Abstract
A control device for an electric vehicle where a threshold storing unit is provided which stores two large and small thresholds and (first threshold>second threshold), and a drive state switching unit is provided which reduces torque output of a drive motor, while allowing accessories to operate, when a remaining energy capacity SOC from a remaining energy capacity detecting unit fails below the first threshold, and stops power supply to the drive motor, while allowing the accessories to operate, when the remaining energy capacity SOC from a remaining energy capacity detecting unit falls below the second threshold.
