The invention discloses an extended-range hybrid power system, a control method and a crane, and belongs to the technical field of engineering machinery. The extended-range hybrid power system comprises a power battery, an all-in-one controller, a first motor, a second motor and an engine. The first motor is connected with a getting-off traveling mechanism; the engine is connected with a second motor, and the second motor is connected with a loading operation mechanism; the power battery, the first motor and the second motor are connected with an all-in-one controller, and the all-in-one controller is connected with an external power source. One of a plug-in working mode, a pure electric working mode, a pure oil working mode and a hybrid working mode can be selected for getting-on operation, a pure electric driving mode or a range extending driving mode can be selected for getting-off driving, the working efficiency of an engine can be improved, fuel consumption and tail gas emission are reduced, and the environmental protection performance is high.
