STORAGE BATTERIES FOR START-STOP OPERATIONS

Standard:
Scope:

Develop a new Battery Standards that outlines the key performance, usage, design and safety characteristics of low-voltage (<50 volts nominal) Lithium-Ion Battery for use as storage and/or starter batteries in on-road passenger vehicles or trucks, motorboats, tractors, and heavy-duty off-road machines and equipments.

Rationale:

Recent advances in high-power Lithium-Ion (Li-Ion) battery technology has presented a new unique opportunity for developing an improved starter / storage energy storage system in place of the conventional vehicle battery (usually, lead-acid technology). This new battery technology provides a significant improvement on the performance (e.g., cranking power and extended period for accessory loads) and utilization (in both efficiency and physical size & weight), but yet creates a new set of challenges in terms of safety, design robustness and cost. This document will focus on (1) product and functional definitions that describe the uniqueness and similarity of lithium-based technology versus conventional lead-acid, and (2) development of new test procedures for performance and life cycle evaluation to establish new baseline for future non-conventional storage technology.
