Charging stops within a few minutes with wall connector

[DrShah]

Maybe try reducing the requested charge current to less than 48A (32A?) and see if that changes anything?

Will do.

.....schedule a service appt.

Yes ?

 

[mongo]

Nope nothing for scheduled charging. Also whenever I plug in at work, it begins to charge immediately.

Scheduled charging is location dependent.
Any other profiles on the truck besides yours?

Yes - This could be it. Make sure there are no scheduled charge times. The CT might be shutting down charging because it is waiting for the scheduled time.

I would check if your connections to the breaker and the charger are torqued to spec. If they are loose charging will stop.

OP has two Wall Connectors and they both work with their Y, so probably not wiring.

depends on the Model Y. Aren't some of them limited to a max of 32 amps when A/C charging?

pretty sure that's a no....I have one of the first Ys (albeit the Performance) but I pull 48 amps from a 60amp breaker every night, same w my older 3 and the CT

The Model Y RWD with LFP batteries charge at 32 amps, I believe. And with the cold climate setting in, a very real chance the lugs need to be checked for torque.

Yeah, the 2023 Y RWD is only 32A, but we're still taking the situation where the both wall connectors have the same wiring issue that doesn't show up during a full 32A charge, but does in a couple minutes at 48A. Which *could* be the case if they are configured in load share mode and on the same circuit...

Load sharing does not stop charging on a wall connector all together but averages the combined load or sets it to your preferred load sharing setting (as set up through Tesla one app)

if truck charges fine at work but not at home, its a setting related to the location or home wiring. If the charge point/connector is blue, truck is waiting to charge (schedule). If there is a wiring issue, this could be a breaker or lose contact, it would most likely restore itself after temps come down. If the breaker trips, you would know it. So seems most likely a schedule problem (although if truck is hooked up outside schedule, it should not even start to charge hmm)

i would delete all schedules, notice that these can be set up for current location, home, work, independantly. Also set your charging current to 32a or even less just to see if a lower power setting can be sustained

Right, but load sharing allows multiple wall connectors to be fed from a single breaker in which case both WC could exhibit the same behavior. Whereas with individual branch circuits, it's unlikely to be a wiring issue.

no, that is a bad idea. Wall chargers must have their own breaker. Load sharing is accomplished by the chargers negotiating their needs via WiFi

That may be true with the Gen 3 wall connector. However, the universal wall connector has documentation for daisy chaining multiple universal wall connectors with one breaker. The lugs are different between the Gen 3 and the universal.
