Interface (moirae.interface)

Interfaces for running common workflows with Moirae, with a particular emphasis on data built with battery-data-toolkit

moirae.interface.row_to_inputs(row: Series, default_temperature: float = 25) → Tuple[InputQuantities, OutputQuantities]

Convert a row from the time series data to a distribution object

Parameters:

• row – Row from the dataset.raw_data dataframe

• default_temperature – Default temperature for the cells (units: C)

Returns:

• Distribution describing the inputs

• Distribution describing the measurements (model outputs)

moirae.interface.run_online_estimate(dataset: BatteryDataset, estimator: OnlineEstimator, pbar: bool = False) → Tuple[DataFrame, OnlineEstimator]

Run an online estimation of battery parameters given a fixed dataset for the

Parameters:

• dataset – Dataset containing the time series of a battery’s performance

• estimator – Technique used to estimate the state of health, which is built using a physics model which describes the cell and initial guesses for the battery transient and health states.

• pbar – Whether to display a progress bar

Returns:

• Estimates of the parameters at all timesteps from the input dataset

• Estimator after updating with the data in dataset
