State of Charge (SOC) Equations for Battery and Supercapacitor Blocks

9 views (last 30 days)
Hello, I am using battery (Lithium-Ion) and supercapacitor blocks from the simulink library (Simscape/Electrical/Specialized power systems/Sources) . Where can I find the relationship between SOC(t) and SOC(t+1) for these energy storage systems? Thanks.

if you right click the blocks, you can look under the mask and expore the full implementaiton of the models mathematically. You can also look at the doc page. If you want to store the two different values in your simulation, you can use a unit delay and compare that to the original signal to compare t and t-1. To get t+1 you would have to estimate it, so hopefully the relationship between t and t-1 is good enough.
