Steps of Circuit Building

The following circuit is build by the 10 cells arranged in series which has electrical components to its left side and the thermal components to the right side.The components like PSConstant, Electrical Reference,Ametter,Solver Configuration and Controlled Electrical Source are those electrical components and the Temperature Constant, Convective Heat Transfer, Thermal Reference and Temperature Source are those thermal components. In this case the SOC of the entire pack is calculated by the method of Coloumb Counting. It uses the discharge current to calculate SOC. Here a 4.5V battery pack is used so it is discharged from 100 to 0 in an hour.The formula representation is :

SOC = 1 - ∫ I / Maximum Capacity of the Pack

The values of SOC and TEMP are bought in to the scope by the means of GoTo and From.

Plot results

Considering the plots they were all plotted with the various intial temperature source reading like 300K,350K and 450K all gives similar graphs for SOC and TEMP.

The value of Temperature increases 298.1500K to above 298.1515K whearas, the valu of SOC decreses from 1 to 0.
