Disclosed is a driving circuit for an electric vehicle having a battery pack and an inverter, and a control method thereof. The driving circuit includes a first contactor connected between a first terminal of the battery pack and a first terminal of a capacitor included in the inverter, a second contactor and a current limiting circuit connected to the first contactor in parallel, and a control unit configured to control operations of the first contactor and the second contactor. The second contactor and the current limiting circuit are connected to each other in series. The current limiting circuit includes at least one resistor, wherein the control unit outputs a first control signal when the first contactor is normally operating and outputs a second control signal when the first contactor is abnormally operating. The first control signal induces the first contactor to turn on, and the second control signal induces the second contactor to turn on.
