Abstract
Optimizing energy consumption of a portable system directly affects the discharge current drawn from the battery. Since battery life ends when the battery voltage drops below a certain cutoff value, modeling the voltage-current relationship is important to system designers evaluating the impact of various design alternatives on the battery life. This paper presents a model that can accurately predict the battery voltage given current over time. Modeled phenomena include battery capacity loss at high discharge rates, charge recovery, and capacity fade with time.
