Turning off My Wall Charger

[Fmc]

I am out of town and ran a little experiment. My charger uses roughly 6kwh per day. I am throwing away $200/year. Other than using my breaker box, is there a way to power off my Rivian Charger? Also if not does anyone have a charger that powers down?

Your wall connector was using 6kwh per day while not connected to anything? That's 250w to do nothing. Something seems amiss. How did you come to this conclusion? There is really nothing for the connector to do while no vehicle is plugged in.

When away my house historically uses 12-14kwh per day..I flipped the breaker on the charger and now my house uses 6 kWh. Yes this is unscientific.

Is someone helping themselves to your charger? It should use a few watts at most. Otherwise you've got a serious short in your wiring somewhere.

Over a month, if your unplugged charger uses more than 2 or 3 kWh, something is very wrong. That would be 67 to 100 WATTS per day.

As folks have mentioned, if you really are seeing that much power consumption with your idle charger, you have a real issue.

I would turn it off and call an electrician ASAP.

That or your experiment is way off.

I'm wondering if there is something else on that breaker.

Also curious to see how the 12-14kWh/day is measured. Meter reads? Monitoring tech? Provider website?

I ordered one like this just to try.

I think the problem with the way you are testing is that the HVAC cycling can skew the findings. You can measure the current with a clamp-on meter, if you can get access to the wires. You said it is a rivian EVSE, so it is hard-wired. Tougher to measure with a multimeter since it has to be in-series with the wires.

I am following this thread because I have a similar problem. My smart panel shows my 2022 r1t using 4-5 kWh per day in my garage. No gearguard on and no climate control. The rivian charger is on a dedicated 240v breaker. I called service and they said try a hard reset but I can’t do that remotely. Anyone have a solution to this vampire drain? I can turn the breaker off remotely (and did) but the drain continues.

... if that's the case, that's probably a broken Wall Connector. That's a LOT of energy for an idling charger. I can measure mine in a bit but with my Battery/Inverter setup, my entire house consumes 600w when I'm away and that includes everything that it's plugged in idling (TVs, computers, Microwave, etc), plus my pFsense router (~70w), home lab/home assistant hypervisor (~120w), Home alarms, sensors, etc,etc..

No it doesn't.

Did you try checking Rivian about how much energy the charger is supposed to use while idle? They might know the issue if it is using way more power than it should.

okey, I just ran some quick test.

I'm assuming your vehicle is NOT plugged into your Rivian Wall Charger. Right? If it is, then it might consume some (easiest way to avoid it, would be to set a Charging Schedule from the app with the minimum possible time and also lower the charging limit to below the current SoC of the Battery). Also, if it is plugged in, make sure you don't have any Climate Schedule set up that might pull power from the grid.

Having said that, I just turned off both my Rivian and Tesla Wall Chargers (for good measure) and the change in my whole-house wattage was ZERO or something so small I couldn't measure). I was clocking 976w before and after disconnecting the breakers.

So if you have that idle consumption w/o a vehicle plugged in, something is very very wrong

I just had this same thought as well. Wonder if it's still plugged into the truck with a daily climate schedule set.

Mine warmed from 32deg to 68deg in the driveway this morning and used 2.4kWh according to the energy page in the dash. If it's doing that a few times a day it might explain the power draw?!?!
