plot_battery_module_C_rates#

plot_battery_module_C_rates(results, save_figure=False, show_legend=True, save_filename='Battery_Module_C_Rates', file_type='.png', width=8, height=6)[source]#

Creates a two-panel plot showing instantaneous and nominal C-rates of battery modules during operation.

Parameters:

  • results (Results) – RCAIDE results structure containing segment data and battery conditions

  • save_figure (bool, optional) – Flag for saving the figure (default: False)

  • show_legend (bool, optional) – Flag for displaying plot legend (default: True)

  • save_filename (str, optional) – Base name of file for saved figure (default: “Battery_Module_C_Rates”)

  • file_type (str, optional) – File extension for saved figure (default: “.png”)

  • width (float, optional) – Figure width in inches (default: 8)

  • height (float, optional) – Figure height in inches (default: 6)

Returns:

fig

Return type:

matplotlib.figure.Figure

Notes

The function creates a 1x2 subplot showing:

  1. Instantaneous C-rate vs time

  2. Nominal C-rate vs time

Different segments are plotted with different colors using the inferno colormap. For multiple battery modules, only non-identical modules are plotted.

Major Assumptions

  • For identical battery modules, only the first module’s data is plotted

  • Time is converted from seconds to minutes for plotting

  • Battery energy is converted to Watt-hours for calculations

Definitions

‘C-rate’

A measure of the rate at which a battery is discharged relative to its capacity

‘Instantaneous C-rate’

C-rate calculated using the current battery capacity

‘Nominal C-rate’

C-rate calculated using the maximum battery capacity
