Yes, but not when Supercharging.Doesn't the onboard charger convert AC to DC?
I was responding to this incorrect statement.Yes, but not when Supercharging.
But that whole post was talking about Supercharging, the subject of this thread. And for that the on-board charger does not participate in the AC to DC conversion.I was responding to this incorrect statement.

The Supercharging Station converts AC to DC from the grid. But the On board charge is what coordinates the dance of circuits leading to the supercharge powering the car for DC fast charging.I was responding to this incorrect statement.

Albeit the onboard charger doesn‘t participate in the conversion of AC to DC, but it coordinates how this power gets to the battery from the charge port.
I'm pretty sure that even back in the days when there was a separate HVJB, it was essentially dumb, and the "charger" took care of all of the Supercharging communications and telling the HVJB what to do. I think that functionality has now been split out into a separate module, the "charge port ECU" on the 3/Y.I think some of this talking past each other is because of how the modularity of the parts have shifted over the years from the S/X to the 3/Y. The high voltage junction box used to be a separate physical part within the car that detected a DC connection and routed it into the battery instead of going to the "charger". The "charger" was a separate piece that really wasn't involved.
Replacement of what exactly? The hvjb? Why didn’t the service center do this for me when I took it in? Seems to only be able to supercharge at the lowest amps possible.Buy a replacement from wk057 and be done with it. I couldn’t supercharge but could AC charge. They shipped me a replacement at a reasonable cost and I sold the old one on ebay. Problem solved.
It was the fast charge contractor for the high voltage battery. Parts 70 and 2.5 hours labor. I hope this helps somebody else diagnosing their car. Charges fine now. Thanks a lot for our heroes at the service center keeping our cars rolling. Cheers everybody.Replacement of what exactly? The hvjb? Why didn’t the service center do this for me when I took it in?

I know this is a very old thread, but in the spirit of not starting a new thread, I wanted to add to this.After taking a short road trip out of the metroplex yesterday in my Model S, I stopped at the Southlake, TX supercharger to charge for the final leg home. The supercharging began, as normal, drawing about 90 kW. After a few minutes, however, the main display switched to "Charging Stopped." Plugging and unplugging and switching stalls didn't help. Each time I plugged in and car would display "Charging will begin momentarily," for a few minutes, and then switch to "Charging Stopped."
Since then, I've charged successfully at two wall chargers but supercharging still doesn't work, even when trying at the Plano supercharger. (The only difference was that while at the Plano supercharger the instrument display periodically displayed a message saying "Cannot charge. Unplug and try again.")
I spent nearly an hour on the phone with roadside assistance while at the Southlake supercharger and the technical people who dug into the issue were unable to identify a cause. We've scheduled a service appointment for Wednesday but I wanted to see if anyone had any ideas in the meantime.
Exactly the same issue here on my 2023 Model Y Long Range. I was at 15% at a supercharger 100 miles from home and it would not charge. Worked fine the day before. Same symptoms as on this thread - not an issue with the supercharger itself and no amount of rebooting my car or trying different chargers helped. Luckily I was able to find an L2 charger and get home (L2 works fine), however I now need to wait over a week before Tesla can look at it. The Tesla phone reps were useless. I rely on supercharging on longer drives and using L2 is not going to work for me (can't make a 5 L2 hour charging stop on the way). Just curious how long ti took to resolve your issue and what the diagnosis was.I know this is a very old thread, but in the spirit of not starting a new thread, I wanted to add to this.
My 2023 MYLR now has the same problem - will not DC charge from a Supercharger or any third party DCFC (with Tesla adapter).
The Supercharging session seems to start normally, but about 2 to 5 minutes in, it will fail and stop with the message “Charging Stopped”. No error messages displayed in the car from the bell icon. Moving to a different stall, same outcome.
Almost got stranded out of state near the end of a 3500 mile trip. The couple dozen SC sessions prior to that were totally normal; just randomly stopped working at Liberty MO and cannot DCFC charge anywhere now.
AC is fine at home or anywhere on the road with J adapter. It just took a long time to get enough juice from Chargepoint L2 to get home.
It was charging for just a few minutes which is why this image shows 7kw added before it failed. None of the other stalls were successful after that. This image was another failed attempt further up the road in St Joseph MO. (Edit: it looks like these images are not uploading)
I get the sense from this thread that S/X and 3/Y are just a little different, but anyone have this issue recently with a Y under warranty and what was the fix?
Soonest the Service Center can take me is a couple weeks from now.
Thanks in advance
That is concerning. Now I will worry a little bit every time I go on a road trip. Have you scheduled service? Do let us know what comes of it please.Exactly the same issue here on my 2023 Model Y Long Range. I was at 15% at a supercharger 100 miles from home and it would not charge.

I had this issue in 2018 in my brand new MS 90D. See post #17That is concerning. Now I will worry a little bit every time I go on a road trip. Have you scheduled service? Do let us know what comes of it please.
Has everything been good since they replaced the defective part(s) in 2018? Just wondering if this is a problematic component or just a one off.I had this issue in 2018 in my brand new MS 90D. See post #17
Tesla replaced my defective onboard charger to resolve the issue.

I haven’t read all responses. I literally had this exact issue with my previous Model S 90D while out of town on my first road trip in the first week of ownership last year. I had to use ChargePoint and a 110 outlet to get home. They replaced the onboard 72amp Charger and all was good. At the time it was explained to me that even though supercharging is DC and bypasses the actual AC to DC onboard charger, The circuitry on the charger does provide power management during supercharging. I can only assume this is somehow independent from the power management for AC to DC charging, since it also worked in my case.
Dang...that's worrisome. Replacing an entire $3000 onboard charger for a supercharger issue? The supercharger basically bypasses the onboard charger, so I'm wondering what actually failed...a $50 relay?I had this issue in 2018 in my brand new MS 90D. See post #17
