Battery Pack Modeling

Use the Battery Builder app to interactively create a battery pack with thermal effects and build a Simscape™ model that you can use as a starting point for your simulations.

Create and build Simscape™ system models for various battery designs and configurations based on cylindrical battery cells in Simscape™ Battery™. The buildBattery function allows you to automatically generate Simscape models for these Simscape Battery objects:

Create and build Simscape™ system models for various battery designs and configurations based on pouch battery cells in Simscape™ Battery™. The buildBattery function allows you to automatically generate Simscape models for these Simscape Battery objects:

Uses the test method defined in [1] to characterize a battery cell for electric vehicle applications. First you generate a high pulse power characterization (HPPC) by using Simscape™ Battery™ blocks and an in-built function to derive the battery cell parameters. Then you compare the model to the original battery model under typical drive-profile loading conditions.

How the temperature gradient over the cell surface varies during the fast charging of a battery. Fast charging is one of the key enablers for the adoption of battery electric vehicles. Fast charging pushes a considerable amount of current inside the battery. This process produces a lot of heat. It is important to understand how temperatures spatially vary in a battery and how this affects its long term warranty. Typically, to ensure a good battery life with uniform degradation, the temperature gradient over the cell surface should not exceed around five or six degrees centigrade. This example uses Simscape™ Battery™ to model the cell electrical dynamics and the PDE Toolbox™ to generate the reduced order model (ROM) that describes the battery 3-D thermal model. This example uses a 50Ahr battery (Valance:U27_36XP) and charges it for 10 minutes from an initial state of charge (SOC) of 15%. Then, the example analyzes the maximum gradient in the cell temperature.

Create and build a Simscape™ system model of a battery module with inter-cell heat exchange in Simscape™ Battery™. Inter-cell heat transfer mechanisms are relevant in the design of battery systems, including analyzing battery thermal propagation and evaluating electro-thermal load cycles in virtual verification. The heat transfer mechanisms supported in Simscape™ Battery™ are conduction, convection, and radiation. To create the system model of a battery module, you must first create the Cell and ParallelAssembly objects that comprise the battery module, and then use the buildBattery function. The buildBattery function generates Simscape models for these Simscape Battery objects:

Create and build a Simscape™ system model of a module assembly with a multi-module cooling plate by using Simscape™ Battery™. Large cooling plates that span across several battery modules are quite common in the design of battery systems, including in the automotive and consumer electronics sector. The workflow in this example automates the process of thermally coupling several modules together to a single battery cooling plate. To create the system model of a battery ModuleAssembly, you must first create the Cell, ParallelAssembly, and Module objects that comprise the battery module assembly, and then use the buildBattery function. The buildBattery function generates Simscape models for these Simscape Battery objects:
