Breaker tripping - no SMS notification.

[wwheelkid]

I am charging at home and using a 50 amp breaker. The truck is pulling about 8.4 kW. However, the breaker keeps tripping and I don't realize it as I am not getting any notification from the Rivian app.

What do you think is causing the breaker to trip? I have asked to get this replaced but worried that it may not been the entire problem. When charging I do hear a sound coming from the breaker - sizzling and popping - however very subtle. The breaker is warm but not overly so.

Can you get the app to notify you when charging stops before the desired percentage. Allow notifications has been selected as well as SMS Order notifications, if that matters.

Thanks for your help.

You need an electrician.

To start troubleshooting, try turning down the amperage and see if that helps.

Otherwise you'll need to inspect the wiring connections and such.

There is a ton of amperage flowing through the wiring, so don't mess around! The breaker is flipping for your protection

The guideline is that you should run a continuous load (like EV charging) at 80% max of the circuit's rated capacity to avoid damage to the circuit. So you should charge at a max of 40 amps to be safe (Rivian default is 48 amps).

Luckily Rivian let's you dial down the charge rate settings on the truck.

As other are saying try dialing back the draw, maybe 32 or 24 amps just to see but sounds like it might be a bad breaker I would have an electrician come sooner than later to check the circuit. A 50 amp circuit should only pull max of 40 amps.

Notes say the next OTA should alert when charging is interrupted.

8.4 kW is about 35A at 240V, so your 50A breaker should handle a sustained 35A. If it’s tripping something is wrong.

Like others have mentioned try 32A and have an electrician check the circuit out.

What have you set up in the truck ?

I am not an electrician so can only tell you my own situation which seems similar.

When I set up my panel+breaker+wiring I was unable to convince the electrician to put in a NON GFCI breaker. I know that complicates things when the breaker AND the charger AND the truck all have GFCI built in. My breaker would trip constantly (although not everytime) until I turned down the charging amps in the truck to 39 AMPS ( I have a 50 amp GFCI breaker).

Now it trips occasionaly maybe one every 20 charges between our T and S

Not an electrician, but if you are hearing sizzling and popping sound from the breaker, and also tripping, that’s most likely the culprit. Have an electrician check and replace it.

Probably a loose connection at the breaker, the screws may not have been torqued properly. Get an electrician to look at it.

 

[Smeek]

probably should stop using it until an electrician looks at it.

My charger occasionally trips as well, though it has been 90% of the time when my wife's R1S is plugged in. My R1T trips the breaker maybe 1:50 charges. I have a 60a breaker and charge my R1T at 48a. Ive turned down my wife's R1S to 32a. Seems to help with her car tripping the circuit.

I've come to believe there is something faulty with her R1S's charging hardware. Highly doubt if I took the vehicle in they would be able to find anything wrong with it. Murphy's law dictates it would charge normally the one time they tried to replictate. Oh and when it does trip it is almost exclusively at the very beginning of a charge session.

Electrical/control systems engineer here. Here's my checklist for you, more info would be helpful:
- What brand EVSE (aka charger)?
- What is the max amperage rating?
- Was it configured properly for it's installed max rating (80% of circuit rating)
- Is the breaker a GFI breaker?
- Does the EVSE have an internal GFI? If so, dual GFI installations can be fine, or be problematic.
- Is it hardwired or using a NEMA 14-50 4 prong plug?
- Is the vehicle charge rate set at or below the EVSE max?
- Brand new circuit breakers can be defective and trip below the rating, it's not uncommon.
- Existing breakers that worked fine may never have been stressed at near full rating and will fail.
- Loose connections can cause trips. Tighten connections at the panel and receptacle or EVSE.

do not use the breaker with the pigtail white ground I had the same problem
switched out the breaker for a regular one "not ground default GFCI breaker" and works perfect

the Rivian wall charger already has that built in

Sounds like a bad breaker/connection.

With the next update you will get notification of change(s) in charging. Not sure if this is APP update also requires a vehicle update?

“Also, on all mobile app versions, a push notification appears when either of the following occurs:

A charge session at any charge is interrupted unexpectedly and stops.
A charger is plugged in but isn’t charging because the cable isn’t properly latched.”

When charging I do hear a sound coming from the breaker - sizzling and popping

I'm not an electrician, but

The release notes for the next app version should notify you. In .42

This aside you need to fix the trip. Major hazard
