Testing, reliability & durability

The Protocol for Uniformly Measuring and Expressing the Performance of Energy Storage Systems
(PNNL-22010) was first issued in November 2012 as a first step toward providing a foundational basis
for developing an initial standard for the uniform measurement and expression of energy storage system
(ESS) performance. Based on experiences with the application and use of that document, and to include
additional ESS applications and associated duty cycles, test procedures and performance metrics, a first
revision of the November 2012 Protocol was issued in June 2014 (PNNL-22010 Rev. 1). As an update of
the 2014 revision 1 to the Protocol, this document (the April 2016 revision 2 to the Protocol) is intended
to supersede the June 2014 revision 1 to the Protocol and provide a more user-friendly yet more robust
and comprehensive basis for measuring and expressing ESS performance. This foreword1 provides
general and specific details about what additions, revisions, and enhancements have been made to the
June 2014 Protocol and the rationale for them in arriving at this April 2016 Protocol (PNNL-22010 Rev.
2 / SAND2016-3078 R).em in arriving at the June 2014 Protocol.

This document provides guidance for an objective evaluation of lithium-based energy storage technologies by a potential user for any stationary application. This document is to be used in conjunction with IEEE Std 1679, IEEE Recommended Practice for the Characterization and Evaluation of Emerging Energy Storage Technologies in Stationary Applications. For the purposes of this document, lithium-based batteries include those secondary (rechargeable) electrochemistries with lithium ions as the active species exchanged between the electrodes during charging and discharging.

Description: The reason for establishing a standard for the Microgrid Energy Management System (MEMS) is to enable interoperability of the different controllers and components needed to operate the MEMS through cohesive and platform-independent interfaces.

1.1 The requirements in this document evaluate the fire characteristics of a battery energy storage system that undergoes thermal runaway. The data generated will be used to determine the fire and explosion protection required for an installation of a battery energy storage system.

This part of IEC 60896 is applicable to lead-acid cells and batteries which are designed for service in fixed locations (i.e. not habitually to be moved from place to place) and which are permanently connected to the load and to the d.c. power supply. Batteries operating in such applications are called "stationary batteries".



Any type or construction of lead-acid battery may be used for stationary battery applications. This part 11 of the standard is applicable to vented types only.



The object of this standard is to specify general requirements and the main characteristics, together with corresponding test methods associated with all types and construction modes of lead-acid stationary batteries, excluding valve-regulated types.



Recommendations on the use of tests for stationary battery application are given in Table A.1.



Recommendations relating the type of cell or monobloc to the use of tests are given in Table A.2.



Statements and claims of basic performance data by the manufacturer shall correspond to those tests.



The tests may also be used for type qualification. 

This part of IEC 60896 applies to all stationary lead-acid cells and monobloc batteries of the valve regulated type for float charge applications, (i.e. permanently connected to a load and to a d.c. power supply), in a static location (i.e. not generally intended to be moved from place to place) and incorporated into stationary equipment or installed in battery rooms for use in telecom, uninterruptible power supply (UPS), utility switching, emergency power or similar applications.
