摘要
为提高纯电动商用车驾驶室热舒适性和整车能量利用效率,对某纯电动商用车集成热管理系统控制策略进行优化.利用AMESim建立纯电动商用车集成热管理系统模型,采用MATLAB/Simulink建立系统控制模型,将两种模型耦合并进行联合仿真.结果表明,优化后的能量平衡式控制策略能够满足驾驶室和电池制冷需求,相较于传统通断式控制策略,驾驶室温度更稳定,在单驾驶室制冷模式、单电池包制冷模式和同时制冷模式下分别节省压缩机能耗 0.48、1.62、2.37 kW·h.能量平衡式控制策略在驾驶室热舒适性和能效比方面均优于通断式控制策略.
Abstract
To improve the thermal comfort of the cabin and the overall energy utilization efficiency of a pure electric commercial vehicle,the control strategy of the integrated thermal management system for a specific pure electric commercial vehicle was optimized.AMESim was used to establish a model of the integrated thermal management system,and MATLAB/Simulink was used to build the system control model.The two models were coupled for co-simulation.The results showed that the optimized energy balance control strategy can meet the cooling demands of both the cabin and the battery.Compared to the traditional on-off control strategy,the cabin temperature was more stable,and compressor energy consumption was reduced by 0.48、1.62、2.37 kW·h under the cabin-only cooling mode,battery pack-only cooling mode,and simultaneous cooling mode,respectively.The energy balance control strategy outperforms the on-off control strategy in both cabin thermal comfort and energy efficiency.
