Power converter-based electrochemical battery emulator
This model replicates figure 6 in the above paper, with the addition of modeling a variable number of cells.
The number of cells modeled can be changed by modifying the blocks:
NCELLS_const & NCELLS_reciprocal_const
Modify the values of these blocks to the number of cells and reciprocal of the number of cells, respectively.
The model is calibrated for a single 40Ah battery cell (specifically, WB-LYP40AHA). This 40Ah calibration is represented by parameters values of 4 different blocks:
To calibrate for a given cell capacity, Capacity_cell [Ah], modify the parameters according to these relationships:
