Mentioned in other threads but at least on the 2019, you can force battery heating (assuming battery is cold) by setting the target charge level below the actual state of charge and then plugging in - at least on level 2. The battery will precondition until it reaches around 60 degrees F (the coolant will get to 82 degrees). If preconditioning via the key fob in low temperatures, you can't always get to 60 degrees in the twenty/fourty minutes allotted.

At noon yesterday the app for my 2022 Bolt EV (parked outside) showed 84% charge and 176 miles of range. Overnight the temperature dropped to minus 8 degrees F. This morning I have 82% charge, 170 miles of range and 9 degrees. There was obviously some conditioning going on to protect the battery. The car was not plugged overnight. Don't ask me to go out and check the car's screen because that's not going to happen. It's cold out there! :D

Poor little Bolt....:cry:
Is there reason you are not following the Owner's Manual recommendations?
You are not doing your pack any favors, but you may be saving about a dollar.

It's a lease with the original battery and I don't feel safe leaving it plugged in overnight. If the battery had been replaced, I would have left it plugged it as recommended.

Software update fixes plugged in issue.
Although, the battery is going to be replaced soon under the recall, so it hardly matters if leaving it unplugged in such cold temperatures shortens it's life a bit.

I started plugging in mine with the factory charger since seeing this thread. I set the charge level in the car below the batteries current SOC and leave it plugged in on the 120 Volt outlet. I see that while doing the conditioning on my inverter, it pulls one kW when active. This works perfect for me as it is using my backup battery packs at night to keep the battery warmer than the outside air temp. I have 36 kWh of battery backup, so, not a big deal.

This really is a simple work around being 100% off grid. I have my L2 charger when the suns producing during the day and run the 120 setup just for conditioning at night not to drain my system at night.

Now that I think about it, I could use the L2 the same way because I can just control it by turning the charge level below the battery SOC just like using the 120 volt charger. Duh! :p

I keep my EUV plugged in overnight every night for battery conditioning. I use a Chargepoint Home Flex smart charger, so I can see the graph of current over time. Every time the battery heater turns on, it spikes about 3 kW. Depending on how cold it is, it will do it multiple times during the night.

Oops, right. I forgot about that possibility.
I had those rules with mine for a while.

@jreddington I'm not sure that will work with the Bolt. It's worth a shot to verify.
Not sure when I would ever really need it. If I leaving home I鈥檓 at 80% charge. I鈥檓 not looking for a DCFC. On a road trip, a couple hours of regular driving will do some battery warming. On a road trip I probably don鈥檛 want to purposely reduce my range.

And there is the issue about how you鈥檙e treating your battery.

But a fascinating experiment will dramatic results.

I read in an article that the Bolt doesn't warm the batteries when its turned off.

Does anyone know if they get warmed when you remote start the car using the dongle or app?

Its gonna get below 0F here and my Bolt is inside an unheated garage, plugged in. Wondering if I should remote start it for 20 mins at all to keep the batteries from getting too cold too long ...

thoughts? thanks ..
My 2019. Have the features if is park, on or off and fewer times wen I鈥檓 driving. Depending of the conditions
