https://my.chevrolet.com/content/dam/gmownercenter/gmna/dynamic/manuals/2017/Chevrolet/BOLT EV/Owner's Manual.pdfI can't find this discussed anywhere. When you go on vacation without the car, is it best to leave the Bolt plugged in or unplugged?
The manual says to leave it unplugged with the 12v battery on trickle charge if it is not to be used for more than a month. I forget the exact wording. For a week away, leave it plugged in. I did the trickle charge thing for 6 weeks and had no problem. I would worry most about the 12 volt battery. As it ages it might go dead, in which case the car would have to be jump started. So, keeping it trickle charged makes sense for long periods of time.Just my info for this...
Just got back from a 2 week vacation.
When I got home from work before vacation, I had just under 50% left.
Car was going to be in the garage and no big temp swings, so I decided to just leave it unplugged.
Came back and the car was fine. Still just a bit under 50%. I'm sure I lost some, but not anything noticeable.
If I was going to be gone longer, I might have plugged it in (I use Hilltop, so it wouldn't have been left "full").
I read "down two or three bars" as "two or three bars away from a full charge". Perhaps the OP could clarify?Two or three bars sounds very low. I can see this if you are actually transporting the vehicle (less energy in battery if an accident happens) but why is such a low charge state recommend for long-ish term storage?
I believe the last comment is key: so it clearly depends on which charger you buy. Being somewhat of a boating person, I went for a not cheap waterproof charger designed for the rough and wet environment of a boat, which has all the protections required of a charger that is going to be left hooked up for long periods of time. It is also designed with built in digital algorithms to charge an AGM battery. The brand is Minn Kota; a small one rated at 5 amps. I also have a bigger dual 10 amp device of the same design that is permanently outside in all weathers, plugged in and charging boat deep cycle AGM batteries. For that setup I have the wiring and batteries under a dockside deck just in case excess water causes a problem. Of course, the Bolt was garaged while it was being maintained under trickle charge, with a garage temperature of 48F over the winter.Two or three bars sounds very low.
I agree with concerns about the trickle charger. ....... always make me nervous. In particular if the red wire gets a sharp tug and comes off the battery and shorts to ground you could have a real problem ......... chargers have short protection of some sort built in but .......... built as cheaply as possible...
Two sides to this: we always welcome converts, and boy what were your withdrawal symptoms thinking about someone else driving your beautiful Bolt!!I am overseas right now for work (3 months) and wondered what to do with my Bolt. I ended up lending it to a good friend who will drive it to work once a week (and charge there, if needed). He's German and loves his Mercedes S550 and the sound it makes. His biggest gripe about the Bolt (jokingly) is how silent it is when flooring it. I am trying to bring him to the dark side!
I do really miss driving my Bolt, but driving down here (Brazil) is kind of fun even though I have a crappy rental.Two sides to this: we always welcome converts, and boy what were your withdrawal symptoms thinking about someone else driving your beautiful Bolt!!

I think the concern about the 12V battery is with the all of the vampire drains on it.
This last trip, I followed the instructions to put the Bolt into "Transport Mode" and did not plug it in. When we returned, it powered up just fine, and the Bolt main battery was right where it was when we left. As far as I can tell, this mode turns off the vampire drains on the 12V battery.
We are wary of the trickle charger method, as we know someone that had a trickle charger on one of his cars for a long period of time and it caught fire and he lost his home.
Plus, this procedure is pretty simple:
