How it works

Breathe Model is a physics-based desktop battery model. Its physics-based structure provides deeper insight into battery kinetics and dynamics, for example, by revealing anode and cathode potentials during use.

We designed the tightly coupled model framework and parameterisation process synchronously. The result is a simulation product and delivery process that scales to meet the volume and velocity needed to support your product portfolio development and unique battery needs.

Breathe Model validation

Validated results.
Transparent accuracy.

Breathe Model is delivered with clear, validated accuracy bounds, so engineers know the context of their simulation results - every time. Model validation reports are shared with full transparency of performance over the entire range the model was parameterised for, showing where it excels and where its limitations lie. We also share equation descriptions (except for core IP) and make OCV, geometric and particle parameters available.

This transparency reduces uncertainty, supports faster, more confident decision-making, and eliminates the need for repeated empirical verification, letting you simulate with confidence.
