The invention discloses an extended-range electric vehicle, a range extender control method and device thereof and a storage medium, and relates to the technical field of hybrid vehicle power supply, and the method comprises the following steps: obtaining the road driving condition of the extended-range electric vehicle and the residual electric quantity of a power battery of the extended-range electric vehicle; if it is monitored that the residual electric quantity of the power battery is lower than a first electric quantity threshold value, and it is determined that the maintaining duration when the driving gradient of the range-extended electric vehicle is not smaller than a first gradient threshold value reaches a first duration threshold value according to the road driving working condition, a range extender of the range-extended electric vehicle is started; the first electric quantity threshold value is greater than a standard electric quantity threshold value for defining the feed state of the extended-range electric vehicle; and the generated power of the range extender is adjusted according to the whole-vehicle required power of the range-extended electric vehicle, so that the generated power of the range extender follows the whole-vehicle required power of the range-extended electric vehicle. The technical problem that the range extender cannot meet the power supply requirement of a user in a high-power driving scene is solved.
