Low-complexity SPICE analog behavioral modeling of the ideal battery for system level design

This paper presents the implementation of an ideal battery model using Pspice behavioral-dependent sources, which considering cycle life and rate of discharge effects. The proposed circuit topology models the battery behaviors (e.g., runtime) with low complexity to design portable electronic devices at a system level. The proposed model was simulated in OrCAD PSpice Designer® software using three study cases assuming three battery technologies (i.e., ideal Battery, Li-Ion, Lead-Acid) with constant and pulse (with duty cycle 50%) discharge current under five different discharge average values (i.e., 1C, 2C, 3C, 4C, and 5C). The runtime results present a good agreement between the simulated and theoretical values, with a mean absolute percentage error of 0.554%.
