概要
Hands-On Demo with dSPACE Tools
Discover how you can seamlessly transition from software-in-the-loop (SIL) to hardware-in-the-loop (HIL) testing for battery management systems (BMS) in this hands-on demonstration.
Using a real-world example of a BMS for a low-voltage scooter, this tutorial guides you through the following topics:
- Real-time testing with dSPACE SCALEXIO
- Virtual ECU integration via VEOS
- Automated regression testing with AutomationDesk
- Undervoltage fault detection in both virtual and real ECUs
- Seamless reuse of test cases across environments
What you will learn in this video:
- How to validate BMS firmware in both virtual and real environments.
- How to automate test cases to ensure repeatability and efficiency.
- How to interpret test results and error messages for safety-critical systems.
This video demonstrates how dSPACE tools can help streamline your BMS validation workflow – from simulation in the early development phase to testing with real hardware.

FAQs
Q1: What is the main benefit of bridging SIL to HIL testing?
A1: It allows early validation of ECU software in a virtual environment and seamless transition to real hardware tests without rewriting test cases, improving development efficiency and reliability.
Q2: How accurate is the battery cell voltage emulation in the HIL setup?
A2: The system uses high-end hardware capable of 0.3 millivolt accuracy with galvanically isolated power supplies for precise and safe signal generation.
Q3: Can this setup test production-level ECU firmware?
A3: Yes, the virtual ECU includes application and basic software components, enabling testing close to production code.
Q4: How does automation improve the testing process?
A4: AutomationDesk enables repeatable, block-based test cases with automatic execution and reporting, reducing manual intervention and increasing test consistency.
Q5: Are other battery-related test cases supported besides undervoltage testing?
A5: Yes, tests for cell overvoltage, cell balancing, and pre-charge circuit functionality are also supported within the same framework.
Q6: Can this testing approach be adapted to other vehicle types?
A6: While demonstrated on a low voltage scooter, the methodology and tools are applicable to a wide range of battery management systems in automotive and other sectors.
