Innovative energy storage technology for stationary use - Part 2: Battery
|Publication Date:||1 November 2018|
The present Recommendation contains the main requirements for evaluating appropriate innovative batteries for stationary use for powering ICT equipment in telecom sites, active network units and data centres or customer premises with standardized power interfaces in -48V, up to 400 VDC or 12V.
Based on the general selection and evaluation method proposed in [ITU-T L.1220], the present Recommendation introduces the main battery technologies, characteristics and the method to select, evaluate and test battery products adapted to a defined application.
This Recommendation describes the selection criteria and possible tests for making the appropriate or optimal choice of battery technology for an ICT stationary application. This includes mechanical performance, electrical performance, (voltage, current, power and capacity ratings, efficiency and self-discharge, etc.), environmental performance (temperature range), lifetime performance (cycling and calendar life, tolerance of partial charge and depth of discharge), installation, operation and maintenance complexity (parallel operation), safety (risk to and protection of humans and environment, error and fault tolerance), management/monitorin
This Recommendation specifies evaluation methods and tests which complement those of existing relevant standards requirements.
