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

Using an ECM to Model HiPot Tests

circuit schematic for HiPot test modelling

Author: Siddharth Kurwa A DC high-potential test (HiPot) is used to detect manufacturing defects in the electrode stack/jelly roll. During the test, a high voltage (orders of magnitude higher than the cell operating voltage) is applied to the cell to screen out early-in-life and latent risks from the production cell population. It is preferred to … Read more
