Description

This block models a battery cooling plate with flat channels. Use the buildBattery function to create a Simscape model of a battery and connect it to one or both sides of the cooling plate. The fluid_in and fluid_out ports are thermal fluid ports. The output ports are the plate temperature, Tp, the fluid pressure drop, dP, and the fluid temperature change, dT.

Build Model of Battery Module Assembly with Multi-Module Cooling Plate

Build Model of Battery Module Assembly with Multi-Module Cooling Plate

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:

Build Model of Battery Pack with Multi-Module Cooling Plate

Create and build a Simscape™ system model of a pack with a multi-module cooling plate by using Simscape™ Battery™ software. Large cooling plates that span across several battery modules are common in the design of battery systems in the automotive and consumer electronics sector. In this example, you thermally couple several modules to a single battery cooling plate. To create the system model of a battery Pack, you must first create the Cell, ParallelAssembly, Module, and ModuleAssembly objects that comprise the battery pack, and then use the buildBattery function. This function creates a library in your working folder that contains a system model block of a battery pack. Use this model as reference in your simulations. You can modify the run-time parameters for this model block, such as the battery cell resistance or the battery open-circuit voltage, after you create the model. To define the run-time parameters, specify them in the block mask of the generated Simscape models or use the MaskParameters argument of the buildBattery function.
