Simulation Analysis of the Power System of Solar Electric Vehicle based on Matlab/Simulink

太阳能电动汽车由于具有节能环保、资源丰富的优点,已经受到各国的普遍关注。本文对太阳能电池板进行了分析选取、安装设计和参数匹配。基于建立的太阳能电池仿真子模型,设计整车参数,对动力系统关键零部件电机、动力电池进行选型和匹配,对整车进行性能仿真,并与原车仿真结果进行对比分析。结果表明:该车的最高车速、加速性能和最大爬坡度等动力性能指标均满足设计要求,经过匹配的太阳能电动汽车动力系统可以很好的满足车辆性能要求,也证明了加载的太阳能系统能够分担汽车的部分功率,在一定程度上能提升整车的续驶里程。

Solar electric vehicles have been widely concerned by all countries because of their advantages of energy saving,environmental protection and abundant resources.In this paper,solar panels are selected,installed and matched with parameters.Based on the established solar cell simulation sub-model,vehicle parameters are designed,the key components of the power system such as motor and power battery are selected and matched,the performances of the vehicle are simulated,and the differences in the simulation results from original vehicles are compared and analyzed.The results show that the vehicle’s maximum speed,acceleration performance and maximum grade ability and other power performance indexes meet the requirements of design,and the matched solar electric vehicle power system can greatly meet the vehicle’s requirements of performance.And it has been proved that the loaded solar energy system can share partial power of the vehicle,to a certain extent,thus improving the entire vehicle’s driving range.
