Power Outage While Charging at Home

[tate16t]

Seems like the same recovery between the Rivian and Tesla chargers, and more importantly the vehicle itself.

Thanks again, really appreciate this.

My pleasure. Happen to have everything ready and handy to do the tests here Happy to help!

I honestly wasn't sure at the 2nd test with the adapter as that one sometimes acts up (you probably saw the first attempt to plug it in, showed a red light). So it was good to do this test for myself as well

Yeah, I remember when my flight instructor did basically the same thing in a Cessna 150 at 5,000 feet. Just cut the engine and said (deadpan) "oh, no! Engine failure! What do you do?" Talk about a hard reboot!

It’s an airplane, you have all day to react. Trim for 65ish kts and find a runway somewhere within 5 miles.

OK, this is what will happen when facing a power outage while charging your Rivian:



TL;DR: It will re-start your charging session after a few minutes. ?

As others have said - thank you for making the time to video this. It's good to know that the system works as I would have expected it to. Most days we're charging from 50% to 70%, but Murphy dictates that a power outage would occur the night before we need a 95% charge so it's good to know that I don't have to get out of bed and do anything.

That guy Murphy is always right ?

My Tesla wall connectors handle power outages pretty well. We live in a bit of a rural area so power can flip on/off sometimes.

IIRC our wall connectors will wait two minutes after power is restored before they attempt to restart the session.

Same for me
Restart when power returns

Just adding confirming datapoints - I've had outages with both my Tesla Wall Unit as well as the Rivian portable - both resulted in the Rivian reporting a charging error upon power interruption and then once power was restored, charging came back on without intervention.

That's about correct. You can watch that wait time on my video

Indeed, The only difference between the Tesla Wall Connector and the Rivian Wall Charger was that the later took 1 more minute to restart the charge. That's it

I wonder if the power was gone, but the breaker not tripped. This would be the case if the power itself from the grid was removed but the connection to that grid still connected. My question is hypotehitical because we cannot simulate this so we must wait and see,
I am however greatful for the clock and the accent and the video.

LOL! I would be too. Back in the 80's an internal IT auditor where I worked walked into one of our plant's computer rooms and asked how their disaster recovery plan was. Upon hearing that "It's good - we're solid" he walked over to the breaker and pulled the handle down! It was a IBM System-38 and they were down for over a week! As you said in your initial post, I'm sure it's been tested by the manufacturers, but I don't need to replicate that test.

I knew the S38 well…that shouldn’t have caused an issue. The little software company where I worked in the early 80s didn’t have power backup on our 38, and it took many power hits. Must have been their application software. ?

A bunch of our other sites ran S36's - they were straightforward batch processors and recovery would have been quick. The S38 was built around a database structure that was, in this case, broken when he pulled the plug so I think they had to rebuild everything from backups when it came back up. I'm sure you're right - it was our custom application stuff for running the production lines that caused the issues. Ah...the days of green-bar paper and 3" thick reports...

Yeah I did a lot on the S34 and S36 as well. The S38 had a. Integrated object oriented architecture and was intriguing but underpowered especially at first. Those were the days. I went on to the IBM 360/370 architecture machines in a university environment, first writing COBOL and then lots of 360/370 assembler for CICS and VTAM. VTAM apps were the most interesting. I wrote a lot of C along the way on networked office automation systems. Picked up a MSc in comp sci while I was working (hey it’s a university!) and I designed web-enabled student registration running in the mid-90s thru an old RS/6000 connected to IDMS on the mainframe. I wrote my thesis in 1994 on using the web for application development. But eventually if you understand both technology and people they make a manager out of you ?

Has anyone lost power to their home while charging their vehicle? I would imagine this is something Rivian and other EV manufacturers have tested. Anyone with real life experience?

Yes, we had a few short power outages during a storm and the truck just restarted charging after each drop out. No issues.

Thanks This can also be somewhat simulated by tripping the main breaker, though the result should be the same. These Wall Chargers have logic that needs a few mins of startup time in which case it won't (shouldn't) be able to differentiate a sudden lost of all power with a sudden return (tripping breaker) from a return of power from the grid (which might behave differently due to voltage variations as well as phase variations for a fraction of time.

I would not expect a different result from a real-life power outage
