Scope

This document specifies the normal operating conditions, basic functions, electrical performance, safety performance, mechanical performance, and auxiliary system performance requirements of the converter (referred to as the "energy storage converter") for flow battery energy storage systems. It also proposes requirements for testing rules, test methods, marking, packaging, transportation, and storage. This document applies to three-phase or single-phase converters that use electrochemical flow batteries as energy storage media. This standard applies to converters with an AC-side voltage range of 1kV or less, an AC-side frequency of 50Hz, and a battery-side DC voltage range of 1500V or less. Converters for energy storage systems connected to an AC side with a voltage of more than 1kV through a transformer can be used as a reference. DC/DC converters for flow battery energy storage systems and integrated photovoltaic-energy storage converters with PV ports can also be used as a reference.
