摘要
为了降低实验成本,该文采用MATLAB/Simulink软件设计了电池组充放电及均衡的虚拟实验系统。该系统由GUI界面、Simulink/Simscape元件组成的仿真模型组成,具有充电、放电、均衡等多种仿真模式,可通过弹出式菜单选择指定模式进行仿真分析,并以曲线的形式显示仿真结果。系统GUI界面操作简单,便于学生熟悉电池的充放电特性;Simulink仿真模型为学生进行均衡设计及算法学习提供实例,有助于提高学生的电池管理系统综合设计能力。基于该系统,可设计电池充放电虚拟仿真实验、电池均衡虚拟仿真实验两个实验项目,帮助其了解电池特性,熟悉电池均衡方法。
To reduce the experiment cost,a virtual experiment system for battery charging,discharging and equalization is designed using the MATLAB/Simulink software.Consisting of simulation models that are comprised of the GUI(Graphical User Interface)and Simulink/Simscape components,the system has numerous simulation modes,such as charging,discharging and equalization.Simulation analysis can be conducted by choosing designated model through the pop-up menu,and the simulation results are displayed in the form of curves.The GUI is easy to operate,so that students may be familiar with the charging and discharging characteristics of batteries.The Simulink simulation model provides students with examples of balanced design and algorithm learning,which is conducive to improving their integrated design ability of the battery management system.Two experimental projects of battery charging and discharging virtual simulation experiment and battery equalization virtual simulation experiment designed based on this system can improve students'understanding of the characteristics and equalization methods of the battery.
