电池荷电状态校正算法

Study on battery SOC correct algorithm

荷电状态校正算法主要用于电动汽车仿真程序中,调整蓄电池荷电状态的初值,使仿真结果更接近于汽车的真实性能。在分析荷电状态校正算法的基础上,应用电动汽车仿真软件ADVISOR对一混合动力轿车的实例分别进行了无荷电状态校正算法、线性荷电状态校正算法和零差值荷电状态校正算法的仿真,并且进行了比较和分析,最后对荷电状态校正算法的效果作了综合评价。

SOC is used to adjust the initialization SOC value so as to make electric vehicle simulation result to be close to real vehicle performance. This paper firstly analyzes the battery SOC correct algorithm,then uses ADVISOR which is an electric vehicle simulation software to simulate a hybrid electric car with three different cases of no SOC correct,linear SOC correct and zero delta SOC correct,as well as makes the compare and analysis for those simulation results.In the end,an overall conclusion to SOC correct algorithm is given.
