With the rapid development of renewable energy and electric vehicles, energy storage systems play an increasingly important role in modern society. However, fire accidents may occur
Thermal Energy Storage (TES) plays a pivotal role in the fire protection of Li-ion batteries, especially for the high-voltage (HV) battery systems in Electrical Vehicles (EVs). This study covers the application of TES in
In 2019, EPRI began the Battery Energy Storage Fire Prevention and Mitigation – Phase I research project, convened a group of experts, and conducted a series of energy storage site surveys and industry workshops to identify critical research and development (R&D) needs regarding battery safety.
These initiatives have included creating a battery storage fire safety roadmap, developing recommendations and leading practices for designing systems, and training and working with first responders responsible for putting out fires.
As battery storage systems today overwhelmingly utilize lithium-ion technology, the industry must take steps to prevent and mitigate potential fires and preparing effective responses for the rare instances when they occur.
The roles of those assessing safety also influence their perspective and priorities. For example, some fire protection professionals are experienced in hazardous material fires, while others have specific experience with safety events involving lithium-ion or other battery storage chemistries.
EPRI is currently working on a range of resources to help improve the safety of battery energy storage systems called the Project Lifecycle Safety Toolkit. It will include everything from data sets to white papers and guidebooks that provide practical steps to mitigate the risk of a battery fire and to optimize the response in case it occurs.
The combination of high energy densities and flammable electrolytes puts high demands on associated fire protection systems. ◼ Statistics1 show that electrical fires account for over 25% of major fire losses in industrial companies. ◼ The importance of Li-ion battery storage systems has increased dramatically in recent years.
