Technical FAQs 4

Why are energy storage systems important?

As renewable energy adoption grows, energy storage systems (ESS) have become critical for balancing supply and demand, improving reliability, and supporting grid resilience. To ensure safety, performance, and interoperability, the International Electrotechnical Commission (IEC) developed the IEC 62933 series, a set of globally recognized standards.

Does industry need standards for energy storage?

As cited in the DOE OE ES Program Plan, “Industry requires specifications of standards for characterizing the performance of energy storage under grid conditions and for modeling behavior. Discussions with industry pro-fessionals indicate a significant need for standards” [1, p. 30].

What is an energy storage system (ESS)?

Covers an energy storage system (ESS) that is intended to receive and store energy in some form so that the ESS can provide electrical energy to loads or to the local/area electric power system (EPS) when needed. Electrochemical, chemical, mechanical, and thermal ESS are covered by this Standard.

What is a battery management standard?

A new standard that will apply to the design, performance, and safety of battery management systems. It includes use in several application areas, including stationary batteries installed in local energy storage, smart grids and auxillary power systems, as well as mobile batteries used in electric vehicles (EV), rail transport and aeronautics.
