MB joins Tesla’s Supercharging Network




I tried it at Tesla with my Lectron adaptor yesterday, it did not work, tried a few times with both Apps. Both Apps (Tesla and MB Me) showed error.
These could be a few reasons, will try a different location next time.




Does this apply if you are using the Tesla App? We bought a Lectron adapter last May. Installed the Mercedes over the air software that was sent to my husband's phone.
Went to local Tesla charging station and tried to charge using Tesla app. When he plugged in, he got flashing lights on the Mercedes plug in socket area and an "authentication error or try another charger" error on Mercedes screen in the car.
He is not positive he did all of the tasks with the Tesla App (select the individually numbered charger) before physically plugging in the charger (I should never have let him go try it without supervision. LOL!)

grabbed it at my local dealership in the LA metro area. It felt like the two parts folks thought about tacking on some markup but they went with $185.

I tried today at a different location, it worked for my 450+ with a Tesla App.
I haven't checked this to see if it works with my 450 SUV as yet. Both vehicles' PnC have been turned on in the Mercedes Me app. Not sure why it did not work as expected.
I will try this on the SUV sometime today and report back.
1. Parking was pretty simple at the location near me. Cord is short but as long as I back up it's pretty easy to reach.
2. MBUX sees the station but the numbering system was off . Vehicle read 1-8 but the stations were labeled 1a,-d,2a,-d so I had to count to reach the intended station I was using. The app sees the charge station numbers as they are.
3. I used the app to pay as it read the stations id correctly. Worked after the third time as it was very temperamental with the order in which it was done.
4. Identify station ID in app and then hit charge...afterwhich I plugged in charger to adapter and then to EQS.
5. Pretty seamless...

How do I charge my all-electric Mercedes-Benz using a Supercharger?
The Tesla Supercharger network is integrated into the Mercedes me Charge network, so ensure Mercedes me Charge service is active in the Mercedes-Benz app (Manage Digital Extras > Charging > Mercedes me Charge toggle switched to “Activated”). Next, confirm you have the adapter in the Mercedes-Benz app by toggling on the "NACS Adapter" under Charging Status & Settings. This will allow you to locate and route to Supercharger stations. At the station, you can start a charging session through your vehicle’s display or the Mercedes-Benz app. Connect the adapter to the cable, then insert the adapter into your vehicle and the session will begin momentarily. Please be aware that Tesla policy prohibits the use of third-party adapters that are not sold or distributed by an automaker.Last edited by Knick Fan; Feb 24, 2025 at 10:57 PM. Reason: added piece
I've used Tesla supercharger over 50-60 times and these new sites have failed 100% of my attempts, activation via Tesla app or Mercedes app/MBUX failed on handshake.
Locale : California, Oregon and Washington.
MBUX E504.
In the Tesla iPhone app:
1. Select a charger first.
2. Then press Start Charging.
Cabling and connecting
3. Remove the NACS connector/cable from the charger.
4. Connect the Vortex adapter to the NACS connector/cable
5. Plug the entire assembly into the car
In the Tesla iPhone app:
6. When charging is completed, press Stop Charging.
