Cooling Optimization of Hybrid Vehicle Thermal Management System
In order to make the energy control and utilization of the vehicle more reasonable and effective,so as to improve the performance of the vehicle,a hybrid vehicle was taken as the research object,and the air conditioning system model and the battery motor cooling system model were built based on a simulation software,and then a coordinated thermal management system model was synthesized.Through structural optimization of the thermal management system model,the battery pack could be cooled by both air cooling and liquid cooling.A control scheme for heat transfer and conversion between the air conditioning system and the battery pack cooling system was proposed,and the cooling scheme of the air conditioning cabin independent thermal management system and the cooling scheme of the air conditioning cabin and the battery pack collaborative thermal management system were compared under NEDC conditions.The results showed that under the premise of ensuring the comfort of the cabin,the cooling scheme using the air conditioning cabin and the battery pack collaborative thermal management system could be more energy saving,and conducive to the improvement of the remaining power and driving range of the vehicle.
