Hybrid electric vehicle power management strategy including battery lifecycle and degradation model

The following work is concerned with the inclusion of battery degradation mechanisms in power management strategies applied to current-generation hybrid electric vehicles (HEV). Using a real, physical electric vehicle as a basis for validation, a simulation model was realized to describe the behavior of the HEV and its components, including a lead-acid battery bank, an internal combustion engine (ICE) generator and a polymer electrolyte membrane fuel cell (PEMFC). This model is to be used in conjunction with a newly developed battery degradation model and included as part of a power management strategy aimed at reducing operating costs via an associated function, with the objective of studying the effects of battery lifecycle in such a strategy. As a first step towards the realization of this goal, this paper is aimed at describing the model of the HEV and its validation.
