SAE 2013 Electric Vehicle Battery Cell Size Standardization Symposium
Technical Session Schedule
Wednesday, October 23
OEM Perspective on Battery Cell Size Standardization: Includes Keynote Presentation by Neil Maguire, JuiceBox Energy, Inc
(Session Code: BCS200)
Room Erie, Ontario, Huron 8:00 a.m.
This Symposium will begin with the companies that stand to benefit the most from standardizing battery cells for the electric and hybrid vehicle segment: the OEMs. The number of standards dealing with sizes worldwide has dropped by 50% over the last few years allowing them to concentrate on vehicle platform designs and not having to worry about fitting new sizes into their vehicle architectures. Speakers will discuss their philosophies on standardization and why it encourages adoption of electric and hybrid vehicles on the road in greater numbers.

|Opening Keynote: Accelerating Technology Adoption through Standardization
Innovation and creativity in basic science unleashes new technologies that solve long standing challenges and result in the introduction of new products and applications to the market. The adoption of these technologies however, ultimately rests in the engineering process of not just getting the first product to work but ensuring that millions of products never fail. At the same time, the engineer must always understand the path towards cost reduction while meeting evolving consumer expectations.
The large scale lithium-ion cell industry continues to produce innovative materials and electrochemical advances. And with the first round of xEV's now available in the market, the engineering process of getting millions to never fail is long underway. However, to rapidly grow the adoption of xEVs the focus is now on cost reduction and broadening the portfolio of vehicle models.
We have seen this challenge before in the battery industry. As with the small scale lithium-ion cell developments in the 1990s, the exterior packing of advanced materials is not a differentiator for manufacturers. Likewise, the opportunity at hand is to adopt a set of common cell sizes. A set of standard cell sizes does not prevent innovation and creativity at the electrochemical level rather it provides a platform for rapid introduction of new technologies, enables significant manufacturing cost reduction, enables faster time-to-market for pack developers and improves safety.

|Discussion of the development of ISO/IEC PAS 16898:2012 "Electrically Propelled Road Vehicles -- Dimensions and Designation of Secondary Lithium-ion Cells"
Starting with a list of automotive battery cell size standards proposed by the German VDA, ISO convened a workgroup effort within TC22 SC21 to document the international position on “Electrically propelled road vehicles -- Dimensions and designation of secondary lithium-ion cells”. The US position was collected by the USABC and communicated through ANSI to ISO. From international contributions, the number of contributed sizes toward the international standard was large. Ultimately the ISO vote was for a Publicly Available Specification (PAS) rather than a standard. The US and German contributions from the USABC and VDA, respectively, to the ISO/IEC PAS 16898:2012 will be presented. The size metrics used in the ISO PAS will be described. Chrysler’s opinion on vehicle battery design benefits and other implications associated with standardizing battery cell sizes will be discussed.

Lithium Ion battery size standardization at the lowest level represented by cell size is a challenging question for vehicle and battery manufacturers. History of battery size standards for starter batteries has shown size standards can be effectively developed. Efforts to catalogue different automotive LiIon battery sizes are under way. Several factors must be considered when developing standard cell sizes as well as in determining value and benefits. Some of these will be discussed and debated. Finally, the drivers and areas of greatest focus towards size standards will be suggested for discussion.
