Project 2 Thermal modeling of battery pack

For a 10 cell series lithium-ion battery model, simulate the thermal effects and compare life cycle performance at various temperatures, charge & discharge rates using MATLAB.

Solution:

Component Requirement:

1. Battery (Table-Based)

to activate the SoC and Thermal Property Click on the battery block then this SIMSCAPE BLOCK will appear then go to simscape block >> Block Choice>> instrumented | Show thermal port

Temperature Sensor

Temperature Sensor

Convective Heat Transfer

Thermal Reference

PS-Simulink Converter: to convert some physical quantity to Simulink data

Electrical Reference

 

Solver Configuration

Scope for output waveform

 

Controlled Current Source for Discharge the battery with some constant discharge current

Simulink model 

 

10 lithium ion cells are connected in series and charging and discharging is done simontaneously.

The temperature sensor are used, there is no heat flow through the sensor. The measurement is positive when temperature at port A is grater than the temperature in port B. The thermal mass is the rate of temperature increase is proportional to the heat flow rate into the material and inversely proportional to the mass and specific heat of material. The solver configuration and electrical reference are connected.
