Battery

This circuit models a Li-Ion (LiFePo4) batteryBased on the following paper:Marek MICHALCZUK1, Bartłomiej UFNALSKI2, Lech M. GRZESIAK2, Piotr RUMNIAK2Politechnika Warszawska, Instytut Automatyki i Robotyki (1), Instytut Sterowania i Elektroniki Przemysłowej (2)Power converter-based electrochemical battery emulatorhttp://pe.org.pl/articles/2014/7/3.pdfStatus: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 &amp; NCELLS_reciprocal_constModify 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: I_meas Rsn_const C1_const R1_const To calibrate for a given cell capacity, Capacity_cell [Ah], modify the parameters according to these relationships: I_meas.K = 1/(Capacity_cell[Ah]*3600[s]) Rsn_const.OUTPUT_LEVEL = 3.1E-3[Ohm]*Capacity_cell[Ah]/40[Ah] R1_const.OUTPUT_LEVEL = 1.9E-3[Ohm]*Capacity_cell[Ah]/40[Ah] C1_const.OUTPUT_LEVEL = 22.75E3[Farad]*Capacity_cell[Ah]/40[Ah]
