摘要: 在频繁启停的道路工况下,针对纯电动车复合电源出现超级电容组电量消耗过快的问题,提出一种基于逻辑门限的功率控制策略,通过PID闭环控制方法,控制蓄电池组的输出功率,减小超级电容组电量的消耗,并在MATLAB/Simulink软件上搭建了带有功率控制策略的复合电源模型,仿真结果表明:功率控制策略有效降低了超级电容组荷电状态下降速度,系统工作稳定,响应速度快,控制精度高。

Abstract: Under the road condition of frequent start and stop, the electricity of super capacitor bank consumed too much in pure electric vehicle compound power supply. A Logic threshold power control strategy was put forward; PID closed-loop control method was used to control the output power of the battery and reduce the power consumption of the super capacitor bank. A compound power supply model with power control strategy was built on Matlab/Simulink software. The simulation results show that the power control strategy effectively reduces the SOC descent speed of the super capacitor bank. The proposed system works stably, the response speed is fast, and the control accuracy is high.
