Redesigned cell page

Cell pages — full redesign:

New layout — image, headline metrics and description on one screen, with tooltips on every figure
Simulate preview showing expected results for two example pack configurations
Similar cells — mini Ragone chart against comparable cells of the same format
Manufacturer profile with company background and a get-in-touch link
Non-simulatable cells no longer show a misleading status badge

Onboarding:

Beginner tour

Voltt Docs:

New Supported Platforms page — requirements for Simscape, Simulink and Python
Homepage model panel rebuilt as a family selector, ready for more models
Toolbox signposted in the platform panel, calculators coming soon
Tighter layout — more on screen, with sidebar and contents collapsing on narrow windows
Single sign-on — log into the Voltt once, gated docs pages open straight away

A fresh coat of paint on the Voltt Docs homepage and documentation site.

Homepage Redesign

Homepage redesign:

New two-panel product layout — The Voltt Platform and The Models side by side
Feature rows with icons for Cell Library & Compare, Simulate and Powermap
Model tiles for ECM, Thermal, Electrochemical and Degradation with descriptions
What's new section linking to latest release notes
Sequential Next navigation across all product pages

Copy & content:

Updated product descriptions — clearer distinction between cell selection and pack design
Restructured model descriptions: what it is · application
Version history now in descending order across all model docs

New features:

Added Simulate as Pack — virtual pack topology support for cell-only simulations, including sweep handling
Added CC-CV / CV hold support, SOC min/max termination, and voltage limit handling
Added a guided tutorial flow for new Simulate features

Guided Tutorial Flow

Improved duty cycle management with a new save step and cleaner create/edit flow

Improvements:

Simulate/Powermap backend overhauled — significantly faster and more reliable
Powermap now runs parallelised — much quicker results
Fixed Powermap reliability issues around slice handling and result rendering
ECM binary updates with improved warnings, errors, and better partial-result handling
UI improvements for simulation inputs

Fixed Simulate Fixed Rate y-axis label not showing for Power
Updated Simulate limit warnings to include pack limits
Fixed Error logging for Simulate — failed simulations no longer count towards token usage
Updated dashboard articles and Highlighted Cells
Fixed Datasheet URL link
Increased Image Export resolution (DPI)
