Problems solved by technology

[0002] At present, more and more lithium battery energy storage systems have been used. Due to the material characteristics of lithium batteries themselves, the possibility of fire and combustion cannot be completely eliminated. Many cases of lithium battery energy storage system fire accidents at home and abroad have made people attach great importance to the safety of the lithium battery energy storage industry, and even restricted the development of the entire lithium battery energy storage industry
[0003] In the existing technology, the fire protection scheme of the energy storage industry mostly adopts the cabinet type heptafluoropropane fire extinguishing device, which performs submerged gas fire extinguishing for the space where the energy storage system is located. For the monitoring and early warning of the thermal runaway of the lithium battery, the existing technology only uses the smoke sensor to collect abnormal information , for other hidden dangers of thermal runaway of lithium batteries, the failure cannot be detected immediately, causing the fire to spread and cause a major accident

Abstract

The invention relates to an energy storage battery safety protection device and system. The temperature information of the battery module and the gas concentration information of the space where the battery module is located are collected through the gas concentration detector and the temperature sensor which are arranged in the cavity. Various fire information is rapidly detected in a small space of a battery PACK level, the thermal runaway state of the lithium battery is judged through the multiple information, and the fire extinguishing agent is automatically released to extinguish fire. The thermal runaway information of the lithium battery can be accurately detected, and the safety protection efficiency is improved.
