Why teams use Breathe Simulate

Predict earlier

  • Predict electrical and thermal behaviour across operating conditions.
  • Assess ageing and degradation behaviour before large test campaigns complete.
  • Expose internal states linked to degradation mechanisms.

Integrate faster

  • Run studies directly through the Breathe Simulate Python API.
  • Export to MATLAB/Simscape workflows for module, pack, and controls studies.
  • Keep one data flow from model delivery to engineering decisions.

Reduce programme burden

  • Cut redundant lab work where simulation confidence is validated.
  • Focus physical testing on non-redundant, decision-critical cases.
  • Improve development agility without weakening technical rigor.
