Validating electric drive and battery management systems

February 13, 2013, Off-Highway Engineering Online Article based on SAE technical paper 2012-01-214 written by dSPACE's Jace Allen

Excerpt
"Currently, hybrid and electric drive control systems are being developed for many types of platforms in the aerospace, automotive, and commercial vehicle industries. These systems use battery management systems (BMS), amongst other systems, to handle their demanding power needs.

However, the development of such technologies brings increased system complexity, evident in the platform variants, and even more so in the control algorithms of various electronic control units (ECUs).

Increased system complexity poses new challenges for software design and ECU system validation, mandating the need for simulation tools that can easily handle the inherent system complexity, while providing cost-effective, industry-proven verification tools and processes.

These simulation and testing tools and processes must be capable of providing support for model-based design (MBD) at various stages in the process, from control concept simulation through final target system acceptance. The processes for MBD using model-in-the-loop (MIL), software-in-the-loop (SIL), and hardware-in-the-loop (HIL) must take advantage of synergies in tools used throughout the process."
