The embodiment of the invention relates to a range extender power switching method and device, electronic equipment and a storage medium. The method comprises the steps that the current power and the target power of a range extender are determined; determining a first parameter variable quantity and a second parameter variable quantity from the current power point to a target power point in an expected power curve contained in the parameter relation graph; determining a slope corresponding to the current power point on the expected power curve; based on the first parameter variable quantity and the second parameter variable quantity, determining a first step length and a second step length by utilizing a parameter change step length table; comparing the slope with the ratio of the first step length to the second step length to obtain a comparison result; and respectively adjusting the first parameter and the second parameter to a first target value and a second target value according to an adjustment mode corresponding to the comparison result. According to the embodiment of the invention, when the power of the range extender is switched, the response speed and the control accuracy of the range extender are taken into consideration, meanwhile, the parameter working area of the range extender is located in a low-oil-consumption area as much as possible, and the economical efficiency is improved.
