Problems solved by technology

[0003] However, when the energy storage battery system is used on a large scale, we should also see a prominent problem of the energy storage battery system: safety issues
The safety of battery energy storage systems, due to the suddenness and hazards of fires in energy storage battery systems, traditional safety fire protection measures cannot effectively suppress the thermal runaway of lithium-ion batteries, which leads to the rapid spread of initial fires, and then evolves into large-scale fires. Large-scale fires, causing major safety accidents and property losses

Abstract

The invention relates to an intelligent fire-fighting system for a battery energy storage system and a working method thereof.The system comprises an energy storage battery unit, a fire-fighting device, a fire-fighting linkage control system and a sound-light alarm device. The energy storage battery unit comprises an electric box, a battery module, a battery management system, a fire induction sensor, a fire-fighting branch pipe and an electromagnetic valve; the fire-fighting branch pipe is arranged at the upper part in the electric box; the electromagnetic valve is arranged at the tail end of the fire-fighting branch pipe; the fire-fighting device comprises a fire-fighting pipeline, a pressure pump, a fire-fighting medium storage tank and an insulating liquid storage tank; the fire-fighting medium storage tank is connected with the fire-fighting pipeline; the insulating liquid storage tank is connected with the fire-fighting pipeline through the pressure pump; the fire-fighting pipeline is connected with a fire-fighting branch pipe in the electric box; the fire-fighting linkage control system is connected with the sound-light alarm device; the battery management system is electrically connected with the battery module, the fire induction sensor and the electromagnetic valve; and the battery management system is further in data communication with the fire-fighting linkage control system. The system is beneficial for improving the working safety of the battery energy storage system.

Description

technical field [0001] The invention belongs to the technical field of battery energy storage, and in particular relates to an intelligent fire-fighting system for a battery energy storage system and a working method thereof. Background technique [0002] The battery energy storage power station is not a power station in the traditional sense, but in a certain time and space, the battery energy storage system can completely act as a power station; and because of its unparalleled response speed and control accuracy, Its frequency modulation and peak shaving effect far exceeds that of all traditional rotary power generation equipment; AGC and AVC functions are inherent capabilities for battery energy storage systems, and there is no suspense and pressure to use; and battery energy storage systems have modules The characteristics of modernized design, flexible configuration, and distributed use make its large-scale grid-connected application possible. At the same time, the bat...
