So today I decided to see how low I could take the Bolt on charge. I started out this morning with 28% SOC on the My Chevrolet app with 80 miles of range left.
I had driven 175 miles at that point starting out with 87% charge.
I ended with 2% SOC on the my Chevrolet app and 6.8 miles of remaining range. The GOM started reading low at 16 miles of range remaining, so I checked with the My Chevrolet app and it was still indicating SOC at 4%.
Reduced power came on at around 3% SOC.
The Car shows I went a total of 248 miles on 54.6kWh, including 7% climate control use. Again Starting SOC was 87%.
I am now checking to see how long it will take to charge from 2% to 100% on my Chargepoint Home Flex level 2 charger at 7.54kW charging rate. The my Chevrolet app says 10 hours.

So that 67.67 kWh is from the wall? 7.6 kW in, is 7.2 kW out to the battery, or 94.7% efficient onboard charger. A bit of what leaves the onboard charge is lost to internal impedance in the battery too. So your new battery is about 64 kWh...just like the LG label says.

That’s how my math works out too.
In fact I checked it also at 87%
here is what it showed then. 2% to 87%

At current gas prices ($4/gal), that pencils out to nearly 150 mi/gal.

Woot!

$4.34 here..

I was down in San Francisco last week and prices were in the $6.xx range. I felt it because we were in my camper van. It's the first time I've had fill-ups costing over Cdn$100...
They had a sign for cash $4.17 today. Figured I'd better fill up before it got worse. Turns out they didn't reprogram the pump. Felt like I stole it at $4.04. Still $83 for a fill up on truck.
Speaking of low range...

Does anyone have a link to a video of a Bolt being driven until the battery is completely dead?

This video is close...but he managed to park before the battery died. I'm just curious to see how the car behaves at the very end when it shuts off.

I hope to never find out, but it was nerve raking watching the video you linked. Good to know it can probably do about 12 miles after the low battery comes one, depending on throttle usage of course.
According to the Owner's Manual, there is a final message just before the car shuts down...

When the battery is fully depleted, the OUT OF ENERGY, CHARGE VEHICLE NOW message will display and the vehicle will slow to a stop. The brake and steering assist will still function.
I was just wondering if anyone had taken a video to this point.

Over $6 a gallon for gas here in Eureka, a penny under $7 for diesel.

In this one he drove it until there was no more power.

Thanks for posting that video. That's what I was looking for. So the car just doesn't shut down at the very end. It looks like once you get this message...

...you have about 1 minute to pull the car over (with 1kW of power) before it shuts down.

My BMW would act like it hit a deer and slow from 55 or so down to 10 while alarms and lights. Really scary.

One think I notice about the Bolt is that when I do power off and exit the car, it seems like the power steering is still active. Assume it is a safety issue to have it working still.

It's pushing towards $7 around me (coastal So. CA). I was using the national average.

Up here on the Lost Coast diesel is $7+. Gasoline isn't far behind.
