Modeling and Simulation of the Ni-Mh Battery

Abstract

This paper presents an improved and easy-to-use battery dynamic model. The charge and the discharge dynamics of the battery model are validated experimentally with Ni-Mh batteries types. An interesting feature of this model is the simplicity to extract the dynamic model parameters from batteries datasheets. Finally, the battery model is simulated in the matlab simulation software .The results show that the model can accurately re-present the dynamic behavior of the battery.

A New Method of Reference Signal Generation Applied To UPQC-PHEV For Grid Integration of WECS-SCIG

“…PHEV's give a way to design its bi-drectional charger as UPQC converters.PHEV's provide a way for storing of electric wind energy and solar photovoltaic energy at times of excess generation and use it as an ubiquitious power grid whenever needs for improvement of power stability and quality of those resoucres [10] To develop an appropriate model for PHEV, a dynamic and versatile model of rechargeable battery has chosen where the elements of battery are variable, as they depend on electrolyte temperature as well as State Of Charge (SOC) [15]. The Exp(s) transfer function represents the hysteresis phenomenon for the Lead-Acid, Ni-CD and Ni-MH batteries during charge and discharge cycles [16]. The exponential voltage increases when battery is charging, no matter the SOC of the battery.…”
