A control system for an electric vehicle equipped with a driving electric motor which is actuated by electric power, as supplied from a vehicle-driving battery, to drive a wheel of an electric vehicle, a power generating motor which is actuated by an engine to provide electric power to the vehicle-driving battery, and an air conditioner which works to regulate temperature in a cabin of the electric vehicle. The control system controls the engine so as to keep an output therefrom constant in response to an air condition request. The control system also keeps the output from the engine constant to actuate the power generating motor for charging the vehicle-driving battery when an amount of charge in the vehicle-driving battery is determined to be lower than or equal to a given threshold value, and the electric vehicle is determined to be at a stop.
