Difference between generic battery bloc and battery table-based (Thermal management)

Hello,

I'm actually trying to simulate heat generation from a lithium-lion 18650 battery but I would like to know the differences between the generic battery bloc and the battery table based ? Which one should I use for this application ?

I have MATLAB R2022b, simcape electrical and simscape battery installed.

All of the blocks you mention can be used to model a Lithium Ion 18650 Battery.

1. The Battery block is based on an equivalent circuit and requires the fewest parameters. It can be used to represent any battery chemistry. Use this block if you only have a basic characteristic you wish to represent.
2. The Battery (Table-Based) block is based on an equivalent circuit and uses lookup tables to match battery characteristics. It can be used to represent any battery chemistry. Use this block if you are trying to match a characteristic directly from a datasheet. This block is used within the battery pack models produced by Simscape Battery.
3. The Generic Battery Model block uses Simscape Specialized Power Systems technology, and uses unique equations for the specific battery chemistry types it supports. Use this model if you are building electrical network models using Specialized Power Systems technology.
