Problems solved by technology

In fact, the analysis of historical accidents shows that conventional fire detection methods such as temperature, flame, and smoke are not enough to detect the occurrence of fire before the thermal runaway of lithium batteries develops to the stage of severe runaway.

Embodiment Construction

[0046] like figure 1 As shown, the energy storage system has m×n energy storage units, and the m×n energy storage units are placed in the container body 7 . The battery management system 8 (ie BMS) divides the energy storage system into a total of m×n address units, that is, the battery management system 8 can The capacity distinguishes the granularity, and the energy storage unit is turned off (cut off) to prevent the deterioration or spread of thermal runaway, and prevent the occurrence of fire.

[0047] The very early warning equipment for fire of the energy storage system in this embodiment includes a sampling pipeline, a sampling and analysis host 1 and m×n solenoid valves 2, and the values ​​of m and n are optimally set according to the modular design type of the energy storage system. The sampling pipeline includes a sampling calibration pipe 3 , m sampling trunk pipes 4 and m×n sampling branch pipes 5 corresponding to m×n energy storage units one-to-one. Each samplin...

Abstract

The invention discloses an energy storage system fire extremely early warning device, control system and method, the early warning device comprises a sampling pipeline, a sampling analysis host and m * n solenoid valves, the sampling analysis host comprises a first multi-channel switching valve, a second multi-channel switching valve, an air pump, a host controller and k + 1 gas sensors; circulating sample introduction of a gas sample to be detected is completed through the first multi-channel switching valve, switching of a working gas sensor is completed through the second multi-channel switching valve, the recovery time of the gas sensor is saved, the positioning precision of a hidden danger energy storage unit is improved, meanwhile, the flexibility and applicability of the early warning equipment can be improved, and the working efficiency is improved. And the equipment purchase and maintenance cost is reduced.

Description

technical field [0001] The invention belongs to the field of energy storage system safety, and in particular relates to a fire extremely early warning device, a control system and a method for an energy storage system. Background technique [0002] Electrochemical energy storage system is currently the most mature energy storage technology route. However, the fire safety of electrochemical energy storage system is indeed a key bottleneck restricting the large-scale promotion of mainstream lithium-ion battery energy storage. The reasons for the difficulty of fire fighting in the energy storage system are: (1) As an energetic substance with high energy density, it burns violently and spreads rapidly; (2) During the thermal runaway of the energy storage unit, a large amount of toxic and combustible flue gas is released, which is stored in the enclosed space. In the risk of explosion, it is very easy to cause the accident to spread; (3) The energy storage system is densely stack...
