Energy storage system fire protection operation and maintenance mechanism

What is battery energy storage fire prevention & mitigation?

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.

Does active fire protection work for energy storage systems?

To date there is no publicly available test data that confirms the effectiveness of any active fire protection for energy storage systems, and there are no fire protection systems FM Approved for this application. The ability of active fire protection to stop or prevent Li-ion battery thermal runaway reactions has not been shown.

How to protect battery energy storage stations from fire?

High-quality fire extinguishing agents and effective fire extinguishing strategies are the main means and necessary measures to suppress disasters in the design of battery energy storage stations . Traditional fire extinguishing methods include isolation, asphyxiation, cooling, and chemical suppression .

Why is safety important for the LFP battery energy storage industry?

A BESS made of LFP batteries exploded and caught fire in China, and several firefighters suffered death and mutilation in the blast in 2021 . Therefore, safety is crucial for the high-quality development of the LFP battery energy storage industry. Fig. 2.

How do ESS fire protection systems work?

These layers of protection help prevent damage to the system but can also block water from accessing the seat of the fire. This means that it takes large amounts of water to efectively dissipate the heat generated from ESS fires since cooling the hottest part of the fire is often dificult.

Why do energy storage systems have a high risk of fire?

This is due to the rapid development of the energy storage industry and the continuous expansion of capacity demand. The number of large-capacity energy storage systems has increased, and the probability of accidents has increased. There have been many fire accidents of BESS in United States, Australia and China .
