Abstract :
Once the battery becomes fully discharged, a battery-powered portable electronic system goes off-line. Therefore, it is important to take the battery behavior into account. A system designer needs an adequate high-level model in order to make battery-aware decisions that target maximization of the system´s lifetime on-line. We propose such a model: it allows a designer to predict the battery time-to-failure for a given load and provides a cost metric for lifetime optimization algorithms. Our model also allows for a tradeoff between the accuracy and the amount of computation performed. The quality of the proposed model is evaluated using a detailed low-level simulation of a lithium-ion electrochemical cell.
