Description

This circuit models a Li-Ion (LiFePo4) battery

Based on the following paper:

Marek MICHALCZUK1, Bartłomiej UFNALSKI2, Lech M. GRZESIAK2, Piotr RUMNIAK2

Politechnika Warszawska, Instytut Automatyki i Robotyki (1), Instytut Sterowania i Elektroniki Przemysłowej (2)

Power converter-based electrochemical battery emulator

http://pe.org.pl/articles/2014/7/3.pdf

Status:

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_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:

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]
