Battery: Charge and Discharge Cycles

 

Introduction

This scenario explores the temperature dependence for a battery cell.

In order to get the full experience of this example, you need the following:

 

These pages show an overview of the example. For the full example, open the accompanying notebook Battery.nb.

 

Temperature Impact

Using Mathematica, create plots that compare the first discharge cycle with a discharge cycle after 275Ahs of processed charge for two battery cells: one cell (blue) is kept at 25°C and another (orange) at 50°C.

FirsCycle

LastCycle

As can be seen, the battery cell kept at the lower temperature will discharge for a considerably longer time period.

This model is one of five scenarios using the battery cell. For the other scenarios, see the Battery package.
