Improved lithium-ion battery model with hysteresis effect

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.
