SIL Platform for BMS VEOS
Short Description
dSPACE's VEOS SIL (Software-in-the-Loop) Platform is a PC-based simulation platform for purely virtual validation of BMS algorithms during the Battery Module Development process, enabling early "frontloading" of testing without the need for physical hardware.

Connor FoleySenior Application Engineer at dSPACE“At dSPACE, we provide comprehensive simulation and validation solutions for Battery Management System development through advanced SIL and HIL technologies. Combining our powerful SCALEXIO platform with our scalable battery emulation hardware and flexible ASM battery model, developers can test the full range of their BMS applications from high precision cell voltage monitoring and SOC calculations, to safety protection mechanisms and balancing strategies. Additionally, our VEOS platform enables seamless SIL simulation of virtual BMS ECUs, creating a continuous workflow from early algorithm development to production-ready validation.”

Specifications & Service
- The VEOS Software-in-the-Loop (SIL) Platform is a high-performance, PC-based simulation environment specifically designed for the purely virtual validation of Battery Management Systems (BMS). It serves as the essential "frontloading" bridge in the Battery Module Development process, allowing engineers to test and refine complex control logic months before the first physical hardware or HIL Systems are available.
- At the core of the solution is the Virtual ECU technology. This allows the BMS production code (C-code or Simulink models) to be executed within a high-fidelity virtual environment. By removing physical hardware constraints, VEOS enables:
- Massive Scalability: Running thousands of virtual test cycles in parallel or within cloud-based environments.
- Risk-Free Fault Injection: Safely simulating extreme failure modes—such as internal cell shorts, sensor drifts, or thermal runaway—without any risk to equipment or personnel.
- Rapid Iteration: Instant deployment of new firmware versions to verify software logic and communication protocols.
- The system integrates seamlessly with dSPACE ASM (Automotive Simulation Models). These open, Simulink-based models provide a transparent foundation for simulating the entire battery system, including:
- State of Charge (SoC) & State of Health (SoH) algorithm benchmarking.
- Cell Balancing Strategies and protection logic.
- Thermal Dynamics and aging effects across diverse cell chemistries (LFP, NMC, etc.).
- VEOS is the industry standard for achieving ASPICE and ISO 26262 Functional Safety compliance at the software level. Because the platform uses the same models and test cases as theSCALEXIO HIL Platform, it ensures a seamless transition from virtual code verification to final hardware-in-the-loop validation.
- Testing is fully streamlined through AutomationDesk, which supports continuous integration (CI) workflows. This allows BMS software builds to be automatically validated against vast test libraries overnight, ensuring that logic flaws are identified early, reducing time-to-market, and significantly lowering development costs.
