Analysis of a battery thermal management system based on KULI simulation
The simulation model of a battery thermal management system is established by using the simulation software KULI.The model includes compressor,Chil-ler,condenser,expansion valve,condensing fan,pipeline and other components of the air-conditioning refrigeration system.All component models are based on the existing technical parameters,mathematical model dimensions and measured test bench data of the components;After the model is established,the condenser and the Chiller need to calibrate the model to ensure that the simulation data and the bench data are within a cer-tain tolerance range,which proves the accuracy of the simulation model;Finally,the cou-pling simulation model of battery coolant cycle and air conditioning refrigerant cycle is built based on the real part data.After the model is established,different boundary condi-tions such as ambient temperature,fan gear,compressor speed,coolant temperature,etc.can be changed,and various performance parameters of the system can be obtained through simula-tion.Finally,the purpose of studying the influence of different boundary conditions on the per-formance and economy of battery thermal management system is realized.
