Any tests done on Vampire battery drain?

[NooterIA]

Same here, still losing 2-3 miles with the latest update. I notice there are little LED lights that stay on all the time inside the door handles, can't imagine those pull much juice but not sure what else would be on.. It's sitting in garage all night

I’ve been away for a couple days. I left my truck at 70%, with the EVSE set to charge at 24 amps (6kW; this amount works for us given solar production, Powerwall battery capacity, etc.) when it drops below. In 48 hours, the EVSE (which I can review remotely) has recorded 5.9 kWh provided, or 2.95 kWh per day. The EVSE shows a pattern of a draw every 4 hours or so, and looks very regular. This is about 2.3% (based on 130 kWh capacity) discounting the charging loss.

Gearguard disabled at home.

I’m looking forward to the 15% improvement in the drain

I’m still away, so the experiment continues…about 5 and a half days, 134 hours if I’m counting correctly, the EVSE has metered 17.1 kWh, so it’s been very constant, just under 3 kWh per day…I am one release behind (the most recent, promising a 15% improvement in Vampire drain)

2-3mi loss over 24hrs isn't terrible, but they (Rivian Engineering) can still do better if BMW, Nissan, VW, Chevy, etc.. can go 24hrs with virtually no loss.

Prior to the most recent software update when unlocked the LED lights in my exterior door handles would come on and go off at completely random times, sometimes staying on for hours. I assumed they activated when the truck was awake. Since the update that has stopped.

Over 9 days now very consistent 3 “ish” kWh per day loss. I don’t expect it to change over the next 10 days that I’m away. The ironic thing is that the vampire loss during this trip is enough to just about completely fill the battery in my 2020 Bolt On this 3 week trip
But I’m in France, and the wine is good….?

So I've been curious about this, .. Any ideas whether the air suspension is periodically recalibrating/adjusting height to compensate for any minute leaks over time (and potentially a source of power drain)? Or are there "clamps" to lock the suspension height to prevent that from happening when the powered off?

2-3mi loss over 24hrs isn't terrible, but they (Rivian Engineering) can still do better if BMW, Nissan, VW, Chevy, etc.. can go 24hrs with virtually no loss.

It's the architecture (essentially, a full computer rather than some OEM-specific microcontroller type solution) that leads to a lot of the power draw.

A data point. New truck first night in the garage unlocked with gear gaurd off at home, wifi connected, lost 0 miles and 0 percent, second night 1% and 3 miles. I'll keep an eye on it to see if things change tonight. But I wonder if other new owners can keep an eye on it for the first few nights and see if they find similar results.

I've been monitoring my vampire drain with homeassistant. I see about 6mi/day (~3kwh or 2%) loss every day.

I see the truck switching from "sleep" to "ready" power state roughly every hour.

I think there may be a problem with Gear Guard. It should be obvious when it is on in terms of battery drain, and instead it is consistent whether it is on or off. This is very different than, say, Sentry Mode.

The graph below shows this data. The sharp drop is from a short drive and short charge at a grocery store. You can see that the slope of the vampire drain is fairly consistent all along. After the drive I turned off gear guard and proximity locking completely, and there is no change, and curiously no change in the state reported to the API. The only obvious change is in the cadence of the power state changes, which I think is due to my phone occasionally connecting via BT before I turned off proximity unlock.

^ extremely helpful!

If Rivian can keep the truck from needlessly waking every hour 24X per day that may provide huge savings.

Another data point, truck parked overnight for 12 hours with gear guard and proximity off looses 3% consistently.

That's far beyond what it should be and Rivian can diagnose for you if you reach out to them.

I submitted one this morning after getting screenshots showing the drop. Hopefully they can pull the logs to see what is going on. I will update the thread once I get some more info.

It's very possible the loss isn't actually happening at the wakeup, but the metering of it to the API is.

You could do that…

Or you could buy a Lyriq, Mach-e, Lightning, Ionic 5, EV6, Bolt, Leaf, Aria… All of which actually turn off when you turn them off.

As much as I admire the Rivian’s capabilities, it’s becoming clear it’s more of a novelty vehicle part of the high efficiency environmentally conscious future that is needed.

I hope I don’t get the call before they decide what kind of future car company they really want to be.
