Thermal Management

Characterize the thermal runaway behavior of a battery cell by simulating an accelerating rate calorimetry (ARC) test.

Create and build a Simscape system model of a battery module with thermal effects.

Evaluate a new and end-of-life (EOL) lithium-ion battery pack. With cell usage and time, the capacity of the cell degrades and the resistance increases due to the formation of a solid-electrolyte-interface (SEI), a passivation layer over the anode surface. You must design battery pack components to meet warranty criteria at EOL time from power, performance, and packaging perspectives. This example analyzes a 400V battery pack for EOL thermal performance based on its packaging.

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:

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.
