A structured approach inspired by test bench calibration
A successful and efficient vehicle calibration process builds on well-known principles from test bench calibration. TOPEXPERT adapts these principles to vehicle calibration with a structured approach.
Core steps of the calibration process:
- Structured Test Planning: Clear and reproducible planning logic to support vehicle calibration campaigns
- Automated Test Execution: Efficient execution logic aimed at ensuring high-quality measurement data
- Data Analysis and Optimization: Results analysis and iterative optimization during test campaigns
- Validation and Verification: Final validation under representative test conditions
xCAL: Design of Experiments (DoE) for automotive calibration
The xCAL module enables the application of Design of Experiments (DoE) methods to automotive calibration use cases.
Optimization with fewer test runs
xCAL helps engineering teams:
- Explore multi-parameter calibration spaces efficiently
- Reduce test effort while maintaining modeling and identification quality
- Address complex objectives such as minimum energy consumption
Use case: Battery electro-thermal and ageing
TOPEXPERT and xCAL are well suited for battery and BMS-related calibration and modeling tasks.
Battery parameter identification using DoE
- DoE testing and modeling for parameter identification of the Equivalent Circuit Model (ECM) as part of a BMS
- ECM parameter response can be highly non-linear with respect to temperature and SOC variation
- Battery parameter identification includes Rx, Cx, Lx, …
Integrated electro-thermal battery modeling
- Sub-model integrated into an electro-thermal battery model
-
Model outputs can include:
o Voltage
o Temperature
o Battery ageing parameter identification
