Fault injection of a battery pack

Hi,

I have build a bettery pack with the batteryBuilder app the configuration as follow: module:14s14p, battery pack; 1s5p, now I want inject fault to short circuit one cell, however the battery model can't go down to cell level, which means I can't physically short circuit it with a resistor, and i can't find fault injection options like with a 'Battery Equivalent Circuit'. How can I implement this?

Hi Ye,

The Battery Equivalent Circuit block is the battery block that supports fault injection, such as short-circuit faults.

Therefore, by building a battery object based on Battery Equivalent Circuit block, you can create a Simscape model that allows for fault injection.

Specifically, in the BatteryBuilderApp, you can generate a cell object based on the Battery Equivalent Circuit block by setting the CellModelBlockPath within CellModelOptions to batt_lib/Cells/Battery Equivalent Circuit in the Properties screen of the cell object.

Using this cell object, you can then create Parallel Assembly and Module objects, allowing you to build a battery model that supports short-circuit fault injection.

Thank you, this is helpful.
