Abstract
Nonlinearity of the energy source behavior in portable systems needs to be modeled in order for the system software to make energy-conscious decisions. We describe an analytical battery model for predicting the battery time-to-failure under variable discharge conditions. Our model can be used to estimate the impact of various system load profiles on the energy source lifetime. The quality of our model is evaluated based on the simulation of a lithium-ion battery
