Project 2

a. Maximum heat generation of the battery.

Maximum heat generated= Joule heat+ Entropic heat

Joule heat= Isquare*R*t

=-0.896 square*0.5milli*120

=48.17milli Joules.

b. SOC of the battery

To find the SOC of the battery Matlab simulink is used and a model comprising of battery, controlled current source and signal builder is used. All the models are connected as shown below

The SOC from the battery is obtained from the scope as shown below

The SOC of the battery at 2*104 seconds is obtained from the graph and its value is 98.9
