Re: Main USB ports (connected to main screen) Failure

I suspect this is a very specific Chevy thing and the dealer might be your best bet. I would try to reset the system (home +fastforward) and if that didn't work, disconnect the negative terminal of the 12V battery for a few seconds, then reconnect. If none of that works....dealer time. Edit: You mig...

Re: RECALL

Apologies if this has been discussed already. Might it be possible that the battery temperature sensor module fails in a way that always indicates that the battery is too cold? This would turn the battery heater on, and leave it on no matter how hot the battery got. Could this induce thermal runawa...

Re: Charging/Range

The fly in the ointment is your charging situation. At 120V and 12 amps, you'll be charging around 1kW which will give you around 4 miles added range per hour of charging. Not enough for your 146 mile round trip. You can find chargers near you (or along your commuting route) by looking at plugshare ...

Re: Software Update For Range

The software update shouldn't change your actual range. Remember the GOM is an estimate and will go up and down depending on a lot of factors. It looks like it might have affected charge time, though. https://www.chevybolt.org/threads/new-charging-curves-on-2018-bolt-ev-after-final-recall-update.388...

Re: Driving in L uses More Energy?

Short answer, no, I have not experienced this. Longer answer: I can't really comment on why you didn't get regen while "going to the store" and driving in L. Regen depends on how you modulate the accelerator and the terrain. Also, your miles per kWh depend on a lot of things. Regen is one ...

Re: Real life winter "stuck in traffic" numbers

The Bolt's heater uses at most 7kW to get the car warm, then maybe half that to keep it that way. So if it uses 4 kW and you have a 50% charge (30kWh) you could keep the heat on for about 7 hours. I'm not sure a gasoline car would last that long, but in any event you'll be fine. However, it is a goo...

Yes.
The 5 amp setting will increase charging time by a factor of 2.4 vs the 12 amp setting.

Re: Did I do Any Damage?

I think you're fine. That grinding sound you heard was probably the parking brake being applied.

Re: Can the Bolt be left on when charging at a 3rd Party place?

Yes, and it's advantageous to do so in the winter. It activates the battery heater and allows your car to charge faster. I do it all the time.

Re: Keeping the 2020 Bolt plugged in

If you keep it plugged in it's best to limit charge level to 90% or less. Charge up to 100% if you're going to leave soon and you need the extra range. Once charged, the battery will pull little to no extra power (no effect on utility bill). If it's really cold in the winter, it might pull a few kW ...
