The invention relates to the field of new energy automobiles, and provides a range extender working point dynamic transfer method and device, a vehicle and a readable storage medium. The method comprises the steps that the current expected power generation rotating speed and the current expected power generation torque are determined; determining a current control power generation rotating speed based on the current actual power generation rotating speed, the current expected power generation rotating speed and the current expected power generation rotating speed; determining a target adjustment coefficient; determining an adjustment power generation torque according to the current control power generation rotating speed, the current expected power generation torque and the target adjustment coefficient; determining a first filter coefficient; obtaining a current control power generation torque based on the first filter coefficient and the adjustment power generation torque; and controlling the range extender to dynamically transfer from the current actual power generation rotating speed to the current control power generation rotating speed and to dynamically transfer from the current actual power generation torque to the current control power generation torque. The power generation efficiency, the power generation power stability and the power output response rate of the range extender can be considered in a complex scene, and the optimization of the comprehensive performance is achieved.
