 — Electric Vehicle Charging Adapter Safety and OEM Qualified Device Designation — which covers the physical, electrical, functional, and performance requirements for charging adapters.

00:00:01 it's finally happened we have multiple EVS without Tesla badges on the road with the SAE J 3400 Port there's the Lucid Gravity the second vehicle from the automotive startup and the company's first SUV outfitted with J 3400 also known as KNX then there's this the 2025 Hyundai ionic pipe outfitted with the SAE J 3400 Port it can charge it up to 250 7 Kow

00:00:32 but at a Tesla V3 supercharger which is pretty much all the superchargers out there it can only charge it up to 135 KW now you're probably wondering well if the car is capable of charging up to 257 Kow but at a Tesla station the version 3 supercharger it only charges 13 5 Kow really what is the point of adding SAE J 3400 to this vehicle well first off a lot of chargers will end up on the

00:01:09 market with SAE J 3400 and essentially all the charging networks out there will be supporting this uh Tesla has a version 4 charger that will support quicker charging with this vehicle and other vehicles but more importantly there is a way to charge at up to 257 KW with this vehicle right now now you can hit that 257 kilowatts of charging with this this is a j 3400 to CCS adapter

00:01:39 specifically this is Hyundai's j34 to CCS adapter and like the J 3400 Port this adapter is made possible thanks to standards and the standard for these adapters coming up is J 34001 and we're going to tell you why that slash one is so important this adap is from Hyundai and it does ship with this vehicle which is outfitted with J 3400 but if you have

00:02:05 say a Hyundai vehicle with a CCS Port um Hyundai will start sending you for free a ccs to J 3400 uh adapter so that you'll be able to charge your CCS enabled uh Hyundai at Tesla superchargers and future Chargers with the J 3400 plug automakers like Ford and Hyundai are sending out a adapters for CCS enabled Vehicles so they can charge at

00:02:34 Tesla supercharging networks now either they're sending them out for free or they're charging for them either way most of those automakers are also telling the owners of those EVS to only use the adapter that they send them do not use a third party and in some cases using a third party will actually violate your warranty and it's best to really heed the advice of those

00:02:57 automakers but it won't always be like this thanks to Saj 34001 the standard specifically targets adapters so that all adapters regardless of who is making them whether it be an automaker or a third party are safe to use so that all adapters have to meet specifications in order to alleviate any issues with the adapter itself regardless of what EV it is being

00:03:25 plugged into SAE is working to complement the Underwriters laboratory's UL 2252 testing criteria the UL 2252 adapter standard will indicate that a product has been effectively tested in other words it's safe for use with all EVS at issue is the amount of electricity going through these adapters and how they attach to these vehicles

00:03:52 any sort of resistance creates heat and when you're talking about up to 350 Kow being pushed to electric vehicles that has the potential for a lot of heat which means you end up with either melted adapters damage to the vehicle or potential for a fire this is especially important due to the millions of Legacy EVS on the road that will be around for decades as the

00:04:16 infrastructure transitions to J 3400 charging stations these owners will need an easy way to charge their vehicles regardless of the Native Port these owners might not have access to an automaker's adapter and they shouldn't have to to grit their teeth and hope for the best every time they plug in their EV buying a third-party adapter should be a worry-free experience and with

00:04:39 standardization that is possible
