Particle Swarm Optimization Based Battery Parameter Identification

Flow chart and ECM model

Parameter identification of a battery Equivalent Circuit Model (ECM) using Particle Swarm Optimization (PSO). The ECM includes a series resistance R0​, an RC branch with R1 and C1, and a polynomial OCV-SOC relationship. The equations that describe the Equivalent Circuit Model (ECM) are given: The flow diagram takes you through the parameter optimization process. The … Read more

Cell Busbar Thermal Model

cell busbar thermal model

Can we build a quite simple cell busbar thermal model? First thoughts are whether we can make some simple approximations and hence create a spreadsheet model. We have a current [I] flow through the busbar (orange). The busbar has a resistance defined by it’s resistivity, cross-sectional area and length. Hence we can calculate the heating … Read more
