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
Building on the Tesla fast charge thermal model that was discussed in the Siemens post: Race to the clouds: Battery thermal behavior simulation of a Tesla Model 3. This article looks at the cooling system and impact of a change in cooling direction. Starting with the model and the original Fast Charge Scenario. Fast Charge … Read more
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
