Description

BESS fire management system and method

The present invention relates to a system and method for managing a fire in a BESS.

Battery Energy Storage System (hereinafter referred to as 'BESS') refers to an energy storage device, and is a system that stores the produced electrical energy and supplies it when power is needed.

BESS supplements the deficiencies that renewable energy produced by wind power or solar power generation systems is intermittent, can significantly reduce the upgrade and investment costs required for transmission and distribution network upgrades, and stabilize the frequency of the grid system. have. In addition, BESS can reduce the energy cost of general housing and commercial facilities, and can minimize the constraints involved when generating electricity from renewable energy sources.

Although the amount of BESS installation has increased rapidly due to these advantages, considerable property damage is occurring due to fires occurring in the BESS.

Lithium-ion batteries are usually used in BESS, but the fires of lithium-ion batteries are different from general fires.

The cause of the BESS fire is the heat reaction inside the battery caused by internal or external factors of the battery. That is, in an environment in which combustible gas is discharged due to an exothermic reaction, as the internal temperature of the battery rises, the rate of the exothermic reaction accelerates and reaches a limit, a thermal runaway phenomenon occurs in which energy release is instantaneously and rapidly increased. and, in some cases, it is accompanied by a fire or explosion.

Since there are a large number of batteries in a BESS, if thermal runaway occurs in one battery, thermal runaway occurs in a series of adjacent batteries, and it may develop into an explosive fire due to the exhausted combustible gas. Therefore, it is difficult to extinguish a BESS fire with general fire extinguishing facilities and methods.

Due to this, there is a problem in that the fire of the BESS cannot be extinguished until the battery storage is burned out. Also, even if the fire in the BESS is extinguished, thermal runaway may occur again in another battery heated due to the fire, and the fire may recur.

Therefore, there is an urgent need for a method that can prevent thermal runaway as well as effectively suppress the fire before thermal runaway occurs in the BESS.
