Do you guys typically keep your Bolt on when plugging it in or do you turn it off, plug in then turn it back on?

I usually just get out plug in to The DCFC and get back in, without turning the car off. I’m not sure if I should be doing that or not.

If the charger starts, you are just fine. I think some DC fast chargers will only start if the car is turned off.

I've done it both ways on several occasions and never had an issue either way.

The only issue I've had is with some of the newer high-capacity chargers that have thick, stiff cables - they can apply a sideways pull on the charging plug that prevents it from engaging the safety latch, and when that happens the charger won't be able to start the charging session. The solution to that is to hold onto the plug so that it's perpendicular charging port as you start charging - that relieves the pressure so that the latch can engage and the session can start. Once charging has started, you can let go of the plug.

It doesn’t matter how you do it. I often, (when using a public charger), leave the car on so I can see when it estimates it will be full.
i often use DCF, & in the winter leave everything run so it’s warm inside while charging. The car figures it out & begins. You will get the triple horn chirp if leave it running, get out & close the door to hook up the charger.
i use ChargePoint, FLO, & the Petrocan DCFC here in Canada, & it didn’t matter if I left it running.
ome thing with DCFC, you have to connect, then press the START button on the DCFC cabinet. I’ve been in a hurry on a cold day, jumped back in the car, wondered why it wasn’t charging...whats that flashing light on the cabinet, the one that says START...DUH!
with DCFC you can also crank the heater, & the electric supply system will put out as much as the Bolt battery will accept.

The only issue with leaving the car run, if on a commercial Level II, (which are usually at 6.6 Kw), is the car uses 1Kw at idle, & quite a bit more with the heater running. This might drop your charge rate down to 3Kw.
DCFC, no issue, the system ramps up to what the battery will accept.

The display always show 1kw on idle. It is actually less than that most of the time. Whatever it is just gets rounded up to 1kw. Torque pro will show the actual power consumption at idle.

I never keep the on during charging, as there has been no need to, yet.

It WILL slow the charging down but not by much.
