Continental Breakfast Roundtable Discussions
THURSDAY, JUNE 27
8:30 - 9:30 AM
Join your colleagues and fellow delegates over breakfast for a focused, informal discussion moderated by a member of our speaking faculty. A small group format allows participants to meet potential collaborators, share examples from their own work and
discuss ideas with peers.
TABLE 1: Battery Fire Safety Risks Mitigation and Communication
Haresh Kamath, Senior Program Manager for DER and Energy Storage, EPRI
- Are recent battery fires related to inherent safety risks in the batteries, or are they related to integration failures?
- Are battery users taking unknown risks by reviewing bids chiefly on the basis of price?
- Are battery manufacturers and integrated solution providing enough information on battery failures to their customers and potential customers?
- How can battery users and solution providers work together to enhance better understanding of fire risks and mitigation strategies?
- What standard industry practices should there be about communicating high-profile failures to customers, regulators, and the media?

TABLE 6: Charging Infrastructure for Zero-Emission Heavy-Duty Trucks, Buses and Freight Equipment
Leslie Goodbody, Engineer, Innovative Heavy-Duty Strategies, Mobile Source Control Division, California Air Resources Board
- How important is standardization for conductive charging? Inductive charging?
- For large battery electric fleets, what are the arguments for or against AC vs. DC vs. wireless charging?
- How do demanding duty cycles and routine fast charging affect different battery chemistries in terms of life span and performance?
- What are worker safety concerns with connecting and disconnecting high-power charge ports?
TABLE 7: BMS Test Approaches and Philosophies
Peter Blume, President, Bloomy Controls, Inc.
- Types of BMS testing: engineering verification, software validation, design verification, HALT/HASS, reliability, and manufacturing test.
- Who’s responsible for BMS testing? The vehicle OEM, the cell/module/pack supplier, and/or the contract manufacturer?
- When should you use cell simulation hardware and when should you use real cells for testing the BMS?
- How many cells or modules should you simulate in order to validate a BMS? When and how should you simulate an entire pack?
- What are the capabilities of hardware-in-the-loop (HIL) testing?
- What are the sources of commercially available BMS testing equipment?

TABLE 9: Trade-Offs of Various Battery Structure and Enclosure Materials (Steel, Aluminium, Structural Plastics/Composites)
Andrew Oury, Global Lead Engineer – Power Battery Packs, General Motors
- What materials have battery manufacturers had success with in the past?
- Are there production volume considerations for the best materials? Do lower-volume programs lend themselves to one type of construction while high-volume programs lend themselves to another?
- Do lightweight materials “earn their way in” based on $/kg saved on a BEV?
- What materials have shown promise for management of internal and external fires?
- What influence does the enclosure material have on radiates emissions (EMC)?
- Do certain materials have benefits for crash and underbody protection?
TABLE 10: High-Energy, Fast-Charge Lithium-Ion Cells

TABLE 12: To What Extent Is Regulation Driving the Growth in the xEV Market?
Mike O'Kronley, Executive Director - Corporate Strategy, A123 Systems LLC
- Would the market ever demand xEVs in the absence of regulations?
- What would the timing be?
- Will consumers be forced to drive xEVs or will the market demand them because they are viewed as being better?
- Is there a tipping point?
- When will it occur?
- What effect does economics play in the broad acceptance of xEV?
- Does an xEV need to be cheaper at the time of purchase to be viewed as more attractive?
- Will consumers factor in TCO?
