When the battery's temperature is at 10C (50F) or below, the maximum DCFC charging speed of a Bolt gets limited to about 21kW and then slowly climbs up as the battery heats up. What you've reported is perfectly in line with what you should experience in winter and there's nothing wrong with your car.

I've actually touched on this on one of my videos... It's in Korean, but turn the translation on for the subtitles and take a look at the graphs. Here's the link that goes to the relevant part at 06:07.

Thank You Wesley.. Really want to see Charging rates by Tempature right on the Window Sticker. We went over this a year ago. Some Countries do require seasonal ranges listed... that would really help new EV buyers
