IEEE P1679/D3-2019 Draft Recommended Practice for the Characterization and Evaluation of Emerging Energy Storage Technologies in Stationary Applications
IEEE - The Institute of Electrical and Electronics Engineers@ Inc.
Scope
This document covers recommended information for an objective evaluation of an emerging or alternative 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. 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). ??Alternative?? technologies are those that are currently mature but are less well-known or as frequently deployed as traditional technologies such as lead-acid and nickel-cadmium batteries. Stationary applications include both standby and cycling operation. 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. 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. Purpose This recommended practice describes a format for the characterization of emerging or alternative 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 or alternative energy storage technologies.
