摘要
基于Matlab/Simulink搭建了增程式电动环卫车正向仿真模型,在我国典型城市公交工况下,对增程器的开关模式、持续运行模式、恒定功率输出模式和功率随动输出模式等4种能量管理策略进行100 km的连续仿真,结果表明,增程器开关模式和持续运行模式均可使电池组SOC维持在合理的区间,但恒定功率输出模式比功率随动输出模式的等效百公里油耗小,最小为29.13 L;设置较小的增程器输出功率能够使电池SOC变化平稳,避免电池组的频繁充、放电现象。
Based on Matlab/Simulink, the forward simulation model is conducted for a range-extended electric sanitation truck. Four energy management strategies of range-extender, including switching mode, continuous operating mode, constant power output mode and power servo output mode are simulated continuously for 100 km in typical urban public transport conditions. The results show that both the switching mode and the continuous operating mode can make the battery SOC work on a reasonable interval; but the constant power output mode has less fuel consumption than the power servo output mode with the minimum of 29.13 L. In addition, setting low output power of the range-extender can keep the state-of-charge of battery pack vary stably and avoid the frequent switch between the charge and discharge.
