Equivalent Circuit Model for a NiMH Battery

Application ID: 68301


A simple equivalent circuit model approach is presented for Nickel metal hydride batteries. The 0D model consists of resistor, capacitor, current source and state-of-charge based voltage source (SOC). An Arrhenius type dependence is used to account for self-discharge. All model parameters are either constants or function of SOC. A time dependent study for a charge discharge cycle for various C-rates is presented.

This model example illustrates applications of this type that would nominally be built using the following products:
