An equivalent circuit battery model in [2] [3] is used to represent battery terminal voltage dynamics as a function of battery current. The model is based on Thevenin''s theorem to model the current and voltage profile of the battery as a black box input-output device. A first-approximation assumption is made such that the battery state
