Problems solved by technology

However, if the influence of the ambient temperature is not considered, it will cause misjudgment or untimely judgment, and the battery catches fire quickly and releases a large amount of heat, resulting in thermal runaway of the battery. If the battery with potential fire risk is not handled in time, it will cause the fire of the battery pack. spread or explode

Abstract

The invention discloses an automatic fire extinguishing device and system for battery storage. The automatic fire extinguishing device comprises a battery storage area, a battery pack, infrared temperature sensors, a fire extinguishing agent storage module, a data transmission module, a control module and an isolation device, the infrared temperature sensors comprise a first infrared temperature sensor and a second infrared temperature sensor, the first infrared temperature sensor is distributed inside the battery storage area, and the second infrared temperature sensor is arranged outside the battery storage area and connected with the control module; the isolation device is connected with the control module, isolates a target battery pack area corresponding to the alarm data according to an isolation instruction of the control module, locks the target battery pack area, and returns an isolation completion signal to the control module; and the fire extinguishing agent storage module releases a fire extinguishing agent to the target battery pack area according to the fire extinguishing instruction of the control module. The effects of quickly disposing a fire area, pre-judging the potential risk area in advance, reducing an affected area and reducing the fire influence are achieved.

Description

technical field [0001] Embodiments of the present invention relate to battery management technology, and in particular to an automatic fire extinguishing device and system for battery storage. Background technique [0002] With the rapid development of the new energy vehicle industry, the safe storage of batteries is a key safety area. Since lithium battery materials are flammable and rich in heavy metals, battery recycling companies are also facing dangers such as fire and environmental pollution. [0003] Traditional fire extinguishing devices are generally monitored based on parameters such as battery temperature and smoke, and extinguished after the parameters reach a certain threshold. However, if the influence of the ambient temperature is not considered, it will cause misjudgment or untimely judgment, and the battery catches fire quickly and releases a large amount of heat, resulting in thermal runaway of the battery. If the battery with potential fire risk is not ha...
