Exporting Data to Other Tools

The batdata.exporters modules provides tools for writing the data from battery-data-toolkit’s internal format into files suitable for use in other tools.

All exporter interfaces provide a export function which takes the dataset to be written and a path to the directory in which to store the files. The exporter objects themselves take arguments which control how all dataset being exported are written, such as the number of rows per file.

from batdata.exporters.ba import BatteryArchiveExporter

exporter = BatteryArchiveExporter(chunk_size=1000000)
exporter.export(dataset, 'output_dir')

Note

We assume each dataset will be stored in its own directory, but that’s not a decision we won’t revisit.

BatteryArchive

The BatteryArchive project stores battery data in an SQL database. Our exporter does not connect to this database and, instead, writes each battery dataset into files with column names that match BatteryArchive’s SQL schema so that adding them to the archive is simple.
