Electrochemical energy storage safety hazard investigation standard

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.

Do electric energy storage systems need to be tested?

It is recognized that electric energy storage equipment or systems can be a single device providing all required functions or an assembly of components, each having limited functions. Components having limited functions shall be tested for those functions in accordance with this standard.

Do energy storage systems need a CSR?

Until existing model codes and standards are updated or new ones developed and then adopted, one seeking to deploy energy storage technologies or needing to verify an installation’s safety may be challenged in applying current CSRs to an energy storage system (ESS).

What is electrochemical energy storage?

Electrochemical energy storage includes various types of batteries that convert chemical energy into electrical energy by reversible oxidation-reduction reactions. Batteries are currently the most common form of new energy storage deployed because they are modular and scalable across diverse applications and geographic locations.

Do ESS systems and components meet safety standards?

The ability to state, with certainty, that an ESS system or component parts meets the provisions of one or more applicable safety standards supports the timely acceptance of safe ESS systems and components.

What are ESS safety standards?

Considering ESS safety from a ground-up perspective, standards will apply to the smallest parts of the system (e.g., wires, relays, switches, etc.) to address their design, construction, and safety features to serve their intended purpose.
