Abstract
The present disclosure provides a heating control method and a heating control device. The heating control method includes: acquiring an average current value in a heating circuit of a power battery pack; calculating a current output value required for ncycle according to an average current value of the ncycle, an average current value of (n−1)cycle, an average current value of (n−2)cycle, a preset current value, n is equal to or greater than 3; outputting a PWM signal to a switch device of the heating circuit according to a pre-calibrated PWM control parameter corresponding to the current output value so that a difference between an actual current value in the heating circuit and the preset current value is less than a preset threshold.
