Temperature controlled heating elements. Cars such as the Chevy Bolt and Tesla heat the batteries when they drop below a certain temperature. When the car is plugged in, that energy comes from the grid, and when it isn't plugged in, comes from the battery itself.
In fact, one guy stranded himself in his Bolt when he ran the state of charge below the threshold that the car requires to heat the battery, and then attempted to DCFC. The car won't use DCFC power to run the heating element, and the battery was too cold to charge, so it was stuck until he could first plug into an AC outlet to warm the battery, and then into the DCFC to quickly charge.
