The invention relates to the field of new energy automobiles, and provides a range extender multi-working-point real-time switching control method and device. The method comprises the following steps: constructing a first multi-objective optimization function; based on the expected rotating speed, the expected torque and the first multi-objective optimization function, the optimal working interval of the range extender is determined when the comprehensive performance of the whole vehicle is optimal; based on the real-time whole vehicle demand power value and the real-time battery SOC value of the vehicle, the range extender is controlled to be switched among the low-load working point, the medium-load working point and the high-load working point, and the range extender is controlled to be in the working point switching period, the continuous working time of the low-load working point does not exceed the first minimum working keeping time, and the second minimum working keeping time does not exceed the second minimum working keeping time. The continuous working time of the medium-load working point does not exceed the second minimum holding working time, and the continuous working time of the high-load working point does not exceed the third minimum holding working time. According to the invention, the energy distribution management mode of the extended-range automobile is optimized, and the comprehensive performance of the whole automobile can be improved.
