Conventionally, the basic cells constituting the multicellular energy storage systems are modeled by electrical schemes based on Thevenin's model. Other, more complex models incorporate the aging phenomena, resulting in a decrease in the State of Health of each cell. All these models remain analytical models and not discrete event systems. In this article, a discrete model is proposed, by detailing how each physical parameter is modeled. It is based on a no-timed Colored High-Level Petri Net. An example of a battery is simulated to validate this theoretical model. Its structure (number of cells) is declined under different architectures (connections between the cells) and is subjected to different resource dynamic allocation strategies. This Petri Net (PN) model makes easy, by adding a sub-network, to simulate different control laws and different resource management algorithms, whether or not allow commutations by forbiding all configurations that do not meet the specification or that will lead to accelerated cell aging. PN is used as a tool for comparing hardware architectures and cell control logic for a battery. Various conventional and innovative architecture are simulate. Different control laws can be compared in terms of performance, as lifespan and use of resources.
