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 ▸
SOC_cell, SOC_anode, SOC_cathode
V_cell
U_cell, U_anode, U_cathode
φ_anode, φ_cathode
I, T_surface, 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.

Frequently Asked Questions

From end of the business day on which we receive your purchase order.

If we receive your purchase order on non-working day in the UK, the lead time is considered from the end of the following business day.
We love to hear it. Drop us a message and let us know what you’re looking for. We’re always developing our models and, like you, we’re eager to do more state estimation.
Simulation is successful when it can provide useful answers. With today’s state-of-the-art in battery technology and modelling, there’s an inflection point in the usefulness of answers that’s passed when one can parameterise physics-based equation systems using physical cell materials. We believe all of our customers deserve that level of useful answer, so we routinely perform parameterisation on a wide range of cells, off-the-shelf and extremely custom, from around the world.
