24 channels of fault insertion and switching for the Battery Simulator 1200
The Battery Fault Insertion Unit (FIU) provides intelligent switching of cell-simulation channels for the Battery Simulator 1200. The switching capability enables simulation of open-circuit and short-to-rail fault conditions on any cell channel for the purposes of battery management system (BMS) testing.
Lithium-Ion batteries, such as those used in hybrid and electric vehicles, require sophisticated battery management systems (BMS) to balance the cells, optimize performance and ensure safe operation. In this very brief video clip recorded at NIWeek 2015, Hector provides an overview of Bloomy's desktop demonstration version of the BMS HIL Test System.
The key to accelerating development of electrified vehicle (xEV) batteries is to decouple the interdependencies which exist between development of battery management electronics and firmware, and the development of cells and packs. Advanced modeling, simulation, and test techniques can be used to develop the electronics and firmware concurrently with the cells and packs, thereby expediting xEV battery development cycles.

(and practical solutions)
Presented at the Advanced Automotive Battery Conference (AABC) in Detroit, MI, USA on June 16, 2015 by Peter Blume of Bloomy.
This document offers a solution to providing a flexible, cost-effective production test system for several designs of battery balancing, monitoring, and management system (BMS) printed circuit board assemblies.
Bloomy’s participation at The Battery Show Expo for Advanced Batteries in Novi, MI consisted of an exhibition, a presentation, and participation in the open-tech forum, all of which allowed attendees to learn valuable BMS test insights.
Simulate and measure BMS activity
The BMS Environmental Test System is a configurable platform simulating the essential signals used by Battery Management Systems (BMS) and cell monitoring modules with the ability to perform environmental testing on multiple BMS units simultaneously. The system implements single point value testing to evaluate specific BMS functions such as cell over and under voltage scenarios, cell leakage current, lost communications, or faulty system I/O.

Challenge
Bloomy and RDVS were tasked with developing a system providing the ability to rapidly produce Battery Management System (BMS) algorithms on physical hardware, and safely test the unit against different battery chemistries, fault scenarios, and drive profiles.
