EV charging at Tesla-session taken over by Rivian

[nellbarr]

Have never experienced this. It’s possible a glitch at Tesla’s end prematurely ended the session and caused plug and charge to initiate. Find out if it’s a fluke or repeatable behavior at a different site. If repeatable, contact Rivian support.

I have contacted Rivian-customer service does not seem to have a clue?

All three times at different Supercharger sites? Have you tried fast charging at other networks (that do not require use of an adapter)? The point is process of elimination, to narrow down and hone in on the possible culprit. Does it happen only at that one Supercharger site? Was the plug or adapter not fully seated? Is your adapter faulty?

happens at The Falls in Miami, different chargers. I had not noticed or tracked it previously. I have used EVGO, Electrify America, Chargepoint, and FPL-each have their own app and credit card that is not on Rivian and have had issues with charging stopping in the middle of a session HOWEVER, Rivian app/vehicle did not hijack the session. I had to disconnect and connect/start app again when it happened.

• Try a completely different Tesla Supercharger site.
• For Rivians, Supercharger and RAN are the only two networks that currently support plug-and-charge.
• Regardless of which credit card used, if you are able to charge successfully at native CCS1 fast chargers (like EVgo and EA), then you know it's almost certain that the issue isn't your Rivian.
• Each time, inspected and make sure all contact points on plug and adapter are clean. Upon assembly/insertion, make sure the plug and adapter are firmly and fully inserted and all latches are positively engaged. Brute force isn't necessary, just need to insert it like you mean it, swiftly. The only time I had my Supercharger session revert to plug-and-charge is when I second guessed myself, wiggled the plug+adapter before handshake—initiated through Tesla app/membership—was completed.
• With or without adapter, sessions at any DCFC can terminate prematurely if the dispenser and/or charger (built into your car) detect overheating or faults. Environmental conditions—low or high temps—can also trigger faults. The dispenser and your car both have their own sensors to monitor sessions. The Tesla-made NACS-CCS1 adapter may also have its own sensors as well (I know for sure the A2Z does).
• Try and test everything you can think of so you can provide Support with as much "data" as you can—to help them recognize and understand what could be the culprit.
• Lastly, whenever any error/failure occurs, long press your name in the center display will insert a flag into datalogs. If you contact Support and let them know that you flagged, they will have an easier time looking for it—and seeing what the car was doing/experiencing when the error occurred.

Quick question to make sure I understand this -- is the lower Tesla rate you should be getting because you have a Tesla membership? I chose not to do that yet as I don't currently do enough charging away from home to make it worthwhile. That may change this summer after I retire.

Or is it that ANY use of the Tesla app should get you a lower rate than Rivian? I assume its the former, as I have to start any session at Tesla with the Tesla app, correct?

Using the Tesla App because I have the membership. The Falls have 20 chargers so it's convenient to go there. I have not had that issue at the North Miami Beach/Target location. And since the other EV charging companies are not part of the Rivian/Tesla deal-have not had that issue with any other despite dropped charging sessions,

Without membership, Tesla bills non-Teslas around 20% more than what they bill Tesla owners. So, to enjoy the "discount" you must enroll and 1) initiate all sessions though the Tesla app, so the Tesla back end knows to bill you at the lower rate, and 2) you must charge there enough per each 30 day membership cycle to offset the $13 subscription fee; i.e. break even point. What that break even point depends on the per kWh rate, which varies at different locations and sometimes dependent on time of day (peak/off-peak). Generally, the rough math comes to 100-150 kWh, i.e. just one or two sessions pending your Rivian's pack size.

With membership, cost per kWh is on par with other networks' membership rates—give or take a few cents. The greater advantage is Supercharger's superior number of dispensers per site and reliability.

Any chance you are exceeding the membership limits? It only allows 5 charges a day at membership pricing.

no, I probably charge 6 x month

This can happen if the session stops and then restarts too. If you really want to prevent being billed at the non-member rate you can remove your CC from your Rivian profile. That will prevent successful charging session initiation via Rivian's plug-and-charge and the only way you will be able to charge at Tesla will be through the Tesla app.

Isn't Rivian supposed to be implementing support for Tesla membership? I thought I read somewhere they were working on that.

Talked about, but not implemented yet.

I tried that -removed the CC from Rivian since I could add it on if/when needed. HOWEVER, the Tesla app would not work then despite a CC on that app that was different. I had to add on the CC again with Rivian which then allows them to bill it when they HiJACK a session!

The point to remove cc from Rivian account has nothing to do with getting the session to work through Tesla, since the two aren’t sharing info. The point is to block Rivian/plug-and-charge from having successful connection, so you can eliminate that and restrict/narrow process to fewer variables. Again, standard troubleshooting logic: process of elimination. Reduce complications to hone-in on culprit from a smaller list of suspects.

Based on this it sounds like the session is not initiating with the Tesla app before plugging in the truck. The truck cannot initiate a session with a Tesla (via Rivian) charger if you have already initiated it successfully in the Tesla app.

you will know when it’s been successfully initiated by the Tesla app because the Tesla app will tell you to then plug it in.

here is a video of how to initiate the session on a Tesla charger.
