The invention provides a micro gas turbine range extender control device for an electric automobile. The micro gas turbine range extender control device comprises a micro gas turbine, a fuel tank, a fuel pump, a flow control device, a high-speed motor, a coaxial part, an exhaust temperature sensor, a rotating speed sensor, a power conversion unit PCU, a power battery, a battery charging and discharging device and an electronic control unit ECU. The technical problem to be solved is to control a high-speed motor to start the micro gas turbine in an electric mode by using the control device. When the micro gas turbine operates under a rated working condition, the control device controls the high-speed motor to operate in a power generation mode and charges the power battery, and when the power battery is fully charged (the voltage of the battery end is higher than a set charging termination voltage), the control device controls the micro gas turbine to stop working. The significance of the invention lies in that the starting/power generation integrated high-speed motor is used for controlling starting and stopping of the micro gas turbine, non-stop charging is achieved, and the purpose of prolonging the driving range of the electric automobile is achieved.
