An electric vehicle having a generator includes a body, an electric machinery, an electric machinery controller, a battery and a generator. The generator generates electricity to the battery and provides power supply to the electric machinery through the electric machinery controller for driving wheels of the body to advance. The electric vehicle further includes a control system. The control system includes a central processing unit (CPU), a battery voltage detection module to detect a voltage value of the battery and send the voltage value of the battery to the CPU, a comparison module to compare the voltage value of the battery with a preset maximum voltage value and a preset minimum voltage value and send a comparison result to the CPU, a battery output current detection module to detect an output current value of the battery and send the output current value of the battery to the CPU, a generator output voltage detection module to detect an output voltage value of the generator and send the output voltage valve of the generator to the CPU, the CPU being adapted to receive the aforesaid data and analyze for controlling the generator to work and its output status. The present invention ensures that the electric vehicle is able to drive outdoors continually without causing any harmful effect to an electric machinery controller and a battery so as to provide a certain protection to the battery.
