摘要:
为了探讨能量管理策略对增程式电动汽车燃油经济性提升的潜力,以某增程式电动客车动力系统作为研究对象,在电量消耗- 电量保持模式( CD-CS) 和混合模式( Blended) 两种不同的增程式电动客车单日运行方式下,提出一种基于凸优化的能量管理策略。考虑增程器在不同输出功率下燃油经济性最优工作状态,以最小燃油消耗和电能消耗作为目标函数,对增程式电动客车能量管理策略进行优化,并对两种不同运行方式下的优化结果进行了对比。仿真结果表明,在中国哈尔滨城区道路工况条件下,单日出行里程为218. 27 km 时,利用凸优化的能量管理策略,相较于CD-CS 运行方式,Blended 运行方式的增程式电动客车系统能耗下降3. 56%,电池平均电流减小了2. 05%,最大充电电流减小了45. 8%,最大放电电流减小了23. 9%,增程器平均效率提高了0. 98%,系统驱动能效提高了3. 66%。
Abstract:
In order to explore the potential of energy management strategy in enhancing the fuel efficiency of extended range electric vehicles,a power management strategy based on convex optimization is proposed under two different operation modes,CD-CS and Blended,of extended-range electric buses in single day with the power system of an extended-range electric bus being as the research object. Taking the minimum fuel consumption and electric energy consumption as the objective function, the energy management
strategy of the extended-range electric bus was optimized,and the optimization results in the two different operation modes were compared,and the optimal operation state of the fuel-economy of the extended-range engine under different output power was considered. The simulation results show that under the road condition of Harbin urban area of which the mileage of single-day trip is 218. 27km and using the convex optimization of energy management strategy,compared with CD-CS operation mode, the energy consumption of electric bus system based on blended operation mode is reduced by 3. 56%; the mean current of the battery is reduced by 2. 05%; the maximum charging current is reduced by 45. 8%; the maximum discharge current is decreased by 23. 9%; the average efficiency of the booster is improved by 0. 98% and the system-driven energy efficiency is improved by 3. 66%.
