The scope of this research work is the analysis and study of the rechargeable batteries. During this research, battery testbeds are developed for all under study battery technologies. A few hundreds of charging, discharging experimentation has been performed under a variety of charging profiles and discharging load patterns. These observations have been critically analyzed to capture the behavior of the batteries comprehensively. These behavioral profiles of these batteries have been utilized for developing an accurate battery model. The proposed model is a hybrid model composed of Diffusion model and combined electric circuit-based model, which accounts for nonlinearities of rate capacity effect, recovery effect, capacity fading, storage runtime and open circuit voltage, current-, temperature-, dependency to transient response. This proposed model would be a great help for energy aware circuit designing, because it’s an equivalent circuit model that could be co-simulated in circuit simulation environment, like Matlab Simulink. A quantitative figure of merit for the selection of battery system for a specific microgrid application has been devised on the bases of important battery parameters.
