Battery Management System Testing

The BMS HIL Demo is a small-scale demonstration of Bloomy’s BMS HIL Test System, an open system platform that hybrid and electric vehicle companies use for firmware development and regression testing of battery management systems (BMS). Learn how you can safely and efficiently simulate the characteristics of advanced Li-Ion batteries and battery systems using NI PXI hardware running VeriStand real-time test software, in tandem with Bloomy’s Battery Simulator 1200 and Battery Fault Insertion Unit.

Hardware-In-the-Loop (HIL) testing is the standard approach to validating the design of xEV ECU systems including the battery management system (BMS) electronics and firmware. HIL test systems are used to simulate the battery including cell chemistry, charging and discharging, drive cycles, and numerous fault conditions for testing the BMS; without the hazards of real batteries, or the cost of prototype vehicles and track time. There exist vendor-defined or “closed”, as well as user-defined or “open” approaches to the implementation of HIL test equipment.

Recorded at The Battery Show 2016 in Novi, MI on 9/14/2016, Bloomy's Peter Blume presents a universal approach to battery management system (BMS) manufacturing test, as well as four manufacturing test best practices. The universal approach utilizes commercial, off-the-shelf (COTS) hardware and software, including Bloomy's own Battery Simulator 1200 and Battery Fault Insertion Unit (FIU) to functionally test the BMS PCBAs prior to assembly in the battery modules and packs. Benefits include higher quality, higher production yields, and fewer defective modules and packs.
