Scope
This Recommendation identifies the main needs and applications of stationary electrical energy storage for information and communication technology (ICT) sites such as back-up on different grid quality and cyclic use of renewable energy systems. It also provides possible selection criteria for the correct choice for the end system. The topics considered are: ?C families of electrical energy storage@ such as batteries or supercapacitors; ?C technologies types and their main properties; ?C adaptation to requirements (e.g.@ functionalities@ technology availability@ electrical characteristics@ environmental adaptation@ maintenance type@ cost); ?C national or regional rules and regulations. The Recommendation highlights the need for evaluation methods that are complementary to existing battery standards as they allow different time-frames including shorter tests compared to common energy storage industry tests. This Recommendation is Part 1 of a series of Recommendations that cover energy storage technologies (e.g.@ battery@ supercapacitor) applicable to stationary telecom/ICT equipment used in telecom networks@ data centres and customer premises equipment (CPE).
