Abstract :
It is observed that pulsed discharge currents allow to drain the battery with a higher specific power. Thus they improve the batteries durability and discharge performance. The question is how can the allowed discharge of a battery be modeled. Embedded real-time systems often rely on batteries. For these systems it is necessary to prove both, real-time feasibility and the constraint to not exceed the allowed discharge currents. This paper presents a unified approach for both objectives using the flexible model of event streams, because it allows both to model a complex allowed- discharge curve and the real-time requirements for complex task stimuli. We present the model and the calculation of the allowed and requested discharge curves. Together with the known event- stream based real-time feasibility analysis this allows a unified analysis of both aspects of the system. This work enables the modeling of complex discharge requirements of batteries for real-time systems.
