Covers requirements for battery systems as defined by this standard for use as energy storage for stationary applications such as for PV, wind turbine storage or for UPS, etc. applications.
This reference design focuses on an FTM utility-scale battery storage system with a typical storage capacity ranging from around a few megawatt-hours (MWh) to hundreds of MWh.
Identification of the right standard is crucial—a Li-ion DC battery module specification needs to be verified by a standard for Li-ion battery modules, while an ESS specification needs to be verified by an ES performance standard.
That said, the evolution in codes and standards regulating these systems, as well as evolving battery system designs and strategies for hazard mitigation and emergency response, are working to minimize the severity of these events and to limit their consequences.
Battery Energy Storage System Evaluation Method Report describes a proposed method for evaluating the performance of a deployed BESS or solar PV-plus-BESS system.
This overview of currently available safety standards for batteries for stationary battery energy storage systems shows that a number of standards exist that include some of the safety tests required by the Regulation concerning batteries and waste batteries, forming a good basis for the development of the regulatory tests.

The rapid deployment of battery storage systems in homes, industries, and utilities necessitates standardization. Without a unified framework, systems may fail, pose safety risks, or operate inefficiently. The IEC standard for battery energy storage system provides benchmarks for:
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.
Future standards may focus more on: The IEC Technical Committee 120 is actively updating existing documents and drafting new ones to address emerging needs. The IEC standard for battery energy storage system is the foundation for the safe and efficient growth of energy storage worldwide.
The IEC standard for battery energy storage system is the foundation for the safe and efficient growth of energy storage worldwide. By following these standards, stakeholders can ensure reliability, performance, and safety across all applications — from residential rooftops to national grid infrastructure.
