There is disclosed a controller for an electric vehicle that allows for securing a sufficient battery capacity and is able to substantially avoid giving an uncomfortable feeling to the crew even if an engine for power generation is started. The controller comprises a power generation control unit which makes a generator of the electric vehicle generate electric power by starting a generator-driving engine of the electric vehicle in the case that an SOC (state of charge) of a battery of the electric vehicle is equal to or less than a first value, and further makes the generator generate the electric power by starting the generator-driving engine in the case that the SOC of the battery is equal to or less than a second value larger than the first value and a predetermined condition is satisfied. Further, an electric vehicle provided with such a controller is also disclosed.

[ What is claimed is:] [1.] An electric vehicle, comprising:an electric motor driving said electric vehicle;a battery storing electric power to be supplied to said electric motor;a generator to generate electric power so as to supply said electric power generated by said generator to said electric motor and/or said battery;an engine making said generator generate said electric power;a first sensor detecting a state of charge (SOC) of said battery;a second sensor detecting an operative condition of said electric vehicle; anda controller enabling said generator to generate said electric power by starting said engine when said SOC detected by said first sensor is equal to or less than a first value, and enabling said generator to generate said electric power by starting said engine when said SOC detected by said first sensor is equal to or less than a second value larger than said first value and said operative condition of said electric vehicle is detected by said second sensor, while not starting said engine to enable said generator to generate said electric power when said SOC detected by said first sensor is equal to or less than said second value but said operative condition of said electric vehicle is not detected by said second sensor,wherein there is a region in which said controller does not start said engine to enable said generator to generate said electric power when said SOC detected by said first sensor is more than said first value and equal to or less than said second value after said controller does not start said engine to enable said generator to generate said electric power when said SOC detected by said first sensor is equal to or more than said second value but said operative condition of said electric vehicle is not detected by said second sensor.
