The invention discloses a power assembly, a motor controller, a motor controller control device and an electric vehicle. The power assembly is used for heating a power battery of the electric vehicle. The working modes of the power assembly comprise a battery internal resistance heating mode and a driving motor heating mode, the power assembly can selectively operate in different working modes according to different conditions, and the heating power in each working mode can be adjusted. The motor controller can output high-frequency pulse current or motor exciting current to heat the power battery, and the motor controller can selectively output the high-frequency pulse current or the motor exciting current according to different conditions. The motor controller control device controls the motor controller to output pulse current or motor excitation current by controlling the on-off of each switch tube of three bridge arms of the motor controller. According to the power assembly, the motor controller, the motor controller control device and the electric automobile, the heating efficiency of the power battery and the energy utilization efficiency of the electric automobile can be improved.
