  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.

Creating a Circuit

Connect the electrical load to the battery module to create a circuit.

A program file containing the electrical load on the battery is provided.

To create a circuit:

Right-click the Batteries > Program Files node and select Load....
In the Open dialog, select the Tutorial3CDischargeCylindrical.prg file.
Click Open.

The program file that you loaded in the previous step represents an electrical load on the battery. To simulate the response of the battery, the electrical load must be connected to the battery in a circuit. Connect the electrical load using the Circuit Solver tool.

Expand the Circuits > Circuit 1 node.

The Circuit Solver uses Elements and Connections. Each element is either a battery module or a program, and a connection joins elements together in the circuit.

First, you define the battery module and program as elements of the circuit.

Right-click the Battery Modules > Battery Module node and select Create Circuit Element.
Right-click the Program Files > Tutorial3CDischargeCylindrical.prg node and select Create Circuit Element.

Next, the positive and negative terminals of the elements are connected.

Expand the Circuits > Circuit 1 > Circuit Elements node.
Multi-select the Battery Module > (+) Battery Module node and the Tutorial3CDischargeCylindrical.prg > (-) Tutorial3CDischarge.prg node.
Right-click one of the nodes and select Create Connection.
Repeat for the remaining terminals: (-) Battery Module and (+) Tutorial3CDischargeCylindrical.prg.

Each connection is shown under the Circuit Connections node.

To model the effect of ohmic heating, activate the ohmic heating models.

Right-click Batteries > Battery Modules > Battery Module and then select Setup Connector Ohmic Heating.
The Continua > Battery Module Connectors: Ohmic Heating physics continuum node is added with the appropriate models activated.
Expand the Regions node and multi-select the six Battery Module: Tab Connection nodes, and then set the Physics Continuum to Battery Module Connectors: Ohmic Heating.
Save the simulation.
