  The tutorials in this set illustrate various Simcenter STAR-CCM+ features for setting up a battery model:
  - Electro-Thermal Modeling: Battery Pack Cooling
    The design of battery pack thermal management is critical in order to ensure that the battery pack operates in a safe temperature range. The objective is to prevent any part of the pack from overheating or from operating in too low temperature conditions. If the battery pack is not sized accordingly, the temperature can accelerate its aging, create an imbalance of the modules and cells in the pack, or lead to hazardous situations.
  - Thermal Runaway: Battery Pack Heat Release and Venting
    Thermal runaway in batteries occurs when a battery cell overheats due to thermal or mechanical failure, short-circuiting, or overcharging/over-discharging. At elevated temperatures, the battery cell materials can start to decompose in exothermic reactions, leading to self-heating behavior. When the self-heating of the battery cell exceeds the rate at which heat can be dissipated to the surroundings, the cell temperature rises exponentially, the battery structure can rupture, and all remaining thermal and electrochemical energy is released to the surroundings.

Setting Up Tab Connections

Set up tab connectors to define the connection between the positive and negative tabs of the battery cells.

A physical connection between the positive and negative tabs of the battery cells can be modeled using tab connectors. For a regular formation of cells, a single tab connector can be used, and Simcenter STAR-CCM+ uses copies of the connector to join all the tabs in the battery module. A simple tab connector has been prepared for this tutorial.

To set up tab connectors:

Select File > Import > Import Surface Mesh from the menu bar.
In the Open dialog, select the tabConnector.x_b file.
Click Open.
In the Import Surface Options dialog, Click OK.
The default import surface options are appropriate for this tutorial.

The imported geometry consists of 3 parts: a positive post, a negative post, and a strap. These parts are added to the Geometry > Parts node in the Simcenter STAR-CCM+ tree.

Use the imported tab connector parts in the battery module definition.

Right-click the Batteries > Battery Modules > Battery Module > Tab Connections node and select Setup Tab Connections.

The Setup Tabs Connections in-place dialog appears.
Set Connections Setup Method to Copy Single Tab Connector.

The positive tab of the first cell in a string of cells that are connected in series generally becomes the positive terminal for the battery. Similarly, the negative tab on the last cell in a string of cells that are connected in series becomes the negative terminal for the battery. This means that the positive tab on the first cell and the negative tab on the last cell in the series remain open when the tab connectors are added.

The tab connector parts are assigned using the First Post Parts, Strap Parts, and Second Post Parts options.

In the First Post Parts property, click (Custom Editor).
In the Set Connection Geometry Parts dialog, select Tab Connector: -ve.
Click OK.
Set the Strap Parts to Tab Connector: Strap.
Set the Second Post Parts to Tab Connector: +ve.

The completed dialog is shown below:
Click Apply, then click Close.
