Design of the Control System of the Electric Vehicle with Range-extender

In order to improve the controllability of electric vehicle,the flexibility of the motor control system and to extend the driving range,a kind of control system of electric vehicle with range-extender that used microcontroller with special integrated circuits was proposed.The peper introduced the control scheme of the system,designed and evaluated the control strategy of the vehicle by mathematical calculation and analog simulation.The system adopted the modular design.Special integrated circuits was mainly to control the motor,so as to reduce the work burden of the microcontroller.The microcontroller was mainly used to control special integrated circuits,and realize the control strategy of the vehicle system by controlling the opening of the extender on the basis of battery SOC values.The effective combination of the control of vehicle,extender and motor was realized.Test of the response performance of motor and debugging of the vehicle.
