compute_bus_conditions

compute_bus_conditions(bus, state, t_idx, delta_t)

Computes the conditions of the bus based on the response of the battery modules.

Parameters:

• bus (ElectricalBus) –

  The electrical bus component with the following attributes:

  • tagstr

    Identifier for the bus

  • battery_moduleslist

    List of battery modules connected to the bus

  • battery_module_electric_configurationstr

    Configuration of battery modules (‘Series’ or ‘Parallel’)

• state (State) – Current system state containing conditions for all components

• t_idx (int) – Current time index in the simulation

• delta_t (float) – Time step [s]

Return type:

None

Notes

This function calculates the electrical properties of the bus based on the connected battery modules. It handles both series and parallel configurations of battery modules.

For series configuration:

• Voltage is the sum of all battery module voltages

• Temperature and energy are averaged/summed across modules

• State of charge is taken from the last battery module

For parallel configuration:

• Voltage is the same as the last battery module

• Temperature and energy are averaged/summed across modules

• State of charge is taken from the last battery module’s cell

The function also handles the fully charged state by setting charging current, power draw, and current draw to zero when the state of charge reaches 1.0.

Major Assumptions

• Battery modules are the primary energy source for the bus

• In parallel configuration, all modules have the same voltage
