Catchy title! But it's mostly true! There's a pinned comment you might want to read, as well. But there's some links down here, too.

A quick correction for you, the battery heater does function when CCS charging in cold conditions. The complaint is that charge rate is reduced when the battery pack is cold, and the heater is only 2 KW. The problem is that the battery heater shuts off around 64F pack temperature, and at that point maximum charge amps is still limited to less than 110 amps. This may seem like a lot, but the Bolt max charging amps with a warm battery is 150 amps. I think the logic was that when they set up the programming for the system, most publicly available CCS chargers maxed out at 100 amps, with a few 125 amp stations. Now with lots of 125 amp stations and 150+ amp stations becoming available they need to reprogram the battery heater to vary it's shut off point based on power available, so it stays on to a much higher pack temperature when connected to a higher power CCS station to maximize charging rate.

Firstly and of supreme importance, the video on the Bolt's Bits from Weber Auto - Prof. John Kelly is amazing and you really ought to give that channel a look if you're interested at all in hybrid and ⚡ EV tech;
