Battery systems are complex. They span electrochemistry, thermodynamics, and mechanics, interacting across multiple spatial and temporal scales. Traditional experimental methods relying on time-consuming empirical testing are no longer enough to keep pace with today’s performance demands and rapid development cycles.

That’s why simulation is essential. But not all battery modelling approaches are created equal.

At Breathe, we built our modelling pipeline around a physics-based framework - not because it’s simpler, but because it delivers the accuracy, scalability, and real-world relevance our customers need. And we didn’t stop at building accurate models - we industrialised the process to make it fast, repeatable, and commercially deployable.

In 2024 alone, our team delivered a new, fully parameterised battery model every 2.5 weeks - within just 4 weeks from cell receipt to model delivery. This whitepaper explains exactly how.
