Shift-Left Battery Validation with SIL

Global automobile OEM
Accelerating BMS development through high-fidelity SIL-based modelling

Problem

  • Heavy reliance on hardware and HIL
  • Static models miss real pack behaviour
  • Thermal issues found late in development

Solution

  • High-fidelity FMU with electro-thermal SIL
  • AutoCal parameter identification
  • Defect injection + ageing scenario support

Outcome

  • Enabled SIL-based validation
  • Earlier thermal and degradation validation
  • Faster iterations, less physical testing
Validation scenarios moved to SIL
15+
Faster simulation execution
3X
Effort reduction (ROI)
~35%
Faster time-to-market
20%
