dSPACE Outlines Scalable Path for Battery Management System Testing

dSPACE has detailed a strategy for scaling battery management system (BMS) testing across a widening array of electric applications, introducing an entry-level Hardware-In-the-Loop (HIL) solution designed for smaller, lower-voltage systems.

What Happened

The company’s new SCALEXIO Battery HIL – Essential is positioned as a compact, cost-efficient starting point for teams developing BMS units for light electric vehicles, mobile robots, forklifts, drones, and power tools. The system targets approximately 200 V class applications and supports up to 64 cell voltage channels. It is designed to replace physical battery packs with controllable real-time simulation, allowing engineers to validate core BMS behaviors such as cell voltage measurement, temperature inputs, state estimation, and balancing logic without the risks and costs associated with live battery testing.

Why It Matters

As BMS technology moves beyond high-volume passenger EVs into diverse sectors like stationary storage and industrial automation, development teams often face tighter schedules and fewer dedicated test engineers. Traditional bench testing struggles with repeatability and fault insertion, while fully customized HIL systems can be prohibitively complex and expensive for smaller projects. By offering a standardized configuration with shorter delivery times, dSPACE aims to remove entry barriers for these smaller programs, enabling them to adopt rigorous simulation-based validation early in the development cycle.

The Bottom Line

dSPACE’s approach provides a scalable framework where teams can begin with the Essential configuration and migrate to predefined or fully customized SCALEXIO Battery HIL systems as their battery architectures grow in voltage and complexity.
