The invention discloses system for thermal management and fire-fighting system equipment for an electrochemical energy storage square cabin, and solves defects existing in a heat management system ora fire-fighting system of an existing energy storage square cabin. The equipment comprises a heat management system, a battery module and a fire fighting system; the heat management system comprises an air cooling pipeline, a refrigerating machine, a total heat exchange unit, a gas monitoring module and a ventilation electromagnetic valve; the fire-fighting system comprises a fire-fighting agent mist spray release pipeline, a fire-fighting agent shower release pipeline, a fire-fighting agent conveying pipeline, a fire-fighting host, a flame detector, a temperature monitoring module and a secondary water fire-fighting connecting pipeline. According to the equipment, through the cooperation of the air cooling pipeline, the refrigerating machine, the temperature monitoring module, the flamedetector, the fire-fighting host and the like, the defects and shortcomings existing in the thermal management system or the fire fighting system of the existing energy storage square cabin are effectively overcome, the safety and the reliability of the energy storage square cabin are guaranteed through the integrated top level design, and the operation risk and the maintenance cost of the energystorage square cabin are reduced.

Description

Technical field [0001] The invention relates to the field of energy storage shelters, in particular to a system equipment for thermal management and fire protection of electrochemical energy storage shelters. Background technique [0002] At present, energy storage methods are mainly divided into three categories: mechanical energy storage, electromagnetic energy storage, and electrochemical energy storage. Among the various types of energy storage, electrochemical energy storage projects account for the largest proportion and are the key research direction; in electrochemical energy storage Among them, lithium-ion batteries account for the largest number of projects and installed capacity, and their growth rate is also the fastest. It has become the fastest growing electrochemical energy storage technology. Energy storage shelter is a kind of electricity storage method that uses lithium ion battery as energy storage medium, and is a kind of chemical energy storage. [0003] The e...

AI Technical Summary

Problems solved by technology

[0003] The existing thermal management system of the energy storage shelter has disadvantages such as uneven temperature field distribution and low cooling efficiency; there is no effective information interaction between the existing fire management system and the thermal management system, and it cannot prevent thermal runaway of lithium-ion batteries. Early warning signals are provided. After thermal runaway of lithium-ion batteries, reliable and continuous fire extinguishing and cooling cannot be carried out, which may easily cause major disasters to equipment or people.

In addition, the existing thermal management system and fire protection system have disadvantages such as complicated maintenance and high operation and maintenance costs
