Modelling and Simulation of Storage Battery on Electric Vehicles

对蓄电池建模方式进行了探讨,采用等效电路模拟并建立键合图模型,对SOC的计算进行了讨论,并采用更加合理的算法,讨论了蓄电池散热系统的键合图建模方法并建立了散热系统的键合图模型。将蓄电池等效电路的键合图模型和散热系统的键合图模型耦合在一起,建立了蓄电池系统的键合图模型,并由此导出数学模型,基于MATLAB/SIMULINK平台建立仿真模型,实现了蓄电池的动态仿真,并与ADVISOR软件的仿真结果进行了比较分析。

Based on the theory of bond graph introduced, this article portraits the bond graph model of storage battery and its cooling system on electric vehicles, with research on SOC calculation via a better algorithm. A coupling of bond graph models of equivalent circuit and cooling system is presented to set up a dynamic simulated model based on MATLAB/SIMULINK and the results are compared with those of ADVISOR.
