Energy storage battery safety protection requirements and standards

What is a safety standard for stationary batteries?

Safety standard for stationary batteries for energy storage applications, non-chemistry specific and includes electrochemical capacitor systems or hybrid electrochemical capacitor and battery systems. Includes requirements for unique technologies such as flow batteries and sodium beta (i.e., sodium sulfur and sodium nickel chloride).

Are battery energy storage systems safe?

Battery Energy Storage Systems are vital to modern energy infrastructure. However, they introduce various safety challenges that require attention. Mitigating these risks is essential to ensure the reliability, efficiency, and safety of these systems. Thermal runaway is one of the most serious risks in BESS.

What's new in energy storage safety?

Since the publication of the first Energy Storage Safety Strategic Plan in 2014, there have been introductions of new technologies, new use cases, and new codes, standards, regulations, and testing methods. Additionally, failures in deployed energy storage systems (ESS) have led to new emergency response best practices.

What are the requirements for battery installation & maintenance?

The standard sets out the requirements for the installation and maintenance in buildings of stationary batteries having a stored capacity exceeding 1 kWh, or a floating voltage of 115 V but not exceeding 650 V. Applies to both battery rooms and battery cabinets.

What if energy storage system and component standards are not identified?

Energy Storage System and Component Standards 2. If relevant testing standards are not identified, it is possible they are under development by an SDO or by a third-party testing entity that plans to use them to conduct tests until a formal standard has been developed and approved by an SDO.

How safe is a Bess battery?

The performance of the whole BESS relies on the integrity of its cells. IEC 62133 provides safety benchmarks for portable lithium batteries, including those used in consumer devices. The standard mainly focuses on smaller applications. However, it is also useful for checking cell-level safety in larger BESS.
