fastga_he.models.propulsion.components.source.battery.components.perf_entropic_losses module

class fastga_he.models.propulsion.components.source.battery.components.perf_entropic_losses.PerformancesCellEntropicLosses(**kwargs)

Bases: ExplicitComponent

Computation of the entropic losses inside the battery. It represents reversible losses inside the battery and can be either endothermic or exothermic, depending on the entropic heat coefficient and the sign of the current going in or our of the battery, see [CLG17]. The sign convention used here is that the battery discharging means a positive current so the losses will be of the opposite sign of the entropic heat coefficient, see [DFBF16].

Store some bound methods so we can detect runtime overrides.

initialize()

Perform any one-time initialization run at instantiation.

setup()

Declare inputs and outputs.

compute(inputs, outputs, discrete_inputs=None, discrete_outputs=None)

Compute outputs given inputs. The model is assumed to be in an unscaled state.

An inherited component may choose to either override this function or to define a compute_primal function.

Parameters:

• inputs (Vector) – Unscaled, dimensional input variables read via inputs[key].

• outputs (Vector) – Unscaled, dimensional output variables read via outputs[key].

• discrete_inputs (dict-like or None) – If not None, dict-like object containing discrete input values.

• discrete_outputs (dict-like or None) – If not None, dict-like object containing discrete output values.

compute_partials(inputs, partials, discrete_inputs=None)

Compute sub-jacobian parts. The model is assumed to be in an unscaled state.

Parameters:

• inputs (Vector) – Unscaled, dimensional input variables read via inputs[key].

• partials (Jacobian) – Sub-jac components written to partials[output_name, input_name]..

• discrete_inputs (dict or None) – If not None, dict containing discrete input values.
