How simulation helps battery teams make durability decisions sooner
Battery ageing tests take months. Critical programme decisions including architecture and control strategy can’t wait that long. The result is teams that commit to system design before they have evidence of how their cells actually age.
In this on-demand webinar, Oskar Nordlander (Product Manager) and Jishnu Ayyangatu Kuzhiyil (Battery Degradation Model Developer) from Breathe walk through how to:
- Understand why durability decisions are structurally hard to make early in development programmes
- Build and validate a physics-based degradation model on your own cell and data
- Use simulation to focus ageing test matrices and cut redundant protocols
- Predict how the same cell ages differently across real-world use cases and pull durability decisions forward

What you’ll learn in this session
- How durability decisions are shifted earlier in the development process
By the time an 18-month ageing campaign completes, architecture and control strategy are already constrained. Physics-based simulation breaks that dependency: instead of waiting for degradation tests to finish, you can get predictive insights and act on it months earlier.
- How the same cell ages very differently in the real world
A driver in Arctic Sweden, a daily fast-charger on the Autobahn, and a retiree parked in Arizona heat each put the same cell on a different degradation path. Simulation makes every use case visible.
- How to cut 30–50% of your test allocation without losing confidence
A typical 200-cell validation programme runs to £3M and 180 cumulative years of test time. Model-guided test design can reduce cell count to 100–140 while improving the quality of insight.
- What the model delivers for each team in your organisation
Battery engineers get early ageing predictions and visibility into internal ageing pathways. System engineers get a drop-in model for lifetime BMS tuning. Programme leads get quantified warranty exposure and decisions that don’t wait for full test completion.
Who this webinar is for
- Modelling, simulation, and validation engineers
- Cell and battery development engineers
- System and BMS engineers working on ageing-aware controls
- Programme managers and commercial leads responsible for durability milestones
See Breathe Simulate in action
In the demonstration, you’ll see how Breathe Simulate helps you:
- Start from a parameterised commercial cell such as the Molicel P45B
- Conduct sensitivity analysis on cell parameters
- Quantify the impact of parameter variation on performance and degradation
- Simulate degradation modes such as LLI and LAM
- Evaluate how ageing shifts thermal and fast-charging limits
- Translate cell-level behaviour into system-level battery insight
Want to go deeper with your own cells?
If you want to evaluate your own cells using this workflow, Breathe offers:
- Cell parameterisation
You send 10 cells. Breathe performs teardown, characterisation, parameterisation and validation.
Your cell models then become available inside Breathe Simulate.
- Co-design studies
Work with Breathe to build early insight into degradation pathways and their system-level impact, stress-test control strategies against aged cell states and inform system, control, and vehicle-level battery decisions
A typical PoC completes in weeks, not months.
