You can use the “buildBattery” function to build custom library blocks from battery objects. It generates one or more custom Simscape library files and a MAT file from the battery object. You can then import the battery objects into the “Battery Builder” App from your workspace or from a MAT file. The steps are as follows:
- Under the Battery Builder tab, in the Import section of the toolstrip, click Import.
- Then click Import from Workspace or Import from MAT-file.
The Battery Builder app typically expects certain inputs, outputs, and nodes to facilitate the simulation of battery packs.
Some of the common I/O are as follows:
- Voltage (V): Your block should output the terminal voltage of the battery. This is essential for monitoring and controlling the battery pack.
- Current (I): The block should accept current as an input, simulating the load or charging current.
- State of Charge (SoC): Providing the state of charge as an output is crucial for battery management systems to track the battery's capacity.
- Temperature (T): Depending on your model's complexity, temperature can be an input (if you are simulating thermal effects externally) or an output (if your model internally calculates temperature changes).
Electrical Nodes:
- Positive Terminal: Serves as the positive connection point for the battery.
- Negative Terminal: Serves as the negative or ground connection point.
