Supercharger FAIL
in my Ioniq 5

Recently Hyundai has started selling the refreshed 2025 Ioniq 5, which comes with a J3400 port instead of a CCS1. I saw a video by YouTube creator “Electric Principal” in which he drove one of these new models to a Supercharger site, plugged it in, and was able to charge it without any problem. This piqued my curiosity to know if I could also Supercharge using my A2Z Typhoon Pro adapter. To make a long story short… the answer is NO. Below are the specifics of my experiment.



NOTE: You can click on the following photos to enlarge them and the movie to play it.

I took my A2Z Typhoon adapter out of the frunk where I store all my charging paraphernalia.

If the experiment were successful, I wanted to charge Rocinante as fast as possible, which would require pre-conditioning the battery to the optimal temperature. The only way I could do that was by setting the navigation to take me to a CCS charging site, but then ignore the instructions and drive to our local Supercharger instead. Sure enough, when I arrived, I could see that the car had indeed warmed up the battery by the heating coil imposed over its icon.

The display for "Electricity Use" also revealed that Rocinante had used a whopping 5.2 kW to warm the battery en route, more than double the amount of energy it had taken to drive there.

I pulled into the first stall in the line of Superchargers sideways to better position my charging port without occupying other charging stalls and inconveniencing any Tesla owners. It was a handicap space, so I put up our handicap sign in the windshield.

Upon opening my Tesla app and selecting to charge my "other" EV, I could see that there were 10 unused chargers, and that I would need a J3400 port or adapter to plug in there.

Scrolling down, I could see a row of labels for the different chargers so that I could select the one for my stall.

I selected the one for "1A" where I was parked, and then pushed the button to "Start Charging."

The app told me that it might take two minutes to initiate the session, but instead of seeing Rocinante’s charging LEDs start to blink, they all lit up, shown in the following video. As you can see in this screenshot, the app then informed me that my “vehicle is not able to charge at Superchargers at this time." Phoooey.

This movie shows that neither the charging port LEDs nor the dashboard indicated that the experiment was successful.



But that’s not the end of the story. While I was there, I spotted a Kia EV6 owner at the other far end of the line of Superchargers. I drove down to see if he had managed to get a charge, and learned that… he had! He had used the same adapter that I have, but had re-identified his car as a 2024 Ioniq 5 —just like mine! Why he could manage to fool the network, but I couldn’t, is a mystery. It makes no sense. Whatever Tesla is doing blocks a legitimate 2024 Ioniq 5, but allows a “fake” one to charge successfully. Go figure!

By the way, in case you’re wondering, I then also tried re-identifying Rocinante to a 2025 Ioniq 5 to see if I could also fool the network. Nope. Still didn’t work. I guess I’ll just have to wait until older Ioniq 5 with adapters are given the green light for Superchargers —just like the 2025 models and that Kia EV6 with a bogus ID.
