Battery Pack Modeling
Simscape™ Battery™ includes MATLAB® objects and methods to automate the creation of Simscape battery models. These MATLAB objects allow you to define your own battery design specifications, visualize your battery in a 3-D space, customize the modeling resolution during simulation, and generate a Simulink® library that contains your custom generated battery blocks. You can use these blocks to assist with virtual battery design and verification, help develop battery control algorithms using Simulink, explore design sensitivities, and design thermal management strategies.
You can develop and test battery control strategies by simulating your custom battery blocks with the blocks in the Battery Management System (BMS) library of Simscape Battery. You can also thermally couple your custom battery models in Simulink with the blocks in the Thermal Management System library. Alternatively, you can define your own custom battery control and cooling system blocks.

Featured Examples
Get Started with Battery Builder App
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.
Build Detailed Model of Battery Pack from Cylindrical Cells
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:
Build Detailed Model of Battery Pack from Pouch Cells

Build Battery Model from Custom Cell Component
Create and build a Simscape™ model of a battery parallel assembly from a custom cell component. To build a battery system, you can either use the cell blocks in the Simscape Battery™ library or use a custom cell component. This approach allows you to use a custom cell component tailored to your requirements to build a battery system.
Design Battery Module for Automotive Requirements
Design a battery module and a cooling plate from battery cell test data. Modular battery units are a good solution to decrease the cost of automotive battery packs. Battery modules can help meet requirements of different customers in similar industry domains. The battery cells are typically parameterized using pulse discharge and charge data. This example uses the hybrid pulse power characterization (HPPC) test [1] to estimate the battery ohmic resistance and other dynamic resistance values.
Inject Faults in Battery Models
Inject faults in battery models during simulations using Simscape™ Battery™ and Simulink® software. First, you explore the effect of disconnecting a battery cell from the other cells of a parallel assembly inside a battery module. A cell disconnection typically happens due to a weld failure or a failure in the cell current interruption device. Then, you add an internal short-circuit fault to a cell of a parallel assembly inside a battery module. The fault triggers a set of exothermic reactions, known as a thermal runaway. You activate both faults during the simulation by using a timed trigger at a simulation time of 30 seconds.
Apply Temperature-Dependent Cell Parameter Variations to Battery Module
Apply temperature-dependent parameter variations to the individual cell models in a battery module generated using Simscape™ Battery™ objects and functions. Modeling temperature-dependent parameter variation is essential for achieving accurate performance predictions, optimizing efficiency, and designing and developing advanced battery systems.
