Název v původním jazyce

Complex traction battery model

Popis výsledku v původním jazyce

The outcome is a configurable electrical simulation platform for traction battery packs, capable of representing virtually any cell interconnection architecture (series/parallel groupings, modules, and parallel strings). The platform supports both identical-cell simulations and cell-resolved modelling to capture cell-to-cell variability caused by manufacturing tolerances and operational ageing. Individual cells are described by SOC-, temperature-, and SOH-dependent equivalent circuit models (OCV source, series resistance, and two RC branches), with optional inclusion of busbar and joint resistances. A simplified Battery Management System (BMS) model is integrated to represent operational limits, balancing behavior, permitted disbalance, and voltage-dependent self-consumption, enabling realistic assessment of pack behavior under dynamic current profiles. For dissemination and direct use, a MATLAB-based application with an English graphical user interface is provided, including predefined profiles (e.g., WLTC, DDP), import of custom cell/BMS models, and export of results. In utilization, the platform supports model-based development and model-in-the-loop workflows. It is suitable for comparing cells across chemistries and manufacturers, developing and calibrating BMS algorithms, predicting cell behavior over lifetime, and performing vehicle-level design optimization; it is also applicable beyond automotive to other lithium-ion-based electrochemical power sources, with expected reductions in early SW development and calibration effort for key battery functions.
