Information
This scenario explores the temperature dependence for a battery cell.
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.
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.
