Data Analysis - Save Time & Effort

• Sign in to Batalyse Collect directly from Data Analysis. Instead of creating an access token in Collect’s admin area and pasting it in, Data Analysis opens the Collect login page and establishes the connection for you. Expired or invalid access is detected and the login re-opens automatically.
• Personal access instead of admin access. Each user’s connection is stored under their own name, and a dedicated Monitor User setting lets the Collect Monitor run under a normal user account.
• Several Collect servers side by side:
  • Access is stored per server, so switching between servers that share a user name no longer overwrites each other
  • The server address field is now a dropdown with your previously used addresses
  • The active server is shown in the dialog titles
  • You can log out directly from the batch monitor

• Much more informative error reporting in the batch monitor and the Collect Monitor: the error message, the processing step where it happened, a timestamp and the job type are shown in the Errors column. Error rows can be removed, and stalled or silently crashed background jobs are detected instead of hanging at a fixed percentage.

• Reference-electrode end-of-charge potential: new WE-RE and CE-RE end-of-charge columns with the matching formulas and a new graph, plus a combined WE-CE / WE-RE / CE-RE electrode view.
• Improved BioLogic BCS support with better extraction of the values from the file header.
• Adjustable minimum step current for step detection, for cyclers whose zero-current steps carry a small residual current.

• Uploads and downloads no longer depend on Python. All transfers to and from Batalyse Collect now use a built-in transfer component, which makes transfers more robust on restricted machines.
• Faster comparisons and graph export – data for nested tests is only downloaded when a selected graph actually needs it.
• Units are transferred to Collect as proper characters (superscripts, µ, Ohm), so uploaded summary tables read correctly.
• Better detection of “Info” sheets in Excel-based exports, and step names now include pause steps.
• Exported graph images carry the plot type in the file name.

• Fixes:
  • Row capacity is integrated with midpoint interpolation of the current, and discharge energy keeps its sign
  • Combined charge + discharge comparison graphs showed duplicated legend entries and wrong colours and line styles
  • Continue Import silently imported nothing in some cases and produced empty error reports; capacity and all dependent formula columns are now recalculated for the appended rows
  • Access database import, and header lines with an unusual number of columns
  • Background comparisons that stayed at 0 % or reported no error, and comparisons of comparisons that could not find their underlying tests
  • Collect uploads with numeric or boolean metadata values, duplicate column headers and over-long file names

• Fixed the line-end average voltage, which was calculated incorrectly on Origin 2025 and older.
• Several fixes for direct database imports.
• Licence retrieval retries automatically instead of failing on a single unsuccessful attempt.

• Better EIS comparison plots for tests with only a single cycle.
• Fixed that parameters from one file could overwrite another file’s parameters when several files were configured in the same “multiple files” session.
• Fixed the time column, which was not fully calculated in certain cases on older Origin versions.
• A confusing cycle-selection error message no longer appears when the selection cannot be matched.

• Full reference-electrode analysis:
  • New WE-RE and CE-RE result columns (average potential, polarization and more)
  • DCIR for reference electrodes and new step polarization graphs
  • Reference-electrode graphs are plotted whenever the corresponding standard graph is selected
• Counter-electrode potential offset: an offset can be entered in the Parameters dialog and is applied to all single-test graphs, with axis scales rounded accordingly.

• SOH and further new graphs versus equivalent full cycles.
• BioLogic BCS files are supported.
• Already-analysed tests can be merged – the previous analysis is stripped automatically, so a merge of merges is possible, locally or through Batalyse Collect. A “delete original data” option was added when merging into existing results.
• Uploads to Batalyse Collect are resumable and retry automatically, so large uploads survive a dropped connection.

• Graph labels are fully translated into 10 languages (English, German, French, Spanish, Portuguese, Russian, Korean, Japanese, Chinese, Turkish) – axis titles, DCIR, SOC/SOH/OCV, electrode designations, efficiency, capacity slippage and differential-analysis labels.
• Modernised dialogs with a consistent look, and the exact version (including subversion) is now shown in the dialogs.
• Assign Columns moved into the Parameters dialog, so column mapping is done together with the rest of the test setup.
• Faster analysis through a series of performance improvements, and the file selection dialog now shows all relevant file types.

• Fixes:
  • “Continue Import” – importing new data into an already-analysed workbook works again
  • EIS – comparison graphs no longer error out, legends are correct when multiple EIS data sets are shown, and missing cycle ends are detected
  • Merging files from Collect with differing columns, and duplicate upload errors in Collect
  • Safety-test graphs and the safety-test KPI table upload
  • The pulse comparison summary table and its graphs
  • Compatibility with Origin 2026 – incorrect test-SOC results and a calculation error in certain graphs

• Reference electrodes and extra measurement channels from separate files: additional columns recorded in a second file (for example a reference-electrode or sensor file) can now be linked to a test and analysed together with it.
• Direct import of Maccor and Neware binary files through dedicated connectors, and Arbin Access databases moved to the normal Import button instead of the separate database import.
• Connectors install themselves automatically (CSV, XLSX and others), and are fetched from Batalyse if the OriginLab download fails.

• Circle fit for EIS: the semicircle of the Nyquist plot is fitted automatically and its parameters are written to the results.
• New graphs: CC-CV comparison, CC-CV charge + discharge comparison, additional dQ/dV diagrams including dQ/dV vs. capacity separated into charge and discharge (single test and comparison), and new BST/BTS graphs.
• “Equivalent full cycle” column added to the step data.
• Dark mode for all dialogs, following the Windows system setting.
• Merging of predefined groups from Batalyse Collect, so a group defined in Collect can be analysed as one merged test.

• More accurate device and step-type recognition: better detection of Neware and Maccor files, BioLogic step recognition when the “MD” column is unusable, more reliable identification when current and voltage barely change, and case-insensitive column matching.
• More date and time formats are understood, and files with only two columns can now be imported.
• The licence dialog was reworked, including offline licences.
• Proxy settings are set to “system” automatically when they were previously “direct”, so connections work on managed company networks.

• Fixes:
  • Uploads to Collect failed for file IDs above 10 million
  • Step and test SOC were calculated incorrectly when the negative electrode was selected
  • dT/dV columns and the corresponding graphs were wrong
  • Relative capacity was wrong when “Full capacity cycle” was set to 0
  • The Potential-Current-Temperature graph and the current-density right-hand axis
  • Mean values were wrong when only a single column was selected
  • Data Analysis failed to compile on Origin versions older than 2025

• EIS data from Arbin Excel exports is now recognised and analysed.
• Linking measurement files now happens in the Parameters dialog instead of a separate step, so everything about a test is configured in one place.
• Better recognition of file structures, so more exports are read correctly on the first attempt.
• Faster downloads from Batalyse Collect, with more forgiving timeouts on slow connections, improved Collect sign-in handling and a tidier connection dialog.
• The Basic Parameters section of the Parameters dialog was reworked.

• Fixes:
  • EIS comparisons of more than 8 tests no longer fail
  • “Set all” in the Parameters dialog now applies the values reliably to every selected file
  • Landt files import correctly again, and LVDT / data-logger files import more reliably
  • The default minimum-difference setting for dQ/dV was corrected

• • Data Analysis now automatically installs the proprietary file format connectors for .mpr and .cex files and a python package. You no longer need to manually install or update these connectors when installing or updating Data Analysis. Batalyse plans to add more connectors in collaboration with OriginLab in the coming months.

To enhance data security, we have replaced passwords with tokens. Tokens are now required to connect Data Analysis, Collect, and Mind, as well as to access the API with your own code or third-party software. After updating Data Analysis, Collect, or Mind, you must create and use tokens. Your Collect and Mind login passwords remain unchanged and are still required.

For general information, please watch the basics video, and for detailed instructions, refer to our tutorial video.
