Smoke detection device for energy storage battery module and detection method thereof

Abstract

The invention discloses a smoke detection device for an energy storage battery module and a detection method thereof. The smoke detection device is composed of an upper module housing, a lower modulehousing, an optical fiber demodulator, an insulating plate, an upper partition plate support, a top partition plate, an optical fiber sensor, a battery core, a battery core explosion-proof valve, battery core positive and negative pole columns, a battery core connecting block, a bottom tray and mechanical screws. The beneficial effects are that the device carries out real-time monitoring on the independent energy storage battery module, realizes integrated design directly in the battery module, and monitors airflow near the battery core explosion-proof valve through the optical fiber smoke sensor; the optical fiber has strong signal interference resistance and good durability; optical fiber measurement can be conducted in harsh environments of high temperature and high voltage and the like; and the device has a sensitive and accurate monitoring function. According to the method, the monitoring scale of the energy storage battery module is increased, the monitoring efficiency of gas leakage is improved, and safety accidents caused by toxic and harmful gas leakage are greatly reduced.

Description

Technical field [0001] The invention relates to a smoke monitoring method, in particular to a smoke detection device for an energy storage battery module and a detection method thereof, and belongs to the technical field of power equipment monitoring. Background technique [0002] At present, in the field of energy storage containers, the smoke monitoring program proposed for energy storage battery modules is mainly to monitor the entire internal environment of the container by installing a certain number of smoke sensors in the space between the outside of the battery module and the inside of the container. [0003] In the prior art, due to the advantages of high energy density, high cycle times, light weight, and high performance, lithium iron phosphate batteries have gradually become an indispensable and important part of the electrochemical energy storage industry. Used in energy storage projects in various industries. However, during normal operation of lithium iron phosphate...

Problems solved by technology

[0004] In the existing technical solution, due to the small number of smoke sensors, it is impossible to realize a large-scale monitoring function; because the sensor itself is far away from the battery module, and its monitoring signal is also easily interfered by the electromagnetic environment, it is impossible to detect the corresponding smoke in real time and effectively. gas leakage
