Systems and methods for driving a motor of an electric vehicle using a secondary battery are disclosed. A vehicle may include a first battery module having a first operating voltage configured to drive the motor, a second battery module having a second operating voltage lower than the first operating voltage, and a bidirectional converter. The controller may be configured to detect a thermal parameter exceeding a predetermined magnitude while the vehicle is in a parked position, and in response modify a supply voltage of the first battery module, and thereafter to drive the electric motor using electrical power supplied by the second battery module, thereby moving the vehicle from the parked position.
