Get started

Includes a Molicel P45B cell instance. Ready-to-run, so you can get to know Breathe Model.

Requirements:

  • MATLAB, Simulink & Simscape version R2023b or newer

Features:

  • Operating C-rate range of 10C discharge to 5C charge
    Model performance validated across low to high rate discharge and charge conditions, with additional C-rates and breakpoint fidelity optionally available via extensions.
  • Operating temperature range of 0 °C to 50 °C
    Model performance validated across low and high-temperature conditions, with additional temperatures and breakpoint fidelity optionally available via extensions.
  • Fully validated accuracy
    Fully-validated terminal voltage across the entire operating range of rates and temperatures through comparison to high-quality empirical data (WLTP & constant currrent cycling conditions).
  • Transparent performance
    Transparent accuracy information provided for terminal voltage and for cell temperature with root mean square error and raw data across the entire operating range.
  • Expertly parameterised
    Proprietary, high-quality parameters tightly coupled to the equation system, delivering you ready-to-run models with transparent performance over a clear operating range.
  • Instant access to key battery states
    SOCcell, SOCanode, SOCcathode
    Vcell
    Ucell, Uanode, Ucathode
    φanode, φcathode
    I, Tsurface, Q (heat flow)
  • Define precise degradation levels
    Simulate aged battery behaviour instantly by controlling loss of lithium inventory (LLI) and loss of active material (LAM anode & LAM cathode).
  • Out-of-the-box worked examples
    No painful solver selection or time-wasting settings. Just clear worked examples that help you flexibly develop lower-cost, higher-performing battery systems.
