With the adoption of electric vehicles in the automotive and aerospace industries, a significant challenge to be tackled is the effective testing and validation of the battery management system (BMS). Using modular, PXI-based switch and simulation modules offers many advantages in testing a BMS including:

• A fully flexible test system that can be optimized to meet exactly what is needed and can be easily modified to address evolving requirements
• An industry-standard open architecture that promotes system longevity and mitigates obsolescence while providing seamless integration of multi-vendor instrumentation and communication modules

This session examines the advantages of combining a multi-cell battery emulator with PXI switch and simulation modules such as high-voltage switching, fault insertion, and thermocouple and RTD simulation, as well as a CAN bus interface, to create a fully flexible BMS test system.
