The System Of Intelligent Control Charging For Wind/photovoltaic Hybrid Electric Vehicle

Currently, the technology of wind and solar power generation is quite mature, theelectric car is also gradually growing and developing. It is topic innovative ideas thatusing wind and solar power generation to electric vehicle charging which provides a newconcept for the reuse of new energy sources. The technology is not only environmentallyfriendly, clean, but also reduce the pressure of the mains supply. So the wind andphotovoltaic hybrid electric vehicles will dominate in the automotive industry in thefuture.The core of wind and solar power is system control and monitoring, includingmaximum power tracking, battery charge, discharge management, monitoring of thecharging stations technology and so on. On the basis of the original design of a wind andsolar, a intelligent control system of wind and solar power generation to electric vehiclecharging is designed, and make use of the renewable energy to generate to provideenergy to the electric vehicle, and monitor the real-time data of system.The three-stage charging method is used in battery charging, and in order to preventbattery charging less and overcharging, the limited value of voltage and current are set tocontrol the battery charging in each stage. According to the size of voltage on the DC bus,it is determined whether the system is to achieve the balance of energy, and the size ofthe output energy of various parts (solar energy, wind turbine, battery and electric vehicle)is reasonable controlled, and a control strategy is proposed. Making use of the CAN bustechnology, the CAN bus communication between the charger and electric vehicles isachieved, and the application layer is defined in the subject. MCGS configurationsoftware is used to design interface on the terminal monitoring. Accordingly, it achievesreal-time monitoring of system’s health, while establishes a database for the managementcontrol. The process of wind and solar power generation controlling is simulated by usingMatlab, achieving the maximum power point tracking controlling of the wind power andphotovoltaic power generation and electric load tracking controlling.It is feasible for charging to the electric vehicle by using of wind and solar powergeneration through simulating the experiment, and it achieves the monitoring andcontrolling effect by controlling strategy which is proposed by subject.The above research results achieve the effect that using wind and solar power cangenerate to the electric vehicle charging, and bring about the function that using newenergy to electric vehicle charging, which finds a breakthrough in the development ofelectric vehicles.
