Abstract

This document covers recommended information for an objective evaluation of an emerging energy storage technology by a potential user for any stationary application. Energy storage technologies are those that provide a means for the reversible storage of electrical energy, i.e., the device receives electrical energy and is able to discharge electrical energy at a later time. The storage medium may be electrochemical (e.g., batteries), kinetic (e.g., flywheels), electrostatic (e.g., electric double-layer capacitors [EDLCs]), thermal, or some other medium. Devices recharged by non-electrical means, such as fuel cells, are beyond the scope of this document. <br>For the purposes of this document, "emerging" technologies are defined as those technologies recently, or soon to be, made available for sale under customary commercial terms (e.g., defined scope-of-supply, warranted performance). Stationary applications include both standby and cycling operation. <br>The document provides a common basis for the expression of performance characteristics and the treatment of life-testing data. A standard approach for analysis of failure modes is also provided, including assessment of safety attributes. The intent of this document is to ensure that characterization information, including test conditions and limits of applicability, is sufficiently complete to allow valid comparisons to be made. The document does not specify test methods, minimum requirements, or pass/fail criteria. <br>This recommended practice does not describe individual energy storage technologies, nor does it provide guidance on their suitability for a particular application. This document does not cover sizing, installation, maintenance, and testing techniques, except insofar as they may influence the evaluation of a technology for its intended application. <br><strong>Purpose</strong> <br>This recommended practice describes a format for the characterization of emerging energy storage technologies in terms of performance, service life, and safety attributes. This format provides a framework for developers to describe their products. The resulting information assists users in evaluating the possible application of emerging energy storage technologies.
