The invention relates to an energy management method and device for an extended-range vehicle, a controller and a storage medium. The extended-range vehicle takes a range extender as a first power source. The method comprises the following steps: acquiring the current residual electric quantity of a power battery; according to the current residual electric quantity, the preset minimum residual electric quantity and the preset maximum residual electric quantity of the power battery, controlling the range extender to carry out conversion of the working modes so as to complete energy balance of the extended-range vehicle, wherein the number of the working modes of the range extender is three, the output power of the range extender in different working modes is different, and the output powerof the range extender in the same working mode is fixed. The method can reduce the adjustment frequency of the range extender, thereby reducing the noise of the energy system and prolonging the service life of the energy system.
