Battery Breakfast Breakout Discussion Groups
Grab coffee and breakfast and join a discussion group. These are moderated discussions with brainstorming and interactive problem solving, allowing conference participants from diverse backgrounds to exchange ideas and experiences and develop future collaborations around a focused topic.
WEDNESDAY, NOVEMBER 2 | 8:00 AM
Battery Safety Testing and Simulation
Brian Barnett, Ph.D., Vice President, CAMX Power

FRIDAY, NOVEMBER 4 | 8:00 AM
Standards in Safety Evaluation of LIBs
Stephan Hildebrand, MSc, Research Associate, MEET Battery Research Center, University of Münster
- When can you call a battery a safe battery?
- Which safety test can be really transferred to “real life accidents”?
BMS for Lithium-Ion Batteries
Thomas Hoeger, Senior Electrical Power Systems Engineer; Contractor, Advanced Power and Energy Branch, U.S. Naval Surface Warfare Center, Carderock
With the proliferation of lithium-ion batteries, the BMS design has become as critical to battery safety and performance as cell selection. Designers often have a very narrow view as to what comprises the BMS resulting in excess complexity, reduced performance and failure to meet requirements. This discussion identifies the components making up the BMS, from battery cell to system level, and demonstrates utilizing this knowledge to produce an effective BMS and battery that meets performance and safety requirements.
- What is a BMS - functions, safety vs. performance, scope
- Active vs. passive componentry
- Dumb vs. smart
- Data storage
- Communication interfaces
- Design for test
- Requirements and standards
- What's out there
- What's missing
- Necessary vs. optional
- Standardization and cost
Can Thermal Runaway in Lithium-Ion Cells and Batteries Be Predicted?
Judith Jeevarajan, Ph.D., Research Director, Electrochemical Safety, Underwriters Laboratories, Inc.
- Can thermal runaway in li-ion chemistry be predicted?
- Are methods in use today sensitive enough to be able to predict this occurrence?
- Are methods in use today fast enough to react to the start of a thermal runaway?
- Can thermal runaway be stopped if caught early enough?
- What are the signature patterns that may indicate that a particular cell or cells in a battery may be prone to thermal runaway?
Battery Modeling and Simulation

Battery Management and Thermal Safety
Rengaswamy (Srini) Srinivasan, Ph.D., Principal Professional Staff Scientist, Research and Exploratory Development, Applied Physics Laboratory, Johns Hopkins University
- Cell matching protocol may be rigorous before and even after a battery is constructed. From a user or customer perspective, if cells go out-of-match during use, how are they monitored and reported?
- Knowing that SOC impacts the outcome of thermal runaway, what additional efforts are in place to monitor and report SOC during charge and under load conditions?
- Temperature is considered a critical and practical parameter to monitor and be used as a control for thermal safety, yet why do manufacturers cringe when asked to monitor the temperature of every cell in a battery?
- Since temperature is a critical parameter in thermal management, what is the path to help battery manufacturers adapt emerging techniques that monitor cells’ internal temperature?
