The Design Of 4KW Solar Weliding Engineering Vehicle Control System

In today’s world, sustainable development has gradually risen to the mainstream trend of development, traditional automobiles as important sources of high energy consumption and emission pollution, are facing serious challenges of development. Energy conservation and environmental protection are becoming the new goals of automobile manufacturing industry. The development of electric vehicles is solving the problem of emissions, but most of the power comes from fossil energy and vehicles have short mileage-range. Solar energy is a huge reserves, safe and clean energy, the solar panels can convert solar energy into electrical energy to solve the existing problems of energy. This paper designs a new energy vehicle combining electric vehicle technology with solar power technology which is used to drive the vehicle and welding in different time, this vehicle can be used in remote area without electricity networks covering.Through the comparison of system structures between electric and hybrid cars, this paper completes the system structure design and parameters of solar engineering vehicle, according to the design requirements, and completes the selection and calculation of key parts of the vehicle through analysis and comparison. On this basis, the paper redesigns the control system of engineering vehicle and formulates the corresponding energy control strategy under different conditions, at the same time, the peripheral circuit of control system is analyzed and designed in detail. This paper also focuses on the analysis of the characteristics of the solar battery and the factors affecting the output of solar battery, using the model established by Simulink. At the same time, the paper completes the data monitoring of photovoltaic power generation system of solar engineering vehicle, compares results with the theoretical calculation, and completes the test of welding equipment. Finally the system of engineering vehicle is simulated in the ADVISOR software. The simulation includes the SOC changes of battery, mileage, acceleration time and other aspects of the vehicle under different driving conditions. This paper evaluates vehicle performance and verifies the rationality of the design by the simulation results, on the basis of the results, the vehicle design parameters are optimized and improved.
