Accurate Circuit Model For Predicting The Performance Of Lead-Acid Agm Batteries, Wenxin Peng

UNLV Theses, Dissertations, Professional Papers, and Capstones

Energy storage technologies are becoming of great importance in many modern electrical systems. In particular, electrochemical batteries are rapidly gaining wide-spread application in transportation systems as well as in the electric utility sector, where they provide a means to convert non-dispatchable renewable resources into dispatchable generation sources. Hence, accurate battery models are needed during the design stage of such systems to forecast future performance.

A variety of models with a varying degree of complexity and accuracy currently exist that predict battery behavior. In the proposed paper, an existing battery model is modified to account for some battery irregularities while maintaining …

"Buried-Anode" Technology Leads To Advanced Lithium Batteries, National Renewable Energy Laboratory

Publications (E)

A technology developed at the National Renewable Energy Laboratory has sparked a start-up company that has attracted funding from the Advanced Projects Research Agency-Energy (ARPA-E). Planar Energy, Inc. has licensed NREL's "buried-anode" technology and put it to work in solid-state lithium batteries. The company claims its large-format batteries can achieve triple the performance of today's lithium-ion batteries at half the cost, and if so, they could provide a significant boost to the emerging market for electric and plug-in hybrid vehicles.
