Battery HIL simulator for BMS development and validation
The Desktop BMS™ HIL Test System is perfect for BMS software, firmware, and hardware engineers who need to simulate battery cells and signals for testing a BMS or CMU in a convenient desk- or bench-top location.
This installer packages omits certain components, listed below, to keep the download size small. These components may be downloaded for free from National Instruments. You may install them before or after running the Soft Front Panel Installer.
Diverse Robotics and Autonomous Systems Test Applications Economically Solved by the Latest Universal Test System from BLOOMY.
Reduce your capital expense and time to market with Bloomy’s test as a service!
Until now, validation test of your Battery Management System has required costly and time-consuming development of a custom, one-off test system. Now you can test your BMS at a fraction of the cost and time by using Bloomy’s unique BMS Validation Test Service.
Application Note 8700-0038 provides the factory-recommended safety precautions and simulated cell stack connection topologies for using the Battery Simulator 1200 to simulate high voltage battery packs. For the purposes of this guide, “high voltage” refers to a voltage of greater than ±140V potential from earth ground per IEC610101.
Electrification companies and test labs may now rapidly and economically evaluate multiple BMS designs using conveniently accessible simulated battery and vehicle electronic signals and user-friendly, configurable software.
A Test Engineer's Perspective
During a recent social media post, a reader inquired: "I am interested in your thoughts on MOSFETs (or IGBTs) vs. Contactors in a BMS."
Many EV subsystems are sensitive to the battery performance and behavior throughout the various modes of operation. The drivetrain, inverters, environmental and entertainment controls, ECM and many ECUs all interact with the battery. Subsystem behavior may be effected by the battery’s SoC estimation, SoH, drive cycles, imbalance, ageing, contactor control, alarms and diagnostic trouble codes. These behaviors are difficult, expensive, and often dangerous to replicate in a test lab or track using actual EV batteries.
In this presentation, some considerations with new EV programs are discussed followed by the top 5 (really 7) challenges with developing and testing the battery management system (BMS). A few product demonstration slides are included as well as several practical BMS test solutions.
