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

• Here we use 10 generic battery model with series connection
• the positive terminal is connected with the negative terminal and vice versa

• The power gui block is used here for continuous operation of battery
• It has various mode with discrete, continuous and phasor

• All the battery are created within the subsystem for our convenience

• The ‘m’ terminal of the battery is connected with bus selector
• Bus selector gives the essential data in scope given

• In the battery block we assume the temperature and aging characteristics

• We can assume here the random battery given in the blocks

• The battery is connected with the controlled current source with positive and negative
• The type of battery power supply chosen is AC supply
• The signal generator used here is square wave generator

• It continuously generates square waves at given amplitude at regular intervals
• The ps constant block is used to generate physical signal constant
• This block help in entering the values as in any variable parameter

• The solver configuration is used here because the ps constant is a simscape block
• Ps Simulink converter block is used to convert the physical signal to simscape
• To observe the various thermal characteristics the temperature is changed
• The safe operating range of the battery is 25 C to 40 C is nominal range

• The amplitude of the square wave generator is reduced to half the rated voltage

• By varying the different temperature and Simulation time
• The result we get have different wave forms

Conclusion:

All the models were explained clearly
