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

Battery Cell Modelling

The need for modelling The primary reason why one is interested in having a model of a battery is it allows us to make informed decisions, optimise or control a battery to deliver on its intended applications. For instance, we may be interested in knowing how different material choices, electrode compositions or cell packaging, will … Read more
