aurora_neware 0.2.3

Python API for Neware Battery Testing System

A standalone Python API and command line interface (CLI) to control Neware battery cyclers.

It is designed for BTS 8.0 and WHW-200L-160CH-B systems, and should work on other cyclers using BTS 8.0.

Features

• CLI and Python API
• Connect to Neware cyclers
• Retrieve status, data, logs
• Start and stop experiments

Installation

Install on a Windows PC with BTS server and client 8.0, connected to one or more Neware cyclers with the API activated.

With Python >3.10, run:

pip install aurora-neware

[!IMPORTANT] Your BTS software must have the API activated, accessed with Help -> Mode settings.

You may need to contact Neware for an activation key.

CLI usage

See commands and arguments with:

neware --help
neware <COMMAND> --help

E.g. to check the status of all channels use:

neware status

To start a job use:

neware start "pipeline_id" "my_sample" "my_protocol.xml"

A pipeline is defined by {Device ID}-{Sub-device ID}-{Channel ID}, e.g. "100-2-3" for machine 100, sub-device 2, channel 3.

API usage

Commands are also available through Python, e.g.:

from aurora_neware import NewareAPI

with NewareAPI() as nw:  # connect to the instrument
    nw.start(
        "pipeline_id",
        "my_sample",
        "my_protocol.xml",
    )
