BMS Functional Verification: The Safety-First Approach

In this white paper, we explore the importance of BMS simulation and specifically how hardware-in-the-loop (HIL) offers a safe BMS testing environment, comprehensive testing capabilities, replication of real-world conditions including state-of-charge (SoC) and state-of-health (SoH) functional verification, flexibility, scalability, and time and cost savings.

Some important topics that are covered are top-level functional requirements of BMS verification include voltage, current flow, SoC & SoH monitoring, and thermal management. You will also learn how to create a comprehensive BMS HIL test environment that will provide valuable data, save time, and ensure safety. Understanding the safest way to verify your system using BMS fault testing and simulation. Knowing why HIL simulation is key to success regarding safety and repeatability so you know which HIL switching and simulation modules will help you achieve your BMS verification goals.

Topics covered in the paper encompass BMS Hardware-in-the-Loop Testing, including battery cell simulation, fault insertion switching, charge emulation, COMMS, load emulation, temp sensor simulation, and isolation resistance simulation. Many of the tests required to verify battery management systems (BMS) are too dangerous to conduct in real life as the conditions could result in fire, explosion, or damaging the unit under test.
