The invention provides a range extender power supply control method and device. The method comprises the following steps: determining a current driving mode and a current road mode of the vehicle; determining an energy consumption ratio corresponding to the current driving mode according to the default energy consumption corresponding to the current driving mode and the default energy consumption of the reference driving mode; determining a battery SOC coefficient corresponding to the current road mode according to a default battery SOC value corresponding to the reference road mode; according to the energy consumption ratio and the battery SOC coefficient, a basic battery SOC threshold interval used for controlling the range extender to start and a basic battery SOC recommendation threshold are adjusted; and determining the current power guarantee mode of the vehicle, and controlling the range extender to start power supply or stop power supply based on the range extender power supply control mode corresponding to the power guarantee mode, the adjusted basic battery SOC threshold interval and the basic battery SOC recommended threshold. According to the method, the starting SOC threshold value of the range extender and the starting and stopping control modes can be flexibly set, and the use flexibility and the driving performance of the vehicle are improved.
