Battery Management System Testing

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.

NIWEEK 2016 BTS Wrap Up - Top 5 and more..

August 19, 2016

NIWeek 2016 was a great success for Bloomy and for the Bloomy BTS team. From touching down in Austin Sunday morning through our Thursday departure, we had an extraordinary 5 days of connecting to partners, customers, vendors, and friends. Thank you to everyone who helped make this arguably the best NIWeek yet. There is much to recap, so we'll start with our top 5 listing from July and go from there.

Battery Test and Simulation: Top 5 things to take note of at NIWeek 2016

July 29, 2016

NIWeek 2016 kicks off Monday August 1st with the Exhibition Hall doors opening at 5:30PM. Bloomy’s BTS (Battery Test and Simulation) team has been hard at work preparing for what looks to be the most exciting NIWeek for us yet! If you plan to be at the show, here are 5 exciting things to look out for, and of course please be sure to come by our booth (Booth #205) to say hello. For those who won’t be at the show, I’ll be posting a conference summary soon after we return, with relevant links to the highlights and to materials that will have been presented.

Presented by Peter Blume at the Advanced Automotive Battery Conference (AABC) 2016 in Detroit, MI

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.

Battery Test and Simulation News at Bloomy

May 31, 2016

Bloomy’s Battery Test and Simulation (BTS) team continues its participation at industry conferences in 2016, following a successful presence at the ESA (Energy Storage Association) 26th Annual Conference this past April in Charlotte, NC. At the event, Peter Blume spoke on "ESS Performance Testing for US DOE Energy Storage Smart Grid Demonstration Program". To view the presentation, see ESS Performance Testing - ESA 2016.

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.
