Description
Summary:This paper presents an improved method of modelling the hysteresis effect in batteries using the discrete preisach model. The hysteresis effect can be seen as a path-dependent effect or history-dependent effect on the lithium ion battery. This effect complicates the relationship between State of Charge (SOC) and Open Circuit Voltage (OCV) as it is no longer simply a one to one relationship, but rather it is depending on history of the battery. To solve the aforementioned effect, a discrete preisach model is implemented in an improved battery model to encapsulate the SOC-OCV relationship.
