Modeling and performance optimization of integrated thermal management systems for pure electric commercial vehicles
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.
