Analysis of the memory effect of lithium iron phosphate batteries charged with stage constant current

Abstract

Abstract Lithium iron phosphate batteries are widely used in various fields and have long been considered to have no memory effect. It is not until recent years that the memory effect of lithium iron phosphate batteries has been discovered and studied. In engineering applications, electric vehicles are usually charged with stage constant current. Here, we first briefly explain the process of memory effect generation. Make the battery have a memory effect under different charging methods. Compare and analyze the characteristics of memory effect under each charging method for optimization ideas of development ChaoJi and other high-power and high-current charging technologies.
