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]

Description

This circuit models a LiFePO4 cell voltage.

Based off of the model described in:

Liao Chenglin; Li Huiju; Wang Lifang, "A dynamic equivalent circuit model of LiFePO4 cathode material for lithium ion batteries on hybrid electric vehicles," Vehicle Power and Propulsion Conference, 2009. VPPC '09. IEEE , vol., no., pp.1662,1665, 7-10 Sept. 2009

doi: 10.1109/VPPC.2009.5289681

This is a model that describes the relationship between open circuit voltage and the state of charge of a battery under different temperatures. A net list to describe the different chemical, electrical, and mechanical components of the system are under the component "Battery_Pack". Input from a supplemental Excel Spreadsheet (provided upon request) can be implemented into the model to characterize the behavior of Market EV's for simulation purposes. Heat sinks are included in the circuit model for the Pack, Stack, and Cell to help provide accuracy for heat generation rates. The Tafel Equation (derived from Buttler-Volmer) is implemented to more accurately model the mass transport, ohmic, and polarization losses in the polarization curve.
