A variable control device of an electric drive energy storage type workover rig is applied to an oil field workover rig. A foot treadle is arranged in an operator cabin of the electric drive energy storage type workover rig and connected with a variable controller through a shaft sleeve; the variable controller is connected with a main control box through a signal wire; a storage battery charging/discharging device is connected with an inverter through a cable; a charging/discharging manager is connected with a storage battery through the cable; the inverter is connected with a main motor through the cable; the main motor is connected with the main control box through the signal wire; the inverter is connected with the main control box through the signal wire; and the storage battery charging/discharging device is connected with the main control box through the signal wire. The variable control device of the electric drive energy storage type workover rig has the benefits that the driving speed per hour of the energy storage type workover rig can be controlled, so as to ensure the normal and safe driving of the energy storage type workover rig.
