BioLogic BT-Lab® Software Suite for Battery Cyclers (BCS-series)
BT-Lab® Suite: From reliable tests to efficient analysis
Effortless Battery Cycling and Automated Batch Data Analysis
The BT-Lab® Software Suite simplifies battery cycling with its user-friendly interface and adaptable design.
Uncompromising Reliability: Embedded BT-Test™ continuously monitors experiments, ensuring consistent and accurate results.
Powerful Data Analysis: BT-Analysis™ software streamlines the process, allowing for rapid and insightful interpretation of complex data sets based on user-defined settings.
Built for Batteries: The software includes essential features like native EIS, providing researchers and engineers with comprehensive tools to gain a deeper understanding of battery behavior and performance.
BT-Test™
BT-Test™ acts as the central hub for designing, running, and monitoring battery testing experiments. It provides a user-friendly interface to configure various testing techniques, including:
- Constant Current / Voltage / Power / Load
- Voltage / Current Scan
- DCIR (Direct Current Internal Resistance)
- G-ACIR (Galvano Alternating Current Internal Resistance)
- Galvano / Potentio EIS
- Loop (up to 4 loops possible)
- Rest
- Up to ten variables in the CALCULATE task
- Arbitrary User Profile (AUP)
- 128 steps
- Up to 4 limits per step
- Up to 4 recording conditions per step
BT-Test™ allows for complex testing profiles with up to 128 steps, each containing 4 user-defined limits and 4 distinct recording conditions. It also offers real-time data access and monitoring, enabling researchers to “modify on the fly” any running experiment or dynamically adapt tests based on measured values and pre-defined variables. This flexibility ensures experiments are optimized to gain deeper insights into battery behavior.
Testing Center
Efficient battery testing is empowered by unparalleled flexibility, featuring intuitive Test Run setup, real-time data visualization, and remote access capabilities. Users can effortlessly create and run cycling tests, automatically generating graphs for immediate insights into battery performance. They can even modify test plans on-the-fly based on real-time measurements.
With three types of variables (User Variables, Task Variables, and DUT Parameters), values are calculated at the end of each task or loop and adapted based on up-to-date measurements. Up to three experimental limits can be set on measured values such as time, current, voltage, temperature, or variations thereof. Different actions may be triggered when a limit is reached, such as “stop” the experiment or “go to sequence N”. Additionally, safety limits can be added to each channel to shut it down in the event of an anomaly.
Lab Manager
Managing channels, users, and instruments is simple, with easy filter options to quickly view DUT Run status, user activity, and system messages.
Data Manager
Easily select and manage data for analysis and export.
Global View
Monitor all channels simultaneously on an advanced Global View. The status of each channel is displayed with color-coded indicators to provide quick, informative visual feedback.
EIS Capability
The BCS-900 series Battery Cyclers include the capability for Electrochemical Impedance Spectroscopy (EIS) measurements on every channel, covering a frequency range of 10 mHz to 10 kHz in both potentiostatic and galvanostatic modes. With native EIS, the entire testing process—from setting parameters to data acquisition and analysis—can be performed within a single platform. This improves efficiency and reduces the risk of errors during data transfer between instruments.
BT-Analysis™
BT-Analysis™ simplifies the process of analyzing large datasets from battery cycling experiments. It can import data from multiple tests simultaneously and apply the same analysis to each dataset using the Recipes tool for consistent and efficient evaluation. These Recipes automate common analytical tasks, saving time and ensuring reproducible results.
BT-Analysis™ generates clear and informative outputs, including visually appealing graphs that facilitate comparison between different battery tests. Additionally, it automatically creates comprehensive tables that can be easily filtered by cycle, loop, or step to identify trends and specific data points of interest.
Boards
Battery testing generates enormous amounts of data. Thanks to BT-Analysis™, researchers can streamline data processing and statistical analysis. Boards is a user environment designed specifically for battery applications, focusing on visualization—including graphs, tables, and statistical tools. With intuitive navigation, users can customize graphical and tabular representations to fit their needs. Battery plot comparisons become more effective with the ability to visualize and filter process values by cycle, loop, or step, simplifying cell comparisons across systems and previous tests.
Recipes
The Recipe feature makes batch data processing automatic. With just a few clicks, graphical or tabular data across hundreds of Test Runs can be generated, ensuring quick and decisive action when it is a must.
Test Reporting and Export
The ultimate goal of analysis is to share data with others. Whether through manual or automatic processes based on Recipes, BT-Analysis™ data can be easily formatted and used for professional reporting.
