ESS Safety Working Group | October Newsletter


“Foster confidence in the safety and reliability of energy storage systems.”

In order to encourage open, transparent, and ongoing communication and collaboration among all stakeholders and their associations and organizations in support of the U.S. Department of Energy Office of Electricity (DOE OE) Energy Storage System (ESS) Safety Roadmap, we have started a bi-monthly newsletter to facilitate up-to-date knowledge of news, events, and activities related to ESS safety and reliability. 

If you have relevant content to include in the next issue, email your suggestions to by November 15.  

Recent News


DOE Peer Review and Electrical Energy Storage Applications and Technologies Conference Concluded

The 10th Biennial Electrical Energy Storage Applications and Technologies (EESAT) conference co-located with the DOE OE Energy Storage Program Peer Review took place in San Diego October 9th – 13th. Several presentations were made by the ESS Working Group, and the remaining presentations on safety and reliability will be made available on the event website


Codes and Standards Webinar Presentation Available

In September, the DOE OE Energy Storage Safety Program hosted a webinar in support of the Roadmap that covered the status of key codes/standards relevant to ESS safety. There are many activities occurring in this space that, due to the nature of model codes and standards development, are ongoing and sometimes have set deadlines. Presentations from the American Society of Mechanical Engineers, CSA Group, DNV-GL, FM Global, International Code Council, Institute of Electrical and Electronics Engineers, National Electrical Contractors Association, National Electrical Manufacturers Association, National Fire Protection Agency (NFPA), and UL covered updates to the efforts of these organizations in energy storage safety.

Pilot ESS Safety Training Event was a Success

A one-day training event focused on ESS safety was held on October 19th in Sterling, MA sponsored by the DOE OE ESS Program in collaboration with NFPA and NEC Energy Solutions.  This event sought to bring ESS safety information to the ‘grass roots’ involved in documenting, verifying, and ensuring the safety of ESS installations.  Morning sessions by UL, NFPA, Fire Department of the City of New York, and NEC Energy Solutions followed by a hands-on site visit to the Sterling Municipal Light ESS installation ensured that the attendees had a good experience close to home and gained valuable information on ESS.


Noteworthy Publications

DNV GL Document

Safety, Operation and Performance of Grid-connected Energy Storage Systems

On October 2, 2017, DNV GL officially published a new recommended practice available from their website. The document is intended to cover a broad range of energy storage technologies, including batteries, flow batteries, and flywheels. It approaches safety and performance from a system-level perspective attempting to provide a comprehensive and structured approach to assess both.    

Recommended Practices for Abuse Testing Rechargeable Energy Storage Systems

This technical report describes recommended abuse testing procedures for rechargeable energy storage systems (RESSs) for electric vehicles. This report serves as a revision to the FreedomCAR Electrical Energy Storage System Abuse Test Manual for Electric and Hybrid Electric Vehicle Applications (SAND2005-3123). 

Electrochemical-Engineering-Based Models for Lithium-Ion Batteries—Past, Present, and Future

Abstract of article:  Lithium-ion batteries were first commercialized more than 25 years ago, and today are ubiquitous components in a wide range of applications, including personal electronics, the transportation industry, defense and space applications. As with many energy storage devices, there is a continuous push to create more efficient, better performing, and safer Li-ion batteries. While building and testing new Li-ion batteries is crucial to continued development and improvement, mathematical modeling also plays an extremely important role. Mathematical modeling can reduce the time and materials cost of battery development, and can lead to a better understanding of the fundamental parameters that affect battery performance. This article traces the history of battery modeling, including the critical contributions provided by porous electrode theory some 50 years ago. The role that these early advances have in modeling Li-ion batteries is discussed. Finally, this article touches on the future direction of Li-ion battery modeling, including development of physics-based models to improve battery safety.

Codes and Standards

Focus on Codes and Standards - October Report

The October Codes and Standards Report supports the Safety Roadmap by providing information on current and upcoming efforts being conducted by U.S. standards developing organizations and other entities that are focused on ESS safety. The model codes, standards, and other documents (guidelines, recommended practices, etc.) covered in the report are classified in relation to their scope relative to ESS from the ‘macro to the micro’ and include overarching codes and standards as well as codes and standards for installation, complete ESS, and components.

Upcoming Events and Important Dates

Materials Research Society Fall Meeting  

Summer Ferreira (Sandia National Laboratories) and Judy Jeevarajan (UL) are chairing a symposium on Materials and Design for Resilient Energy Storage at the 2017 MRS Fall Meeting in Boston, MA. The symposium spans November 29th through December 1st with many speakers and posters on energy storage materials and safety related topics. The detailed schedule with authors and abstracts can be found here.
