Battery Management System Testing

Learn about BMS test techniques using commercially available cell simulation hardware that increase safety, efficiency, repeatability and coverage

Many battery energy storage system (ESS) manufacturers and consumers utilize live cells for testing electronic subsystems, including the battery management system (BMS). There are issues with this approach in the various stages of battery system design, development and production. In this paper and presentation, Peter Blume discusses BMS test techniques using commercially available cell simulation hardware.

 

Bloomy's Battery Test and Simulation Unit Manager, Steven Hoenig and Maplesoft's Vice President of Engineering Solutions, Paul Goossens present on model-based battery management systems (BMS) testing as a safe and efficient alternative to the more traditional approach of using physical battery cells.

View this webinar to learn how by combining MapleSim’s high-fidelity battery models and the Bloomy BMS HIL Test System, it is now easier to safely and efficiently test and develop advanced BMS firmware for enhanced battery performance.

Battery management system (BMS) testing has different challenges at different phases of the development lifecycle, from hardware prototype, embedded software development, regression testing, validation, to PCBA manufacturing test. A common requirement is simulating the battery in a safe, efficient, and repeatable manner, including charging, discharging, cell balancing, SOx, as well as simulating common battery faults such as over-voltage, over-current, over-temperature, short-circuit, and open circuit.

Hardware-in-the-loop test is the standard approach to validating the design of xEV systems including the battery management system electronics and firmware. Explore an open systems architecture approach to HIL test system implementation including the overall benefits demonstrated by market-leading xEV companies like LG Chem and Jaguar Land Rover.
