The invention discloses a power assembly, a control device, a motor controller and an electric vehicle. The power assembly comprises a driving motor and a transmission device. The transmission device disconnects the transmission connection between the driving motor and the wheels according to the comparison result of the temperature or viscosity of the lubricating oil and a preset parameter value, and the rotating speed of the driving motor changes according to the comparison result of the temperature or viscosity of the lubricating oil and the preset parameter value. The driving motor stirs the lubricating oil through idling so that the temperature of the lubricating oil rises rapidly. The control device is used for controlling the motor controller, the transmission device and the lubricating oil pump motor. According to the power assembly, the control device, the motor controller and the electric automobile, the flowing property of the lubricating oil can be improved under the extremely low temperature condition, so that the lubricating oil pump can be smoothly started.
