Energy control method and device of range extender, electronic equipment and storage medium

The invention discloses an energy control method and device of a range extender, electronic equipment and a storage medium, the method and device are applied to the electronic equipment of the range extender, and specifically, the method comprises the steps that the whole vehicle demand power of a vehicle provided with the range extender is judged so as to determine whether the whole vehicle demand power exceeds a preset power threshold value or not; when it is judged that the required power of the whole vehicle does not exceed the power threshold value, an engine of a range extender is controlled to operate based on a constant power mode; and when it is judged that the required power of the whole vehicle exceeds the power threshold value, the engine is controlled to operate based on a multi-point power following mode. By means of the scheme, on the basis that the whole vehicle power requirement is met, the working point of the engine always operates in the optimal economic zone, and therefore the fuel consum
