Research On Modular Design And Evaluation Method Of A Company’s Electric Vehicle Battery Thermal Management Integrated Product

The electric vehicle industry has developed rapidly in recent years,with new forces emerging at home and abroad and established automakers accelerating the development of electric vehicles.For the electric vehicle,the battery thermal management system is very important,which is related to the vehicle’s endurance,safety and life.For the battery thermal management system and products of A Company,each OEMs put forward the requirements of optimizing the volume and installation mode,and shortening the research and development cycle;At the same time,each OEMs also have different personalized needs.Therefore,in order to meet the requirements of OEMs,modular design is applied to the integrated productsofelectric vehiclesand modularworkevaluation iscarried out.(1)Firstly,the function and importance of electric vehicle battery thermal management system and its components are described in this paper,and the existing problems are found;And then analyzes the theory and method of the modular design method research situation and application in various industrial fields,think that modular design can help quickly developed to meet different customer requirements of the electric car battery thermal management integration products,in improving the quality of the products at the same timereduce thecost,solvethe problemsexisting inthe electricvehiclebattery thermal management system.(2)The modular design method of integrated product for electric vehicle battery thermal management was proposed,including modular analysis of integrated product for electric vehicle battery thermal management,modularplatform establishment,modulardesign and application,etc.(3)The evaluation method of modular work of integrated products for electric vehicle battery thermal management was proposed,including:(a)modular work benefit evaluation,including: R & D efficiency improvement rate,quality benefit improvement rate,product reliability improvement rate,total cost reduction rate,customer benefit improvement rate,green benefit improvement rate;(b)Modularization level evaluation,including: module reuse rate,standard parts proportion,common parts proportion,product standardization rate.(4)Taking an electric vehicle battery thermal management integrated product of Company A as an example,the modular design and evaluation method are practiced.According to the technical requirements of the customers,the refrigerant flow regulation module,heat exchange module and coolant loop flow regulation modulewere developedrapidly by using product configurationdesign.Theassembly of mounting bracket and the sub-parts and sub-parts of the above three modules are rapidly developed through variant design.Finally,the design of the product was completed quickly on the premise of satisfying thecustomer’s personalized needs.
