Qualification methods for Class 1E vented lead acid batteries and racks to be used in nuclear power generating stations outside primary containment are described in this standard. Qualifications required by IEEE Std 308(TM) can be demonstrated by using the procedures in this standard in accordance with IEEE Std 323(TM). The application of batteries in nuclear power generating stations can be divided into two sections: duty cycles equal to or less than 8 h and duty cycles greater than 8 h. A process to demonstrate qualifications for both applications is provided in this standard.

Es ist notwendig, dass die Zustände aller Zellen innerhalb einer Lithium-Ionen-Batterie bekannt sind, um einen sicheren und optimalen Betrieb zu gewährleisten. Zur Ermittlung dieser Zustände werden in dieser Arbeit drei neue Methoden zur verteilten Zustandsschätzung hergeleitet, welche auf fraktionalen Modellen und dem Kalman-Filter basieren. Mithilfe dieser Verfahren lassen sich zusätzlich die Teilströme der Batterie schätzen, wodurch sich Sensoren einsparen lassen. It is necessary that the states of all cells of a lithium ion battery are known to guarantee a safe and optimal operation. In order to determine these states, three new methods for distributed state estimation which are based on fractional models and on the Kalman filter are derived in this work. Using these techniques, the branch currents of the battery can be additionally estimated to save sensors.

Superseded by IEEE Std 650-2006. Methods for qualifying static battery chargers and inverters for Class 1E installations in a mild environment outside containment in nuclear power generating stations are described. The qualification methods set forth employ a combination of type testing and analysis, the latter including a justification of methods, theories, and assumptions used. These procedures meet the requirements of IEEE Std 323-1983, IEEE Standard for Qualifying Class 1E Equipment for Nuclear Power Generating Stations.

Application of this standard includes: (1) Stationary battery energy storage system (BESS) and mobile BESS; (2) Carrier of BESS, including but not limited to lead acid battery, lithiumion battery, flow battery, and sodium-sulfur battery; (3) BESS used in electric power systems (EPS). Also provided in this standard are alternatives for connection (including DR interconnection), design, operation, and maintenance of stationary or mobile BESS used in EPS. Introduction, overview, and engineering issues related to the BESS are given.
