Abstract

Abstract: Cycle life of power batteries greatly affects the service life of electric vehicles, which is an important factor of economic benefits. In addition to the cycle life studies of lithium-ion battery cells, the cycle life of module and battery system is more significative due to they are close to practical application. In this paper, using lithium manganate pouch cells as smallest testing unit, the electrochemical characteristics, capacity attenuation and temperature variation of monomer-modulebattery system are systematic analyzed. Results show that in the cooling condition, the relationship among the attenuation of three levels is battery system > module > cell; in terms of cycle temperature, module > cell > system. The results of three-dimensional hierarchical relationship illustrate the interfacial structure-activity relationship in capacity attenuation and temperature variation, which provides a reference for the study of cycle aging process of lithium traction battery system.
