Research on Optimization Technology of Aviation Lithium-ion Battery Pack Based on SP+Model
With the development of more electric aircraft and lithium-ion battery technology,lithium-ion battery has been extensive used in the aviation field.In addition to emergency battery,it is more and more used in aircraft as power battery.Due to the aircraft has high requirements for the weight,volume and other characteristics of lithium battery pack,it is necessary to optimize the design.The optimization design based on model can effectively reduce the cost and shorten the cycle time.Be-cause the SP+electrochemical model can accurately reflect the working mechanism of lithium-ion battery,and has the characteristics of high accuracy and simple calculation,this paper uses the SP+model to build and verify the lithium-ion battery model.At the same time,taking typical power con-sumption conditions as an example,the simulation analysis and optimization design of aviation lithi-um-ion battery pack are carried out,and the weight and volume of lithium-ion battery pack are opti-mized.
